Recommendations following judicial abrogation of error of law rule

In our Discussion Paper No 95 on Recovery of Benefits Conferred Under Error of Law, we sought views on provisional proposals that the rule precluding recovery of benefits conferred under error of law should be abrogated by statute.

^[11]

Morgan Guaranty Trust Company of New York v Lothian Regional Council.^[12]

^[13]

No statutory safeguard against reopening payment transactions. There remained the second main provisional proposal in Discussion Paper No 95, namely, a statutory safeguard which would prevent persons who had paid a purported debt in accordance with a common understanding, or settled view, of the law later overturned by a judicial decision from recovering lest a wide circle of closed transactions be opened up whenever such a decision was made.

Amendment of statutory provisions on recovery of local government non-domestic rates. In our Discussion Paper No 100, we reviewed among other things the statutory provisions for the recover of local government council tax and rates. We sought views on proposals to harmonise some of the provisions on rates with the Woolwich rule.

^[19]

^[20]

^[21]

No recommendation to amend statutory provisions on recovery of central government taxes and council tax. In our Discussion Paper No 100, we also reviewed the statutory provisions for the recovery of the principal central government taxes and charges.

Consultation on possible review of the general law on unjustified enrichment

Our research for Discussion Papers Nos 95, 99 and 100 revealed much that is wrong with the present law on unjustified enrichment. In our Discussion Paper 99 we sought views on whether a new type of approach based on broader and more liberal grounds of recovery than the existing grounds should be examined as part of a general review of the law of unjustified enrichment.

^[30]

^[31]

Constitutionality

In Part 3 below, we recommend legislation on refund of non-domestic rates. The Scotland Act 1998 expressly mentions obligations arising from unjustified enrichment as one of the branches of Scots private law over which the Scottish Parliament will have legislative competence.

^[32]

^[33]

**Part 2 Possible Amendments of Common Law Consequential on Morgan Guaranty and Woolwich Cases**

In this Part, we consider in Section A whether a statutory safeguard should be introduced barring common law claims reopening payment transactions completed on the faith of a settled view of the law subsequently changed by judicial decision. Section B considers whether the "Woolwich rule"

(2) Change by judicial decision in the "settled view" of the law: statutory safeguard against reopening settled transactions?

Background

In our Discussion Paper No 95 on Recovery of Benefits conferred under Error of Law,

^[42]

(a) in the law; or

(b) in the common understanding of the law,

effected by a judicial decision in civil proceedings, and a payment was previously made in accordance with the law, or the understanding of the law, before that change, the payment should not be recoverable by reason only of that change.^[43] This proposal was based on legislation in New Zealand and Western Australia.^[44] Its purpose was to protect the security of receipts and the finality of closed payment transactions. We argued that the safeguard was too important to be left to the uncertainties of judicial decisions.^[45]

Commenting on Discussion Paper No 95, the Court of Session judges pointed to the oddity of providing that a payment is not to be recoverable by reason of a "change" in the law. If a judicial decision does indeed effect a change in the law, a payment made on the faith of the law as it stood before the change would not have been made under error of law and therefore would not be recoverable on the ground of error in law. In our Discussion Paper 99, therefore, we accepted that any provision introducing the safeguard should not refer to "a change" in the law. If the courts do change the law, the reference is unnecessary; if they do not (because of the declaratory theory), it would be inappropriate for statute to state that they do.

2.7

As the judges recognised, however, there remains the question whether, where a judicial decision overturns a "common understanding", or (to use the Law Commission's terminology

^[46]

The Morgan Guaranty case and "the floodgates argument". It could not be assumed that those consultees who approved a statutory safeguard would necessarily adhere to that view in the new situation created by the decision in Morgan Guaranty.

^[47]

^[48]

Lord Clyde considered that the floodgates argument had less force then (1995) that at the time when the error of law rule was affirmed by the Glasgow Corporation case in 1959.

^[49]

^[50]

Woolwich

^[51]

"I do not believe that it can be so confidently affirmed today that the public interest in the finality of settlement transactions should outweigh the interest of private individuals in recovering money which, in a proper understanding of the law, they were never due to pay".^[52]

Third, it was not obvious why error in the construction of a standard form contract which might affect very many individuals should enable repetition^[53] while error in construing public legislation would not.^[54]

The Law Commission. Meantime in England and Wales, the Law Commission recommended statutory safeguards against opening the floodgates to, first, private law actions of repayment brought by third parties where a judicial decision changes "a settled view" as to liability under private law

^[55]

^[56]

New consultation. In our Discussion Paper No 99

^[57]

^[58]

^[59]

(a) The "declaratory" and "settled view" theories

The English Law Commission pointed out that where the law is changed by legislation, a payment made complying with the pre-existing law is irrecoverable because legislation (unless it provides for retrospection) does not have retrospective effect.

^[60]

judicial decision

The declaratory theory. On one theory, the judges do not "change" the law but merely "declare" what the law is and always has been. In other words a judicial decision declaring the law operates retrospectively. So where a payment is made before a judicial decision declaring the law to be different from a previous settled view thereof, and the payment had been made on the faith of, or in accordance with, that settled view, then the payment is, on this "declaratory theory", mistaken and recoverable.

2.14

In our Discussion Paper No 95

^[61]

^[62]

^[63]

Kleinwort Benson v Lincoln City Council

^[64]

The "settled view" theory. The English Law Commission took the view that it should not matter whether a change occurs through legislation or judicial decision: the payment should not be recoverable because in their view in substance there has been no mistake.

^[65]

^[66]

^[67]

"that a restitutionary claim in respect of any payment, service or benefit that has been made, rendered or conferred under a mistake of law should not be permitted merely because it was done in accordance with a settled view of the law at the time, which was later departed from by a subsequent judicial decision".^[68]

"Settled view" theory inconsistent with declaratory theory of judicial law-making

We found it difficult to reconcile the "settled view" theory with the declaratory theory of judicial law-making. To say that "where the court changes a settled view of the law there has been in substance no error" seemed to us to presuppose, contrary to the declaratory theory, that the courts do change the law. How far the declaratory theory was correct or false, and whether it applied in the law of unjustified enrichment to open up past transactions, was a difficult and controversial question which this Commission could not resolve. In our Discussion Paper No 99, we remarked that it would be fallacious to say that the judges never change the law: as Lord Reid has observed, that is a fairy-tale.

^[69]

^[70]

^[71]

Rejection of the "settled view" theory by the Kleinwort Benson case

The question has now been answered by the English case of Kleinwort Benson Ltd v Lincoln City Council

^[72]

The arguments of the minority judges

The minority (Lord Browne-Wilkinson

^[73]

^[74]

^[75]

This adoption of the "settled view" theory was supported by two policy reasons. First, the prospect of transactions being reopened many years after the event by a subsequent judicial decision should not be favoured by the law, especially in the field of commerce. The defendant would not always be able to rely on a defence of change of position. Certainty and finality were twin policy objectives of the highest order in formulating legal principles.

^[76]

^[77]

^[78]

The arguments of the majority judges

In giving the leading judgment for the majority,

^[79]

"the law which the judge then states to be applicable to the case before him is the law which, as so developed, is perceived by him as applying not only to the case before him, but to all other comparable cases, as a congruent part of the body of the law. Moreover when he states the applicable principles of law, the judge is declaring these as constituting the law relevant to his decision. Subject to consideration by appellate tribunals, and (within limits) by judges of equal jurisdiction, what he states to be the law will, generally speaking, be applicable not only to the case before him but, as part of the common law, to other comparable cases which come before the courts, whenever the events which are the subject of those cases in fact occurred".^[80]

Lord Goff concluded that the declaratory theory was not an aberration of the common law, that it does not presume the existence of an ideal system of the common law revealed by judges, but that it does mean that their decisions have retrospective effect.

^[81]

^[82]

^[83]

Lord Hoffmann said that the "settled view" theory looks at the question of what counts as a mistake in too abstract a way, divorced from its setting in the law of unjust (or unjustified) enrichment.

^[84]

"The problem arises because (1) the law requires that a mistake should have been as to some existing fact or …the then existing state of the law but (2) a judicial statement of the law operates retrospectively. So the question is whether the retrospectivity of the law-making process enables one to say that holding a contrary view of the law at an earlier stage was a mistake. This question cannot be answered simply by taking a robust, commonsense definition of a mistake and saying that one does not believe in fairy stories … The commonsense notion of a mistake as to an existing state of affairs is that one has got it wrong when, if one had been better informed, one could have got it right. But common sense does not easily accommodate the concept of retrospectivity. This is a legal notion…. The lawyer would …start by considering why, in principle, a person who had paid because he held some mistaken belief should be entitled to recover. The answer is that it is prima facie unjust for the recipient to retain the money when, if the payer had known the true state of affairs, he would not have paid."^[85]

Under English law since Kelly v Solari,^[86] in the case of a mistake of fact, the mistaken payer can recover even if he could have discovered the true state of affairs. (The same has been true of Scots law since the Morgan Guaranty case in 1995 which abrogated the requirement that an error of fact or law must be excusable for an action of repetition to lie based on error.)^[87] In Lord Hoffmann's view the distinction between mistakes of fact and law turned upon the point that in principle the truth or falsity of any proposition of existing fact could have been ascertained at the time, whereas the law, as subsequently declared by the court, could not. He did not think that this should make a difference to a claim in unjust enrichment. In both cases the state of affairs was not what the payer thought: in mistake of fact, because things were actually not what he believed them to have been and, in mistake of law, because of the retrospectivity of the court's decision. In his view, in order to avoid unacceptable anomalies, this retrospectivity required that a payer claiming restitution should be treated as making a mistake of law.^[88]

"Imagine a client who has paid under what he thought to be a legal obligation. He had not consulted a lawyer at the time, but seeks advice after a case in the House of Lords which decides that the obligation was void. The lawyer tells him that according to the House of Lords, he need not have paid. He asks whether he can recover his money on the grounds of mistake. On the 'settled view' theory, the lawyer has to say: 'No, because if you had consulted me at the time, I would have told you that you were certainly right to pay. Therefore you made no mistake.' The client asks: 'Does that mean that the obligation was actually valid? If so, what has made it invalid?' The lawyer has to answer 'No, the House of Lords has told us that it was always void. Nevertheless, you made no mistake. On the other hand, if lawyers had regarded it as a doubtful point, or if any lawyer would have told you then that the obligation was void, so that it would have been extremely foolish of you not to have sought advice, then you would have been able to recover.'

"My Lords, it seems to me that the imaginary client would have great difficult in understanding how these distinctions can arise out of a rule giving a remedy for unjust enrichment. In each case he thought that the obligation was valid and it has subsequently turned out that it was not. In principle, the question should not turn upon what other people might have thought was the law but upon what he thought was the law. And this has turned out to have been wrong, however many lawyers might have agreed with him at the time. So there ought to be a remedy in all cases or none."^[89]

Lord Hope's approach was slightly different. He thought it preferable to avoid being drawn into any discussion as to whether a particular judicial decision changed the law or was merely declaratory.

^[90]

"to face up to the fact that every decision as to the law by a judge operates retrospectively, and to concentrate instead on the question - which I would regard as the critical question - whether the payer would have made the payment if he had known what he is now being told was the law. It is the state of the law at the time of the payment which will determine whether or not the payment was or was not legally due to be paid, and it is the state of mind of the payer at the time of payment which will determine whether he paid under a mistake. But there seems to me to be no reason in principle why the law of unjust enrichment should insist that that mistake must be capable of being demonstrated at the same time as the time when the payment was made. A mistake of fact may take some time to discover. If there is a dispute about this, the question whether there was a mistake may remain in doubt until the issue has been resolved by a judge. Why should this not be so where the mistake is one of law?"^[91]

Remarking that the "settled view" safeguard was incapable of precise definition, caused unpredictable absurdities and was lacking in principle, Lord Hope concluded that this Commission's work had show a need for caution which was fully justified.^[92]

Introduction of statutory safeguard a question of policy not principle

Two consequences of the Kleinwort Benson case may be noted. First, the case for statutory reform may now be argued against a stable common law background. We now know that, under the declaratory theory of judicial law-making, a judicial decision is given retrospective effect in the law of unjustified enrichment so as to permit recovery of past payments made, or other benefits conferred, in accordance with a settled view of the law overturned by a later judicial decision.

2.25

Second, the decision, confirming the impression given by the Morgan Guaranty case, makes it virtually certain that the Scottish courts will not introduce a "settled view" safeguard at common law (except possibly in tax cases thought that possibility seems remote).

^[93]

^[94]

It is still arguable that a statutory safeguard may be needed following abolition of the error of law rule to protect the finality of closed transactions and the security of receipts.

^[95]

"That this whole topic is one of great difficulty can perhaps best be seen in the Scottish Law Commission's Judicial Abolition of the Error of Law Rule and its Aftermath (Scot Law Com Discussion Paper no 99) (1996) in which the rival arguments for and against legislative reform are rehearsed in some detail, and the difficulties exposed. This division of opinion does not encourage statutory adoption of a provision in these or comparable terms, still less its recognition as part of the common law of this country".^[96]

On the other hand, as we have seen, the need for a statutory safeguard was left open by Lord Hoffman and supported by Lord Browne-Wilkinson and Lord Lloyd. It is necessary therefore to examine the statutory options in the light of our consultation on Discussion Papers Nos 95 and 99.

(3) Possible statutory safeguards

We have identified four possible options in the formulation of statutory safeguards against reopening settled payment transactions following on a judicial decision changing a settled view of the law. These are:

(i) prospective overruling;

(ii) shortening the five year period of negative prescription;

(iii) introducing a statutory safeguard barring recovery of all payments made before the decision without exceptions; and

(iv) introducing such a statutory safeguard subject to exceptions.

We consider these options in that sequence.

(4) First possible option: prospective overruling

2.28

In Scot Law Com DP No 95, we rejected the possibility that a safeguard against opening settled transactions might take the form of a statute enabling the court to declare that a judicial precedent is overruled only prospectively.

(5) Second possible option: shortening the period of the short negative prescription?

Although we have not consulted on it, another possible way of protecting the security of receipts would be to amend the Prescription and Limitation (Scotland) Act 1973

Scots law: prescriptive period runs from date of payment. By contrast, in Scots law, under the 1973 Act, the five year period of the negative prescription of an obligation of repetition of an undue payment begins to run on the date when the recipient is enriched

The result is that a statutory or common law safeguard against reopening settled payment transactions is much less necessary in Scotland than it is in England.

2.33

We do not think that the case has been made out for shortening the five year period of negative prescription of obligations to repay undue payments made under error of law. It would be wrong to reintroduce in an important context the anomalous and sometimes unworkable distinction between errors of fact and errors of law which the Morgan Guaranty case abolished. In that case, Lord Clyde said that the five year prescriptive period gave adequate protection against reopening transactions.

(6) Third possible option: statutory "settled view" safeguard without exceptions

In our Discussion Paper No 99, we said that a "settled view" safeguard against reopening closed transactions is not based on principle or equity but rather on the policy of protecting security of receipts.

^[112]

^[113]

Several commentators on our earlier Discussion Paper No 95 have misgivings about the concept of "common understanding". The Court of Session judges, for example, remarked that there may be a common understanding of the law which has been identified by legal advisers as a misunderstanding and argued that the concept of "common understanding" does not provide the appropriate criterion, departure from which may be taken as in some sense an error. In separate comments, Lord Coulsfield remarked:

"At any given time, there are some areas of the law which can be regarded as reasonably fixed and others which cannot be so regarded, and the degree of uncertainty in the latter areas varies infinitely. How would the paper's proposed solution apply to a case in which 60% of lawyers if consulted would have given an opinion one way and 40% the other? Or if the proportions were 70%/30%? If you are not careful, you may end up with a solution which makes the possibility of recovery depend on the quality of advice available to the person affected, either at the time of the transaction or the time when the possible error is noticed…. If some basis of this kind were to be taken, it seems to me that it would be better to say "a view of the law reasonably held at the time", but that would be not more than a minor improvement."

2.36

The Faculty of Advocates drew attention to certain practical difficulties. They observed that in practice, the payee would presumably have to establish that solicitors and counsel advising clients at the time of payment had had a common understanding. If the state of the law had been an open or controversial question then the defence would fail. The Faculty and another commentator remarked that "landmark" decisions changing the law

^[114]

(7) Fourth option: statutory "settled view" safeguard subject to exceptions

It is possible that a "settled view" safeguard against reopening closed transactions would be more acceptable if appropriate exceptions were made to it. For example, arguably, a person who makes a payment on the faith of a settled view of the law and subsequently raises a successful action overturning the settled view (the payer-challenger) has a specially strong claim to be allowed to recover for three reasons. First, otherwise in many cases persons making payments under error of law would have no incentive to challenge the mistaken settled view of the law.

^[115]

^[116]

For these reasons, in our Discussion Paper No 95, we sought views on a provisional proposal that the payer-challenger should recover.

^[117]

"The person who challenges the mistake may simply be the person who has the funds to take a risk which others cannot afford to take, or the person who happens to consult a legal adviser who is prepared 'to have a go' as opposed to the adviser who may reasonably be regarded as more prudent".

He argued that if there were to be a remedy for error of law, the approach of the British Columbia Commission^[118] was the correct one so that everyone affected by the error should recover if the error were excusable.^[119]

Moreover, it would sometimes be difficult in practice to confine the exception to the payer-challenger. Although Scottish court procedure does not as yet allow "class" or "multi-party" actions,

^[120]

In our Discussion Paper No 95, we also sought views on a second possible exception allowing recovery by any other person who had made a payment under the same error and claimed repayment in an action commenced before the date of the judicial decision in the payer-challenger's action.

^[121]

Blaizot

^[122]

On the other hand, since the policy underlying the safeguard is finality in a wider circle of payment transactions, the safeguard would only work well if the exceptions did not apply to such a circle. Cases falling within the exceptions should not be so numerous as to render the safeguard ineffective. On consultation, the Convention of Scottish Local Authorities (COSLA) and the Society of Directors of Administration in Scotland (SODAT) commented that the exceptions to the bar to recovery could be open to exploitation or abuse. Thus SODAT observed that where a test case was being taken it would be relatively easy for the person promoting the test case to advise persons in a similar position to start proceedings prior to the decision in the test case. They referred to a case where the Police Federation and the Fire Fighters Union advised their members to lodge claims with industrial tribunals in advance of the decision of the European Court in the Coloroll case.

^[123]

^[124]

If however the safeguard were to be enacted without the exceptions, the scope of the abolition of the error of law rule would be very narrow. The only payers who would be entitled to recover would be those whose error was not linked to a subsequent change in a settled view of the law. While such cases do occur,

^[125]

^[126]

^[127]

(8) Consultation

In Discussion Paper No 99 we suggested that the case for a statutory safeguard, with or without exceptions, (the third and fourth options respectively) was not sufficiently strong to justify the intervention of statute. On consultation on that paper, most of those who commented agreed with this view.

^[134]

^[135]

"in cases concerned with overpaid taxes, a case can be made in favour of a principle that payments made in accordance with a prevailing practice, or indeed under a settled understanding of the law, should be irrecoverable. If such a situation should arise with regard to overpayment of tax, it is possible that a large number of taxpayers may be affected; there is an element of public interest which may mitigate against repayment of tax paid in such circumstances; and, since ex hypothesis all citizens will have been treated alike, exclusion of recovery on public policy grounds may be more readily justifiable". (emphasis added)

This was against the background of the existence in English law of a separate and distinct restitutionary regime for taxes and other similar charges which when exacted ultra vires, are recoverable as of right at common law under the principle in the Woolwich case^[136] as well as statutory regimes on refunds.^[137] By contrast, as we have seen, the court in Morgan Guaranty though the Woolwich case showed that the public interest in finality of transactions should not outweigh the interest of private individuals in recovering undue payments.^[138] So far as common law claims are concerned, consultation did not reveal widespread support for giving public authorities a special defence not available to private citizens and bodies.

(9) Conclusions and recommendation

To put our views on the settled view safeguard in context, we summarise our general conclusions on safeguards against reopening settled payment transactions as follows.

(a) Since in legal theory the courts declare what the law is and always was and do not change the law, undue payments made on the faith of, or in accordance with, a settled view of the law later changed by a judicial decision will be treated as made under error and therefore are in principle recoverable under the law of unjustified enrichment subject to the normal defences to a claim based on redress of unjustified enrichment including change of position.^[139] In Scotland there is authority to the effect that the specific ground is error^[140] though the claim may possibly be based on a broader ground.^[141]

(b) The decisions and dicta in the Morgan Guaranty and Kleinwort Benson cases make it extremely unlikely that the Scottish courts would introduce at common law a safeguard against reopening payment transactions following a judicial decision overturning a settled view of the law because such a safeguard could not be founded upon principle and equity but only on policy considerations.^[142]

(c) Therefore such a safeguard could only be introduced by statute.

(d) There is no support for a safeguard in the form of prospective overruling (the first option).^[143]

(e) The five year period of negative prescription provides a reasonable safeguard against the reopening of long settled payment transactions and need not be shortened (the second option).^[144] Since the period of negative prescription begins to run on the date of the payment or enrichment itself rather than (as in England) on the later date of the judicial decision changing the law, no amendment of the Prescription and Limitation (Scotland) Act 1973 comparable to that suggested for the English Limitation Act 1980 is necessary.^[145]

In summary, a statutory "settled view" safeguard with or without exceptions (the third and fourth options) should not be introduced in common law claims for the following reasons.

(i) Such a safeguard would create anomalous distinctions barely intelligible to most laymen who would not understand how they could arise out of principles of unjustified enrichment.^[146] In particular a layman would find it very difficult to understand why if an obligation to pay had always been invalid, he was nevertheless under no error in assuming it to be valid when making the payment (with the result that he could not recover it).

(ii) In principle, the right of a payer to recover on the ground of error should not turn upon what other people might have thought was the law at the time of his payment but upon what he thought was the law at that time. If his view of the law is overturned by judicial decision, it has turned out to have been wrong, however many lawyers might have agreed with him at the time. So there ought to be a remedy in all cases or none.^[147]

(iii) A payment based on a "settled view of the law" is more likely to be excusable than a payment under an error of law entertained by only one payer. It would be highly anomalous if the former error barred recovery which the latter error did not.^[148]

(iv) Following abolition of the error of law rule there is no equitable way of restricting the ambit of recovery to a particular payer or classes of payer. Thus as a minimum the payer-challenger should recover since it would be most unjust if his success in challenging the settled view benefited others but did not benefit him. Yet he may simply be the person who has the funds to take a risk which others cannot afford to take, or the person who happens to consult a legal adviser who is prepared 'to have a go' as opposed to the adviser who may reasonably be regarded as more prudent.^[149] A further exception allowing recovery by persons commencing proceedings before the decision in the payer-challenger's action would mean that organisations with multiple debtors could be faced with co-ordinated action exploiting or abusing any exceptions to the safeguard.^[150]

(v) Since the provisions of the 1973 Act on the short (five years) negative prescription are satisfactory, a statutory or common law safeguard against reopening settled payment transactions is less necessary in Scotland than it is in England.

(vi) It is an anomalous feature of the "settled view" safeguard that the longer ago the payment was made, the less likely is it to have been made under a settled understanding of the law. The negative prescription produces a more just result than would a "settled view" safeguard.^[151]

(vii) The concept of a "settled view of the law" is likely to be unacceptably uncertain, causing difficulties of proof and expensive litigation with an unpredictable outcome. In this respect it compares unfavourably with the relative clarity and certainty of the rules on negative prescription.

(viii) In other legal systems where the error of law rule has been abolished by judicial decision,^[152] no "settled view" safeguard has as yet proved necessary.

For reasons such as these, the "settled view" safeguard has been rightly described as incapable of precise definition, lacking in principle and productive of unacceptable anomalies and unpredictable absurdities.^[153]

We recommend:

Where payments are made on the faith of a settled view of the law to the effect that the payments are due, and that view is later changed by a subsequent judicial decision, recovery of the payments should not be barred by statute but should continue to be regulated by the common law (under which the payments will be recoverable unless the court finds that it would be inequitable to order repayment).

"A person may be said to have received unjustified enrichment at another's expense when he has obtained a benefit from his actings or expenditure, without there being a legal ground which would justify him in retaining that benefit, and it is in accordance with equity that he should account for that enrichment".^[176]

Again in Shilliday v Smith,^[177] Lord Caplan remarked:

"The simple equitable formulation of the rules arising from unjust enrichment would perhaps be: 'Is it right that a person should be entitled to retain a valuable benefit in circumstances where the person who conferred it had no intention that he should keep it?'"

New ground of repetition limited to public sector debts or bodies?

We believe that, as a matter of principle and policy, there is a virtually unanswerable case for giving the citizen a remedy on the Woolwich facts. To that extent, the decision of the House of Lords in the Woolwich case is to be welcomed. The difficulty we have however lies in accepting that the introduction of a new ground of repetition limited to public sector debts or bodies (however defined) provides the best path to reform.

2.58

In the Woolwich case, Lord Goff said that one objection to this decision:

"is to be found in the structure of our law of restitution, as it developed during the 19th and early 20th centuries. That law might have developed so as to recognise a condictio indebiti - an action for the recovery of money on the ground that it was not due. But it did not do so. Instead, …there developed common law actions for the recovery of money paid under a mistake of fact, and under certain forms of compulsion. What is now being sought is, in a sense, a reversal of that development in a particular type of case; …".^[178] (emphasis added)

The last words are important since they, together with other dicta,^[179] show that English law is still committed to a system of very specific grounds of restitution.

The Woolwich case gave little guidance as to the type of public debts to which the new ground of recovery should apply and there is considerable uncertainty as to what the criterion of scope should be.

^[180]

Woolwich

This however is exceedingly difficult to accomplish. At least nine justifications were mentioned in the Woolwich case itself

^[181]

^[182]

^[183]

Woolwich

First, many of the justifications could be invoked as a reason for introducing a rule of automatic recovery applying to private sector debts as well as to public sector debts.

^[184]

Second, there are other justifications which apply well enough to powerful governmental bodies such as the defendant in Woolwich (the Inland Revenue, the epitome of government power in its relations with citizens) but which seem inapt or unconvincing when applied to less powerful public or semi-public bodies (such as privatised trust ports) and appear especially inapt and even absurd when applied to a small private trader (such as a statutorily licensed taxi-cab operator with one cab).

^[185]

Third, the only remaining justification is the public law principle of legality.

^[186]

Woolwich

In our Discussion Paper No 100, Part IV, we sought views on whether the Woolwich rule should be introduced in Scots law by statute. The general reaction was against statutory intervention on this matter. We concur in that view.

2.65

We therefore recommend:

It is unnecessary to introduce the Woolwich rule (under which a citizen who makes an undue payment of tax or similar levy to a public authority pursuant to an ultra vires demand has a prima facie right to repayment) into Scotland by statute since in comparable circumstances the Scottish courts would give a citizen a remedy by reference to the principles of Scots law.

(Recommendation 2)

Part 3 The Statutory Provisions for Refund of Overpaid Tax or Rates

A. INTRODUCTORY

In our Discussion Paper No 100, we sought the views of Scottish consultees on provisional proposals for Scotland parallel to the recommendations made by the Law Commission in Parts IX to XV of their Report on Restitution: Mistakes of Law and Ultra Vires Public Authority Receipts and Payments (1994) Law Com No 227, which, at that time, we generally supported. The stated aim of the recommendations in these Parts was to incorporate "the Woolwich rule"

^[187]

^[188]

1. Types of tax and levy covered by the Law Commission's recommendations

In Law Com No 227, the Law Commission considered the following types of tax or levy:-

* Taxes administered by the Inland Revenue (Income Tax; Inheritance Tax; Stamp Duties);

* Indirect Taxes (Value Added Tax; Charges governed by European Law; Excise Duties and Car Tax; Insurance Premium Tax);

* National Insurance Contributions;

* Local Authority Council Tax.

From the standpoint of Scots law, it is necessary to add:

* Local Authority Non-domestic Rates and Water Rates due under statutes applying only in Scotland.

Overview

3.4

Recommendations in Law Com No 227. In respect of ultra vires receipts by public authorities, the English Law Commission stated that there should be a series of specific amendments to the provisions for refund of overpaid tax in legislation governing the principal central and local government taxes, to reflect the emergence of the Woolwich principle, the proposed abolition of the mistake of law bar

Developments since 1996. Since our Discussion Paper No 100 was issued in 1996, several significant events have occurred which alter the balance of the argument. First, FA 1997 has strengthened the defences available to the Board of Customs and Excise against claims for refunds of VAT. Among other things, FA 1997, s 47, abolished the "due diligence" formula regulating the commencement of the limitation period for claims for refunds for VAT

Refund of rates under LG(FP)(S)A 1963, s 20(1). The only type of tax discussed in this Part which differs in its machinery of collection and refund from the English law is non-domestic rates.

^[199]

^[200]

More difficult is the question whether it is reasonable to regard the statutory machinery for appeals against valuation notices and demand notes for rates, rather than the application for refund under the LG(FP)(S)A 1963, s 20(1), as the main safeguard for ratepayers against overpayments of rates. It would be pointless for legislation to provide time limits for appeals if these time limits can simply be ignored by a ratepayer and application made by him instead for a refund under the 1963 Act, s 20(1). So the main question is what is the proper role of the 1963 Act, s 20(1)? There is a choice. Should it be considered (following Law Com No 227 and our Discussion Paper No 100) as equivalent to the Woolwich rule with the result that it should provide for refund of an undue payment made pursuant to an ultra vires demand irrespective of any error of fact or law on the part of the ratepayer? Or should it be regarded rather in its statutory context as a longstop provision making a closely defined exception to the principle of the finality of the valuation and assessment rolls and so applying only where the undue payment was made under error of fact or law and not otherwise? We turn now to consider the provision in its statutory context.

B. NON-DOMESTIC RATES

1. The existing law

(1) The statutory scheme for fixing liability to non-domestic rates

3.8

Valuation and assessment rolls. The system of valuation and rating

(a) Valuation roll

The valuation roll and the limitation of rating to non-domestic subjects. The Local Government (Scotland) Act 1975, section 7 provides that every rate levied by a rating authority

^[206]

^[207]

Under the 1975 Act as originally enacted, domestic dwellings were included among the subjects entered in the valuation roll, since their occupiers were assessed for rates. The Abolition of Domestic Rates Etc. (Scotland) Act 1987 introduced the community charge and (as its name implies) abolished domestic rates with effect from 1 April 1989.

^[208]

^[209]

The 1987 Act was repealed by the LGFA 1992, which replaced the community charge with the council tax.

Statutory applications and appeals concerning entries in valuation roll. Statutory provisions lay down special procedures for dealing with appeals or complaints concerning entries in the valuation roll, namely, application to the assessor for redress;

Finality of valuation roll. As a general rule, the valuation roll, when completed by the assessor and placed in the hands of the rating authority as the basis for levying assessments,

(b) Assessment roll

Finality of assessment roll. Liability for rates is directly determined not by the valuation roll but by the assessment roll,

There are two statutory qualifications to the conclusiveness of the assessment roll. (i) Within a year after the end of the year of assessment, the rating authority may amend the assessment roll by striking out a person's name on an assessor's certificate or by correcting the amount of any value or rate which may have been inaccurately entered.

^[235]

^[236]

^[237]

Demand note for rates and appeals to rating authority. Every rating authority has a duty "as soon as practicable" to issue demand notes, for payment of rates payable to the authority, to every person liable.

(2) General statutory right of recovery under LG(FP)(S)A 1963, section 20(1)

The Local Government (Financial Provisions) (Scotland) Act 1963, section 20(1) provides:

"Where, notwithstanding section 2(2)(d) of the Local Government (Scotland) Act 1975 or any entry in a valuation roll which is no longer in force,^[243] it is shown to the satisfaction of a rating authority that any amount has been paid to them in respect of rates by reason of an error of fact, and the amount is not recoverable apart from this section, the authority shall repay the amount to the person from whom they received it or to any other person appearing to them to be entitled to that person's interest:

Provided that no repayment under this subsection shall be made after the end of the sixth year after that in respect of which the amount was paid, unless application therefor was [made] before that time." (italics added)

The provision will prevail over the 1975 Act, section 2(2)(d), in a conflict between them. This means that if an erroneous entry made in year 1 is not discovered till year 8, the ratepayer may recover under the 1963 Act, section 20, overpayments made in the last 6 years whereas the assessor under the 1975 Act, section 2(2)(d), can only correct the error with effect from the beginning of year 8.

The aim of LG(FP)(S)A 1963, section 20(1). Light is cast on the aim of the section by the Notes on Clauses.

^[244]

"no general provision in the Local Government Acts for the repayment of rates overpaid over a period of years. Once the Valuation Roll has been closed and appeals against entries disposed of, it is not possible to re-open it; and as far as the Assessment Roll is concerned, that is, the roll from which the rates are levied, there is no power to remit rates except in the current and immediately succeeding financial year.^[245]"

The 6-year time-limit derived by analogy from the Income Tax Acts and the corresponding English rates provision, now repealed.

^[246]

The scope and meaning of "error" in LG(FP)(S)A 1963, section 20(1). The main defect in section 20(1) is that it only applies to error of fact, not at all to error of law. But there are other difficulties. Section 20(1) makes it clear that the error must have caused the payment.

^[247]

In principle, it might be thought that the first approach would be followed because the British Railways Board case

^[248]

First, the 1963 Act, section 20, allows recovery of the amount overpaid only if it "is not recoverable apart from this section", eg at common law. In a common law action for repetition of an overpayment caused by an error in the valuation roll or assessment roll, generally the amount will not be recoverable (because of the local authority's defence of failure to exhaust statutory remedies).

^[249]

Second, the Notes on Clauses indicate that the section was intended to cover cases where (a) a person had paid someone else's rates, eg where a man paid his neighbour's rates as well as his own; or (b) the rate levied was not in accordance with the valuation roll; or (c) it emerged on a subsequent revaluation that a particular house had obviously been incorrectly valued by a considerable amount.

^[250]

It is possible that section 20 may also have been intended to apply to an overpayment caused by an error of fact arising after the demand note has become final (eg inadvertent double payment) but such an overpayment would normally be recoverable apart from the section by common law action.

3.25

Defences. The 1963 Act, section 20(1) provides no defences other than the six-year limitation period. The requirement that the amount claimed be "not recoverable apart from this section" means that common law defences can be elided by recourse to the section. This is no doubt justifiable in some cases

^[251]

2. Recommendations for reform

(1) Reform of ground of claim

Since the rating authority's duty to repay under section 20(1) of the 1963 Act arises only where the reason for the ratepayer's payment was an error of fact, it is clearly now out-of-date having regard (i) to the abolition of the old common law error of law rule by the Morgan Guaranty case,

ultra vires

This provisional proposal was generally approved by those consultees who commented, with the very important exception of the Convention of Scottish Local Authorities who said that, in the view of experienced practitioners, the existing system functions well and does not need to be changed.

3.28

Our proposal accorded with the general policy in Discussion Paper 100 of widening the grounds of the statutory provisions on refunds beyond error to all undue payments, whether made under compulsion, or pursuant to an ultra vires demand or otherwise. The underlying belief was that the main statutory provisions on refunds (notably TMA 1970, s 33; VATA 1994, s 80; and LG(FP)(S)A 1963, s 20(1)) should include all undue payments so as to be as wide as the post-Woolwich and post-Morgan Guaranty common law grounds of recovery.

ultra vires

On consultation the Law Society of Scotland commented that an error of law may not be unusual in rates cases.

^[259]

^[260]

We recommend:

The ground of a claim for a refund of overpaid rates under section 20(1) of the Local Government (Financial Provisions) (Scotland) Act 1963 (which currently applies only to undue payments made under error of fact) should be extended to cover also undue payments made under error of law, or error of mixed fact and law, but should not be extended to cover payments made without error but under compulsion, or pursuant to an ultra vires demand or otherwise.

(Recommendation 3; Draft clause)

(2) Introduction or amendment of "defences"

3.32

The extension of the ground of claims under the 1963 Act, section 20(1) to refund of rates paid under error of law would increase the importance of defences to such claims. We consider that the widening of the ground should be matched by the introduction of appropriate defences.

(a) Retention of six-years time-limit on application for refund

3.33

Under the proviso to section 20(1) of the 1963 Act, no statutory refund may be made after the end of the sixth year after that in respect of which the amount was paid, unless application therefor was made before that time. We sought views on three possible modifications of this time limit.

^[261]

Limitation rather than prescription. The first was whether the period should be one of negative prescription or a simple statutory limitation period. There is a technical reason for preferring a limitation period. A period of negative prescription may be extended by interruption of the prescriptive period.

^[262]

Duration of limitation period. Secondly, as regards the length of the period, the six years limitation period was introduced in 1963 long before the introduction of the five-year negative prescription in 1973. The time limit on claims for refund of overpaid income tax and capital gains tax under TMA 1970, section 33 is now five years after 31st January next following the year of assessment to which the return relates.

^[263]

^[264]

It is true that COSLA agreed to the retention of the six years time limit against the background of our provisional proposal that a defence of payment in accordance with a "settled view" of the law would be available to a rating authority in a claim under the 1963 Act, s 20(1) and that we do not now recommend the introduction of that defence.

^[265]

^[266]

Assessing this very difficult topic as best we can, we think that six years is a reasonable period. We state below

^[267]

Commencement of limitation period. Thirdly, under the present law, the six year period begins to run at the end of the year in respect of which the amount of rates in question was paid. In our Discussion Paper we suggested that in a claim based on error, time should not begin to run against the ratepayer until he discovers the error or could with reasonable diligence have discovered it.

^[268]

^[269]

We recommend:

The rule laid down by the proviso to section 20(1) of the Local Government (Financial Provisions) (Scotland) Act 1963 (under which no refund under that section may be made after the end of the sixth year after that in respect of which the amount was paid, unless application therefor was made before that time) should be retained.

(Recommendation 4; Draft clause)

(b) Res judicata and compromises

3.40

The 1963 Act, section 20(1) makes no reference to the defences of res judicata and compromise. These defences are respectively designed to promote the public interest in the finality of litigation and in agreements freely entered into to avoid litigation. They both depend on the principle that a person should not be vexed twice for the same cause. Section 20(1) provides that the amount claimed must be "not recoverable apart from this section", for reasons which are not clear. Since these defences would make the amount not recoverable in a common law action, it appears that they would not prevent a section 20(1) claim. This seems contrary to principle and unreasonable.

3.41

Res judicata. The defence of res judicata is available where the question in an action has already been decided between the parties.

^[270]

res judicata

^[271]

foro

absolvitor

^[272]

^[273]

^[274]

Compromise. The 1975 Act provides that where at any time before an appeal or complaint against an entry in the valuation roll is determined by a valuation appeal committee or the Lands Tribunal for Scotland, the parties reach agreement as to what should be done about the entry, the assessor may alter the roll to give effect to the agreement.

^[275]

^[276]

A compromise relating to a disputed debt has the effect of discharging that debt and of creating a new independent obligation of payment which replaces that debt.

Recommendation. In our Discussion Paper No 100, we suggested that the defences of res judicata and compromise should be expressly recognised by statute as available to a local rating authority in a claim under section 20(1).

^[282]

We recommend:

A statutory claim under section 20(1) of the Local Government (Financial Provisions) (Scotland) Act 1963 for recovery of an undue payment of rates should not lie where:

(a) a claim for the rates in question had been contractually compromised; or

(b) the payment was made in response to a court action by the rating authority against the ratepayer in circumstances which would raise a plea of res judicata against the ratepayer in an action by him against the authority for repetition.

(Recommendation 5; Draft clause)

(c) Unjust enrichment of claimant or "passing on"

3.46

The Law Commission recommended that it should be a defence to claims for the repayment of taxes overpaid as a result of mistake that repayment would unjustly enrich the claimant.

^[283]

"where the burden of a charge has effectively been 'passed on' to other parties by the charge payer through an increase in the price of goods or services to take account of the higher cost to the payer arising from the payment of the charge."^[284]

A defence of "passing on" is one form of a defence that the payer would be "unjustly enriched" by repayment.^[285]

Existing law. A leading Scottish text-book suggests that in considering whether to grant repetition of an undue payment of money at common law, the court may consider whether the pursuer has passed on the payment in charges to his customers

Consultation and conclusion. In our Discussion Paper No 100, we considered this defence in the context of claims for overpaid income tax and rates.

(d) Payment in accordance with a "settled view" of the law or "prevailing practice"

Defence of "payment in accordance with settled view of the law". The extension of section 20(1) of the LG(FP)(S)A 1963 to require the refund of payments of rates made under error of law raises sharply the question whether it should be a defence to such a claim that the payment had been made by the ratepayer in accordance with a "settled view of the law that the payment was due", and a later judicial decision has overturned that view. This matter was fully discussed in Part 2 above in connection with the formulation of defences or safeguards against common law actions of repetition following on a judicial decision changing a settled view of the law.

^[305]

^[306]

"Generally prevailing practice". In the case of income tax, Parliament has already recognised that public finances should be protected against opening floodgates by enacting the "generally prevailing practice" defence in TMA 1970, section 33(2),

^[307]

^[308]

Consultation. On consultation, there were mixed views on whether "payment in accordance with a settled view of the law" should form a defence or exception to an application for refund of overpaid rates.

^[309]

^[310]

On the other hand, the Royal Institute of Chartered Surveyors in Scotland said that an overpayment of rates under error of law should be recoverable provided that back dating was restricted to the start date of the relevant quinquennial revaluation cycle. The Scottish Chamber of Commerce took a similar view. The Law Society of Scotland sounded a note of caution. They considered that in practice the distinction between a change in the settled view of the law and an error of law may be difficult to draw. They thought that the point required further clarification.

3.55

Policy considerations. In the light of consultation, we were inclined at first to recommend the introduction of the "settled view" defence in claims under the 1963 Act, s 20(1). However, the criticisms made of the proposed "settled view" defence or safeguard by the majority of the judges in the House of Lords in the Kleinwort Benson case

"Generally prevailing practice" defence. A "generally prevailing practice" defence

^[315]

If (contrary to our recommendations) it is considered that a further defence or safeguard against opening the floodgates to too many section 20(1) claims is required, a shortening of the six year time limit for claims based on error of law, or mixed error of fact and law, would in our view be preferable to the introduction of either a "settled view of the law "defence or a "generally prevailing practice" defence.

^[316]

To sum up, we make no recommendation to introduce the following defences to a claim under the 1963 Act, section 20(1), namely that the payment by way of rates was (a) made by the ratepayer in accordance with a settled view of the law that the payment was due, and a later judicial decision has overturned that view, or (b) charged in accordance with the practice generally prevailing at the time when the payment was demanded.

(e) Non-exhaustion of statutory remedies

3.59

The existing law on the defence of non-exhaustion of statutory remedies. Where a ratepayer challenges an entry in the valuation roll, his failure to use or insist in the statutory avenue of appeal against an assessor's acts amending the valuation roll will bar a common law remedy

^[317]

^[318]

As regards a ratepayer's challenge against rating, it used to be thought

^[329]

"may appear as a general statement, when Parliament has enacted that there is to be a right of appeal and designates the body which will hear that appeal, no matter who or what the body is, then it is a statutory appeal".^[330]

Accordingly it did not matter that the statutory avenue of appeal was to the rating authority which was also the authority which had made the allegedly ultra vires demand and received the payment.

It is not for us to recommend changes to appeals against rating. We cannot however completely ignore the fact that a local authority entertaining an appeal against a rates demand note are indeed judges in their own cause

^[331]

^[332]

In the British Railways Board case,

^[333]

"that recourse to common law proceedings in the Court of Session is not competent if the complainer has not availed himself of his statutory right of review, unless the failure was due to ignorance owing to some irregularity of procedure on the part of the assessor or rating authority, to the fact that resort to the statutory remedy would in the particular circumstances be otiose or to some other special reason".^[334]

Proposal in DP 100 to introduce defence. However the defence of non-exhaustion of statutory remedies is not available to a rating authority in a claim under the 1963 Act, section 20(1) for refund of overpaid rates. That provision allows a claim for refund long after the time-limits have expired for exercising statutory rights of appeal.

^[335]

^[336]

Defence of non-exhaustion unnecessary if error ground of refund. We now recommend however that error of some kind should remain an essential requirement of obtaining a refund of overpaid rates under the 1963 Act, section 20(1), albeit the error could be of law or fact.

^[337]

^[338]

Recommendation: certain defences not to be introduced

We recommend:

In a claim for refund of overpaid rates under section 20(1) of the Local Government (Financial Provisions) (Scotland) Act 1963, it should not be a defence:

(a) that the refund would unjustly enrich the claimant;

(b) that the undue payment of rates was made in accordance with

(i) a settled view of the law that the payment was due; or

(ii) with a generally prevailing practice,

and a later judicial decision has overturned that view or practice; or

(c) that the claimant has not exhausted his statutory remedies, including appeals against valuation or rating notices.

(Recommendation 6)

C. TAXES ADMINISTERED BY THE INLAND REVENUE

1. Income Tax, Corporation Tax, Capital Gains Tax and Petroleum Revenue Tax

(1) The Law Commission's recommendations

3.66

In the domain of income tax and certain other direct taxes administered by the Inland Revenue, the main statutory provision for refund of overpaid tax is TMA 1970, section 33 which provides:

"33.-(1) If any person who has paid tax charged under an assessment alleges that the assessment was excessive by reason of some error or mistake in a return, he may by notice in writing at any time not later than six years after the end of the year of assessment (or, if the assessment is to corporation tax, the end of the accounting period) in which the assessment was made, make a claim to the Board for relief.

(2) On receiving the claim the Board shall inquire into the matter and shall, subject to the provisions of this section, give by way of repayment such relief in respect of the error or mistake as is reasonable and just: provided that no relief shall be given under this section in respect of an error or mistake as to the basis on which the liability of the claimant ought to have been computed where the return was in fact made on the basis of or in accordance with the practice generally prevailing at the time when the return was made."

3.67

The Law Commission criticised TMA 1970, section 33, mainly because its scope is narrower than the Woolwich rule. They observed that "there are situations where a taxpayer would have a right under the Woolwich principle to repayment of tax demanded ultra vires which would be denied under section 33."

^[339]

^[340]

^[341]

"There are situations where the section 33 right applies, but relief would be denied under the section whereas it would be permitted under the Woolwich principle. The House of Lords in Woolwich indicated that where a taxpayer had a statutory right of recovery, this should be pursued and was exhaustive of his rights. However, we believe it to be unfair to the taxpayer that he should have narrower rights where statute has addressed the issue than in those cases where it has not, unless there is a good reason for this difference."^[342]

The Law Commission therefore recommended:

"a repeal of TMA 1970, section 33 and replacement by a right on the part of all taxpayers charged to tax, whether under an assessment or otherwise, to recover tax paid but not due irrespective of the presence or absence of any mistake on the part of the taxpayer".^[343]

The Law Commission further recommended that the right to repayment should be subject to the following defences:

^[344]

^[345]

(2) Our Discussion Paper and consultation

In our Discussion Paper No 100, we invited views, primarily from Scottish interests, on the Law Commission's recommendations.

^[346]

^[347]

Secondly, while we agreed with the Law Commission that it should be a defence to a statutory claim for recovery of an overpayment of tax that a claim for the tax in question was contractually compromised,

^[348]

^[349]

res judicata

^[350]

On consultation, though our provisional proposals met with general acceptance, the Inland Revenue made fundamental criticisms which have led us to depart from those proposals.

(3) The self-assessment system

3.73

The Law Commission's arguments were primarily directed towards the system of assessment in force before the taxation year 1996-1997 and were then extended to self-assessment,

^[351]

^[352]

^[353]

Under that system, it is the taxpayers themselves who create the legal charge to tax by making a self-assessment of their liability to income tax and capital gains tax for any year. The return which taxpayers are required to complete is a return of all the information needed to calculate their total taxable income from all sources and any chargeable gains for the period covered by the return. The responsibility for creating the correct legal charge is therefore on the taxpayer who can either calculate the tax due on the return form or leave the arithmetical calculation to the Inland Revenue. In either case the assessment is a self-assessment and is not open to appeal. If the taxpayer fails to file a return an Inland Revenue officer may make a determination of the tax due by the taxpayer.

^[354]

"Repair" or amendment of return. On receipt of a return the Revenue's initial processing involves only the calculation of the tax due using the figures in the return (where that has not been done by the taxpayer) and the correction of any obvious errors. This is "repair" of a return and involves replacing an incorrect calculation based on the information provided by the taxpayer with a correct calculation based on that same information. Where a taxpayer disagrees with a "repair" he can amend the return back to its original state (unless it is under enquiry). In such a case the Revenue's only recourse is to open a formal enquiry into the return.

3.76

Claim for refund under TMA 1970, s 33. The Inland Revenue has nine months from the delivery of a return in which to "repair" it and a taxpayer has twelve months from the filing date in which he may amend his self-assessment.

Processing of taxpayer's return. The normal processing of a taxpayer's return goes forward on the basis that the information provided in the return is accurate. It is, however, open to the Inland Revenue to enquire into any return provided it does so within the statutory time limit.

The only assessments which are issued by the Revenue in self-assessment cases are "discovery" assessments

Safeguards for taxpayer against erroneous levies of tax. In summary, the Inland Revenue pointed to four safeguards under the self-assessment system against erroneous levies of tax. First, he will be assessed on the basis of the information which he himself has provided and, if he so chooses, in the amount which he himself has calculated as being correct. Second, if he has made an error in his return and an overpayment has resulted he may amend it within twelve months of the filing date. Refund of the overpayment will then be made automatically. Third, if he discovers outwith that period that he has made an error in his return he may make a claim under TMA 1970, section 33, whether the error made by him was one of fact or law and he has a right to appeal against the Inland Revenue's decision on his claim to the Special Commissioners and, in specific circumstances, to the courts.

^[368]

The Revenue conclude that present statutory appeal machinery provides a fair and effective means of finally determining a taxpayer's liability. It is that machinery, and not section 33, which constitutes the primary safeguard against overpaying tax. Severe criticism of TMA 1970, section 33 is unjustified if that section is considered in its context as a closely defined exception to finality in cases of error or mistake.

3.81

The Revenue further contend that this is not an area of the law which, following the Woolwich case,

(4) Our recommendation

In view of these representations by the Inland Revenue, we believe that it would be unrealistic for us to press for legislation on the lines recommended by the Law Commission, for several reasons. First, since Parliament has recently introduced the new self-assessment system by legislation designed to balance the rights of the State and the taxpayer, it would be unrealistic for us to recommend, over the protests of the Inland Revenue, legislative changes significantly altering that balance. Second, there is no separate Scottish dimension. Third, since the Law Commission abandoned their original proposal for imposing uniformity on recovery rights in all the different statutory tax régimes, there is no statutory template with which recovery of Inland Revenue taxes must comply. Fourth, unlike the legislation on recovery of rates in Scotland,

^[375]

2. Inheritance Tax^[376] and Stamp Duty^[377]

The Law Commission recommended that the legislative scheme developed in relation to income tax should apply also to two other Inland Revenue taxes namely inheritance tax

^[378]

^[379]

3. Conclusion

We make no proposal for amendment of the Taxes Management Act 1970, section 33 (which applies to income tax, corporation tax, capital gains tax and petroleum revenue tax) nor for its extension (with or without amendment) to inheritance tax or stamp duty.

D. INDIRECT TAXES ADMINISTERED BY HM CUSTOMS AND EXCISE^[380]

(1) General

The system of collection of value added tax (VAT)

Recovery rights. Section 80(1) of the Value Added Tax Act 1994 (formerly section 24(1) of the Finance Act 1989) provides that where a person has paid an amount to the Customs and Excise Commissioners by way of VAT which was not tax due to them, they shall be liable to repay the amount to him

^[385]

^[386]

Law Commission's recommendations. In Law Com No 227, the English Law Commission recommended no change to the recovery rights under VATA 1994, section 80 for two reasons. First, UK national law has to conform to EC law which recognises only two limits on the right to recovery, namely, the defence of "unjust enrichment" and reasonable limitation periods. Second, the Commissioners of Customs and Excise were satisfied with the operation of VATA 1994, section 80, and they confirmed that the defences recommended for direct Inland Revenue taxes were not needed.

^[387]

Discussion Paper No 100. In our Discussion Paper No 100, we sought views on the Law Commission's recommendation (with which we concurred) that the scheme for recovery of overpaid VAT in the VATA 1994, section 80, should not be altered.

^[388]

Excise duty. The Law Commission also recommended that overpaid excise duties should be subject to the same recovery régime as overpaid VAT.

^[389]

^[390]

(2) Recent legislation amending VATA 1994

Difficulties with VATA. On consultation, Customs and Excise explained to us that it was only after they had lost some high profile court cases that it became clear that VATA 1994, section 80, was unsatisfactory, from the Government's point of view, in two respects, namely the unduly long limitation period for refund claims in mistake cases,

^[391]

^[392]

(a) Reduction of limitation period

Unduly long limitation period in mistake cases. Under section 80 of VATA 1994 as originally enacted, no claim for refund could be made more than six years after the date on which the over-payment of VAT was made,

^[393]

^[394]

As Customs and Excise explained to us, the latter provision meant that once the mistake had been discovered, the taxpayer could make a claim dating back to the beginning of the time when they first began paying the money. In some cases this meant back to 1973, when VAT was introduced. This could result in unforeseeable and unquantifiable burdens on the public purse. The Government could, and did, suddenly find itself liable to make very large refunds for which it had not budgeted. As a result, the general body of taxpayers may have to foot a greater tax bill than the Government intended to enable the exchequer to make repayments to businesses.

3.93

Customs and Excise informed us that some of the Government's identified liabilities to make refunds have been very large

^[395]

^[396]

Finance Act 1997, s 47. To meet this criticism, section 80 of VATA 1994 was amended by section 47 of FA 1997 which provides that the Customs and Excise are not liable, on a claim under section 80 for refund of overpaid VAT, to repay any amount paid to them more than three years before the making of the claim.

^[397]

^[398]

(b) Unjust enrichment of taxpayer or "passing on"^[399]

European Community law. The defence of unjust enrichment stems from European Community law, under which the national law of a member State may provide for a defence of "unjust enrichment" in an action for repayment of a tax, charge or duty levied in breach of Community law.

San Giorgio

Société Comateb & Ors. v Directeur Général des Douanes et Droits Indirects

^[408]

Taxpayer's "unjust enrichment" cancelled out by his loss of profit. As we indicated in Discussion Paper No 100,

Comateb

Comateb

Consultation. In our Discussion Paper No 100 we observed that since apparently the defence works well in VAT and excise duty cases, we did not propose its abolition there.

^[414]

The defence of unjust enrichment only achieves justice if the trader has passed on the illegal VAT to his customer, the ultimate consumer, and his gain thereby acquired is not offset by lost business. For a time traders argued that they rather than their customers bore the VAT because their prices were dictated by competitive market forces rather than by the effect of the VAT. So the overpayment of VAT was financed by cutting into profits rather than by charging increased prices to customers.

Finance Act 1997, section 46. To remedy this mischief, the Finance Act 1997, section 46

^[419]

^[420]

^[421]

Conclusion

Our provisional proposal supporting the Law Commission's recommendation against amending the Value Added Tax Act 1994, section 80, was based on the agreement to that effect which then obtained as between the Law Commission and HM Customs and Excise. That proposal has been overtaken by events, notably the drain on the public purse arising from the operation of section 80 as originally enacted and the consequential amendments of section 80 made by the Finance Act 1997. There is here no separate Scottish private law dimension, nor even any separate Scottish dimension. It is not for us to recommend changes to new provisions so recently passed by Parliament.

Other indirect taxes

3.102

The above changes apply equally to the other indirect taxes administered by Customs ie excise duties and taxes, including air passenger duty, insurance premium tax and landfill tax.

^[422]

^[423]

^[424]

Conclusion on indirect taxes

In these circumstances we make no recommendation for amending the scheme for recovery of overpaid VAT in the Value Added Tax Act 1994, section 80, as amended by the Finance Act 1997.

E. SOCIAL SECURITY CONTRIBUTIONS

3.104

There is a provision in the Social Security (Contributions) Regulations 1979

In our Discussion Paper No 100,

^[430]

^[431]

ultra vires

We understand that there are no present plans to make the amendment recommended by the Law Commission. However we draw the attention of the competent authorities to the fact that the Law Commission's recommendation was approved by Scottish consultees (without specific comment).

F. COUNCIL TAX^[432]

The Local Government Finance Act 1992

As regards claims for refund of overpaid council tax, there is a difference between limitation in England and Wales and negative prescription in Scotland. In England and Wales, a six-year time limit from the date the cause of action accrued is imposed by the general law on recovery under statutes.

^[442]

^[443]

^[444]

In our Discussion Paper No 100, we concurred with the Law Commission's general recommendation^[445] that the existing scheme for the recovery of undue council tax should not be altered. We further agreed with the Law Commission that overpayments demanded ultra vires should be recoverable but did not think it necessary to amend the regulations to achieve that result.^[446] Since these views were generally approved on consultation, we make no proposal for reform of the scheme for the recovery of undue council tax.

**Part 4 Recovery by Public Authorities of Ultra Vires Disbursements**

Preliminary

In this Part, we consider the recovery by public authorities of ultra vires disbursements. Since the topic was considered by the English Law Commission in their Consultation Paper and Report, and relates to the fundamental constitutional principle of the authorisation by Parliament of payments out of the Consolidated Fund, it was necessary to ensure that the law on each side of the border is substantially the same.

^[447]

The existing law

Scots cases. There are remarkably few reported cases of actions by "public authorities" for repetition of ultra vires or undue payments made by them. Most of the cases relate to actions for repayment of parochial relief paid unduly to a pauper under the old poor law.

ultra vires

bona fide

Ultra vires payments out of the Consolidated Fund: the Auckland Harbour Board rule. In the leading case of Auckland Harbour Board v The King,

^[452]

"For it has been a principle of the British Constitution now for more than two centuries, a principle which their Lordships understand to have been inherited in the Constitution of New Zealand with the same stringency, that no money can be taken out of the Consolidated Fund into which the revenues of the State have been paid, excepting under a distinct authorization from Parliament itself. The days are long gone by in which the Crown, or its servants, apart from Parliament, could give such an authorization or ratify an improper payment. Any payment out of the Consolidated Fund made without Parliamentary authority is simply illegal and ultra vires, and may be recovered by the Government if it can, as here, be traced".^[453]

As a principle of the British Constitution, it must presumably apply in Scots law, unless possibly broadly the same result is achieved by reference to wider principles of Scots law. No Scots reported case referring to the principle has been traced.^[454]

In Scots law, on one approach, the Auckland Harbour Board rule could be subsumed within the condictio sine causa.

^[469]

^[470]

On the other hand, we also acknowledged in our discussion paper

^[471]

Auckland Harbour Board

This view was supported on consultation by the few who commented.

^[472]

Auckland Harbour Board

"The control of payments from the Consolidated Fund is control of supply and that is the basis upon which our system of Parliamentary government depends. It is for this reason that the Privy Council pronounced such an apparently absolute rule - though like everyone else, I suspect that the usual restitution defences apply. Subject to that qualification, I do not believe that one can or should downgrade the importance of the principle that moneys cannot be paid out of the Consolidated Fund without authority and that, if they are, they can be recovered. Nor do I think that Parliament would pass such a measure even if it were asked to".

Our consultation revealed that, as in England and Wales, there is insufficiently strong support in Scotland for statutory measures amending the Auckland Harbour Board rule.

In the light of these considerations we recommend:

The Auckland Harbour Board rule (under which ultra vires disbursements by central government from the Consolidated Fund, and possibly other ultra vires disbursements by public authorities from other public funds, are always recoverable) should not be reformed by legislation at the present time.

(Recommendation 7)

Part 5 Future Development of the Law of Unjustified Enrichment

5.1

The Commission has a statutory duty under section 3(1) of the Law Commissions Act 1965 to keep under review the law with a view to its systematic development and reform including its simplification and modernisation. At least until recently, most commentators agreed that the present state of the law of Scotland on unjustified enrichment was unsatisfactory. The law was complex and in some cases obscure. It lacked a concerted jurisprudential theory and drew its principles from a number of disparate sources. Throughout the 1990s we have had in view the possibility of a comprehensive reform of the law of unjustified enrichment.

5.2

In Discussion Paper No 95

^[473]

Morgan Guaranty Trust Company of New York v Lothian Regional Council

^[474]

There remained the second main provisional proposal in Discussion Paper No 95, namely that there should be a statutory safeguard to prevent persons who had paid a purported debt in accordance with a settled view of the law later overturned by a judicial decision from recovering their payment, lest a wide circle of closed transactions be opened up whenever such a decision was made.

^[479]

^[480]

At that time we were proceeding in terms of our Fourth Programme of Law Reform.

^[481]

Fifth Programme of Law Reform

In the event we included the subject in our Fifth Programme with the approval of the Lord Advocate in the following terms:

"2.27 We also think, as a result of our extensive work to date on obligations for the redress of unjustified enrichment, that the topic may be suitable for more comprehensive reform. We propose to undertake this as a long-term project.

2.28 In our Discussion Paper No 95 on Recovery of Benefits Conferred Under Error of Law, we sought views on provisional proposals that the rule precluding recovery of benefits conferred under error of law should be abrogated by statute. This proposal has been superseded by a recent case in which the Court of Session in effect abolished that rule. The decision of the Court made very significant advances in developing the Scots law of unjustified enrichment, but also shows how difficult it is for the courts to reform the deep-rooted structural faults in the present law. There is uncertainty and undue complexity at every level, for example as to the differences between the main obligations or remedies of repetition, restitution and recompense; as to the scope and requirements of the forms of action or claim (condictiones and innominate actions) subsumed under repetition and restitution; and as to the specific grounds which have to be proved to establish a claim.

2.29 These defects remain. In a recent discussion paper, therefore, we invited comments on a proposal to publish a further discussion paper setting out a "non-binding" statement (or "restatement") of the existing law on unjustified enrichment and seeking views on whether comprehensive statutory codification or further piecemeal statutory reforms are desirable. In an appendix, we also published Draft Rules on Unjustified Enrichment and Commentary which had been prepared by Dr E M Clive to test the feasibility of codification. While opinion was divided, there was considerable support for such a discussion paper - hence our present proposal to undertake a further long-term project on the topic, possibly including an exercise in codification."^[482]

"2.28 We have encountered unexpected complexities in finalising the report on diligence on the dependence and admiralty arrestments. Consequently, we have had to concentrate resources on that project. We now intend to publish during 1998 a short report on unjustified enrichment, proposing certain limited reforms. On completion of our work on diligence, we will reassess the need for comprehensive reform of the law of unjustified enrichment in the light of the then state of the law and the pressure, if any, for reform."

In this Report we have confined ourselves to a brief review of limited aspects of unjustified enrichment and to one short but important recommendation for amendment of the law relating to the repayment of overpaid non-domestic rates. We have not attempted a more general review of the subject for the following reasons.

5.10

In the consultation responses to our Discussion Papers Nos 95 and 99 there emerged a strong divergence of view from senior and experienced members of the profession on the questions (a) whether we ought to embark on proposals for a systematic reform of the law on the subject and (b) if we were to do so, in what direction such reform should lie. It became apparent to us that while most commentators recognised that the law might benefit from a systematic overhaul and that it was undesirable that it should remain in its present state, views were nonetheless far from unanimous on the desirability of any particular reform.

5.11

A few consultees favoured codification or comprehensive and systematic legislative reform. One commentator said that the first priority must be to obtain a clear and workable set of rules and that the only real hope of achieving this within a reasonable timescale would be by legislation. Another thought that codification would be a natural development in the civilian tradition of our law.

5.12

On the other hand the majority of commentators opposed codification. Some considered that such a project would be over-ambitious and might create as many problems as it solved.

^[484]

There was more support for a non-binding re-statement. Two commentators observed that the various approaches to unjustified enrichment in current Scottish legal thinking need to be pitted against each other in order that a broad-based consensus may emerge. On the other hand, another consultee said that while the Commission's discussion papers had influenced the development of our law (eg in the Morgan Guaranty

^[485]

We have re-assessed the question of the future development of the law on unjustified enrichment and our involvement in it. In doing so we have taken into account our limited resources and our other priorities.

5.15

We have also taken into account the important decisions of the Inner House of the Court of Session in Shilliday v Smith

^[486]

Dollar Land (Cumbernauld) Ltd v CIN Properties Ltd

^[487]

In the light of these judicial developments we are of the view that our own involvement in this topic should now come to an end, at least for the time being. We have worked extensively on it over the last few years. We have considered options for minor reforms and more radical restructuring. We are pleased that some of our work has already been found useful. Our resources are now needed for other topics.

Part 6 Summary of Recommendations

POSSIBLE AMENDMENTS OF COMMON LAW CONSEQUENTIAL ON MORGAN GUARANTY AND WOOLWICH CASES (PART 2)

Common law claims reopening settled transactions

Where payments are made on the faith of a settled view of the law to the effect that the payments are due, and that view is later changed by a subsequent judicial decision, recovery of the payments should not be barred by statute but should continue to be regulated by the common law (under which the payments will be recoverable unless the court finds that it would be inequitable to order repayment).

(Paragraph 2.49)

The Woolwich rule not to be introduced into Scots law by statute

It is unnecessary to introduce the Woolwich rule (under which a citizen who makes an undue payment of tax or similar levy to a public authority pursuant to an ultra vires demand has a prima facie right to repayment) into Scotland by statute since in comparable circumstances the Scottish courts would give a citizen a remedy by reference to the principles of Scots law.

(Paragraph 2.65)

STATUTORY PROVISIONS FOR REFUND OF OVERPAID RATES (PART 3)

(a) Ground of claim for refund

The ground of a claim for a refund of overpaid rates under section 20(1) of the Local Government (Financial Provisions) (Scotland) Act 1963 (which currently applies only to undue payments made under error of fact) should be extended to cover also undue payments made under error of law, or error of mixed fact and law, but should not be extended to cover payments made without error but under compulsion, or pursuant to an ultra vires demand or otherwise.

(Paragraph 3.31; Draft clause)

(b) Introduction or amendment of "defences"

Time-limit on application for refund

The rule laid down by the proviso to section 20(1) of the Local Government (Financial Provisions) (Scotland) Act 1963 (under which no refund under that section may be made after the end of the sixth year after that in respect of which the amount was paid, unless application therefor was made before that time) should be retained.

(Paragraph 3.39)

Res judicata or compromise

A statutory claim under section 20(1) of the Local Government (Financial Provisions) (Scotland) Act 1963 for recovery of an undue payment of rates should not lie where:

(a) a claim for the rates in question had been contractually compromised; or

(b) the payment was made in response to a court action by the rating authority against the ratepayer in circumstances which would raise a plea of res judicata against the ratepayer in an action by him against the authority for repetition.

(Paragraph 3.45; Draft clause)

Certain defences not to be introduced

In a claim for refund of overpaid rates under section 20(1) of the Local Government (Financial Provisions) (Scotland) Act 1963, it should not be a defence:

(a) that the refund would unjustly enrich the claimant;

(b) that the undue payment of rates was made in accordance with

(i) a settled view of the law that the payment was due; or

(ii) with a generally prevailing practice,

and a later judicial decision has overturned that view or practice; or

(c) that the claimant has not exhausted his statutory remedies, including appeals against valuation or rating notices.

(Paragraph 3.65)

RECOVERY BY PUBLIC AUTHORITIES OF ULTRA VIRES DISBURSEMENTS (PART 4)

The Auckland Harbour Board rule (under which ultra vires disbursements by central government from the Consolidated Fund, and possibly other ultra vires disbursements by public authorities from other public funds, are always recoverable) should not be reformed by legislation at the present time.

(Paragraph 4.11)

Appendix A

Draft Clause

Repayment of rates paid in error.

-(1) For section 20 of the Local ^[488] Government (Financial Provisions) (Scotland) Act 1963 there shall be substituted-

"Repayment of rates paid in error.

20.-(1) Where, notwithstanding-

(a) section 2(2)(d) of the Local^[489] Government (Scotland) Act 1975 (which relates to the date from which corrections of certain kinds of errors in a valuation roll are to have effect); or

(b) any entry in a valuation roll which is no longer in force,

it is shown to the satisfaction of a rating authority, on an application to them in that regard, that an amount has been paid to them in respect of rates by reason of an error, the authority shall, subject to subsection (2) below, repay the amount to the person from whom they received it or to any other person appearing to them to be entitled to that person's interest.

(2) Repayment shall not be made under subsection (1) above if-

(a) in any action for repetition as respects the amount a plea-

(i) of res judicata; or

(ii) that any claim for repetition has been discharged by an agreement of compromise,

would be available to the rating authority; or

(b) the application for repayment is made later than the end of the sixth year after that in respect of which the amount was paid.".

(2) Subsection (1) above does not affect the application of Part II of the said Act of 1963 in respect of any application for repayment which is made, in pursuance of that section, before such day as the Secretary of State may by order appoint.

Explanatory Notes

This clause replaces the existing provisions of section 20 of the 1963 Act. The existing provisions are quoted at para 3.17 of this report. Their aim was to give a citizen a right to a refund of an amount paid by way of rates due to an error of fact. They allow a claim for a refund notwithstanding that the time limits have expired for statutory rights of appeal against entries in the valuation roll or the rates demand notice. For example a claim may be made under section 20 where the rate levied was not in accordance with the valuation roll or a subsequent re-valuation shows that the property had clearly been considerably over-valued.

Subsection (1) of the clause re-enacts section 20 with amendments.

First, the new section 20(1) refers to "error" rather than "error of fact". So a claim for a refund may be made where the error is one of law, or of mixed fact and law, or of fact, whereas under section 20 as originally enacted the error had to be one of fact. This amendment implements recommendation 3 (para 3.31) of the report.

Second, new section 20(2) makes it clear that a ratepayer cannot claim a refund under its provisions if a court action for repayment would fail because the rating authority could rely either on a defence of "res judicata" (ie the matter had already been finally decided in a previous court action) or on a defence that the claim has already been the subject of a compromise. This amendment implements recommendation 5 (para 3.45) of the report. The defence of res judicata is explained at para 3.41 and the defence of compromise at paras 3.42 and 3.43.

Third, the existing section 20(1) provides that the amount claimed must be "not recoverable apart from this section". These words are repealed and not re-enacted in new section 20. There is no reason to prevent a ratepayer from claiming under the statute a refund of an undue amount paid in error (eg where the rates were paid twice by inadvertence) even though he could recover the amount by a common law action.

In new section 20(1), paragraphs (a) and (b), reproduce the opening words of the existing section 20(1). For an explanation of these words, see para 3.17 of the report.

Subsection (2) of the clause is a transitional provision. Claims made before the appointed day are to be dealt with under the existing provisions of section 20. Claims made thereafter will proceed under new section 20.

But rather rested on the theory that a payment made on that basis is not made under a mistake at all. However that theory was rejected. Therefore such a payment is made under error. Therefore an action for its recovery and the "settled view" rule does operate as a defence. While Lord Lloyd (idem) preferred the term "safeguard" (another term used in our discussion papers), Lord Hope used the term "defence". We have used both of the terms "safeguard" and "defence" in this report.    [Back]

The variables that would be introduced by adopting the "settled view" defence are so numerous that it will almost certainly create greater uncertainty and increase litigation. They referred to two other devices - short time limits and deferment of payment - as possible safeguards for governmental bodies refunding overpaid taxes.    [Back]

Note 156   "The Declaration of the Estates of the Kingdom of Scotland containing the Claim of Right and the offer of the Crowne to the King and Queen of England"; APS 1689, c 28. This enacts: "the give gifts or grants for raiseing of money without the Consent of Parliament or Convention of Estates is Contrary to law".    [Back]

Note 157   The reason for the difference between the taxation provisions of the Claim of Right and of the Bill of Rights probably lies in the different relations between the Crown and the two legislatures in the seventeenth century. The Crown in Scotland was expected to live off its own revenues but "extraordinary taxation", agreed by the Scottish Parliament, had become regular. See G Donaldson Scotland: James V to James VII (1965) p 302; D Stevenson The Scottish Revolution: 1637-44 (1973) p 42. It seems likely that the abuse struck at by the Scottish provisions was the King's alienation to the subject of the power to raise revenues, eg the gift for 16 years by Charles I to the Marquis of Hamilton of the impost on wines, the largest single source of Crown revenues. See D Stevenson "The King's Scottish Revenues and the Covenanters, 1625-1641" (1974) 17 Historical Journal 17 at pp 21, 22. Such grants were thought to make resort to extraordinary Parliamentary taxation necessary.    [Back]

Note 158   1 W & M, c. 36, Article 4 provides: "That levying money for or to the use of the Crowne by pretence of prerogative without grant of Parlyament for longer time or in other manner than the same is or shall be granted is illegal."    [Back]

However the sheriff (8 S at p 129) cited Boog v Magistrates of Burntisland (1775) Mor 1991 in which constitutional principle was relied on and in which Campbell v Hall (1774) 1 Cowp 204; 20 State Trials 239 was cited, though the case did not involve repetition.

Note 180   See eg Burrows, The Law of Restitution (1993) p 354 arguing that if the payment demand falls within the public law doctrine of ultra vires and hence is susceptible to judicial review, the Woolwich rule applies: otherwise not. Contrast J Beatson "Restitution of Taxes, Levies and Other Imposts: Defining the Extent of the Woolwich Principle" (1993) 109 L Q R 401 arguing (especially at pp 417, 418) that the Woolwich principle applies to taxes, duties and imposts levied ultra vires (ie unlawfully) by three categories of payee, namely (1) governmental bodies; (2) other public bodies whose authority to charge is subject to public law principles; and (3) other bodies whose authority to charge is solely the product of statute and thus limited. Professor Birks at one time tentatively argued that the ground of recovery was "transactional inequality": see - P Birks, "The English recognition of unjust enrichment" [1991] LIMCLQ 473 at p 498; P Birks "Restitution from the Executive - A Tercentenary Footnote to the Bill of Rights" in: P D Finn (ed), Essays on Restitution (1990), 164 at pp 175,176. Later he argued that it rested on the need to confine public authorities within their powers ie the public law principle of legality: P Birks, "'When Money is Paid in Pursuance of Void Authority …' - A Duty to Repay?" [1992] Public Law 580 at p 587.    [Back]

Note 273   A decree of dismissal is granted where the defender has entered appearance in the action but the action has been disposed of on the basis of a preliminary plea (eg no title to sue; no jurisdiction; action incompetent in form) rather than on the merits. The action as laid is dismissed but the pursuer may bring a new action on the same ground.    [Back]

Note 274   A decree of dismissal is not res judicata because such a decree merely upholds the defender's plea as to the competency or relevancy of the pursuer's action but not the substantive question of the local authority's liability to refund. The fact that an action is found to be incompetent or irrelevant does not, and should not, prevent the pursuer from raising an action which is competent and relevant. A decree in absence is not res judicata because where the defender does not appear, he cannot be said to have referred his cause to the decision of the court.    [Back]

And at para 4.11 the Paper referred to the Revenue's power to raise additional assessments as being "exercisable even where the taxpayer has furnished correct information and the Revenue alone were responsible for the mistake". The Revenue pointed out that these statements do not accurately reflect the position under self-assessment as the Revenue cannot, outwith the twelve months time limit, assess a taxpayer simply because an error is discovered in the return.

This can be unjust to the payer especially if there is a very short limitation period.    [Back]

Note 418   In the Comateb case [1997] 2 CMLR 649 the European Court held that even though indirect taxes are designed to be passed on to the final consumer and even if in commerce they are normally passed on, it may not be assumed that there is a presumption that indirect taxes have been passed on and that the onus is on the taxpayer to rebut such a presumption.

Note 448   Where relief was given for destitution, the poor law authority could generally not claim repetition from the pauper unless he had obtained the money by false pretences, as by concealing means sufficient for his support: Henderson v Alexander (1857) 29 Sc Jur 559; Kilmartin Inspector of Poor v Macfarlane (1885) 12 R 713; Forfar Parish Council v Davidson (1898) 1F 238; Glasgow Parish Council v Rae (1901) 17 Sh Ct Reps 117; Prudential Assurance Co Ltd v Dalziel Parish Council (1914) 24 Poor Law Magazine 203; Rutherglen Parish v Tolmie 1922 SLT (Sh Ct) 72.

Note 451    Earl of Cawdor v Lord Advocate (1878) 5 R 710.    [Back]

Note 452   [1924] AC 318 (PC). The Crown paid under statute to the Harbour Board money in consideration of the Board granting a lease to a third party. The statute authorised the payment only if the lease was entered into. The Harbour Board was ready to grant the lease on the Crown's request but the Crown never made the request, resumed title to the land, and set off the money against other sums due by the Harbour Board to the Crown. The Harbour Board's action of repayment failed.    [Back]

Note 453    Ibid at pp 326-327 (delivering the judgment of the Board). By "traced" is probably meant ascertaining the recipient, not "tracing" in the sense of English Equity law: Commonwealth of Australia v Burns [1971] VR 525 at p 528 per Newton J.    [Back]

Note 454   This is scarcely surprising because in English law, according to Law Com No 227, para 17.19: "there appear to have been only two reported cases on this topic in almost 400 years" See Doddington's Case (1596) Cro. Eliz. 545: cited in argument in [1924] AC 318 (PC) at p 320.

Note 469   Eg we are not convinced that the apparently absolute nature of the Auckland Harbour Board rule leaves room for developing defences at common law. But, if there is room for such defences it seems unlikely, for example, that "submission to an honest claim" would or should ever be recognised as a defence to the Scottish version of the rule having regard to the different Scottish principles on finality of litigation.
