“Operational duty”; “Special Police Services”or“SPS”; “reactive” policing; and, “preventive” policing. In paragraph [6] of the Judgment I stated: “In this judgment I have used various expressions to describe the difference between the policing services that can and cannot be charged for. These are not terms of art but are useful in differentiating between the most important situations that arise in cases such as the present. I provide below a brief description of these terms. i) I use the expression ‘operational duty’ to describe the obligation of the Police to provide services for which no charge may be levied. I use the phrase as shorthand for those activities which constitute the core of the public responsibilities of the Police. It is important to recognise that in the performance of this duty the Police retain a discretion as to how resources are allocated and therefore the prima facie duty arises upon the independent (i.e. unrequested) exercise of the discretion to allocate resources; ii) I use the expression ‘SPS’ as shorthand for ‘Special Police Services’. These are services for which the Police may levy a charge and they are services which in a given case when provided are pursuant to a request and are not pursuant to the operational duty. iii) I use the expression ‘reactive’ to describe policing services which are in response to actual or imminent disorder or crime. iv) I use the expression ‘preventative’ to describe the provision of Police services which are intended to prevent the emergence of crime or disorder, i.e. are not reactive and in response to actual crime or anticipated, imminent crime. For the avoidance of doubt nothing in this judgment is intended to define what, in a given case, may be understood as ‘imminent’.”
“25 Provision of special services. (1) The chief officer of police of a police force may provide, at the request of any person, special police services at any premises or in any locality in the police area for which the force is maintained, subject to the payment to the police authority of charges on such scales as may be determined by that authority.”
"There is a moral duty on each party to the dispute to do nothing to aggravate it and to take reasonable means of self-protection, but the discharge of this duty by them is not a condition precedent to the discharge by the Police authority of their own duty."
"… where in the case of any action for which a period of limitation is prescribed by this Act, either – (a) … (b) … (c) the action is for relief from the consequences of a mistake; the period of limitation shall not begin to run until the plaintiff has discovered the fraud, concealment or mistake (as the case may be) or could with reasonable diligence have discovered it. References in this subsection to the defendant include references to the defendant's agent and to any person through whom the defendant claims and his agent."
“The ‘reasonable diligence’ proviso depends upon the true state of affairs being there to be discovered. In this case, however, the true state of affairs was not discoverable until the Court of Justice pronounced its judgment […] they could not have discovered the truth because the truth did not yet exist. In my opinion, therefore, the mistake was not reasonably discoverable until after the judgment had been delivered.”
“At this point it is, in my opinion, appropriate to draw a distinction between, on the one hand, payments of taxes and other similar charges and, on the other hand, payments made under ordinary private transactions. The former category of cases was considered by your Lordships’ House in Woolwich Equitable Building Society v Inland Revenue Commissioners [1993] A.C. 70, in which it was held that at common law taxes exacted ultra vires were recoverable as of right, without the need to invoke a mistake of law by the payer.”
“… money paid by a citizen to a public authority in the form of taxes or other levies paid pursuant to an ultra vires demand by the authority is prima facie recoverable by the citizen as of right.”
“But money paid under compulsion may be recoverable. In particular: (a) Money paid as a result of actual or threatened duress to the person, or actual or threatened seizure of a person’s goods, is recoverable. For an example of the latter, see Maskell v. Horner[1915] 3 KB 106 . Since these forms of compulsion are not directly relevant for present purposes, it is unnecessary to elaborate them; but I think it pertinent to observe that the concept of duress has in recent years been expanded to embrace economic duress. (b) Money paid to a person in a public or quasi-public position to obtain the performance by him of a duty which he is bound to perform for nothing or for less than the sum demanded by him is recoverable to the extent that he is not entitled to it. Such payments are often described as having been demanded colore officii. There is much abstruse learning on the subject (see, in particular, the illuminating discussion by Windeyer J. in Mason v. Stale of New South Wales(1959) 102 CLR 108 , pages 139-142), but for present purposes it is not, I think, necessary for us to concern ourselves with this point of classification. Examples of influential early cases are Morgan v. Palmer (1824) 2 B & C 729 and Steele v. Williams (1853) 8 Ex 625; a later example of some significance is T. & J. Brocklebank Ltd. v. The King[1925] 1 KB 52 . (c) Money paid to a person for the performance of a statutory duty, which he is bound to perform for a sum less than that charged by him, is also recoverable to the extent of the overcharge. A leading example of such a case is Great Western Railway Co. v. Sutton (1869) LR 4 HL 226; for a more recent Scottish case, also the subject of an appeal to this House, see South of Scotland Electricity Board v. British Oxygen Co.Ltd.[1959] 1 WLR 587 . (d) In cases of compulsion, a threat which constitutes the compulsion may be expressed or implied (a point perhaps overlooked in Twyford v. Manchester Corporation[1946] Ch 236 ). (e) I would not think it right, especially bearing in mind the development of the concept of economic duress, to regard the categories of compulsion for present purposes as closed.”
“The justice underlying the Woolwich’s submission is, I consider, plain to see. Take the present case. The Revenue has made an unlawful demand for tax. The taxpayer is convinced that the demand is unlawful, and has to decide what to do. It is faced with the Revenue, armed with the coercive power of the State, including what is in practice a power to charge interest which is penal in its effect. In addition, being a reputable society which alone among building societies is challenging the lawfulness of the demand, it understandably fears damage to its reputation if it does not pay. So it decides to pay first, asserting that it will challenge the lawfulness of the demand in litigation. Now, the Woolwich having won that litigation, the Revenue asserts that it was never under any obligation to repay the money, and that it in fact repaid it only as a matter of grace. There being no applicable statute to regulate the position, the Revenue has to maintain this position at common law. Stated in this stark form, the Revenue’s position appears to me, as a matter of common justice, to be unsustainable; and the injustice is rendered worse by the fact that it involves, as Nolan J. pointed out, the Revenue having the benefit of a massive interest-free loan as the fruit of its unlawful action. I turn then from the particular to the general. Take any tax or duty paid by the citizen pursuant to an unlawful demand. Common justice seems to require that tax to be repaid, unless special circumstances or some principle of policy require otherwise; prima facie, the taxpayer should be entitled to repayment as of right.”
“At this point it is, in my opinion, appropriate to draw a distinction between, on the one hand, payments of taxes and other similar charges and, on the other hand, payments made under ordinary private transactions. The former category of cases was considered by your Lordships' House in Woolwich Equitable Building Society v. Inland Revenue Commissioners[1993] AC 70 , in which it was held that at common law taxes exacted ultra vires were recoverable as of right, without the need to invoke a mistake of law by the payer.”
“13. There is no doubt that the regimes are different. Both the Woolwich principle and section 33 apply only to the recovery of money paid as taxes or the like. They do not apply to ‘private transactions’. The Woolwich principle is indifferent as to whether the taxpayer paid the tax because he was mistaken or, as in Woolwich, for some other reason. And section 33 has its own rules. So the regime for taxes is certainly different. But the question is whether Lord Goff meant to say that the remedies provided by the two regimes are mutually exclusive. Woolwich and section 33 are available only for ‘taxes and other similar charges’. Does it follow that the common law rule for recovery of payments made by mistake, as applied to private transactions in Kleinwort Benson, does not apply to taxes? That would be going a good deal further. It is one thing to say that the regimes are different and another to say that their remedies are mutually exclusive.”
“40. We can see what he made of the argument that the Revenue was in a special position in the Woolwich case at pp 171-172. The Revenue had made an unlawful demand for tax but it was asserting that it was under no obligation to pay back the money. That position seemed to him, as matter of common justice, to be untenable – a position made worse by the fact that it involved the Revenue having the benefit of a massive interest-free loan as the fruit of its unlawful action: ‘Common justice seems to require that tax to be repaid, unless special circumstances or some principle of policy require otherwise; prima facie, the taxpayer should be entitled to repayment as of right’.”
“It also fails to take account of the fact that in the Woolwich case there was no error of law by the taxpayer. So the House was not called upon to consider the effect of a mistake of law in that case at all. Lord Goff's use of the phrase ‘or other similar charges’ is perfectly intelligible it is understood as referring to the case of an ultra vires demand. All statutory charges which are the subject of an ultra vires demand fall easily within this category.”
“44. The submission that the restitutionary remedy for payments made under a mistake is subject to an exception in favour of the Revenue where the mistake was one of law runs into difficulty as soon as it is articulated. It seeks to build in two exceptions, not just one, into the generality of the remedy that was recognised in Kleinwort Benson. … The second would involve treating the Revenue differently from all other public authorities which receive payments made under a mistake of law. If this argument were to succeed it would have a significant impact on the law's taxonomy. English law has been moving step by step towards a principled statement of the law of restitution. The carving out of exceptions which are not clearly based on principle would risk reversing this process.”
“…that when a man pays more than he is bound to do by law for the performance of a duty which the law says is owed to him for nothing, or for less than he has paid, there is a compulsion or concussion in respect of which he is entitled to recover the excess…”
“The second point of the appellants is that, on the assumption that the first appellants have exercised undue discrimination against the respondents, the latter have no remedy by way of recovery of any sums paid under a tariff which has been brought into force. … In my opinion, the first governing principle is that a tariff which imposes a charge upon the respondents, involving their being unduly discriminated against, is contrary to section 37 (8) of the Electricity Act, 1947. The respondents were charged more than is warranted by the statute… In principle, the appellants should not be permitted to retain payments for which they have no warrant to charge. The respondents, may, therefore, recover whatever sum they may be able to prove was in excess of such a charge as would have avoided undue discrimination against them. I do not understand it to be disputed that the charges to the low-voltage consumers are correct. It is fully within the competence of a Court on the evidence before it to estimate the amount by which the respondents have been overcharged, and the respondents have, in my view, averred with sufficient specification the standard by which that amount should be estimated.”
“173. It is fair to look for the reasoning of the House of Lords mainly in the classic analysis of Lord Goff, although similar points were made by Lord Browne-Wilkinson, who agreed with Lord Goff in terms and by Lord Slynn, who agreed with him in substance. It is apparent that the mischief which justified in Lord Goff's eyes a special rule for unlawful charges by public authorities was (i) that no tax should be collected without Parliamentary authority, and (ii) that citizens did not deal on equal terms with the state, and could not be expected to withhold payment when faced with the coercive powers of the Revenue, whether those powers were actually exercised or merely held in reserve: see pp. 172. At pp. 175-176, Lord Goff adopted the dissenting judgment of Wilson J in the Supreme Court of Canada in Air Canada v British Columbia [1989] 59 DLR (4th) 161. In her judgment, Wilson J had expressed the view that there was a general right to recover money paid under unconstitutional legislation, and deprecated any suggestion that it must have been paid under protest. The reason, as she pointed out at p 169, was that the legislature holds out its legislation as valid and that any loss resulting from payment under it "should not fall on the totally innocent taxpayer whose only fault is that it paid what the legislature improperly said was due". The emphasis in this reasoning was on the unlawful character of the legislation, with which in practice the citizen was bound to comply even if it might subsequently be shown to be void. This approach has subsequently been adopted by the Supreme Court of Canada in Kingstreet Investments Ltd v New Brunswick (Finance)[2007] 1 SCR 3 , to which I have already referred in another context. Lord Goff not only found the reasoning of Wilson J ‘most attractive’ (p 176D), but expressed his own conclusions in very similar terms. ‘In the end’, he said (p 173), ‘logic appears to demand that the right of recovery should require neither mistake nor compulsion, and that the simple fact that the tax was exacted unlawfully should prima facie be enough to require its repayment’. The ‘exaction’ of which he is speaking here is not confined to demands by any particular administrative agency of the state. It includes exaction by the state by enacting void legislation, which taxpayers are likely to pay because they know that the state will act on the footing that it is valid. It is not a condition of the taxpayer's right of recovery that it should have put the matter to the test by waiting until the Inland Revenue insisted. In a passage at p 177 which strikingly foreshadows some of the issues in the present appeals, Lord Goff assimilated the rule of English law as he had formulated it to the absolute right of recovery recognized by the European Court of Justice in San Giorgio (Case 199/82) [1983] ECR 3595 in cases where tax was charged contrary to EU law. Although the majority of the appellate committee stopped well short of adopting a concept of ‘absence of legal basis’ as a general ground of recovery even in cases of taxation without lawful authority, Lord Browne-Wilkinson's analysis of the legal basis of recovery in such cases was also very similar to that of the case law of the Court of Justice. Money unlawfully ‘demanded’ was recoverable because it was paid for no consideration: see p 198. 174. The word ‘demand’ as it was used in the speeches in Woolwich Equitable referred in my view simply to a situation in which payment was being required of the taxpayer without lawful authority. Nothing in the principle underlying the decision turned on the mechanism by which that requirement was communicated to the taxpayer. It is therefore a matter of supreme indifference whether it was communicated by assessment, or by some other formal mode of demand, or by proceedings for enforcement, or by the terms of the legislation itself coupled with the knowledge that the Inland Revenue would be likely to enforce it in accordance with those terms.”
“79. In these circumstances it is in my view open to this court (whether or not it was strictly open to the Court of Appeal) to state clearly that where tax is purportedly charged without lawful parliamentary authority, a claim for repayment arises regardless of any official demand (unless the payment was, on the facts, made in order to close the transaction). The same effect would be produced by saying that the statutory text is itself a sufficient demand, but the simpler and more direct course is to put the matter in terms of a perceived obligation to pay, rather than an implicit demand. That is how it was put by Wilson J in her well known dissent in Air Canada v British Columbia [1989] 59 DLR (4th) 161, 169: ‘It is, however, my view that payments made under unconstitutional legislation are not 'voluntary' in a sense which should prejudice the taxpayer. The taxpayer, assuming the validity of the statute as I believe it is entitled to do, considers itself obligated to pay. Citizens are expected to be law-abiding. They are expected to pay their taxes. Pay first and object later is the general rule. The payments are made pursuant to a perceived obligation to pay which results from the combined presumption of constitutional validity of duly enacted legislation and the holding out of such validity by the legislature. In such circumstances I consider it quite unrealistic to expect the taxpayer to make its payments “under protest”
“If the rule in Woolwich is underpinned by broadly conceived rule of law considerations, then this suggests that claims should lie not only against government bodies who have demanded tax but also against any other sort of public authority which has acted beyond its powers to demand duties, fees and other levies.”
“In this appeal, the quantum meruit refers to the value of the services rendered by Mr Benedetti in circumstances where there was no contract which expressly provided how the price he was to be paid for the Services was to be quantified. In awarding a quantum meruit for a benefit, the court is essentially deciding how much is deserved for the conferment of that benefit (and, as Arden LJ pointed out in the Court of Appeal, the literal translation of quantum meruit is ‘as much as he deserves’–[2010] EWCA Civ 1427 , paragraph [2]”
"The estimated amount for which an asset or liability should exchange on the valuation date between a willing buyer and a willing seller in an arm's length transaction after proper marketing and where the parties had each acted knowledgeably, prudently and without compulsion."
“63. Police operations conducted on the public highway or in villages will not ordinarily be conducted for the benefit or protection of particular persons such as those organising occasions like sporting events or music festivals and their attendees. Rather, their purpose will be for the protection of the public at large. That, in my judgment, was their predominant purpose in this case albeit this was occasioned by the existence of the festival. 64. The distinction in Harris between policing outside the football ground and within the football ground has been picked up in a number of Home Office circulars and documents, for example Home Office Circulars 36/1991 and 34/2000. While these documents cannot determine the law, they are a useful guide to how it has been pragmatically applied.”
“…the loss on the late payment of a debt may include an element of compound interest”
“But the claimant must claim and prove his actual interest losses if he wishes to recover compound interest, as is the case where the claim is for a sum which includes interest charges. The claimant would have to show, if his claim is for ancillary interest, that his actual losses were more than he would recover by way of interest under the statute. In practice, especially where the period over which interest is sought is short or where the claimant does not have to borrow money to replace the debt, simple interest undersection 35A of the Supreme Court Act 1981 is likely to be the more convenient remedy.”
“… a recipient of a payment made by a mistake shared by both parties might make no actual use of the money. He might pay the money into a current account at a bank yielding little or no interest. When the mistake comes to light he repays the money. In such a case, depending on the circumstances, it might well be most unfair that he should be out of pocket by having to make an additional payment, whether as compound interest or even simple interest, in respect of the 'time value' of the money he received.”
“119. … To avoid what would otherwise be an unjust outcome the court can, in an appropriate case, depart from the market value approach when assessing the time value of money or, indeed, when assessing the value of any other benefit gained by a defendant. What is ultimately important in restitution is whether, and to what extent, the particular defendant has been benefited: see Professor Burrows, The Law of Restitution, 2nd ed, (2002), page 18. A benefit is not always worth its market value to a particular defendant. When it is not it may be unjust to treat the defendant as having received a benefit possessing the value it has to others. In Professor Birks' language, a benefit received by a defendant may sometimes be subject to 'subjective devaluation': An Introduction to the Law of Restitution (1985), page 413. An application of this approach is to be found in the Court of Appeal decision in Ministry of Defence v Ashman[1993] 2 EGLR 102 . Whether this is to be characterised as part of the 'change of position' defence available in restitution cases is not a matter I need pursue.”
“The discretionary nature of an equitable award of interest provides the necessary flexibility, though I would expect the principles for the exercise of the discretion to develop along familiar and predictable lines”
“In my view (and in agreement with my noble and learned friend Lord Scott of Foscote), if any claim to restitution is to be recognised in relation to the use of money had and received, at common law or in equity, it must refer to any actual benefit obtained by the recipient, here the Revenue. The critical point is that Sempra's restitutionary claims - based on the Revenue's demand or on Sempra's own mistake - are not for damages or in respect of any wrong”
“…restitution on the basis of unjust enrichment looks, carefully and advisedly, at the recipient's actual benefit”
