“In the case of cancellation, refusal or total or partial non-payment, or where the price is reduced after the supply takes place, the taxable amount shall be reduced accordingly under conditions which shall be determined by the Member States. However, in the case of total or partial non-payment, Member States may derogate from this rule.”
“(1) This regulation applies where— (a) there is an increase in consideration for a supply, or (b) there is a decrease in consideration for a supply, which includes an amount of VAT and the increase or decrease occurs after the end of the prescribed accounting period in which the original supply took place. … (2) Where this regulation applies, both the taxable person who makes the supply and a taxable person who receives the supply shall adjust their respective VAT accounts in accordance with the provisions of this regulation. (3) … the maker of the supply shall— (a) in the case of an increase in consideration, make a positive entry; or (b) in the case of a decrease in consideration, make a negative entry, for the relevant amount of VAT in the VAT payable portion of his VAT account. … (4) The recipient of the supply, if he is a taxable person, shall— (a) in the case of an increase in consideration, make a positive entry; or (b) in the case of a decrease in consideration, make a negative entry, for the relevant amount of VAT in the VAT allowable portion of his VAT account. (5) Every entry required by this regulation shall, except where paragraph (6) below applies, be made in that part of the VAT account which relates to the prescribed accounting period in which the increase or decrease is given effect in the business accounts of the relevant taxable person. (6) Any entry required by this regulation to be made in the VAT account of an insolvent person shall be made in that part of the VAT account which relates to the prescribed accounting period in which the supply was made or received. (7) None of the circumstances to which this regulation applies is to be regarded as giving rise to any application of regulations 34 and 35.”
“In this Part— “increase in consideration” means an increase in the consideration due on a supply made by a taxable person which is evidenced by a credit or debit note or any other document having the same effect and “decrease in consideration” is to be interpreted accordingly; … “negative entry” means an amount entered into the VAT account as a negative amount; “positive entry” means an amount entered into the VAT account as a positive amount; “VAT allowable portion”, “VAT payable portion” and “VAT account” have the meanings given in regulation 32 …”
“(1) Every taxable person shall keep and maintain, in accordance with this regulation, an account to be known as the VAT account. (2) The VAT account shall be divided into separate parts relating to the prescribed accounting periods of the taxable person and each such part shall be further divided into 2 portions to be known as “the VAT payable portion” and “the VAT allowable portion”. (3) The VAT payable portion for each prescribed accounting period shall comprise— (a) a total of the output tax due from the taxable person for that period, (b) a total of the output tax due on acquisitions from other member States by the taxable person for that period, (ba) a total of the tax which the taxable person is required to account for and pay on behalf of the supplier, (c) every correction or adjustment to the VAT payable portion which is required or allowed by regulation 34, 35, 38, or 38A, and (d) every adjustment to the amount of VAT payable by the taxable person for that period which is required, or allowed, by or under any Regulations made under the Act. (4) The VAT allowable portion for each prescribed period shall comprise— (a) a total of the input tax allowable to the taxable person for that period by virtue of section 26 of the Act, (b) a total of the input tax allowable in respect of acquisitions from other member States by the taxable person for that period by virtue of section 26 of the Act, (c) every correction or adjustment to the VAT allowable portion which is required or allowed by regulation 34, 35 or 38, and (d) every adjustment to the amount of input tax allowable to the taxable person for that period which is required, or allowed, by or under any Regulations made under the Act.”
“(1) Where a person— (a) has accounted to the Commissioners for VAT for a prescribed accounting period (whenever ended), and (b) in doing so, has brought into account as output tax an amount that was not output tax due, the Commissioners shall be liable to credit the person with that amount. … (1B) Where a person has for a prescribed accounting period (whenever ended) paid to the Commissioners an amount by way of VAT that was not VAT due to them, otherwise than as a result of— (a) an amount that was not output tax due being brought into account as output tax, or (b) an amount of input tax allowable under section 26 not being brought into account, the Commissioners shall be liable to repay to that person the amount so paid. (2) The Commissioners shall only be liable to credit or repay an amount under this section on a claim being made for the purpose. (2A) Where— (a) as a result of a claim under this section by virtue of subsection (1) … above an amount falls to be credited to a person, and (b) after setting any sums against it under or by virtue of this Act, some or all of that amount remains to his credit, the Commissioners shall be liable to pay (or repay) to him so much of that amount as so remains. … (4) The Commissioners shall not be liable on a claim under this section— (a) to credit an amount to a person under subsection (1) … above, or (b) to repay an amount to a person under subsection (1B) above, if the claim is made more than 4 years after the relevant date. (4ZA) The relevant date is— (a) in the case of a claim by virtue of subsection (1) above, the end of the prescribed accounting period mentioned in that subsection, unless paragraph ( b ) below applies; (b) in the case of a claim by virtue of subsection (1) above in respect of an erroneous voluntary disclosure, the end of the prescribed accounting period in which the disclosure was made; … (e) in the case of a claim by virtue of subsection (1B) above, the date on which the payment was made. … (6) A claim under this section shall be made in such form and manner and shall be supported by such documentary evidence as the Commissioners prescribe by regulations; and regulations under this subsection may make different provision for different cases. (7) Except as provided by this section, the Commissioners shall not be liable to credit or repay any amount accounted for or paid to them by way of VAT that was not VAT due to them.”
“[76] Regulation 38 of theVAT Regulations 1995 clearly implements Article 11C.1 in respect of the decrease and Article 11A.1(a) in respect of an increase in consideration obtained. Without regulation 38(1)(a) any increase would not be included in the taxable amount. Both the increase and the decrease in the taxable amount are mandatory under the Directive. In our judgment regulation 38 is mandatory and does require adjustment to the VAT account in the period when the business accounts reflect the change. Although the regulation does not in terms state when the entry is to be made in the VAT account relating to the period it is implicit that it should be at the time. It would be irrational if a trader could delay indefinitely making an entry effecting an increase in consideration. We accept the submission of Dr Lasok [counsel for HMRC] that the failure to make timeous adjustments resulted in overpayments and section 80 therefore applies to the claims. The Appellant did not lose the right to adjust by doing so late; it merely had the consequence that section 80 applied. [77] Mr Cordara [counsel for GMAC] further contended that there was no overpayment in respect of reduction in price taking effect before1 January 1990 the date on which regulation 7 ofThe Value Added Tax (Accounting and Records) Regulations 1989 , the predecessor of regulation 38, took effect. It was common ground that the original returns based on the contractual VAT price were correct and before 1990 there was no statutory mechanism in domestic law for adjustment. The failure of the UK to implement the mandatory requirement of Article 11C.1 before 1990 had the effect that the Appellant could rely on the direct effect of Article 11C.1 from1 January 1978 when the Sixth Directive took effect whereas Customs could not. Consequently the Appellant did not overpay VAT as a result of not making adjustments before 1990 and section 80 does not apply to those adjustments.”
“It follows from arts 22(4)(a) and (b) and 22(5) of the Sixth Directive and s 25(2) and (6) of the 1994 Act, with which reg 29(1) is also consistent, that VAT 'due' and paid to the commissioners in any accounting period under s 80 is the properly charged output for that period for which the taxpayer makes a return less what, if any, sum he claims by way of input tax in the same return. And, consistently with the nature of the right to deduct input tax granted and governed by arts 17 and 18 of the Directive, the nature of the right given to the taxpayer by those provisions of the 1994 Act and the 1995 regulations is essentially a right to a credit, which may be by way of a deduction or repayment depending on whether, in the relevant accounting period the taxpayer is a payment or repayment trader. The fact that, for whatever reason, he may not have claimed any or all the input tax to which he was entitled in that return, is no basis for asserting that the amount of tax accounted for and paid was pro rata 'not due' so as make the payment an overpayment within the meaning of s 80. (In this connection, it should be noted that s 73 of the 1994 Act, which gives the commissioners power to make assessments where taxpayers have failed to make returns, is clearly directed to securing payment of the tax, not to ensuring that they receive due credit for unclaimed inputs.) This conclusion does not depend on when the right to deduct accrued. The fact that there was in any accounting period an unexercised right to deduct input tax does not render part of the payment to the commissioners VAT which was not 'due' for that period for the purpose of s 80 …”
“Section 80 is concerned with cases where a taxpayer has brought into account as output tax an amount that was not output tax due. When GMAC made its supplies and accounted for the full amount of output tax, it accounted for an amount of output tax which was then due: it is only the subsequent failure of the customer to pay which has resulted in any possible claim for bad debt relief. It does not seem to us that later circumstances giving rise to a bad debt for the purposes of Article 11C(1) and which results in a reduction in the chargeable amount renders the amount which was actually paid retrospectively incorrect in the sense that it can be said that the amount actually paid was “not output tax due” within section 80. It was, when paid, output tax which was due; and remained such until a bad debt arose.”
“It follows, unless and until a claim is indicated, that it cannot be said that any relief is to be afforded and that it cannot be said that any amount has been brought into account as output tax that was not output tax due. Accordingly, s 80 does not, in our judgment, in terms apply to GMAC’s claims.”
“… the obligation on the English courts to construe domestic legislation consistently with Community law obligations is both broad and far-reaching. In particular [the obligation]: [1] … is not [to be] constrained by conventional rules of construction (per Lord Oliver of Aylmerton in Pickstone v Freemans plc[1989] AC 66 , 126B); [2] … does not require ambiguity in the legislative language (per Lord Oliver in the Pickstone case, at page 126B and per Lord Nicholls of Birkenhead in Ghaidan v Godin-Mendoza[2004] 2 AC 557 , para 32); [3] … is not an exercise in semantics or linguistics (per Lord Nicholls in Ghaidan's case, at paras 31 and 35; per Lord Steyn, at paras 48-49; per Lord Rodger of Earlsferry, at paras 110 – 115); [4] … permits departure from the strict and literal application of the words which the legislature has elected to use (per Lord Oliver in Litster v Forth Dry Dock & Engineering Co Ltd[1990] 1 AC 546 , 577A; per Lord Nicholls in Ghaidan's case, at para 31); [5] … permits the implication of words necessary to comply with Community law obligations (per Lord Templeman in the Pickstone case, at pp 120H-121A; per Lord Oliver in the Litster case, at p 577A); [6] [accepts that] the precise form of the words to be implied does not matter (per Lord Keith of Kinkel in the Pickstone case, at p 112D; per Lord Rodger in Ghaidan's case, at para 122; per Arden LJ in R (IDT Card Services Ireland Ltd) v Customs and Excise Comrs[2006] STC 1252 , para 114); [7] [is only constrained to the extent that] the meaning should 'go with the grain of the legislation' and be compatible with the underlying thrust of the legislation being construed': see per Lord Nicholls in Ghaidan v Godin-Mendoza[2004] 2 AC 557 , para 33; Dyson LJ in Revenue and Customs Comrs vEB Central Services Ltd[2008] STC 2209 , para 81; [8] [must not lead to an interpretation being adopted] which is inconsistent with a fundamental or cardinal feature of the [national] legislation since this would cross the boundary between interpretation and amendment (see per Lord Nicholls, at para 33, Lord Rodger, at paras 110-113 in Ghaidan's case; per Arden LJ in R (IDT Card Services Ireland Ltd) v Customs and Excise Comrs[2006] STC 1252 , paras 82 and 113) … [9] … cannot require the courts to make decisions for which they are not equipped or give rise to important practical repercussions which the court is not equipped to evaluate: see the Ghaidan case, per Lord Nicholls, at para 33; per Lord Rodger, at para 115; per Arden LJ in the IDT Card Services case, at para 113.”
“The principle of conforming construction is often referred to as the Marleasing principle, named after the ECJ case in which it was first clearly enunciated (Case C-106/89 , Marleasing SA v La Comercial Internacional de Alimentación SA[1990] ECR I-4135 ,[1992] 1 CMLR 305 ,[1993] BCC 421 ). In FII (SC) [2] Lord Sumption at para 176 described the principle, as it has been applied in England, as ‘authority for a highly muscular approach to the construction of national legislation so as to bring it into conformity with the directly effective Treaty obligations of the United Kingdom’. He added that, however strained a conforming construction may be, and however unlikely it is to have occurred to a reasonable person reading the statute at the time, ‘a later judicial decision to adopt a conforming construction will be deemed to declare the law retrospectively in the same way as any other judicial decision’.”
