“[136] If it is necessary to resolve [whether] ...one or other model is the only possible comparator, we would adopt [the comparator put forward by the taxpayer]. We see this as being a question of law or of mixed fact and law which can properly be the subject matter of an appeal on an issue of law unders11 Tribunals, Courts and Enforcement Act 2007 . [137]…The onus is on HMRC to establish that there is an abuse and thus that the [taxpayer’s comparator] is anti-purposive in the present case. Unless we are persuaded, which we are not, that transactions taking place under the [taxpayer’s comparator] are not normal commercial operations for a developer such as [the taxpayer], abuse cannot be established. In this context, compare Halifax at para 75 where the court said in relation to the second limb that it must be ‘apparent from a number of objective factors that the essential aim of the transactions concerned is to obtain a tax advantage’. This language is not consistent with an obligation on the taxpayer to show the reverse.”
“[62] Even if the FTT had accepted that HMRC had the burden of proving abuse of law, it is far from clear to us that the FTT would have required HMRC to open the case or that, if it had, a submission that the Appellants had no case to answer would have been either appropriate or successful. Under rules 5 and 15 of theTribunal Procedure (First-tier Tribunal) (Tax Chamber) Rules 2009 , the FTT has wide powers to regulate the conduct of proceedings and the evidence before it. Even if the FTT had concluded that HMRC had the burden of proving that the Halifax principle was engaged, it could have required the Appellants to lead evidence about the transactions and the background to them. Further, in considering a submission of no case to answer, the FTT could take account of the documents before it, whether formally produced by witnesses or not, and require witnesses to give evidence about such documents. It follows that we reject this ground of appeal.”
“….The scheme of the 1972 Act appears to me to be this, that if the taxpayer omits to include in his return something which the commissioners consider, using their proper judgement, is taxable, then the commissioners can, using the best of their judgment, assess the taxpayer at a certain figure…, and if there is no appeal, that figure is then deemed to be the tax payable. If the taxpayer wishes to have the assessment altered, he must go to the tribunal, and unless the tribunal finds the commissioners are wrong, the assessment still stands. It seems to me, in those circumstances, that any taxpayer who appeals to the tribunal takes upon himself the burden of proving the assertion he makes, namely that the assessment is wrong, because unless he proves this there is nothing on which the tribunal can find an error in the assessment. The facts and figures are known to him….” “Now there is no principle of law which I know of – and both counsel disclaim it – that where a provision is a taxing provision the onus of proof is on the tax gatherer, while if it is a mitigating provision it is on the taxpayer, and to this extent the ratio of the Ivy Café case is, in my view, wholly wrong. But that the onus of adducing evidence and satisfying the tribunal that the assessment is wrong lies on the appellant under s 40 [now s 83 VATA] I have not any doubt at all.”
“There is every reason to assume that the legislature did not intend to confer upon a potential taxpayer the valuable privilege of disqualifying himself [from liability to an assessment] by the simple and relatively unskilled method of losing either his memory or his books.”
“The element of guesswork and the almost unavoidable inaccuracy in a properly made best of judgement assessment, as the cases have established, do not serve to displace the validity of the assessments, which are prima facie right and remain right until the taxpayer shows that they are wrong and also shows positively what corrections should be made in order to make the assessments right or more nearly right. It is also relevant, when considering the sufficiency of evidence to displace an assessment, to remember that the facts are peculiarly within the knowledge of the taxpayer.”
“it is the taxpayer who knows and the taxpayer who is in a position (or, if not in a position, who certainly should be in a position), to provide the right answer, and chapter and verse for the right answer.”
“[81] … It is plain that if HMRC wishes to assert that a trader’s state of knowledge was such that his purchase is outwith the scope of the right to deduct it must prove that assertion.”
“Where such a question is raised before any…tribunal of a Member State, that ...tribunal may, if it considers that a decision on the question is necessary to enable it to give judgment, request the Court to give a ruling thereon.”
“if the facts have been found and the Community Law issue is critical to the court’s final decision, the appropriate course is ordinarily to refer the issue to the Court of Justice unless the national court can with complete confidence resolve the issue itself….If the national court has any real doubt, it should ordinarily refer.”
“…A measure of self-restraint is required on the part of the national courts, if the Court of Justice is not to become overwhelmed…. …[a] development which is unquestionably significant is the emergence in recent years of a body of case-law developed by this court to which national courts and tribunal can resort in resolving new questions of Community law. Experience has shown that, in particular in many technical fields, such as customs and value added tax, national courts and tribunals are able to extrapolate from the principles developed in this court’s case law. Experience has shown that the case-law now provides sufficient guidance to enable national courts and tribunals – and in particular specialised courts and tribunals – to decide many cases for themselves without the need for a reference…”
