“On28 October 2006 , [the taxpayer] was informed that his affairs were under investigation. When the return was examined in October 2006, it was not clear to Dr Branigan and his team how the taxpayer claimed section 37 operated. While this no doubt raised suspicions, even strong suspicions, in the minds of Dr Branigan and his team, this did not make them aware that that return disclosed an insufficiency of tax or that there was a reasonable prospect of establishing that there were such an insufficiency. Accordingly, Dr Branigan wrote to [the taxpayer] on23 October 2006 stating that he had reason to believe that in 2003/04 [the taxpayer] had participated in arrangements whose sole or main purpose was the avoidance of tax and requested the production of certain specified documents. [The taxpayer] declined to produce any documentation and none has ever been produced. At that stage Dr Branigan had not formed a view on whether the scheme was effective.”
“… The word ‘discovers’ does connote change, in the sense of a threshold being crossed. At one point an officer is not of the view that there is an insufficiency such that an assessment ought to be raised, and at another he is of that view. That is the only threshold that has to be crossed. We do not agree that the lawyer… would be regarded as having made a discovery any the less by waking up one morning with a different conclusion from the one he had earlier reached, than if he had changed his mind with the benefit of further research. It is, we think, evident that the relevant threshold for there to be a discovery may be crossed as a result of a ‘eureka’ moment just as much as by painstaking research.”
“the threshold for a ‘discovery’ is now also well established as being a fairly low one. In Charlton it was stated that ‘[a]ll that is required is that it has newly appeared to an officer, acting honestly and reasonably, that there is an insufficiency in an assessment.”
“There is one other aspect of the word “discover” to which I should refer. … “a discovery” is something newly arising, not something stale and old. The conclusion that it is probable that there is an insufficiency must be one which newly arises (from fresh facts or a new view of the law or otherwise).”
“All that is required is that it has newly appeared to an officer, acting honestly and reasonably, that there is an insufficiency in the assessment. That can be for any reason, including a change of view, change of opinion, or correction of an oversight. The requirement for newness does not relate to the reason for the conclusion reached by the officer, but to the conclusion itself. If an officer has concluded that a discovery assessment should be issued, but for some reason the assessment is not made within a reasonable period after their conclusion is reached, it might, depending on the circumstances, be the case that the conclusion would lose its essential newness by the time of the actual assessment. But that would not, in our view, include a case, such as this, where the delay was made to accommodate the final determination of another appeal which was material to the liability question. Such a delay did not deprive [the Inspector’s] conclusions of the essential newness for s 29(1) purposes.”
“Having found errors of approach in the consideration by the First Tier Tribunal, it was appropriate for them [the UT] to exercise their power to remake the decision, making such factual and legal judgments as were necessary for the purpose, thereby giving full scope for detailed discussion of the principle and its practical application. Although no doubt paying respect to the factual findings of the First Tier Tribunal, they were not bound by them. They had all the documentation before the First Tier Tribunal, including witness statements, and transcripts of the evidence and submissions, and detailed written and oral submissions. It is clear that they undertook a thorough exercise involving a hearing lasting six days.”
“I do not suggest that the hypothetical inspector is required to resolve points of law. Nor need he forecast and discount what the response of the taxpayer may be. It is enough that the information made available to him justifies the amendment to the tax return he then seeks to make. Any disputes of fact or law can then be resolved by the usual processes.”
