“The question is whether it means (i) a deliberate statement which is (in fact) inaccurate or (ii) a statement which, when made, was deliberately inaccurate. If (ii) is correct, it would need to be shown that the maker of the statement knew it to be inaccurate or (perhaps) that he was reckless rather than merely careless or mistaken as to its accuracy. We have no hesitation in concluding that the second of those interpretations is to be preferred… Deliberate is an adjective which attaches a requirement of intentionality to the whole of that which it describes, namely ‘inaccuracy’. An inaccuracy in a document is a statement which is inaccurate. Thus the required intentionality is attached both to the making of the statement and to its being inaccurate.”
“In our view, a deliberate inaccuracy occurs when a taxpayer knowingly provides HMRC with a document that contains an error with the intention that HMRC should rely upon it as an accurate document. This is a subjective test.”
“Put simply, in order for HMRC to discharge the burden of demonstrating that an act or omission by a taxpayer was deliberate, they will need to establish to the normal civil standard that the act or omission was intentional; the fact that an act or omission may have been careless, mistaken or stupid is not enough.”
“Where a taxpayer suspects that a document contained an inaccuracy but deliberately and without good reason chooses not to confirm the true position before submitting the document to HMRC then the inaccuracy is deliberate on the part of the taxpayer… However, the suspicion must be more than merely fanciful.”
“Blind-eye knowledge requires… a suspicion that the relevant facts do exist and a deliberate decision to avoid confirming that they exist… In order for there to be blind-eye knowledge, the suspicion must be firmly grounded and targeted on specific facts. The deliberate decision must be a decision to avoid obtaining confirmation of facts in whose existence the individual has good reason to believe.”
