"if the exercise of reasonable foresight and of due diligence and a proper regard for the fact that the tax would become due on a particular date would not have avoided the insufficiency of funds which led to the default, then the taxpayer may well have a reasonable excuse for non-payment, but that excuse will be exhausted by the date on which such foresight, diligence and regard would have overcome the insufficiency of funds."
"Scott LJ on the other hand is of the opinion that the underlying cause of the insufficiency of funds must be an 'unforeseeable or inescapable event'. I have come to the conclusion that this is too narrow in that (a) it gives insufficient weight to the concept of reasonableness and (b) it treats foreseeability as relevant in its own right, whereas I think that 'foreseeability' or as I would say 'reasonable foreseeability' is only relevant in the context of whether the cash flow problem was 'inescapable' or, as I would say, 'reasonably avoidable'. It is more difficult to escape from the unforeseeable than from the foreseeable."
“(7) If a person who, apart from this subsection, would be liable to a surcharge under subsection (4) above satisfies the Commissioners or, on appeal, a tribunal that, in the case of a default which is material to the surcharge— (a) the return or, as the case may be, the VAT shown on the return was despatched at such a time and in such a manner that it was reasonable to expect that it would be received by the Commissioners within the appropriate time limit, or (b) there is a reasonable excuse for the return or VAT not having been so despatched, he shall not be liable to the surcharge and for the purposes of the preceding provisions of this section he shall be treated as not having been in default in respect of the prescribed accounting period in question (and, accordingly, any surcharge liability notice the service of which depended upon that default shall be deemed not to have been served). (8) For the purposes of subsection (7) above, a default is material to a surcharge if— (a) it is the default which, by virtue of subsection (4) above, gives rise to the surcharge; or (b) it is a default which was taken into account in the service of the surcharge liability notice upon which the surcharge depends and the person concerned has not previously been liable to a surcharge in respect of a prescribed accounting period ending within the surcharge period specified in or extended by that notice.”
"The interpretation of paragraph (b) [of section 59 (8)] is not without its difficulties."
“the tribunal is entitled to have regard in the application of section 59(7) to a prima facie default other than that directly giving rise to the surcharge under appeal for the purpose of determining whether such a default whose existence may affect the amount or existence of the default under appeal, may be ignored. ”
