“71 Construction of sections 59 to 70 (1) For the purpose of any provision of sections 59 to 70 which refers to a reasonable excuse for any conduct— ( a ) an insufficiency of funds to pay any VAT due is not a reasonable excuse; and ( b ) where reliance is placed on any other person to perform any task, neither the fact of that reliance nor any dilatoriness or inaccuracy on the part of the person relied upon is a reasonable excuse. (2) In relation to a prescribed accounting period, any reference in sections 59 to 69 to credit for input tax includes a reference to any sum which, in a return for that period, is claimed as a deduction from VAT due.”
“In our judgment, there is nothing in the VAT default surcharge which leads us to the conclusion that its architecture is fatally flawed. There are, however, some aspects of it which may lead to the conclusion that, on the facts of a particular case, the penalty is disproportionate. But in assessing whether the penalty in any particular case is disproportionate, the tribunal must be astute not to substitute its own view of what is fair for the penalty which Parliament has imposed. It is right that the tribunal should show the greatest deference to the will of Parliament when considering a penalty regime just as it does in relation to legislation in the fields of social and economic policy which impact upon an individual’s convention rights. The freedom which Parliament has in establishing the appropriate penalties is not, we think, necessarily exactly the same as the freedom which it has in accordance with its margin of appreciation in relation to convention rights (and even there, as we have explained, the margin of appreciation will vary depending on the right engaged).”
