"If a legal rule requires a fact to be proved (a 'fact in issue') a judge or jury must decide whether or not it happened. There is no room for a finding that it might not have happened. The law operates a binary system in which the only values are zero and one. The fact either happened or it did not. If the tribunal is left in doubt, the doubt is resolved by a rule that one party or the other carries the burden of proof. If the party who bears the burden of proof fails to discharge it, a value of zero is returned and the fact is treated as not having happened. If he does discharge it, a value of one is returned and the fact is treated as having happened."

" Failure to make returns etc. (1) Where a person has failed to make any returns required under this Act (or under any provision repealed by this Act) or to keep any documents and afford the facilities necessary to verify such returns or where it appears to the Commissioners that such returns are incomplete or incorrect, they may assess the amount of VAT due from him to the best of their judgment and notify it to him."
"What the words 'best of their judgment' envisage, in my view, is that the Commissioners will fairly consider all material placed before them and, on that material, come to a decision which is one which is reasonable and not arbitrary as to the amount of tax which is due. As long as there is some material on which the Commissioners can reasonably act then they are not required to carry out investigations which may or may not result in further material being placed before them"
