“…the very use of the word ‘judgment’ makes it clear that the commissioners are required to exercise their powers in such a way that they make a value judgment on the material which is before them. Clearly they must perform that function honestly and bona fide… Secondly, clearly there must be some material before the commissioners on which they can base their judgment… Thirdly, it should be recognised, particularly bearing in mind the primary obligation… of the taxpayer to make a return himself, that the commissioners should not be required to do the work of the taxpayer in order to form a conclusion as to the amount of tax which, to the best of their judgement, is due… 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”
“The taxpayer believes that the liability has been excessively calculated and that his ‘admission’ was incorrectly interpreted and misunderstood”
