disclose that for the English annual accounting periods ending respectively 31st January 1920 and 1921, the sum of £21,478 10s., portion of the £68,914, was set off against the excess profits duty payable. The set-off was a statutory requirement (sec. 38 (3) of the Finance Act 1921, and rule 6 of Part IV. of the Second Schedule). As to this part, the taxpayer, in my opinion, fails at the threshold. That sum was never "paid." The balance of the sum of £68,914, namely, £47,435 10s., was applied by the British Treasury as follows :-Portion, namely, £12,042 14s. was applied, and necessarily by mutual consent, to discharge liabilities of the taxpayer other than excess profits duty, and this is equally equivalent to repayment. The residue, £35,392 16s., was paid to the taxpayer in cash on 19th August 1922. Again applying rule 6 of Part IV. of the Schedule of the Act of 1921, the whole sum of £47,435 10s. was a "repayment" to the taxpayer by the Government of the United Kingdom, and necessarily a repayment of excess profit duties paid by the taxpayer.
But there still arises the main question that divides the parties here, namely, has the sum of £47,435 10s., which was unquestionably previously paid to the United Kingdom for excess profit duties, and while remaining unrepaid, unquestionably "paid" within the meaning of the Australian Act, either wholly or as to a proper proportionate part thereof, in respect of all Australian war-time profits within the meaning of sec. 15 (4) of the War-time Profits Tax Assessment Act, now, since repayment under the Act of 1921, lost its "paid" character for Australian purposes ? As to this, in the first place, I retain the test view I expressed in Murray's Case (1). Of course, the letter of the statute must be adhered to, that is to say, the true sense of the words as written must not be modified by notions of policy. But one must always read a statutory provision as a whole in order to understand every part. For instance, if under their power to make assessments and collect duty for an accounting period, notwithstanding an appeal pending, the Commissioners of Inland Revenue were to collect £100,000, which was afterwards found judicially to be reducible to £30,000, leading to a repayment of £70,000, could it be said with any show of right or reason that £100,000 had been "paid" within the meaning of the
