The question here is, does that principle, under the Constitution of Queensland, extend so far as to exempt a Justice of the Supreme Court of Queensland from liability to pay income tax in respect of his official salary; or rather, so far as to enable him to exclude his official salary from his statement of the income on which he is to pay tax. This question is to be faced on considerations quite different from those discussed in Deakin v. Webb[3] and in Webb v. Outtrim[4] as to the salary of federal officers. In the case of a State taxing the income of a federal officer, there is, or may be, a clashing of what may be called, though not quite accurately, two sovereignties. The view of the High Court, as stated in Deakin v. Webb[5], is that the recompense of a federal officer is not to be lessened, nor the full exercise of the executive or judicial power of the Commonwealth interfered with, except by that power - the federal power - from which the officer derives his appointment. Whatever may be our views as to the decision in Deakin v. Webb[6], or as to the effect of the more recent decision of the King in Council in Webb v. Outtrim[7], in this case there is no such conflict of State power with federal power. Here it is the Queensland legislature which purports to exact from its State Judges income tax, according to the same scale as from every other citizen. The question is, does the Queensland Constitution forbid such taxation on the official salary of the State Judges? In the first place, I entertain no doubt, notwithstanding the ingenious argument of counsel for the appellant, that the Queensland legislature, by the Income Tax Act Amendment Act 1904, intended to tax the Judges (see Income Tax Act 1902, sec. 3, "income derived from personal exertion," secs. 7, 12, 58). In sec. 12, there is an express exemption of the Governor "in respect of the emolument of his office as Governor"; and there is no such exemption provided for the official emolument of Judges. In sec. 58, it is provided that no Judge shall on account of his liability to tax under this Act be debarred from dealing with any matter upon which he may be called upon to adjudicate under this Act. Moreover, if any doubt could linger after such provisions, that doubt is, in my opinion, absolutely settled by the declaratory Act of 1905 (No. 34 of 5 Edw. VII.). For in this Act it is declared that each of the persons for the time being holding the office of Chief Justice is and always has been chargeable with, and liable to pay, income tax in respect of his official salary. But the question remains, does the Queensland Constitution, as distinguished from the Queensland Acts of Parliament, forbid the levying of such a tax on the Judges? As usually happens in constitutional cases, the controversy has raised a great number of curious and delicate points, but in the end the issue is reduced to a very narrow compass, and here it is as to the meaning of sec. 17 of the Constitution Act 1867. I assume, in favour of the appellant, that this Act, and particularly this section, were authorized by the Imperial Act 18 & 19 Vict. c. 54, sec. 7, and by the Order in Council thereunder of the 6th June 1859. I assume also that, notwithstanding the exceptionally wide and very peculiar powers contained in par. xxii. of the Order in Council, of altering the Constitution, the legislature of Queensland has no power to pass a law forbidden by the Constitution as it stands, unless and until the Constitution has been definitely so altered, with His Majesty's consent, as to give the legislature power to pass such a law. I understand that it is the particular desire of the appellant to test the power of legislating in defiance of the Constitution, to test the validity of the declaratory Act of 1905 on the assumption that it is in violation of the Constitution. But it is not necessary for the purpose of the decision in this case to decide such a point, for, in my opinion, the declaratory Act of 1905 is not in violation of the Constitution. The point may never come for decision; but, if it should, it will be well if it can be approached as a fresh subject uninfluenced by any expressions of opinion made in a case that has been solved on other and narrower grounds. I do not think that the mind bestows the same searching scrutiny on a point which is not necessary for a decision as on a point which is necessary. I confine my decision to sec. 17 of the Constitution. When the Constitution says that the salary shall in all time coming be paid and payable to every such Judge and Judges for the time being so long as the patents or commissions for them or for any of them respectively shall continue and remain in force, does it involve the proposition that the Judges shall not be liable to any taxation in respect of their salaries as Judges? Does this provision for payment in full of the salary involve, by necessary implication, that the legislature is prohibited also from compelling an increase of the expenditure of the Judges? The question really carries its own answer on its face. The protection of the Constitution extends only up to the time that the money gets into the possession of the Judge. The money must get there; but there is nothing said as to what may happen afterwards. In this case, the salary for 1905, which is the basis of assessment, has in fact been received in full by the appellant; and, in my opinion, this satisfies the requirements of the Constitution. It is urged that if the Commissioner's view is right there will be nothing to hinder the Crown from deducting the income tax from the salary before payment. But this result by no means follows. In England there is an express power to make such a deduction (5 & 6 Vict. c. 35, sec. 146, Schedule E. Rule 3). At all events, the difficulty has not yet arisen, for the salary has been paid in full. For my part, I am at present strongly inclined to think - and I state my present opinion because it confirms me in my view of the main question - that the income tax cannot be so deducted before payment of the salary, and that a Queensland Act providing for such a deduction would, in the present state of the Constitution, be ultra vires and void. The Constitution provides that the salary shall be "paid and payable"; and, in my opinion, nothing that will not support a plea of payment will be a sufficient answer to a Judge's claim for salary. Even if the income tax were made payable before or on the same day as the Judge received his salary, I think that the Crown could not refuse to pay the salary on the ground that it has a set-off. Where has the right to set-off been given? At common law, a defendant, who had a cross claim, had to bring a cross action. The right to set-off is purely statutory (2 Geo. II. c. 22, sec. 13): Liskeard and Looe Railway Co. v. Liskeard and Caradon Railway Co.[8]. A fortiori, a counterclaim cannot be used so as to enable the Crown to escape payment. But the protection of the Constitution does not go farther than actual payment; and we have no right to give a meaning to the words of the Constitution which the words do not bear in themselves, on the grounds urged by counsel - that, without further protection, the independence of the Judges has not been secured by the Constitution against all possible risks. That is a matter for the framers of the Constitution. It has to be remembered that the protection given, according to our construction, extends as far as that given to the English Judges; and it is in most, if not all, of the States, stronger in quality, by virtue of the sections forming part of a written Constitution, a fundamental law. The sections of the Queensland Constitution, secs. 16-18, follow almost verbatim the words of the English Act 1 Geo. III. c. 23. The British Parliament has uncontrolled power to alter that Act at its will, but it has never been altered; and yet the words in that Act have not prevented the English Parliament from making the Judges as well as others liable to income tax. The British Income Tax Act 1842 makes the Judges liable to the same income tax as other citizens; and, as I have said, it specifically enables the tax to be deducted from their salaries. Perhaps it is not an unfair inference that the Queensland legislature, in adopting the Queensland Constitution in 1867, and the Privy Council in framing the Order in Council in 1859, did not, in using the same words as the Act 1 Geo. III. c. 23, intend to give the Queensland Judges an immunity from a tax to which the English Judges were already subject. The same Act (1 Geo. III. c. 23) has been embodied in most, if not all of the Constitutions of the Australian Colonies; and there is no instance on record of a Judge in Australasia having escaped the payment of an income tax by reason of those words in the Constitution. I am, therefore, of opinion that both questions in this special case should be answered in the affirmative; and as to the amount of income tax to be paid there is no contest.
