Section 20 provided:
If a copy of the notification in the Gazette, certified under the hand of the Attorney-General, is lodged with the Registrar-General or Registrar of Titles or other proper officer of the State or part of the Commonwealth in which the land is situated, he shall register it in the register and in the manner as nearly as may be in which dealings with land are registered, and shall deal with and give effect to the notification as if it were a grant or conveyance or memorandum or instrument of transfer of the land to the Commonwealth duly executed under the laws in force in that State or part of the Commonwealth.
In their joint judgment Knox C.J. and Starke J. said [15] :
The power conferred by s. 51 (xxxi.) and (xxxix.) of the Constitution is to make laws with respect to the acquisition by the Commonwealth of property, including land, and with respect to matters incidental thereto; and the question is whether a provision entitling the Commonwealth to insist on the registration under the Real Property Act of its title to land acquired under the Lands Acquisition Act, without complying with the conditions imposed by State law on such registration, is incidental to the complete exercise of the power of acquisition. Effective acquisition of (inter alia) land by the Commonwealth is the object to be attained, and the power is completely exercised by enabling the Commonwealth to vest absolutely in itself the land which it desires to acquire. The object is attained by the method provided by s. 16 of the Act, namely, that upon the publication of a notification of acquisition the land described therein shall "by force of this Act be vested in the Commonwealth". This section, the validity of which is not, and cannot be, disputed, confers on the Commonwealth a statutory title to the land required which must, by force of s. 109 of the Constitution and of s. V. of the covering Act, be paramount to any title dependent on a law of the State. The Commonwealth acquires the land and a statutory title to it under a law of the Commonwealth independently of any State law. But it does not follow that the Commonwealth Parliament is entitled to insist upon the State registration of its title to the land acquired unless upon compliance by the Commonwealth with the conditions imposed by State law. The provisions of the Real Property Act 1900 which stand in the way of the Commonwealth in this case in no way prevent or interfere with the acquisition by the Commonwealth of any land in New South Wales: they do no more than prescribe the conditions on which the State will permit the registration of title to land; and in our opinion the Commonwealth, if it desires to obtain registration of its title under the Real Property Act, must comply with the conditions imposed by that Act. As our brothers Isaacs and Rich said, in Commonwealth v. New South Wales [16] , "if it" (i.e., the Commonwealth) "seeks to obtain the registration provided by the statute, it must take it on the terms of the Act which it invokes".
Gavan Duffy J. agreed with that view. Isaacs J. said [17] :
On this occasion a much more radical question was propounded, namely, whether the Registrar-General, as a State officer acting under and by virtue of the State enactment - the Real Property Act, - could be called upon to register any devolutions of title other than those effected as that Act requires, that is, by State Crown grant in the first instance, and then by the various instruments prescribed by the statute as the Registrar's authority to register the new proprietorships. This question, in my opinion, so presented, admits of no doubt. The Commonwealth Parliament has, by s. 20 of the Lands Acquisition Act 1906, purported to require the State Registrar to register a copy of the Governor-General's notification as if it were a grant or conveyance or memorandum or instrument of transfer duly executed under the laws in force in the State. Section 64 also declared that the acquisition under s. 85 of the Constitution shall for the purposes of the Act be deemed an acquisition and vesting under the Act. But as to this there is not even a declaration that any document is to be regarded as a grant, &c., as in s. 20, and I take this provision to be one for compensation in accordance with the Constitution, s. 85. In any case s. 20 of the Act, purporting to require the State officer to treat the copy notification as a State instrument, is invalid. It is, of course, not pretended that, unless expressly authorized, the Commonwealth Parliament can directly repeal or amend State legislation. Where competent, either by concurrent or exclusive powers, Commonwealth Acts repugnant to any State law prevail (see Attorney-General (Ontario) v. Attorney-General for the Dominion [18] ). Section 20, however, is really an amendment of the Real Property Acts of the States, and is a command to a State official as such in the performance of his State functions to disregard the conditions of his statutory authority and to act in accordance with Commonwealth directions.
