After giving such consideration as I have been able to give to everything that I have found favourable to the present defendant in all this, I think her objection fails. In the report of Porter's Case [1] the information there laid is set out. The relevant part, after alleging the lands in question were "in the hands and possession of the said lady the now Queen, the 26th day of January in the 34th year of her reign, and long before, and continually afterwards were and stood, and of right ought to be as in the right of her Crown of England, as more fully appeareth of record" yet the defendants, "the laws of the said lady the now Queen little regarding, but intending the disinherison of the same lady the Queen in the premises, with force and arms, etc. the said 26th day of January in and upon the possession of the said lady the now Queen of the premises entered, intruded, and made entry, and the issues and profits thereof arising, took and had to their own uses, and do yet take and have, the trespass aforesaid hitherto and yet continuing, in contempt of the said lady the now Queen, and contrary to her laws ". These allegations were not inconsistent with the royal dignity. The difference between them and the statements in the original writ of ejectio firmae may seem insignificant. A specimen of the writ, as it appears in the Register, is given in Sir William Holdsworth's A History of English Law, 4th ed. (1935) vol. iii, p. 662. It alleged that the defendant had, by force and arms during the currency of the plaintiff's term, entered, carried away his goods and cattle, ejected him from his farm and other enormities done him, to his grave damage and against the King's peace. Slight as the differences in language may seem to-day, the allegations in intrusion could properly be made by the Crown. Those in ejectment could not. Yet, even allowing for the persistence of ancient theory in modern times, it is hard to see why in the first half of the nineteenth century an allegation that Doe, a tenant of the King, had been turned off his land by Roe, a casual ejector, was inconsistent with the royal dignity. Serjeant Adams, the fourth edition of whose work on Ejectment appeared in 1846, thought it was not (p. 56). "It was formerly doubted" he said, "whether an ejectment could be maintained by the King, because an ejectment is for an injury done to the possession, and the King cannot be put out of possession. But this reasoning seems only to apply where the King is made plaintiff, and not where he is the lessor of the plaintiff, for it is the lessee, and not the lessor, who by the legal fiction is supposed to be ousted". This seems to me convincing. I think therefore that the Crown could have taken advantage of the procedure in ejectment before the Common Law Procedure Act. That Act was designed to rationalize the law and to banish Doe and the casual ejector from the courts, but without undoing the good work they had done. Are we to say then that it put the Crown back into its feudal fetters, that what the King could have done with the aid of Doe he could not now do for himself; I think not. It is correctly said in the Introduction to Day on The Common Law Procedure Acts (1861) that the Act of 1852 "abolished the ancient action of trespass and ejectment, in which John Doe complained of the doings of Richard Roe, and it supplied in its place a new and more simple mode of trying the title to real estate. It provided, however, that the effect of a judgment in the new action should be the same as the effect of a judgment in the old". The Act was adopted in New South Wales by 17 Vict. No. 21, which came into force on 1st January 1854. Its purpose and effect appears from s. 119: "Instead of the present proceeding by ejectment a writ shall be issued directed to the persons in possession by name and to all persons entitled to defend the possession of the property claimed which property shall be described in the writ with reasonable certainty". And s. 159 provided that "the effect of a judgment in an action of ejectment under this Act shall be the same as that of a judgment in an action of ejectment heretofore". The corresponding provisions of the Common Law Procedure Acts, 1899-1957, the statute now in force in New South Wales, are in substance the same as those that came into operation in 1854. So that surely what the Crown could have got by the assistance of Doe before 1853, the Crown can now get under the Act? An action of ejectment to-day does not suppose that the Queen has been evicted. The writ is directed to persons in possession. That means, I think, "actual possession" rather than "possession in law" in the contrasting senses defined in the Termes de la Ley. With this meaning the writ is not, I consider, inconsistent with whatever doctrine may still prevail that the Queen cannot be dispossessed by matter in pais. The modern action of ejectment bears an ancient name. Its ancestry goes back to the writ ejectio firmae. But that does not mean that the modern law must carry mediaeval impedimenta. Here the Commonwealth of Australia is the plaintiff. The Crown in right of the Commonwealth brings the action. But it is not asserting rights under feudal law. The Commonwealth acquired this land for the purposes of the Post Office. It acquired it pursuant to the Lands Acquisition Act 1906-1936, s. 57 (1). By that section the Commonwealth held the land as a body corporate, as it does now (see s. 61 of the present Act). As a matter of title it holds it as a tenant in fee simple of the Crown in right of the State of New South Wales. Tenancy in fee simple here describes, not a feudal relationship of the Queen and those who hold land of her, but the nature and quantum of the estate and interest that the Commonwealth has in the land. That use of the term is not new: see Cruise's Digest 4th ed. i, 54; The Commonwealth v. New South Wales [1] ; for "the king or a corporation may be seised of a less estate than a fee simple" [2] .
