self-governing colonies which, when the Commonwealth came into existence as a new Dominion of the Crown, lost some of their former powers and gained no new powers. They became components of a federation, the Commonwealth of Australia. It became a nation. Its nationhood was in the course of time to be consolidated in war, by economic and commercial integration, by the unifying influence of federal law, by the decline of dependence upon British naval and military power and by a recognition and acceptance of external interests and obligations. With these developments the position of the Commonwealth, the federal government, has waxed; and that of the States has waned. In law that is a result of the paramount position of the Commonwealth Parliament in matters of concurrent power. And this legal supremacy has been reinforced in fact by financial dominance. That the Commonwealth would, as time went on, enter progressively, directly or indirectly, into fields that had formerly been occupied by the States, was from an early date seen as likely to occur. This was greatly aided after the decision in the Engineers' Case, which diverted the flow of constitutional law into new channels." (footnote omitted)
These were the observations of a distinguished legal historian. References to the "federal balance" carry a misleading implication of static equilibrium, an equilibrium that is disturbed by changes in constitutional doctrine such as occurred in the Engineers' Case, and changes in circumstances as a result of the First World War. The error in implications of that kind has long been recognised. So much is evident from Alfred Deakin's Second Reading Speech on the Judiciary Bill in 1902[1] and his comparison between the difficulty of amending the Constitution by referendum, and this Court's differing but continuing role in determining the meaning and operation of the Constitution.

It does not call directly for an examination of what is a trading or financial corporation formed within the limits of the Commonwealth[2]. (Plainly, a foreign corporation is a corporation formed outside the limits of the Commonwealth.) No party or intervener called in question what
