Antonin Scalia and Bryan A. Garner
That is, at the time the Commonwealth of Australia Constitution was enacted, “Commonwealth” and “Commonwealth entity” or “Parliament of the Commonwealth” meant the non-corporate Commonwealth of the People under a Monarch, and a “Commonwealth” entity/Government/agent was one pursuant to our Constitution, not the Corporations Act 2001 or other Acts that regulate corporations. The “Queen” means the Sovereign of the United Kingdom, Australia and Her other Realms and Territories, and Head of the Commonwealth and includes the predecessors and the heirs and successors of the Sovereign. The “Queen” can not be a legal instrument with no heirs and successors (ie Australia Act 1986 “Queen”)
