The legal process required at the federal level remains, theoretically, unclear. The Australian constitution, as was noted during the crisis of 1936, contains no power for the federal parliament to legislate with respect to the monarchy. Everything thus turns upon the status and meaning of clause 2 in the Commonwealth of Australia Constitution Act 1900, which provides: "The provisions of this Act referring to the Queen shall extend to Her Majesty's heirs and successors in the sovereignty of the United Kingdom."
