Hooper v Hooper

This case involved a wife's petition for dissolution of marriage in the Supreme Court of New South Wales, brought under Part III of the Commonwealth's *Matrimonial Causes Act 1945*. The petitioner was domiciled in Tasmania but had resided in New South Wales for over a year, seeking relief based on Tasmanian law. The presiding judge in the Supreme Court of New South Wales raised doubts about the constitutional validity of the Commonwealth Act, leading to the automatic removal of the case to the High Court of Australia under section 40A of the *Judiciary Act 1903-1950*.

The central legal issues before the High Court were whether Part III of the *Matrimonial Causes Act 1945* was a valid exercise of Commonwealth legislative power, particularly concerning the investment of federal jurisdiction in State Supreme Courts, and whether the procedural aspects of the decree, such as the time and manner of making it absolute, were governed by the law of the domicile or the law of the forum. The court was required to determine if a "matter" had arisen under Commonwealth law, as contemplated by section 76(ii) of the Constitution, to justify the conferral of federal jurisdiction under section 77(iii).

The High Court reasoned that Part III of the *Matrimonial Causes Act 1945* validly conferred substantive rights by enabling individuals domiciled in one State but resident in another to institute matrimonial proceedings in the latter State, applying the law of their domicile. This created a "matter" arising under Commonwealth law, thus permitting the investment of federal jurisdiction in State Supreme Courts under section 77(iii) of the Constitution. The court held that the Act did not affect the legislative powers of the States regarding divorce grounds or tribunals, but State legislatures could not abridge the jurisdiction conferred by the Commonwealth Act on State Supreme Courts. Furthermore, the court determined that the form of the decree and the time and manner of its being made absolute were matters of practice and procedure governed by the *lex fori* (the law of the forum), approving the approach taken in *White v. White*.

The Court ordered that the marriage be dissolved on the grounds of desertion, with the decree nisi to be made absolute in the Supreme Court of New South Wales unless cause to the contrary was shown within six months. The costs of the petitioner were to be taxed in the Supreme Court of New South Wales, and the cause was remitted to that court for further proceedings.
