Permanent Trustee Australia Ltd v Commissioner of State Revenue (Vict)

The High Court of Australia considered a dispute between Permanent Trustee Australia Limited and the Commissioner of State Revenue (Victoria) concerning stamp duty assessed on a development agreement for land located at Tullamarine Airport. The land in question was vested in the Commonwealth, and the assessment was made under Victorian legislation, purportedly applied to Commonwealth places by the Commonwealth Places (Mirror Taxes) Act 1998 (Cth). The core of the dispute revolved around the constitutional validity of this application of State taxing laws to Commonwealth places.

The legal issues before the Court included whether section 55 of the Constitution, which restricts laws imposing taxation to a single subject and prohibits them from dealing with matters other than the imposition of taxation, applied to a Commonwealth law enacted under section 52(i) of the Constitution (exclusive legislative power over Commonwealth places). The Court also had to determine if the Commonwealth Places (Mirror Taxes) Act 1998 (Cth) impermissibly delegated legislative power, discriminated between States contrary to section 51(ii) or an implied constitutional limitation, or gave preference to one State over another contrary to section 99 of the Constitution. Furthermore, the Court considered whether the decisions in *Worthing v Rowell* and *Allders International Pty Ltd v Commissioner of State Revenue (Vict)* should be reopened.

The Court reasoned that, in light of the dismissal of applications to reopen *Worthing* and *Allders*, the Victorian Stamps Act was invalid to the extent it purported to charge stamp duty on an agreement for a lease of land situated within a Commonwealth place. However, the Court found that the Commonwealth Places (Mirror Taxes) Act 1998 (Cth) was not invalid on the grounds that it dealt with matters other than the imposition of taxation or more than one subject of taxation, contrary to section 55 of the Constitution. The Court adopted the reasoning that provisions for the assessment, collection, and recovery of tax are considered to "deal with" the imposition of taxation, aligning with the purpose of section 55 to prevent "tacking" of unrelated matters. The Court also determined that the Commonwealth Act did not impermissibly delegate legislative power, discriminate between States, or give preference to one State over another.

The Court answered the questions in the Case Stated accordingly. It held that the Stamps Act 1958 (Vic) was invalid to the extent it purported to charge stamp duty on the Development Agreement as a lease or agreement for lease of land within a Commonwealth place. However, it found the Commonwealth Places (Mirror Taxes) Act 1998 (Cth) to be valid and effective to permit the assessment of duty. Permanent Trustee Australia Limited was ordered to pay the costs of the Case Stated.
