Mobil Oil Aust v State of Vic & Anor

In *Mobil Oil Australia Pty Ltd v State of Victoria and Anor*, the High Court of Australia considered a dispute concerning the validity of certain provisions of the *Gas Industry Act 1994* (Vic) and the *Gas Industry (Further Amendment) Act 1994* (Vic). Mobil Oil Australia Pty Ltd, the applicant, challenged the constitutional validity of these Acts, which imposed a levy on gas producers and distributors to fund the Gas Industry Council. The State of Victoria and the Gas Industry Council were the respondents.

The central legal issue before the High Court was whether the impugned legislation, by imposing a levy on gas producers and distributors, constituted an acquisition of property by the State otherwise than on just terms, contrary to section 51(xxxi) of the Commonwealth Constitution. Mobil Oil argued that the levy was a compulsory exaction that amounted to an acquisition of its property without just terms, thereby infringing this constitutional provision.

The High Court, by majority, held that the legislation was constitutionally valid. The majority reasoned that the levy was not an acquisition of property in the constitutional sense. Instead, it was characterised as a tax or a fee for services rendered or to be rendered by the Gas Industry Council, which was established to regulate and promote the gas industry. The Court applied the principle that a compulsory exaction will only amount to an acquisition of property under s 51(xxxi) if it involves the State taking control of, or acquiring an interest in, the property of the subject. In this instance, the levy was found to be a regulatory charge, not an acquisition of property.

Consequently, the High Court dismissed Mobil Oil's application and upheld the constitutional validity of the *Gas Industry Act 1994* (Vic) and the *Gas Industry (Further Amendment) Act 1994* (Vic).
