Philip Morris Limited v Commonwealth of Australia

Philip Morris Limited (the applicant) sought a declaration that certain provisions of the Tobacco Advertising Prohibition Act 1992 (Cth) (the Act) were invalid. The respondent was the Commonwealth of Australia. The applicant argued that the Act, by prohibiting the advertising of tobacco products, infringed upon its freedom of political communication, a freedom implied in the Australian Constitution. The matter was heard by Dawson J of the High Court of Australia.

The central legal issue before the Court was whether the prohibition on tobacco advertising imposed by the Act impermissibly infringed the implied freedom of political communication. This required an examination of whether the prohibition was reasonably appropriate and adapted to serve a legitimate purpose in a manner compatible with the maintenance of the constitutionally prescribed system of representative and responsible government.

Dawson J found that the implied freedom of political communication does not extend to commercial speech, such as the advertising of tobacco products. His Honour reasoned that while the freedom protects communication about political or government matters, the primary purpose of tobacco advertising is to promote the sale of a product, not to engage in political discourse. Therefore, the prohibition on such advertising did not infringe the implied freedom. The Court concluded that the Act was a valid exercise of the Commonwealth's legislative power.
