Brown v Tasmania (2017) 261 CLR 328
The Tasmanian Parliament enacted the Workplaces (Protection from Protesters) Act 2014 (Tas), which created offences for entering or remaining on business premises and for impeding or obstructing business activities. Bob Brown and Jessica Hoyt were charged under the Act after participating in a protest in a forestry coupe in Tasmania. They challenged the validity of the Act on the ground that it burdened the implied freedom of political communication under the Commonwealth Constitution.
1. Whether the Workplaces (Protection from Protesters) Act 2014 (Tas) burdened the implied freedom of political communication. 2. Whether, if such a burden existed, the Act was compatible with the constitutionally prescribed system of representative and responsible government, applying the proportionality test established in McCloy v New South Wales.
The High Court held, by majority, that the Workplaces (Protection from Protesters) Act 2014 (Tas) was invalid because it imposed an unjustified burden on the implied freedom of political communication and was therefore inconsistent with the Commonwealth Constitution.
A State law that burdens political communication — including non-verbal conduct conveying a political message — is invalid under the implied freedom if it is not reasonably appropriate and adapted (proportionate) to serve a legitimate purpose compatible with the constitutionally prescribed system of representative and responsible government; the court must assess whether the law is suitable, necessary, and adequate in its balance between the legislative object and the extent of the burden imposed on political communication.
Members of the majority made significant observations about the application and structure of the proportionality test derived from McCloy, including whether 'adequate in its balance' operates as a distinct third limb of the test; Gageler J, in a separate concurrence, expressed reservations about adopting a structured proportionality framework derived from German and Canadian jurisprudence and preferred a more direct inquiry into whether the law was reasonably appropriate and adapted to a legitimate end.
Brown v Tasmania confirmed that the implied freedom of political communication extends to protect expressive conduct, not merely speech, and entrenched the structured proportionality test from McCloy v New South Wales as the operative framework for assessing the constitutional validity of laws burdening political communication, significantly constraining the capacity of Australian legislatures to criminalise protest activity.
