Taking Process-Based Theory Seriously: Could ‘Discrete and Insular Minorities’ Be Protected Under the Australian Constitution?

The High Court is committed to protecting the substantive rights necessary for the effective functioning of the constitutionally entrenched system of representative and responsible government. This is consistent with a ‘representation-reinforcing’ approach to constitutional review as advocated by John Hart Ely in the United States, in which judicial intervention is limited to protecting the ordinary political processes established by the Constitution rather than adjudicating on its outcomes. While the High Court has demonstrated an Elyian commitment to keeping open the channels of political change, it has not engaged with the protection of minority rights or equality concerns more broadly which were a key element of process-based theory. In this article, I argue that the judicial protection of minority rights is a necessary and desirable corollary of the constitutional entrenchment of representative government in the Australian Constitution. I explore how this could arise through either a freestanding guarantee of equality or in a weaker form by inflecting other areas of constitutional practice. Ultimately, I acknowledge that while the High Court’s current interpretive approach may not support a broad protection of equality, its process-based protection of representative government provides an available means to recognise minority rights under the Australian Constitution.
