Race, religion and royalty (the Three ‘Rs’) have been salient aspects of Malaysia’s constitutional struggle. These elements have defined the country’s constitutional settlements during the pre-independence constitution-making process, generated constitutional crises and continued to figure into day-to-day governance and constitutional practice. There have been instances where operation of and compromises around the Three Rs have facilitated constitution-building. Yet, more often than not, as this article illustrates, the constellation of these three forces have challenged the building and sustaining of a constitutional democracy. Since the historic political change in May 2018 in particular, the Three Rs have become even more significant in shaping the critical junctures in Malaysia’s constitutional journey. To illuminate a more comprehensive understanding of the role of race, religion and royalty in Malaysia’s struggle for constitutional democracy, this article explains how these elements have defined (and continued to define) controversies relating to the distribution of political power and the protection of fundamental rights. Fundamentally, these aspects implicate checks and balances and constraints on political power. This article also demonstrates the ways in which the struggle for constitutional democracy implicates a range of actors and interests: aside from individual citizens, there are the monarchy, the elected government, the courts and group (ethnic) interests. This article then draws on institutional and political explanations in accounting for Malaysia’s constitutional struggle. In particular, aside from changing political fundamentals, it argues that the Constitution provides the opportunity structure and institutional resources for the Three Rs to shape Malaysia's struggle for constitutional democracy.
