This article considers the effects of special constitutional prerogatives for Buddhism in Sri Lanka. It argues that, contrary to the expectations of both supporters and opponents, these clauses have not done what they claim to do: they have not enhanced the dominance of Buddhism on the island. Through a detailed analysis of recent legal action, this article demonstrates how special constitutional protections for Buddhism, in fact, aggravate and authorize splits among Buddhists. In making this argument, this article points towards a larger thesis: constitutional provisions designed to ensure the inter-religious dominance of one tradition may, under certain circumstances, actually amplify intra-religious conflicts over the nature, boundaries, and doctrines of that tradition. This work therefore encourages scholars to rethink the assumed polarity between secular-liberal constitutions and religiously preferential ones. Although opposed in their expressive dimensions, religiously neutral and religiously preferential constitutions may in fact generate similar church-state conundrums. The case of Sri Lanka suggests that, in the same way as perfect religious neutrality is impossible, so too is perfect religious supremacy.
