What forms of accommodation ought to be extended to religious institutions? Should churches, firms, charities and schools with a religious ethos be permitted to discriminate in ways that would otherwise be illegal? Should they be allowed to opt-out of particular laws so as to enable them to preserve their distinctive characters? This article addresses these questions by defending three claims. First, legal exemptions for religious institutions can potentially be justified by combining two principles: freedom of association and freedom of religion. Second, such exemptions potentially leave members vulnerable to domination. Third, individual non-domination and institutional autonomy can be reconciled under a regime of joint governance.
