What normative principles should multicultural states be guided by in responding to minority claims for the accommodation of cultural and religious social practices? This article explores how theories of non-domination can contribute to debates on this question in the multiculturalism literature. It examines Philip Pettit's, Cecile Laborde's and Frank Lovett's republican theories and argues that non-domination-based approaches to multicultural accommodation are more suitable to assess the dynamic of intra- and inter-group relations than the prominent liberal-multiculturalist alternative. However, their advantages are not contingent on the wider theories from which they emerge, but rather related to generalizable features of the non-domination ideal. This suggests that non-domination should also be appealing to non-republicans, who can adopt it minimally as a critical principle to determine illegitimate policies.
