States embracing Islam-based laws are frequently seen as struggling with establishing democratic institutions, jeopardizing human rights and encouraging executive encroachment on the judiciary. This paper explores whether the presence of Islam-based legal language in a domestic legal system is associated with lower levels of electoral democracy, fewer protections for private liberties, women’s rights, and a weak judiciary. Relying on original data covering laws in 29 Islamic law states (2001–2012), we focus on Islam-based legal language in these states’ constitutional and subconstitutional domestic legal systems. By itself, Islam-based legal language is not associated with a weak judiciary or the absence of political liberties. However, subconstitutional—particularly legislative—commitments to Islam-based legal language are frequently associated with lower levels of democracy and fewer protections for private liberties and women’s rights.
