Scholars have shown that integration into the international human rights regime leads countries to exercise greater respect for domestic human rights (e.g. Landman 2005). Particularly, the international human rights covenants that member countries enter into are pivotal to the domestic protection of human rights. However, the effectiveness of these covenants varies significantly within the regimeâs member countries. One explanation of these variations provided by scholars focuses on the low capacity of the regime to monitor and enforce these covenants (e.g. Bayefsky 2001). Few studies, however, examine the effect of domestic institutional factors on the implementation of human rights covenants. In this study, we provide important insight into the protection of human rights by examining the role of domestic institutions, specifically constitutional provisions, in the enforcement of international human rights covenants. Using the Comparative Constitutions Project (forthcoming), we conduct a large-N, cross-national analysis of the most recent constitutions of the independent countries on Ward and Gleditsch's (1999) list. We test the effect of constitutionally established treaty supremacy, separation of powers, judicial independence and judicial review, and the interaction of these provisions on the enforcement of human rights covenants and respect for human rights (data derives from Landman (2005) and CIRI Human Rights Dataset (2004)). We argue the adoption of constitutions granting foreign treaties supremacy over legislative and constitutional law, separating treaty making and reviewing power, and providing for independent judiciaries with the power of judicial review lead to better enforcement of human rights covenants and thus greater respect for human rights. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]
