Domestic Constitutional Oversight and International Courts

Does a domestic constitutional court within a state encourage greater acceptance of the jurisdiction of the International Court of Justice (ICJ)? This question is particularly relevant in Islamic law states (ILS). One might expect that ILS, which embrace the rule of law domestically, might do so internationally. However, this expectation paints an overly simplistic picture of the constitutional court’s role and its relationship with domestic and international politics. Employing original data on constitutional references to constitutional courts (1946–2012), we show that in the context of ILS, acceptance of the ICJ’s jurisdiction is conditional on an independent constitutional court.
