International and Foreign Law in Domestic Constitutional Law

This chapter illustrates the role of international and foreign law in domestic constitutional law. Through the case analysis of South Africa (a post conflict state) and the United States (often seen as a country that is not too friendly to international and foreign legal systems), it discusses the role of international and foreign law in reconciling the regional development of the rule of law in a country, by working closely together with domestic constitutional law. The domestic courts both in the United States and South Africa, whenever they deem it appropriate, do consider international and foreign law in the resolution of disputes before them. The conditions under which each jurisdiction may resort to foreign or international law, as well as the criteria used for taking them into consideration, vary. However, most importantly, this practice should be encouraged as it promotes the uniform interpretation of international law and the progressive advancement of norms world-wide, which are aspects that are especially important in the field of human rights.
