With the worldwide development and expansion of constitutional courts and councils, the importance of constitutional jurisprudence has naturally increased in recent decades throughout the world.
Dr. Sleiman argues that without the existence of constitutional jurisdictions, the development of constitutional jurisprudence would be left in the hands of political actors governed by political and fluctuating considerations, rather than by the supreme national interest.
As the European example shows, constitutional jurisprudence is particularly abundant in federal states as it plays a crucial role in preventing conflicts between regional laws and the federal constitution. At the same time, constitutional jurisprudence has in many countries been increasingly influenced by the creation and development of supranational entities and the proliferation of regional and international legislation.
