Constitutional review, as a mechanism to guarantee the supremacy of the Constitution in the hierarchy of legal norms, has two principal functions: to review the legislative enactments in terms of non-compliance with Constitution and Sharia, and to settle the conflicts among public entities. Nevertheless, due to lack of institutional structure regarding the second function, this subject has not been so much discussed by the Iranian public law scholars. But, it seems, after the establishment of a relatively newfound entity in the legal system of the Islamic Republic of Iran, namely the High Committee for Resolving Disputes and Coordinating Relations among Triple Powers according to Article 110 (7) of the Constitution, it is time to much more focus on such function. Since, the foresaid Committee has no function except to settle the conflicts regarding the competences, this article, through an analytic and comparative method, recognizes the function of the Committee in the position of Constitutional review. Besides, this article examines the evolution of the dispute resolution mechanism in the Islamic Republic of Iran and compares legal nature and current competences of the Committee with similar entities in other countries. Finally, transforming such Committee to a Constitutional entity is considered in the revision of the Constitution.
