Due to the existence of institutions such as Velayat-e Faqih (Guardianship of the Islamic Jurist) and the Guardian Council, the political structure of the Islamic Republic of Iran has introduced substantial modifications to the classical model of separation of powers. Consequently, the independence of each of the three branches of government—the legislative, executive, and judiciary—has been established only in relative terms, while overlaps and intersections of functions exist across various domains. Although this distinctive institutional structure has contributed to a certain degree of coordination and to the preservation of political cohesion within the system, it has, in some instances, resulted in constraints on the authority of elected institutions, reduced transparency, and greater difficulties in ensuring accountability. An analysis of the structural challenges confronting the principle of separation of powers in contemporary Iran may contribute to the identification of effective approaches for enhancing the efficiency and legitimacy of the country’s political system.</p> https://jlsda.com/index.php/lsda/article/download/528/441
