PROBLEMATIKA UTUSAN KHUSUS PRESIDEN SEBAGAI LEMBAGA NON-STRUKTURAL DALAM SISTEM PEMERINTAHAN INDONESIANIM.: 24203011089Putri SantiauthorThis study discusses the problematic position of the Presidential Special Envoy as a non-structural institution in the Indonesian government system based on Presidential Regulation Number 137 of 2024. The existence of the Presidential Special Envoy as an apparatus formed by the President to carry out certain tasks outside the ministerial organization raises issues regarding the clarity of its institutional position, functions, and limits of authority in the Indonesian state system. This condition has the potential to cause overlapping tasks and authorities with ministries and other state institutions, thus raising questions regarding its compliance with the principles of limitation of power, the rule of law, and good governance. This study seeks to answer the formulation of the problem, namely how the Presidential Special Envoy stands as a non-structural institution in the Indonesian government system, and how the analysis of the principle of taḥdīd assulṭah relates to the position and clarity of the Presidential Special Envoy's function in the Indonesian government system. This research is a library research with a normative juridical approach. Primary data sources were obtained from Presidential Regulation Number 137 of 2024 and related laws and regulations, while secondary data came from books, scientific journals, articles, and relevant legal literature. This study uses the theory of state institutions and the principle of taḥdīd as-sulṭah as analytical tools in examining the position and function of the Presidential Special Envoy. Based on a systematic research framework, the study’s results include two conclusions as findings in the development of constitutional law scholarship. The first finding indicates that the poition of the President’s Special Envoy is an office established based on the President’s constitutional authority to carry out governmental functions; thus, it formally has a legitimate basis for its establishment. However, its regulatory framework still raises issues regarding the clarity of its institutional status, the limits of its authority, its functions, and its accountability mechanisms, thereby potentially leading to overlapping authority with ministries or other state institutions. The second finding indicates that, based on the principle of taḥdīd as-sulṭah, the establishment and administration of the office of the President’s Special Envoy must be grounded in the principles of the limitation of power, clarity in the division of authority, trust, justice, the public interest, and accountability. Therefore, regulations concerning the Presidential Special Envoy require a clearer formulation of functions, authorities, and accountability mechanisms to align with the principles of the rule of law, good governance, and Islamic legal values.342 Hukum Tata Negara2026-07-30UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS SYARI’AH DAN HUKUMThesis
