This article looks at the Acehnese government, which is one of Indonesia's special autonomous provinces, through the lens of nomocracy, or the supremacy of law. A hallmark of a nomocratic administration is its adherence to the rule of law and its reverence for individual liberties. Nomocracy, according to this study, is an essential component of effective governance since it increases the legitimacy, accountability, and responsiveness of government. In addition to examining Aceh's political, cultural, and historical setting, this article examines the ways in which Aceh's past impacts its present-day administration. Aceh has fiercely resisted outside influence throughout its history, first from the Dutch colonizers and subsequently from the Indonesian government. There is a lot of oil and gas in Aceh, which causes disputes and divides the profits. As part of a peace accord that ended the decades-long military confrontation between the Central Government and the Free Aceh Movement (GAM), Aceh was awarded special autonomous status in 2001. When it comes to matters of faith, education, culture, and justice, for example, Aceh enjoys more power thanks to its special autonomy. More civil society involvement, more openness and accountability, and peaceful conflict resolution are just a few of the suggestions made in this report to improve Aceh's nomocracy and government.
