The topic of Wali Nanggroe makes an original a contribution to knowledge, as this information is not published globally. The discussion of Wali Nanggroe in the legal system of Aceh, Indonesia is a critical debate. Recently, the existence of Wali Nanggroe in the kingdom period of Aceh has been disputed. This article critically discusses the legal norms established by the by-laws of Wali Nanggroe. The by-laws relate closely to the electoral mechanism of the candidacy of Wali Nanggroe in Aceh. The research approach used here is normative juridical, through legal, comparative and historical principles. Data analysis was carried out by qualitative analysis. The selection of the nanggroe guardian based on Qanun No. 8 of 2012, in Article 70 is inconsistent with the principle of legal justice because it lacks the regulation of mechanisms for democratic people’s involvement. The determination of the nanggroe guardian election model stipulated in the qanun is contrary to the principle of the rule of law and the sovereignty of the people. According to the principle of justice, nanggroe guardians in Aceh must be democratically chosen by involving all Acehnese people. The main function of the presence of the nanggroe Aceh guardian is to unite existing ethnic groups and ethnic groups in life to sustain its customs and unite the community. The election of the nanggroe guardians should therefore involve all levels of Acehnese society. For this reason, it is important to avoid any perception that the nanggroe guardians only belong to certain groups. The nanggroe guardian needs to truly belong to all Acehnese people and the role should be strengthened by means of deliberation.
