Abstract
This study examines the legal implications of land registration service restrictions imposed in the Nusantara Capital City (IKN) region, with a particular focus on the protection of citizens’ constitutional rights as guaranteed under the 1945 Constitution of the Republic of Indonesia. The moratorium on land registration services in the IKN area, enacted through various government regulations and ministerial decrees, has created legal uncertainty for local communities who have long occupied and cultivated land in the region. This research employs a normative juridical method with a statutory approach, conceptual approach, and comparative approach, analyzing primary and secondary legal materials. The findings reveal that the service restrictions create a tension between state authority over land development for the national capital and the constitutional rights of citizens to legal certainty, property rights, and equal treatment before the law. The study concludes that while the government holds legitimate authority to regulate land in the IKN area, the blanket restriction on registration services without adequate legal remedies for affected citizens constitutes a potential violation of constitutional rights. Recommendations are made for a balanced regulatory framework that accommodates both national development interests and the protection of individual constitutional rights.
