This research aims to analyze the legal framework that regulates the authority of law enforcement agencies in coastal and marine areas and formulate an ideal model of authority oriented towards fair governance. The problems studied include: (1) how the structure of the legal framework that regulates the authority of law enforcement agencies in coastal and marine areas and its limitations in ensuring justice; and (2) how to reformulate the authority of these institutions in order to be able to realize justice-oriented law enforcement governance. This study uses a Sociological juridical method with an analytical descriptive approach. The theoretical approaches used include justice theory, legal system theory, and authority theory in state administrative law. The results of the study show that: 1) The legal framework that currently regulates the authority of law enforcement agencies in coastal and marine areas is still sectoral, fragmented, and has not been systematically integrated. This condition is reflected in the overlap of authority between institutions, disharmonization of regulations, and weak coordination in the implementation of law enforcement. Normatively, regulations are available, but they have not been accompanied by an integrated institutional design and a legal culture that supports collaboration. As a result, law enforcement in coastal and marine areas has not been able to provide legal certainty and substantive justice, especially for coastal communities who are vulnerable to inequality of access and legal protection. 2) The reformulation of the authority of law enforcement agencies in coastal and marine areas must be carried out comprehensively with an integrative approach that combines justice theory, legal system theory, and authority theory in administrative law. In the perspective of John Rawls's theory of justice, such reformulation must ensure a fair and proportionate distribution of authority and provide protection for vulnerable groups. Meanwhile, from the perspective of the theory of administrative authority developed by Philipus M. Hadjon, the division of authority must be based on the principle of legality through clear mechanisms of attribution, delegation, and mandate. Thus, the reformulation of authority must include harmonizing regulations, strengthening institutional structures, and building a collaborative and accountable legal culture.
