This research aims to determine the legitimacy and explore the limitations of non-formal constitutional changes. This research uses normative legal methods with statutory, conceptual and case approaches. The results show that the legitimacy of non-formal constitutional changes is measured based on procedural legitimacy; that is, non-formal changes must be based on authority, and these changes do not affect the meaning of the Constitution as a whole. It is also measured based on substantial legitimacy; namely, non-formal changes to protect human rights. The limitation on changing the non-formal constitution is based on the main substance, which cannot be changed through non-formal changes such as constitutional structure, human rights, restrictions on authority and restrictions based on the moral constitution of the oath of office to implement and enforce the constitution. ## Keywords - Legitimacy - Constitutionalism - Constitution - Political science - Normative - Legislature - Law - Statutory interpretation - Law and economics - Statutory law - Separation of powers - Sociology - Democracy - Politics --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
