PANCASILA SEBAGAI GRUNDNORM MENURUT TEORI HUKUM MURNI HANS KELSEN DAN TEORI HUKUM RESPONSIF OLEH PHILIPPE NONET DAN PHILIP SELZNICK

This study discusses the role of the state foundation, responsive legal theory, and the philosophical values ​​of Pancasila in developing a relevant and quality legal system. Using a qualitative approach, this study synthesizes Hans Kelsen's "grundnorm" theory and Philippe Nonet's and Philip Selznick's responsive legal concepts. Kelsen emphasized the importance of a stable legal hierarchy for legal legitimacy, while responsive legal theory highlights the flexibility of law in dealing with social dynamics. The results of the study indicate that Pancasila functions as a "grundnorm" in the Indonesian legal system, providing a moral, cultural, and philosophical basis for creating justice and prosperity. The integration of Pancasila values ​​with a structural and responsive approach produces an inclusive, adaptive, and sustainable legal system. It can be concluded that the combination of the state foundation, responsive law, and philosophical values ​​allows for a legal system that is responsive to social change without losing its legitimacy and basic principles.
