Abstract
Abstract.The enactment of Law Number 1 of 2023 concerning the Criminal Code (the New Criminal Code) brings a fundamental repositioning to the national criminal law system, particularly through the recognition of the material legality principle that accommodates the living law in society under Article 2. On one hand, this approach represents a form of legal decolonization; however, on the other hand, it triggers a paradigmatic tension between legal positivism in Article 1 and the sociological jurisprudence in Article 2. This article analyzes the existence and dialectics of these two articles using a dogmatic legal framework that balances protective functions and integrative criminal law paradigms. The research method employed is normative legal research with conceptual and statutory approaches. This article offers a novelty in the form of a conceptual synthesis regarding the process of "positivization of customary law" through Local Regulation (Perda) instruments, as well as a dogmatic analysis of measuring fault (mens rea) in customary offenses. The research findings indicate that Article 2 paragraph (2) of the New Criminal Code functions as a constitutional anchor that compels customary law to submit to the pillars of lex scripta and lex certa of Article 1, thereby preventing overcriminalization and judicial subjectivity.
