(235 votes)

Indonesia's legal system is a complex tapestry woven from various sources, including customary law, religious law, and, most importantly, statutory law. This intricate system is governed by a hierarchical structure of regulations, each with its own distinct scope and authority. Understanding this hierarchy is crucial for navigating the legal landscape and ensuring compliance. This article delves into the sistematika dan hierarki peraturan perundang-undangan di Indonesia, providing a comprehensive overview of the structure and hierarchy of Indonesian legislation. #### The Foundation of Indonesian Legislation: The Constitution At the apex of the Indonesian legal system stands the Constitution, known as the Undang-Undang Dasar Negara Republik Indonesia Tahun 1945 (UUD 1945). This fundamental law serves as the bedrock of the entire legal framework, outlining the basic principles of governance, the rights and duties of citizens, and the structure of the state. The UUD 1945 is the supreme law of the land, and all other legislation must be consistent with its provisions. Any law that contradicts the Constitution is deemed invalid. #### The Hierarchy of Legislation: A Cascade of Authority Below the Constitution, a hierarchy of legislation unfolds, each level deriving its authority from the one above. This hierarchy ensures a clear chain of command and prevents conflicts between different laws. The primary levels of this hierarchy are: * Undang-Undang (UU): Laws enacted by the House of Representatives (DPR) and the President. These laws cover a wide range of subjects, from criminal law to economic regulations. * Peraturan Pemerintah (PP): Government regulations issued by the President based on the authority granted by a law. These regulations provide more detailed implementation of the laws. * Peraturan Menteri (Permen): Ministerial regulations issued by ministers based on the authority granted by a law or a government regulation. These regulations focus on specific areas within the minister's purview. * Peraturan Daerah (Perda): Regional regulations issued by provincial or district governments based on the authority granted by a law. These regulations address local issues and concerns. #### The Importance of Consistency and Harmony The hierarchical structure of Indonesian legislation emphasizes the importance of consistency and harmony between different levels of law. Lower-level regulations must be consistent with higher-level regulations. For example, a ministerial regulation cannot contradict a law, and a regional regulation cannot contradict a government regulation. This principle ensures that the legal system operates coherently and avoids conflicting interpretations. #### The Role of Judicial Review The Indonesian legal system also includes a mechanism for judicial review, which allows the Constitutional Court to review the constitutionality of laws and regulations. If the Constitutional Court finds a law or regulation to be unconstitutional, it can be declared invalid. This mechanism ensures that the legal system remains consistent with the fundamental principles enshrined in the Constitution. #### Conclusion The sistematika dan hierarki peraturan perundang-undangan di Indonesia is a complex but essential aspect of the country's legal system. This hierarchical structure ensures a clear chain of command, promotes consistency and harmony between different levels of law, and provides a mechanism for judicial review. Understanding this hierarchy is crucial for navigating the legal landscape, ensuring compliance, and upholding the rule of law in Indonesia.
