摘要:The types and hierarchies of laws and regulations are constantly changing. Law Number 12 of 2011, as amended by Law Number 15 of 2019, leads to several problems. This research aims to analyse Indonesia's laws and regulations regarding their types and material contents. This is normative legal research employing statutory, historical, and conceptual approaches. The findings of this study are as follows. First, TAP MPR should not be classified into laws and regulations as stipulated by Law Number 12 of 2011, as MPR can no longer issue any regulations after the amendment of the 1945 Constitution. Another problem lies in the absence of review if laws and regulations deviate from TAP MPR. Second, it is essential to restrict Perppu, particularly when issuing it. The President can issue Perppu at will, for there is no definition of compelling exigencies. It should merely be issued during the recess periods of DPR. Third, there is no difference between Government Regulations and Presidential Government content. Fourth, other regulations, especially Permen, prove problematic due to the silo mentality, so that they conflict with each other and even overlap higher regulations
