Uncovering cases of unnatural death is crucial for the purpose of law enforcement. However, the investigation of these cases often faces challenges, particularly when it comes to obtaining information about the causes and circumstances of death, which can be revealed through forensic autopsies based on medical principles. Unfortunately, the rejection of forensic autopsies by the victims' families poses a significant obstacle. This research aims to explore and analyze the legal implications that arise from the family's refusal of a forensic autopsy, with the ultimate goal of ensuring effective law enforcement against families who reject such procedures. Additionally, the study seeks to find solutions for conducting forensic autopsies in order to uncover the material truth behind criminal cases involving unnatural deaths. The research adopts a normative juridical approach, focusing on examining theories, concepts, legal principles, and relevant laws and regulations. Secondary legal materials are analyzed qualitatively through library research techniques. The findings of this study underscore the need for comprehensive legal reforms that address the implementation of forensic autopsies in cases of unnatural deaths, in order to facilitate the pursuit of material truth.
