This study aims to identify the policy formulation in Law No. 36 of 2009 on Health regarding abortion for fetal defects and the necessary formulation of the law to achieve legal certainty. The research method used was a literature review by analyzing legal documents and relevant literature on the issue. The analysis showed that Law No. 36 of 2009 on Health limits abortion for fetal defects to be performed only before the pregnancy reaches 6 weeks, while fetal defects usually can only be detected after 16 weeks. This causes legal uncertainty for doctors and patients. Therefore, policy formulation is needed that considers medical and moral factors to achieve legal certainty in the practice of abortion for fetal defects.
