Abstract In the establishment of laws and regulations, the contents of the content material in statutory regulations must reflect legal certainty. Having regional legal products that are designed effectively and efficiently in health emergency situations is very important to provide legal certainty to the community and ensure that the response to the crisis is effective and in accordance with the broader legal framework. The research is a normative legal research. The researcher used a statutory approach and interviews. The data obtained was analyzed qualitatively. The results show that the establishment of regional legal products related to health emergencies in the aspect of legal certainty and usefulness, at least includes subsidiarity, hierarchy of norms, and legal certainty. Overall, this research demonstrates the important role of law in society, particularly in the context of health emergencies. In addition, it also shows how laws, both at the national and regional levels can work together to achieve common goals, protecting the health and welfare of society. Furthermore, this research also shows that the establishment of regional laws in the context of health emergencies is not only about overcoming the current crisis but also preparing the community and local government to face future health crises. In this case, law not only functions as a tool to regulate society, but also as a means to build community resilience and adaptability to public health challenges that may arise in the future.
