An important subject of bioethical and legal considerations is the relations and manifestations of what happens in current biomedical practice regarding the practice of activities and the provision of health care services. This is particularly important when it comes to disagreements, collisions, and conflicting rules, the ethical and legal origins of different norms, and medical decision making. An appropriate analytical and methodological approach through interpretation and comparison is needed to uncover shortcomings that often remain on the surface, invisible, due to the lack of dialogue. This paper aims to shed light on the fundamentals of bioethical principles on the one hand and the legal-logical system of norms in biomedicine on the other. The conclusion emphasises the elimination of the contradictory elements of the relationship and the affirmation of helpful and complementary aspects with the opening of parallel perspectives and intersections in the service of promoting the legality of the work, the development of good medical practice and respect for human rights in the field of health.
