This research deals lucidly and objectively with the possibility of applying the epistemological practice of transdisciplinarity to the science of law, as well as developing a transdisciplinary curriculum in law. To this end, it first presents some characteristics of transdisciplinary thinking, highlighting the complexity and development of transdisciplinary research (as compared to disciplinary, interdisciplinary and multidisciplinary research), which can be more easily addressed in law. It then presents Thomas Kuhn’s thoughts on the evolution of the sciences, highlighting scientific revolutions, the process by which one paradigm succeeds another ─ a model that inspires the idea of transdisciplinarity in law. All this is accompanied by numerous examples. He also analyzes some national regulations in Brazil and Romania, such as Resolution CNE/CES No. 5 and Resolution No. 75 of the National Council of Justice, identifying the forums of transdisciplinarity in the provisions of these documents (which set guidelines for law). Finally, it identifies legal positivism as a paradigm of legal science and presents some of its limitations in the face of transdisciplinarity and the evolution of social phenomena (characterising its crisis), giving the example of international law, in which context it is proposed to challenge the transdisciplinarity of law.
