This paper explores the evolution of the experimental paradigm in legal frameworks, tracing its development from early influences in comparative law to the contemporary application of regulatory sandboxes. It begins with the integration of empirical methods inspired by scientific research into the field of law. The exploration covers various aspects of experimental law, including federalism, comparative law, legisprudence, emergency and incremental legislation, soft law, sunset legislation, temporary regulations, and experimental legislation stricto sensu. The paper concludes by discussing the challenges and implications of balancing experimental law’s flexibility with the need for legal stability and security.
