This book defines the characteristics of a new discipline that is both legal and scientific: user-friendly legal science.Focusing on how legal tools and practices can be used to achieve objectives in different contexts, it offers an alternative to doctrinal research, law-and-something disciplines, and the traditional interdisciplinary approach.The book not only defines the new discipline’s research approach, point of view, theory-building, and research methods, it also shows how it relates to other scientific disciplines and how existing doctrinal legal disciplines can be upgraded into scientific disciplines.
