Abstract

How and to what degree do federations produce uniform law within their system? Our comparative empirical study addresses this question comprehensively for the first time by examining legal unification in twenty federal systems around the world. We present the means and methods of legal unification, the degree of legal unification of each system (and of particular areas of the law within each system), and a first attempt to explain the driving forces of legal unity and diversity in federations more generally.
