This book includes case studies of a number of systems from across the globe and explores the manner in which the elements of these mixed systems may be seen to be ‘entrenched’, ‘endangered’, or ‘blended’. The studies involve consideration of the colourful histories of the jurisdictions, of their complex relationships to parent legal systems and traditions, and of language, legal education and legal actors. They explore how the process of legal change happens, questions whether some systems are at greater risk than others, and details the strategies that have been adopted to accelerate or counteract change.
