This groundbreaking volume of The ANNALS provides the first overview of class action laws and related mechanisms around the world. It features 30 country reports by leading scholars, describing the adoption, characteristics and consequences to date of class action and non-class group litigation procedures ranging across North and Latin America, Australia, Asia and Europe. In December 2007, Stanford Law School and the Oxford Centre for Socio-Legal Studies organized an international conference that studied the global spread of class actions and group litigation procedures. Scholars, jurists, and practitioners from around the world gathered to discuss and debate the use of group litigation procedures and initiate a research project on the evolution of class actions and aggregate litigation worldwide. This volume of The ANNALS is one result of that conference. Students, scholars and policymakers will find this anthology of reports to be an essential overview, providing a solid understanding of the effects of class actions around the globe.
