Arguably, the most important element in any system of economic integration is the freedom of movement of persons. In this as in other initiatives, the European Community has taken the lead, and emerging economic unions and common markets elsewhere in the world take full cognizance of the EC's successes and failures as this fundamental right has developed under European law. The present volume provides a comprehensive overview of this body of law, encompassing doctrinal basis, institutional framework, legal compliance, judicial development, and derogation on such grounds as security and health. In addition to providing analysis of the relevant provisions of the European Community Treaty as amended by subsequent treaties including the Treaties of Amsterdam and Nice, the book takes considerable account of all relevant secondary legislation and sometimes soft law, for example draft treaties, resolutions, and draft legislation. The authors also consider what obstacles remain to this freedom, and what future developments might take place in this area of Community law.
