The main objective of this study is to present a comparative legal analysis of proportionality. It provides a close examination of the key areas in which this principle has been applied, both at the national and supranational levels. The whole work is placed in the context of transformation of public law in the twentieth century.

As many important general principles of law as applied by the Court of Justice have been borrowed from German and French law, a comparative study of the various forms which this principle has assumed in both German and French public law is presented. The book then offers an in-depth analysis of the application and impact of the principle of proportionality in EC law.

The introduction and development of this principle by the Court of Justice represents one of the most striking examples of the interaction between the Community and national legal systems. It also illustrates the character of Community law as developed by the Court and the law-making function of the latter.
