The countries covered are the United States, Norway, Belgium and France; all countries having an old constitution. The following questions are dealt with: the emergence of judicial review of national legislation, the interpretation of old constitutional texts, complementary sources to old constitutional texts, the application of old constitutions in modern societies, and the legitimacy of judicial review of legislation.
