The purpose of this work is to examine whether common principles for judicial review of administration exist in the European legal area. Today, the law has been transforming into a form of internationalization in many areas of the world. This process is more visible in some fields of law in recent decades. In Europe, the law has become more intonational from the 1950s onwards; it is called as "Europeanization of law". Naturally, the administrative judiciary has not stayed out of this process. The author attempts to find common principles within the context of the Council of Europe and EU legal areas as well as French and British administrative judicial systems as two examples of European national jurisdictions by using a mixture of historical and comparative methods.
