The European Integration and European Union’s Member States Sovereignty

European Union alike other international organizations rooted in an intergovernmental treaty in which member states limits their sovereignty powers in favour of that organization thereby given certain competences could achieved the common objectives. A particular trait of this structure is that the EEC/EU treaty has created its own legal system and is consequently capable of producing direct effects on the relations between member states and individuals. ECJ as authoritative interpreter of the community treaties following to this persuasive characterisation asserts principles of direct effect and supremacy of community law. Perhaps, it’s tends to introduce ‘Constitutionalism beyond the State’, i.e., EU constitutionalism. The German Federal Constitutional Court confirms sui generis nature of EU but it’s not willing to assuming a power which has not been conferred on it. Furthermore, it’s unlikely to FCC to endorse precise and indisputable supremacy of community law. The trend towards European unity oriented national sovereignty of member states is important and challenging issue that this article with descriptive and analytical approach by emphasis on the views of the German Constitutional Court has addressed.
