Přednost práva EU ve vztahu k vnitrostátním právním řádům členských států

This thesis is concerned with primacy of European law in relation to national law of EU member states. The goal is to investigate, to what extent does European law have primacy in relation to national law of member states, and in particular their constitutional law. This is achieved by specifying the concept of primacy of EU law by looking at the practice of the Court of justice the European union and constitutional courts of member states that deal with primacy of EU law. This work also aims to look at the impacts of a national act that is incompatible with EU law. Furthermore, it attempts to answer to what extent does the protection of basic rights guaranteed by constitutions of member states affects the principle of primacy by looking at the practice of the courts of EU member states.
