The constitutionality of the EU secondary law in the Visegrad Group's countries

The Visegrad Group's countries joined the European Union more than 10 years ago, it's a long time, enough to take in trying to assess the functioning of theacts created by the European Union in the constitutional courts of the new Member States. Due to the similarity of cultural, historical and legality seems to be useful toanalyzethe legal situationin Poland, the Czech Republic, Slovakia and Hungary. The study shows that the constitution in so far as they relate to theacts of secondary EU law in the national legal system may raise some confusion. In Poland and Slovakia the constitutions guarantee the primacy of the EU secondary law, however, they do not precise there lation ship between those acts and the EU secondary law. In the Czech Republic the constitution does not relate to the acts created by the European Union. In Hungary, in turn, EU law is treated as anational law, but it does not eliminate the doubts about the possibility of its control with the constitution.
