Article is dedicated to the problems of preparation and formation of the amendment of the Constitution of the Czech Republic No. 395/2001 Sb. (Coll.), which is branded a "euro-amendment" of the Constitution of the CR. Essence of this amendment of the Constitution of the CR was comprehensive embedding and position of international treaties in the Czech legal system.
One particular category of international treaties on human rights and fundamental freedoms was abolished and new unified conditions were created, by meeting of which an international treaty becomes a part of the legal system with application priority before a law. Main focus of this article are the problems of international treaties on integration by the article 10a of the Constitution of the CR, through the power of which some of the authority of the bodies of the CR are transferred to an international organization or institution.
International treaties on integration are very difficult to classify. The key question is, when the transfer of authority to an international organization occurs and whether a constitution maker is able to identify this moment at all.
The problem of interpretation of international treaties by the article 10a of the Constitution of the CR consists of a question whether, during their ratification, one should follow a purely formal procedure in accordance with the principle of procedural equivalence, or whether one should judge each particular international treaty, albeit mostly only on purely hypothetical level, to find out whether it constitutes a transfer of authority or a change of conditions for execution of authority, which the Czech Republic already has transferred to an international organization. The article also presents a comparative overview on what way the international treaties on integration are adopted in individual member states of the European Union.
