Abstract
This article focuses on the Treaty on Stability, Coordination and Governance in Economic and Monetary union (the so-called Fiscal Compact Treaty). It especially analyses the selected provisions of this international contract instrument and considers its impact on European primary law and the national law of Member States. In this respect, issues relating to reverse majority voting are examined, de facto the new kind of judicial control, the new obligations for Member States concerning the modification of their legal orders, which were not envisaged by the Foundation Treaties, etc. Other key problems addressed in the article are connected with the future “destiny” of the Fiscal Compact Treaty, including two different scenarios: a) the incorporation of its material scope into primary law or b) termination of the legal force of this act after the expiration of a certain period of time.
