The European Union is based on four fundamental freedoms: the free movement of goods, the free movement of people, the free movement of services, and the free movement of capital. These freedoms are crucial for the functioning of the EU's internal single market and the integration of Member States, and they ensure economic growth and cooperation within the EU. Therefore, it is not surprising that the Union needs to legally regulate potential disputes arising between legal entities from different Member States in their cross-border cooperation. The most important source for international jurisdiction in consumer contracts is Regulation Brussels I bis (REGULATION (EU) No 1215/2012 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 12 December 2012 on jurisdiction, recognition, and enforcement of judgments in civil and commercial matters), while the applicable law is governed by Regulation Rome I (REGULATION (EC) No 593/2008 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 17 June 2008 on the law applicable to contractual obligations), which will be the primary focus of this work. To achieve effective consumer protection, it is necessary to interpret these two Regulations consistently, supported by the practice of the Court of Justice of the European Union. We will explore why these Regulations are important for consumer protection and analyze how this protection is applied through various European Court of Justice judgments.
