Adverse events that can lead to damage (destruction of) to the sea and the marine environment are common in maritime navigation. Such private law situations have, as a rule, an international and / or cross-border character, and therefore there is a high possibility of a dispute with an international character. Tort pollution must be distinguished from the (more common and destructive illegal repercussions) usual (standard) harmful unlawful consequences. In order to ensure adequate compensation for victims of pollution, there should be an appropriate legal framework for civil liability for damage resulting from (coused by) maritime activities. The paper presents (discusses) the process of unification (unification) of maritime law in the field of maritime offenses. The provisions on the applicable law for non-contractual liability for environmental damage in maritime navigation are then analyzed (examined). The Rome II Regulation unifies the conflict-of-law rules for non-contractual liability for damages within the EU, and its solutions are directly applicable in Croatian private international law after the accession of the Republic of Croatia to the EU. An overview of this source of European international tort law contained in the secondary law of the European Union (Rome II Regulation) is given. (Mentioned article provides an overview of this source of European international tort law found in the European Union's secondary law (Rome II Regulation)) Furthermore, the most important links are analyzed, and special attention is paid to determining the environmental damage embodied in Ar. 7. Regulations Rome II. (In addition, the most relevant links are examined, with special emphasis paid to determining the environmental harm inherent in Article 7 of the Rome II Regulations.)
