This study contains analysis of the relationship between the European Union law and the international public law in the spirit of the founding treaties of the European Union, combined with analysis of selected jurisprudence of the Court of Justice of the European Union in the field of relationship of the international public law and the European Union law. In the context of these analyses, the relationship between the European Union environmental law and the international environmental law as specific, newly emerging sectors of both systems of law can also be elucidated. Given the existing interactions between the European Union law and the international public law, we consider these analyses to be scientifically useful which will allow us to identify the key elements of the relationship between the two sectors of law in conclusions of the study and thus help the process of their smooth application in legal practice.
