Advocate General Priit Pikamäe proposes the Court of Justice of the European Union (CJEU) to declare that it does not have jurisdiction to hear an action brought by Slovenia, who submits that Croatia is preventing it from fully exercising its sovereignty throughout its maritime territory. The Advocate General is of the view that the delimitation of national territory does not fall within the sphere of competence of the European Union or of the CJEU (CJEU press release of 11 December 2019).
Both parties submitted a territorial and maritime boundary dispute to the Permanent Court of Arbitration (PCA), who issued a Final Award determining the creation of a “Junction Area” and setting the terms of the special regime to apply therein. The PCA emphasized that this special regime is intended to guarantee both the integrity of Croatia’s territorial sea and Slovenia’s freedoms of communication between its territory and the high seas (PCA press release of 29 June 2017). Croatia decided to withdraw from the 2009 Arbitration Agreement in 29 July 2015 and later stated that this award “does not in any way bind Croatia and Croatia shall not implement it” (Croatia Ministry of Foreign and European Affairs press release of 29 June 2017).
In its action brought to the CJEU (2018/C 399/27) on 13 July 2018, Slovenia argues that Croatia “unilaterally refuses to fulfil its obligations under the arbitration award”, namely in “denying Slovenian fishing vessels free access to the marine waters which the arbitration award of 2017 has defined as Slovene, and, a fortiori, free access to Croatian waters falling within the scope of the mutual access regime”.
