What did the Arbitral Tribunal determine?
In the Final Award the Arbitral Tribunal determined the course of the entire land boundary between Slovenia and Croatia.
In accordance with the Arbitration Agreement, in delimiting the land border, the Tribunal applied international law and, within this framework, the principle of uti possidetis, which after the break-up of a country allows for the conversion of former administrative borders into international borders.
The Tribunal also determined the maritime boundary between the two countries, which had never been delimited before.
In this the Tribunal applied international law, as set out by the Arbitration Agreement. The Bay of Piran retained the status of internal waters and the border in the Bay was determined in accordance with the principle of uti possidetis.
The border between the territorial seas of Slovenia and Croatia is a modified equidistance line.
The Arbitral Tribunal determined Slovenia's junction to the high seas.
In doing so, it applied international law, equity and the principle of good neighbourly relations in order to reach a fair and just decision, taking into account all relevant circumstances.
It determined the junction to be the area that connects Slovenia’s territorial sea to the high seas. In the junction area there is freedom of communication for all ships and aircraft, equally and without discrimination on grounds of nationality, for the purpose of access to and from Slovenia.
