The document, called a memorial, was sent in electronic form to the Registry of the Arbitral Tribunal, established in accordance with the arbitration agreement signed by the governments of Croatia and Slovenia on November 4, 2009.

The 3,600-page document is divided into nine volumes. The main part is about 300 pages long and presents Croatia's position about the course of the maritime and land boundary and other issues at dispute between the two countries. The rest of the document relates to evidence and legal sources corroborating Croatia's position.

The memorial was signed by the Croatian government's representative before the Arbitral Tribunal, Maja Sersic, and the Assistant Minister of Foreign and European Affairs, Andreja Metelko Zgombic.

The parties to the dispute are to submit eight printed copies of their memorials to the Registry and 15 copies to the other party, according to the statement.

Simona Drenik, one of two representatives of Slovenia before the Arbitral Tribunal, said on Sunday that Slovenia would also send its memorial to the Tribunal on Monday, noting that its document was 5,200 pages long.

The Arbitral Tribunal has set February 11 as the deadline for the two parties to file their submissions specifying the course of the land border at the time when the two former Yugoslav republics declared independence. November 11 has been set as the deadline for the submission of counter-memorials.

The Arbitral Tribunal is chaired by Judge Gilbert Guillaume of France and its members are Professor Vaughan Lowe of the United Kingdom and Judge Bruno Simma of Germany. The Croatian government has appointed international law expert Budislav Vukas as Croatia's representative in the Tribunal, and Slovenia's representative is Jernej Sekolec.
