One of the Slovenia's agents at the court, Simona Drenik, told the STA that the Slovenian side had done a very good job and that the "baton is now in the hands of the arbiters".

The five-strong arbitration tribunal - chair Gilbert Guillame and members Vaughan Lowe, Bruno Simma, Jernej Sekolec and Budislav Vukas - will now withdraw to deliberate and a decision is expected within a year.

The final decision will demand a simple majority, which means that three out of five tribunal members must support it.

The tribunal may also decide to visit the problematic segments of the border before making a decision, but Drenik indicated this seemed unlikely.

Drenik was unable to disclose any of the content from the sessions that took place behind closed doors and explained that "despite the wish and effort to have the arbitration court publish a press release okayed by both sides already today...the decision was made that the report be released on Monday afternoon".
