Listing the arbitration agreement, Slovenian fences on the border with Croatia, the defunct LB bank, as the key open issues, the paper says that the Croatian minister came to Ljubljana "as on a field trip and completely unprepared" with regards to the arbitration, which he labelled as passe.

"To be completely honest, this is not entirely true, he pulled out Slovenia's land register to prove that the country's fences were on Croatia's land."

However, why stick to the land register at one point and not at the other, which shows Slovenia's territory on the left side of the Dragonja river, which Croatia deems is a part of the southern country, the paper wonders in Passe.

"Such turnovers by Croatian politicians...is conduct that should be considered passe for an EU and NATO member. Like the Slovenian parliament playing around with the arbitration decision," the commentator concludes.
