The protest rally was held after the foundation of a Regional Cooperation Council at a summit of the Southeast Europe Cooperation Process (SEECP) in Zagreb on Friday. It was decided that the Council would have its headquarters in Sarajevo and that its secretary-general would be Croatian diplomat Hido Biscevic.
The party read out its request to the Constitutional Court to verify whether dozens of regional agreements Croatia had signed with its neighbours over the past few years were in compliance with the Croatian Constitution, considering the fact that Article 141 of the Constitution prohibits Croatia from joining any new Balkan associations.
The rally gathered about 100 people and passed without incident.
