Sanader was commenting on the decision of the International Criminal Tribunal for the former Yugoslavia (ICTY) of Wednesday to turn down Croatia's request to be given amicus curiae status in the trial of the three generals.
Asked if the government would appeal against the decision, Sanader said that the Council for Cooperation with the ICTY would discuss this matter soon.
ICTY judges turned down Croatia's request to be given "friend of the court" status in the trial of Gotovina, Markac and Cermak, explaining that the status of amicus curiae was generally granted to help the tribunal clarify legal questions while Croatia, they said, was trying to influence cases which referred exclusively to the establishment of facts.
The ICTY said that Croatia's request referred mostly to the establishment of facts and recalled that under ICTY rules, the presentation of facts was within the jurisdiction of the parties in the proceedings, and not of friends of the court.
The ICTY also said that most facts Croatia wanted to tackle were too broad in relation to the indictment and that to consider them would not be of help to the Trial Chamber conducting the case.
The judges further said that if Croatia was in possession of any information relevant to the proceedings, it could submit it to either party in the proceedings.
