Margetic is charged with disclosing the names of 102 protected witnesses on his personal website (www.domagojmargetic.com) from July 7 to August 2 this year. All the witnesses testified in the case against Bosnian Croat wartime military commander Tihomir Blaskic.
The presiding judge said that the trial would take place in mid-November and that it would last only one day, when both the prosecution and the defence would present their cases.
If found guilty, Margetic faces a prison sentence of up to seven years or a fine not exceeding 100,000 euros.
