Vlastimir Djordjevic was indicted in October 2003 for war crimes and crimes against humanity committed in Kosovo in 1999. He was arrested in Montenegro in June 2007 after years on the run.
At an earlier appearance at the UN tribunal, Djordjevic refused to enter a plea.
It is not known yet when his trial will start. He faces a maximum sentence of life imprisonment if convicted.
