Prosecutors acknowledged that the error "could impact on the fairness of the trial to the accused," Jelacic said.
The tribunal published a letter Thursday from prosecutors to Mladic's lawyer that explained the missing documents were not uploaded onto an electronic database accessible to defense lawyers. "We sincerely apologize for the inconvenience that these missing materials ... may have caused to you," the May 11 letter says.
Earlier Thursday, prosecutors wrapped up their opening statement in the trial by recounting in painstaking and chilling detail the systematic murder by Bosnian Serb forces commanded by Mladic of thousands of Muslim men and boys in Bosnia's Srebrenica enclave in July 1995, Europe's worst massacre since World War II.
"In a period of only five days, from July 12-16, 1995, the armed forces of [Bosnian Serb leader] Radovan Karadzic and Ratko Mladic expelled the civilian population of Srebrenica and murdered over 7,000 Srebrenica men and boys," prosecutor Peter McCloskey said. Other estimates range up to 8,000 dead.
Mladic's army "carried out their murderous orders with ... dedication and military efficiency," he added.
Mladic, the 70-year-old former commander of the Bosnian Serb army, showed no emotion on the second day of his genocide trial as McCloskey showed judges a fleeting video of what he said were the bodies of executed Muslim men piled in front of a bullet-riddled wall.
On the first day of the trial Wednesday, the court's public gallery was crowded with victims' relatives who had angrily exchanged hand gestures with Mladic through the bulletproof glass separating them.
