Ulman and three co-defendants were acquitted twice on charges of murder and abuse of office by the North Caucasus District Military Court, but the Russian Supreme Court's military court overturned the rulings.
The Supreme Court upheld an appeal filed by prosecutors in the case and backed by lawyers acting for the victims, and ruled June 7 that a professional non-jury court should hear the case.
In January 2002, a reconnaissance group attacked a jeep in Chechnya, killing six locals and burning a car.
The Constitutional Court ruled April 6 that serious crimes committed in war-torn Chechnya could be tried without a jury.
The ruling came following a request from Chechen President Alu Alkhanov over the legality of several articles in laws on military courts that he said gave the military rights not enjoyed by ordinary citizens.
Alkhanov said previously that servicemen suspected of crimes in Chechnya were tried in jury courts, while ordinary Chechen defendants would only be able to have jury trials as of 2007. He also said the jury in the Ulman case had not included ethnic Chechens, which had influenced the court decision.
