The European Court of Human Rights is due to rule on whether the Russian government should have done more to prevent a school siege in the city of Beslan in which more than 330 people died in 2004.
Chechen separatists took more than 1,000 hostages at School Number One, the vast majority of them children.
It ended when Russian security forces stormed the building. Survivors say the troops used excessive force.
No Russian official has been held responsible for the high number of deaths, which included 186 children.
Masked men and women, wearing bomb belts, burst into the school, opening fire in the courtyard as a ceremony marking the beginning of the school year was finishing.
The hostages were crammed into their school sports hall beneath explosives strung from the basketball hoops. Their captors were demanding Russian troops pull out of Chechnya.
The tense siege ended suddenly on the third day with two deadly explosions and intense gunfire. Witnesses described the operation by Russian security forces as chaotic, saying that the troops used excessive force and heavy weapons.
Only one of the hostage takers was caught alive and put on trial.
