The Communists, who won 57 seats in the 450-seat Russian parliament, requested that the court overrule the election results, announced by the Central Election Committee, saying that they had been falsified by the ruling United Russia party.

"According to my information, a preliminary session of the Supreme Court has been called for June 10 [to look into the claims]," said Nikolai Konkin.

The lawsuit, which was filed in late May, also alleges "media discrimination against the Russian Communist Party and other participants in the election on behalf of United Russia," said the head of the party's legal department, Vadim Solovyov.

Solovyov added that the case material backing up the Communist Party's claims was so extensive, the documents weighing over 30 kg (66 lbs), that a vehicle was required to deliver them to court.
