MOSCOW, November 12 - RAPSI. On December 5 the Moscow Commercial Court will hear Gazprom's claim to invalidate the Federal Antimonopoly Service's (FAS) repeated prohibition of the bank's acquisition of 50.9 percent of the shares in Moscow United Electric Grid Company (MOESK), a court spokesperson told RAPSI.

The hearing date was set in aftermath of the preliminary hearings. The court joined as a third party the Moscow United Electric Grid Company (MOESK), which lays no claims to the subject of the dispute.

Gazprombank disputed the Federal Antimonopoly Service's (FAS) July 6 decision to reject its acquisition of 50.9 percent of the voting shares in Moscow United Electric Grid Company (MOESK) for the purposes of trust management.

The decision to bar the acquisition once again was influenced by several facts, including the bank's affiliation with Gazprom, according to the regulator's statement.

The federal service holds that this transaction would combine the power distribution business with the power generation business under a single entity - Gazprom - in contravention of the law.

Furthermore, the bank has failed to disclose the requisite information in full, according to the federal service.

MOESK is Russia's largest electric grid company, serving Moscow and the Moscow Region.
