MOSCOW, April 4 - RAPSI. The Moscow City Court postponed until May 22 the hearing of renowned whistleblower Alexei Navalny's application disputing the court's refusal to obligate the Federal Antimonopoly Service's St. Petersburg Department to accept his appeal against a power supply system tender, the court told the Russian Legal Information Agency (RAPSI/rapsinews.com) on Friday.

"Navalny seeks to reverse the Lyublinsky District Court's judgment and to order the watchdog to accept his complaint," the court said.

The plaintiff said in his statement of claim that the government's website published in August 2011 documents and advertisements on a public tender for organizing and commissioning power supply systems. Navalny said a number of tender document provisions violated the law and attempted to challenge the tender with the Federal Antimonopoly Service, the court said.

The watchdog added that it dismissed Navalny's petition as he filed his complaint as a Sberbank shareholder, although it was not among the tenderers.

The court ruled that the watchdog's decision is valid and dismissed Navalny's petition. The judgment has not yet to come into force as the blogger appealed the ruling.
