MOSCOW, December 7 - RAPSI. Renowned whistleblower and lawyer Alexei Navalny appealed a court order to sentence him to 15 days in jail for his involvement in an unauthorized procession in central Moscow and disobeying the police on Monday night, the court told the Russian Legal Information Agency (RAPSI/rapsinews.com).

"Navalny's appeal, in which he requests to recognize the sentence by the magistrate's court as unsound and illegal, will be heard today at 14.30 Moscow time," Yekaterina Ilyina, the Moscow District Court's spokeswoman, said.

The magistrate's court convicted Navalny on Tuesday for disobeying police and sentenced him to an administrative arrest.

The police detained over 300 people in central Moscow for unauthorized demonstrations on Monday night following the parliamentary elections where United Russia, the ruling party, is the frontrunner.
