MOSCOW, July 11. /TASS/. A Moscow court has refused to accept a lawsuit from Russia’s Federal Penitentiary Service (FSIN) to overturn opposition figure Alexey Navalny’s suspended sentence to real jail time under the Yves Rocher embezzlement case, court spokesman Viktor Vasilyev told TASS on Tuesday.

"The court has returned the lawsuit as it was not signed by the proper person," he said.

The court earlier received a request from the deputy head of the FSIN penal inspection for Moscow to overturn Navalny’s suspended sentence to real jail.

The FSIN numerously requested the court earlier to replace Navalny’s suspended sentence with a real prison term but none of the attempts crowned with success.

On December 30, 2014, Moscow’s Zamoskvoretsky Court found the Navalny brothers guilty of embezzling Yves Rocher funds and handed Alexey Navalny a suspended sentence of 3 years and 6 months tacking it along with a probation period of five years. His brother Oleg Navalny was sentenced to 3 years and 6 months behind bars.
