Jailed Pussy Riot star Nadezhda Tolokonnikova's parole application has been referred to a Russian Supreme Court. The musician, who was sentenced to two years in prison for hooliganism last year (12), was denied early release in April (13) but officials at Zubovo-Polyansky Court of the Republic of Mordovia have now ordered a review. Documents on Tolokonnikova's case have been sent to judges at the republic's Supreme Court to consider if the original decision to deny parole was unduly harsh. Tolokonnikova and her bandmates Yekaterina Samutsevich and Maria Alekhina were jailed for performing a protest song against Russian President Vladimir Putin at a church in Moscow in February last year (12). Samutsevich was freed in October (12) when her sentence was commuted, but her two pals remain behind bars.
