Two jailed members of punk protest group Pussy Riot are taking their fight for freedom to Russia's highest court. Nadezhda Tolokonnikova and Maria Alekhina lodged documents with officials at the Supreme Court of the Russian Federation on Wednesday (20Nov13) in a bid to have their two-year prison sentences overturned. The two women argue they were unfairly punished for performing a protest song against President Vladimir Putin in a Moscow church last year (12). Various legal appeals against their punishment have failed, so now both women have applied to judges at Russia's highest court. The move is supported by the country's Human Rights Commissioner Vladimir Lukin. Tolokonnikova and Alekhina are both due for release in March (14). A third Pussy Riot member, Yekaterina Samutsevich, was freed in October (12) when her sentence was commuted.
