A lawyer for freed Pussy Riot star Yekaterina Samutsevich is facing a reprimand for violating Russia's legal practice code during the case.

Violetta Volkova represented the feminist pop star during her court trial for hooliganism after she was arrested along with fellow bandmembers Maria Alekhina and Nadezhda Tolokonnikova last year (12).

The trio was found guilty and jailed for two years, but Samutsevich was freed from prison in October (12) after her sentence was commuted.

She had dispensed with Volkova's services before launching her appeal, and she later complained about the way the lawyer dealt with her case, alleging she supplied a substandard service, and officials at the Moscow Bar Association have now ruled Volkova did violate the industry's practice code.

The penalty to be imposed on Volkova will be announced next month (Jul13).

The three Pussy Riot members were arrested after performing a protest song against Russian President Vladimir Putin at a church in Moscow in February last year (12). Alekhina and Tolokonnikova are serving out their sentences at remote prison camps in the country.
