"Today we received the copy of the court judgment, we will study it and appeal the verdict. We definitely won't be able to complete it this week because of the large volume of the document and the number of violations it contains. We will analyze it in detail and make [an appeal]," Nikolai Polozov told RAPSI, the Russian Legal INformation Agency.
The three members of the all-woman band were convicted Friday of holding an anti-Kremlin "punk prayer" in a Moscow cathedral in February.
They have already spent five months in detention, which Russian law says is equal to 10 months in prison.
Earlier in the day, the Web site for the Russian court where members of the band were convicted was attacked by computer hackers.
A message calling for the release of the band members was posted on the site for the Khamovnichesky Court, RIA Novosti reported.
The hackers posted the band's new single, "Putin Ignites the Fires of Revolution," that has been posted on YouTube, as well as a music clip with homosexual content by a Bulgarian pop-folk singer.
Some of the sections on the site were also renamed with expletive-laden epitaphs.
