In a ruling his defense team is calling a major victory, Mumia Abu-Jamal has won the right to appeal his murder conviction on three separate grounds. Convicted in 1982 for the murder of a police officer, Mumia will be able to appeal on grounds of both judge and jury bias. He’ll also appeal on the basis the trial prosecutor misled jurors. In a news release, Mumia’s attorney Robert Bryan wrote the court’s rulings are: “of enormous constitutional significance and go to the very essence of Mumia’s right to a fair trial… Today we achieved a great victory in the campaign to win a new trial and the eventual freedom of Mumia.” Opening briefs in the appeal will be heard on January 17th.
