Former death-row inmate Mumia Abu-Jamal, convicted for the 1981 murder of Philadelphia police officer Daniel Faulkner, has asked a Philadelphia judge to give him the chance to appeal yet again.

In the latest chapter of the 37-year saga that is the Abu-Jamal case, defense attorneys on Monday argued that former Philadelphia District Attorney Ronald D. Castille, who oversaw prosecutors’ response to Abu-Jamal’s appeal in the early 1990s, should not have weighed in on those same issues as a justice of the state Supreme Court years later.
