A federal court is set to hear an appeal by Boston gangster James "Whitey" Bulger, who was convicted nearly two years ago in 11 killings and other underworld crimes during the 1970s and '80s.

The 1st U.S. Circuit Court of Appeals on Monday scheduled oral arguments in Bulger's appeal for July 27.

The 85-year-old Bulger is serving life in prison after being convicted in a sweeping racketeering indictment in August 2013.

Bulger was one of the nation's most-wanted fugitives after he fled Boston ahead of a 1994 indictment. He was captured in Santa Monica, California, in 2011.

In his appeal, he argues that he was not given a chance to fully present his claim that a now-deceased federal prosecutor had given him immunity.
