In the latest setback for the James “Whitey” Bulger’s defence case, newly appointed U.S. District Court Judge Denise Casper ruled Thursday that the mobster cannot claim immunity for his crimes as a defense in his trial.

“In response to Bulger’s motion for discovery relating to this issue, the government denied the existence of any such immunity agreement, but also argued that even if such an agreement existed, it could not encompass crimes committed after the alleged agreement’s execution,” Casper wrote in her ruling on Thursday. “The Court has determined that the issue of immunity is not an issue for the jury.”

“The Court concludes, on the present record, that there has been an insufficient proffer that any such promise of immunity was made by a person with actual authority to make it or that Bulger detrimentally relied upon such promise, or that any such agreement was enforceable as a matter of law,” she wrote in her ruling.

Bulger claims that the now deceased federal prosecutor Jeremiah O’Sullivan verbally promised that he would not be prosecuted for the the crimes he committed.

James ‘Whitey’ Bulger, 83, is to face charges of Federal racketeering and is accused of participating in 19 killings during the 1970s.

He fled Boston in 1995, shortly after his indictment and was on the run for 16 years before he was captured in June 2011 in Santa Monica, California.

Earlier this month Federal officials warned that space would be limited in the high profile trial of the Boston crime boss, but they said seats will be reserved for Bulger’s family and the families of his 19 alleged victims.
