A federal judge in Boston has ruled that notorious gangster James “Whitey” Bulger’s entire FBI informant file can be presented at his trial, which begins this week.

US District Judge Denise J. Casper made the ruling in a hearing this afternoon as she considered a variety of last-minute motions in the case.

Bulger has denied being an FBI informant. But his informant file is extensive, the Globe has reported.

Bulger attended the hearing at US District Court on the city’s waterfront, wearing an orange jail jumpsuit. He brought two pairs of glasses, using one pair to look at documents and a separate pair to look at the judge on the bench.

The lawyers for both sides engaged in heated arguments.

Casper also ruled that while relatives of Bulger’s alleged murder victims can testify during the trial, they will not be allowed to talk about the effect the slayings had on them.

Bulger, 83, faces a 32-count indictment that accuses him, while he ran a criminal enterprise from 1972 to 2000, of committing 19 murders, extortion, money laundering, corrupting law enforcement officials, and firearms violations. Bulger has pleaded not guilty to all charges and his attorneys say he will testify in his own defense.

Jury selection is expected to begin Tuesday.
