BOSTON (WHDH) -- A judge delayed the trial for James "Whitey" Bulger by about four months Monday after his lawyer said a member of the federal government in the 1970s had promised Bulger immunity from crimes he committed or would commit.

J.W. Carney Jr., Bulger’s lawyer, said he needed more time to prepare and had argued the trial should be delayed from this November to November 2013. A federal magistrate judge on Monday set the new date for Monday, March 4, 2013.

“We shall be filing a motion to dismiss based on the fact that a member of the federal government promised James Bulger regarding any crimes that he had committed or any crimes that he would commit in the future,” said J.W. Carney, Bulger’s attorney.

In the filing, Bulger’s attorneys say he reached an agreement with the Department of Justice in the 1970’s. That immunity agreement they allege fully protects Bulger from prosecution of all crimes he committed. The filing also asks that Judge Richard Stearns step aside because he used to work for the federal government.

“I think if the government gave Bulger immunity -- I just can’t believe that the government would be that stupid to do that. And if they did, if he’s got immunity, then step up to the plate and admit that he did everything and take your medicine,” said Steven Rakes, alleged Bulger victim’s family member.  

“A license to kill according to Mr. Carney. And it gets you boiling. I just -- I don’t even know how to even put the thoughts together what I’m thinking,” said Steven Davis, alleged Bulger victim’s brother.

Carney says he needs time to review evidence; 300,000 pages of documents turned over by prosecutors.

Bulger's defense team will not say when they are going to file the motions to dismiss all of the charges. They say when they do, they will reveal the name of the federal employee who allegedly gave the immunity deal to Whitey Bulger.
