BOSTON, May 2 (Reuters) - A federal judge has rejected accused mobster James "Whitey" Bulger's plan to argue before a jury that he could not be prosecuted for the 19 murders he is accused of due to an immunity agreement worked out with a now-deceased prosecutor.
In a court filing made public on Thursday, U.S. District Court Judge Denise Casper said lawyers for Bulger could not make the case at trial that he could not be prosecuted.
Casper was appointed to hear the Bulger case in March, after the court of appeals removed Judge Richard Stearns from the case due to his history as a federal prosecutor.
The trial is due to begin in June. (Reporting by Scott Malone; Editing by Gerald E. McCormick)
