The Massachusetts Supreme Judicial Court recently considered a defendant’s challenge that his second degree murder conviction should be overturned because his constitutional rights were violated when the trial judge refused to grant immunity to potential defense witnesses. In the case of Commonwealth v. Brewer, although the SJC affirmed the defendant’s conviction, the court left open the issue of defendant’s, as opposed to only the government, having a means to offer immunity to potential witnesses.
In this case, the victim had been shot after leaving a party, though the evidence suggested that he was not the intended target of the shooting. The government called three witnesses who claimed the defendant was the shooter, one of whom was granted immunity in exchange for his testimony. The defense, however, attacked these witnesses’ credibility and asserted that one of these three witnesses was actually the shooter.
