Attorneys for Officer William Porter and five other officers charged in connection with the death of Freddie Gray argued in the Maryland Court Appeals against prosecution motions compelling him to tesify in upcoming trials.
Porter was the first of six officers to be tried in the death of Gray last April. His trial ended in a hung jury, but prosecutors say he will be retried in June.
However, Judge Barry Williams ordered Porter to testify in the trial of Caesar R. Goodson Jr. that was originally scheduled for Feb. 22. Porters lawyers appealed that order, arguing that forcing him to testify would violate Porter's Fifth Amendment rights against self incrimnation.
