An unusual legal battle in the trials of the officers charged in the death of Freddie Gray could propel the case all the way to the Supreme Court.

Circuit Judge Barry G. Williams ruled that Baltimore Officer William G. Porter could be compelled to testify against his fellow cops, even though he has pleaded the Fifth and has pending charges for which he will be tried. Williams’s decision was called highly unusual by many legal experts, and Maryland’s highest court ruled Thursday to postpone the officers’ trials until the Maryland Court of Appeals decides whether Porter can be forced to testify.

High-profile defense attorney Barry Slotnick told The Daily Caller News Foundation the case’s Fifth Amendment questions makes it “begging to go to the Supreme Court.”

“One of the things that we have to understand is that prosecutors cannot call people to the witness stand and have them incriminate themselves unless they give people immunity,” Slotnick told TheDCNF. “The Constitution is very clear.”

Police arrested Gray in April and transported him in the back of a police van. Gray appeared healthy when arrested but was injured within an hour after his encounter with police. His spinal cord was severely damaged and he died a week later from the injuries.
