ANNAPOLIS (AP) - Maryland's second-highest court has scheduled a March hearing on a dispute that has stalled the murder trial of a Baltimore police officer in the death of Freddie Gray.

The Court of Special Appeals said Tuesday that it will hear oral arguments March 4 on whether Officer William Porter must testify against Officer Caesar Goodson.

Goodson drove the van in which Gray suffered a fatal neck injury. Porter testified at his own trial that he told Goodson that Gray had asked for medical help. Porter's trial ended in a hung jury. He's awaiting retrial.

The trial judge has ordered Porter to testify against Goodson despite Porter's assertion that he has a right not to incriminate himself.

On Monday, Goodson's trial was suspended until the matter is resolved.
