According to reports, Carter mentioned that he was feeling unwell and asked a policeman for help from the courtroom with his books.
He was at the time in High Court No. 5 before Justice Jacqueline Cornelius, who was hearing bail applications.
It was while being assisted from the courtroom that Carter allegedly began stumbling, his speech became slurred and he began experiencing difficulty in moving the limbs on the left side of his body.
It is understood that Andrew Pilgrim QC called for an ambulance while Principal Crown Counsel Elwood Watts immediately prayed for Carter.
The ambulance was summoned to the Supreme Court and the defence attorney left, accompanied by his work colleague Angella Mitchell-Gittens.
Carter is one of the attorneys attached to Pilgrim & Associates.
