Article 59 Presence of witnesses

Except for the accused and any expert or character witness, a witness as to fact shall not, except by leave of the court, be in court while not under examination.

If while a witness is under examination a question arises as to the admissibility of a question or otherwise with regard to the evidence, the court may direct the witness to withdraw for the duration of the discussion.

The court may direct any expert or character witness present in court to withdraw if the court considers in the interests of justice that his presence is undesirable.
