Any proceedings against an accused shall be held in open court, but the presiding judge or justice may, on application of the prosecutor or a witness or on his or her own motion, order the exclusion of all or any members of the public from the court room for all or part of the proceedings, or order that the witness testify behind a screen or other device that would allow the witness not to be seen by members of the public, if the judge or justice is of the opinion that such an order is in the interest of public morals, the maintenance of order or the proper administration of justice or is necessary to prevent injury to international relations or national defence or national security.
