Article 147

At any time before making a decision of guilty or not guilty the Court may call any witness whose testimony it considers necessary in the interests of justice.

The prosecutor may call any witness whose name does not appear on the list of prosecution witnesses if the Court is satisfied that he is a material witness who could not have previously been identified as such by the prosecutor and the application for a summons is not being made for the purpose of delaying the case.

The accused may call any witness if the Court is satisfied that he is a material witness and the application for a summons is not being made for the purpose of delaying the case.
