If, after the hearing, the evidence of a witness appears to be false, the president, either of his own motion or at the request of the public prosecutor or one of the parties, shall cause the precise statements of the witness to be recorded in the notes for the hearing.
He may specially enjoin this witness to remain at the disposal of the court, which will hear him again, if necessary.
If the judgment is to be given on the same day, the president may also have this witness guarded by the police in or outside the courtroom.
After the judgment on the merits has been read, the court orders the witness to be taken before the public prosecutor, who requires an investigation to be opened for perjury.
A record of the facts or statements from which the perjury may result shall be drawn up by the court forthwith, after the judgment on the merits has been read.
This record and a copy of the notes of the hearing shall be forwarded without delay to the public prosecutor.
