Procedure on repeated committal of a prison offence

If any person in the prison premises is guilty of an offence against prison discipline, which by reason of his having frequently committed such offence or otherwise, in the opinion of the officer-in-charge, is not adequately punishable by the infliction of any punishment which he has the power to inflict under this Act, the officer-in-charge may forward the case of such prisoner to the competent Magistrate having jurisdiction, together with a statement of the circumstances, and such Magistrate shall thereupon try the charge so brought against the prisoner, and, upon conviction, may sentence him to imprisonment which may extend for a period up to three years. Such term shall be in addition to any other term which such prisoner may be already undergoing.
