(1) If any person, upon arraignment before the High Court in its criminal jurisdiction or during his or her trial for any offence, is found by the jury to be insane, the Court shall order that the trial of such person be postponed until he or she becomes of sound mind and that in the meantime he or she be detained in custody in such mental hospital as the Court appoints until Her Majesty's pleasure is known, and thereupon the Governor General on behalf of Her Majesty may give such order for the safe custody of such person until he or she becomes of sound mind as the Governor General thinks fit.
(2) If any person charged before any Court with any crime or offence appears to the Court to be of unsound mind and it shall not be practicable to hold an inquiry as to the state of mind of such person, it is lawful for the Court to order such person to be detained in custody in a mental hospital, which for this purpose shall be deemed to be a prison, until an inquiry can with reasonable expedition be held.
