PART IV - PROVISIONS RELATING TO CRIMINAL PROCEEDINGS
94 Person convicted or acquitted not to be tried again for same offence
A person who has been once tried by a Court of competent jurisdiction for an offence and convicted or acquitted of that offence shall, while such conviction or acquittal has not been reversed or set aside, not be liable to be tried again on the same facts for the same offence or any offence in respect of which he could have been convicted on the charge, or any count of the charge, of which he was acquitted and, if required by any Court to plead to an information or charge in respect of such an offence, may, instead of pleading to the information or charge, plead that he has already been convicted or acquitted of that offence, and the Court shall thereupon try whether that plea is true and only if it finds the plea to be untrue shall the Court require him to plead to the information or charge or to the count relating to that offence.
