PROCEDURE IN TRIALS BEFORE THE HIGH COURT
(d) Arraignment
280.-(1) Any accused person upon whom an information is filed may plead–
(a) that he has been previously convicted or acquitted, as the case may be, of the same offence; or
(b) that he has obtained a pardon at law for his offence.
(2) If either of any plea referred to in subsection (1) is pleaded in any case and disputed by the prosecution to be true in fact, the court shall try whether such plea is true in fact or not.
(3) If the court holds that the facts alleged by the accused do not prove the plea, or finds that it is false in fact, the accused shall be required to plead to the information.
