The Courts of Justice Act, 1924

Appellant guilty but insane.

35.—If on any appeal pursuant to certificate or leave granted, as aforesaid, it appears to the Court of Criminal Appeal that although the appellant was guilty of the act or omission charged against him, he was insane at the time the act was done or omission made, so as not to be responsible according to law for his actions, the court may quash the sentence passed at the trial and order the appellant to be kept in custody as a criminal lunatic, in the same manner as if the verdict had been found by the jury to that effect.
