R v Riddell

The appeal before the court was brought by a defendant who had been found guilty of an offence by a jury but was later determined to be not guilty by reason of mental illness, pursuant to section 5 of the Criminal Appeal Act 1912. The defendant sought to challenge the decision of the trial judge, arguing that the special verdict of not guilty by reason of mental illness should not have been returned and that the court should have allowed an appeal. The central legal issues before the court were whether the defendant had properly raised the defence of mental illness and, if so, whether the defendant was entitled to appeal the verdict.

The court found that the defendant had indeed raised the issue of mental illness in the trial court, thereby satisfying the requirements for the special verdict. The court also considered the effect of section 7(4) of the Criminal Appeal Act 1912, which stipulates that if the appeal court finds the appellant to be mentally ill, the appellant must be detained in a psychiatric institution. The court concluded that the appeal was validly taken and that the appeal process should proceed to determine whether the defendant was indeed mentally ill at the time of the offence.

The court held that the appeal was properly before it and that the defendant was entitled to have the matter determined by the appeal court. The court found that the trial judge had correctly applied the law in returning the special verdict and that the appeal did not provide grounds for altering the verdict. The court further found that, if the appeal were to succeed, the consequences outlined in section 7(4) of the Criminal Appeal Act 1912 would apply.

The final orders of the court were that the appeal was dismissed, and the defendant was to remain subject to the special verdict of not guilty by reason of mental illness. If the defendant were found to be mentally ill on appeal, the defendant would be detained in a psychiatric institution in accordance with the provisions of section 7(4) of the Criminal Appeal Act 1912.
