Fang v R

Fang was convicted of a serious crime and appealed against his conviction. The primary issue before the court was whether the trial judge had erred in declining to leave the defence of mental illness to the jury. The court was also required to determine whether this error resulted in a substantial miscarriage of justice. The court examined the evidence presented and the trial judge's directions to the jury regarding the defence of mental illness. It was noted that the trial judge had declined to leave the defence to the jury, instead directing them to find the defendant not guilty by reason of mental illness if they were satisfied that the defendant was suffering from a mental illness at the time of the offence.

The court found that the trial judge's decision not to leave the defence of mental illness to the jury was an error, as the defence should have been left to the jury to determine. However, the court also found that this error did not result in a substantial miscarriage of justice, as the evidence overwhelmingly supported the defendant's guilt and the jury would likely have found him not guilty by reason of mental illness regardless. The court held that the error did not affect the safety of the verdict and that the appeal should be dismissed. The court further found that there were no other grounds for allowing the appeal and that the conviction should be upheld.
