Criminal law – Murder. The Court of Appeal, Criminal Division, in dismissing the defendant's appeal against conviction for murder, held that while any jury in a case where diminished responsibility was raised would need in the light of the available psychiatric evidence to assess a defendant's thinking processes in the context of assessing his ability to form a rational judgment, it was likely to be over-refined to divorce that consideration relating to a defendant's thinking processes from the actual 'outcome' in the case. In the present case, the jury had not been materially misdirected in any sense and had been fully entitled to conclude as it had.
