Criminal law – Murder. Whether or not the spirit of Code C of the Police and Criminal Evidence Act 1984 was engaged by the fact of a prison officer's occupation, the circumstances in which the observations of the defendant's admission of murder had been made did not engage the Code or the need to obtain a signed copy of the comment. The Court of Appeal, Criminal Division, in dismissing the defendant's appeal against conviction for murder, further held that the presence of a knife did not constitute an overwhelming supervening event.
