Criminal law – Manslaughter. The judge's direction to the jury on attribution of knowledge of the business (or a worker) with that of the defendant on the basis that the defendant had been responsible for the system in the restaurant had rendered his conviction unsafe. However, the Court of Appeal, Criminal Division, in allowing the defendant's appeal against conviction for manslaughter on that ground, held that the judge had not been wrong to refuse to direct the jury to consider whether there had been a serious and obvious risk that the defendant's breach of duty would cause the deceased to die, as opposed to others suffering from peanut allergy.
