R v Blaue [1975] 3 All ER 446
D stabbed V, a Jehovas witness. Although the wound was life-threatening, a minor opperation and blood transfussion would have saved her. V declined the transfussion under the grounds of her faith and signed a notice to the effect that she was aware this would cause her death. Death occured less than twenty four hours later. Neither party argued she was mentally unfit to make this decision. D appealed his conviction to the court of appeal
Held- a refusual of medical treatment does not in itself constitute a break in causation. D must take his victim "as he finds him".
