Ashford v Thornton (1818) 106 ER 149 is an English law case in the Court of King's Bench that upheld the right of the defendant, on a private appeal from an acquittal for murder, to trial by battle. In 1817, Abraham Thornton was charged with the murder of Mary Ashford. Thornton had met Ashford at a dance, and had walked with her from the event. The next morning, Ashford was found drowned in a pit, with little outward signs of violence. Although public opinion was heavily against Thornton, the jury quickly acquitted him, and also found him not guilty of rape.
