R v Willoughby

 A man burned down his pub so as to avoid paying the mortgage and a person dies. He was convicted of manslaughter after the judge directed that on account of his ownership the jury may infer that he had a duty of care. He appealed that this was a misdirection. The CA conceded this, but said that where there was evidence suggesting a duty of care, it was for the jury to decide if it existed. The fact that he stood to gain (financially) from burning the pub down meant he had a duty not to kill in the process.
