Facts

Miss Instan lived with her 73 year old aunt, who was in good health until she developed gangrene in her leg and became unable to look after herself. Miss Instan lived in the house, was supported by her aunt's money, and was the only person who knew of her condition. For the last 12 days of the aunt's life, Miss Instan gave her no food and did not call a doctor, and the aunt died. Miss Instan was convicted of manslaughter.

Legal principle

The court upheld the conviction. Lord Coleridge CJ said that the prisoner was under a moral obligation to her aunt, and that a legal common law duty arose from her having taken upon herself the care of her aunt, who was dependent on her and could not obtain help from anyone else. Her failure to perform that duty, which accelerated the aunt's death, was a sufficient basis for liability for manslaughter.
