Henderson v Wilcox  EWHC 3469 (Ch),  MHLO 108
"The claimant in this case is Ian Henderson. Ian's mother, Mrs Lillian Henderson, died on 2 April 2013 as a result of injuries sustained in a severe assault on her by Ian on the night of 13 March 2013. Ian was convicted of manslaughter at a trial on 15 September 2014, his plea of guilty to that charge and not guilty to murder having been accepted on the basis that he had not intended to kill his mother or cause her really serious injury. He was sentenced (with the agreement of the prosecution) to be detained in hospital under section 37 Mental Health Act 1983, the judge being satisfied that he suffered from a mental disorder such as to make his detention and treatment in hospital appropriate (section 37 (2)), coupled with a restriction order made under section 47 of that Act in order to prevent the public from serious harm if he should be at large. ... Mrs Henderson's will made in 2006 left her entire estate to Ian if he survived her, but it is accepted that by virtue of his having caused her death by his own criminal act prima facie Ian is excluded from benefitting under the will under the common law rule known as the 'forfeiture rule'. The court however has power to modify the application of that rule in certain circumstances pursuant to the Forfeiture Act 1982, and Ian brings this claim seeking, principally, an order under that Act that permits him to inherit his mother's estate."
