Henderson v Dorset Healthcare University NHS Foundation Trust  EWHC 3032 (QB)
Ex turpi causa "On 25 August 2010 the claimant killed her mother. ... She pleaded not guilty of murder, but guilty of manslaughter by reason of diminished responsibility. Those pleas were accepted. ... The claimant remains in detention pursuant to the Mental Health Act. Long before the manslaughter, the claimant had been diagnosed as suffering from paranoid schizophrenia. At the time, she was under the care of the Southbourne Community Mental Health Team, within the defendant NHS Trust. An inquiry later made findings critical of the defendant's conduct. The core criticism was of a failure to act in a timely manner when alerted by a health worker, Ms Loyne, to a significant deterioration in the claimant's condition. In this unusual personal injury claim the claimant seeks damages against the defendant for personal injury in the form of psychiatric harm, and for the consequences of killing her mother. Proceedings were issued on 22 August 2013. The defendant admitted liability for negligence. Judgment on liability in negligence, with damages to be assessed, was entered by consent as long ago as 12 May 2014. By an order of 17 February 2016 Master Cook directed the trial of preliminary issues which had been proposed by the defendant. That trial is listed to take place over 3 days in the week commencing 5 December 2016. The preliminary issues concern the extent to which the claimant's claims for damages are barred by the rule of law which prohibits a person from recovering damages for the consequences of their own illegality. ... It was on Monday 14 November 2016, seven working days before the start of the preliminary issue trial window, that the claimant's solicitors filed her application. It seeks permission to amend by adding (1) claims under the Human Rights Act 1998, alleging infringement of the claimant's rights under Articles 3 and 8 of the Convention, and (2) a claim for an extension of time for bringing those claims, pursuant to s 7(5)(b) of the HRA."
