Alexander Lewis-Ranwell v G4S Health Services (UK) Ltd & Ors

Alexander Lewis-Ranwell v G4S Health Services (UK) Ltd & Ors

The illegality defence does not bar a negligence claim where the claimant committed homicide but was found not guilty by reason of insanity, as the necessary element of knowledge of wrongdoing or moral culpability is absent. Public policy does not require denial of the claim in these circumstances.

Legal Issues

  1. 1 Does the illegality defence (ex turpi causa) bar a negligence claim where the claimant committed homicide but was found not guilty by reason of insanity?
  2. 2 Is knowledge of wrongdoing or moral culpability required for the illegality defence to apply in tort?
  3. 3 Should public policy preclude recovery for losses resulting from an unlawful act committed while insane?

Ratio Decidendi

The illegality defence does not bar a negligence claim where the claimant committed homicide but was found not guilty by reason of insanity, as the necessary element of knowledge of wrongdoing or moral culpability is absent. Public policy does not require denial of the claim in these circumstances.

Court Disposition

Appeal dismissed (by majority); strike-out refused; claim proceeds.

Orders

  • The appeal is dismissed.
  • The action will proceed against the Appellants as regards the claim in negligence and under the Human Rights Act, subject to any further appeal.
