Defences Flashcards
what are the 3 main defences in negligence?
- illegality (ex turpi causa)
- contributory negligence
- consent (voluntary acceptance of consequence)
what is the ex turpi causa maxim?
the illegal or wrongful nature of C’s conduct may bar their claim in tort
what is the root of the illegality defence? (incl. case)
public policy - ‘no court will lend its aid to a man who founds his cause of action upon an immoral or illegal act (Holman v Johnson, Lord Mansfield)
what is required to run the illegality defence? (incl. case)
National Coal Board v England - D must establish a causal connection between (i) C’s wrongful conduct and (ii) the harm suffered by C
illegality and judicial discretion? (incl. case)
Pitts v Hunt (Dillon LJ) - even though C was engaged in illegal activity which brought about their injury, it does not automatically bring it about that his claim for damages because of D’s negligence must be dismissed
what is the UK conception of the illegality defence? (incl. case)
based on considerations of public policy e.g. compensating C would be ‘shocking to the public conscience’ or send out an undesirable signal to criminals and other wrongdoers (Kirkham v Chief Constable of Greater Manchester Police)
what is the Australian conception of illegality?
C’s participation in criminality or wrongdoing makes it impossible for judges to specify a standard of care (Jackson v Harrison)
HL criticism of the scope of illegality? (incl. case)
- Tinsley v Milligan - HL disapproved the ‘public conscience’/’shock’ test
- Lord Goff: the ‘shock’ test amounts to saying that judges have a discretion to refuse relief
joint illegal activity? (incl. case)
- Pitts v Hunt - no duty of care will be recognised between participants to a joint criminal enterprise if the enterprise is such that it would be impossible or not feasible to ask how much care the reasonable person in D’s position would have taken in the circumstances.
- Beldam LJ: to compensate C would be at odds with Parliament’s intentions in enacting road traffic legislation (policy-based reasoning)
can C sue their own victim? (incl. case)
- Revill v Newsbury - yes
- C tried to break into D’s shed; D used a shotgun to defend himself
- damages awarded to C; sum awarded reduced by 2/3
academic commentary: response to Revill (incl. quote)
- Weir - the authority of the Pitts decision was ‘dismissed’ - it caused an imbalance as C can sue their victim (Revill), but not their accomplice (Pitts)
- ‘Many more decisions like this and the Court of Appeal will forfeit the respect of lawyer and lay[person] alike’
example of a case in which illegality was relied upon successfully
- Clunis v Camden and Islington Health Authority - C was found guilty of manslaughter and sued D in negligence for lack of psychiatric support after being discharged from hospital.
- illegal act (manslaughter) was found and C knew or could be presumed to know that his conduct was wrongful
- policy aspect - deterring criminal acts
principle of consistency? (incl. case)
- Gray v Thames Trains Ltd - illegality defence applied; the civil law must be applied in ways that are consistent with any criminal sentence already imposed
- Canadian case law has identified consistency as the sole justification for the illegality defence (Hall v Hebert)
other than consistency, what are the different justifications for the illegality defence? (incl. case and 2 academics)
- deterrence (Clunis v Camden and Islington Health Authority)
- retribution (‘just deserts’)
- maintaining the integrity of the legal system (Weir)
- outlawry - C is effectively put beyond the law’s protection (Hervey)
the HL on justifications for the illegality defence? (incl. case)
different reasons could be invoked in different circumstances (Lord Hoffmann, Gray v Thames Trains Ltd)
