Torts: Defences (Volenti (voluntary assumption of risk)/ Consent
…
Torts: Defences
-
-
Illegality/Ex turpi causa
(complete)
- criminal offences, reprehensible or grossly immoral conduct (United Project Consultants v Leong Kwok Onn [2005] SG)
- public conscience
- consistency and integrity in the law
- defeats elements in prima facie tort, e.g. DOC, SOC, causation, not strictly a "defence"
- traditionally based on public policy: against public conscience or encourage conduct contrary to the public good
- now, policy is also important but in a more pragmatic and nuanced form where there is less overt judgment
- “very difficult to state or rationalise, it being recognised as sitting more easily in the law of contract than of tort” (Reeves v Commissioner of Police of the Metropolis) -> reluctance assuaged with new policy view
Joint illegal enterprise
- P and D are participating in crime together
Australia and UK
SOC approach
SOC impossible to determine
(Jackson v Harrison, Mason J, Aus)Adopted by UKCA
- encouraged D to ride bike recklessly
(Pitts v Hunt)
Cessation of joint illegal activity + rejection of SOC approach
- start of car journey -> no DOC
- time she wanted to stop committing crime and get out of car (even though it was because D was driving erratically not because it was a crime) -> DOC start
- SOC can be easily determined -> standard of reasonably competent driver
HELD: no illegality
(Miller v Miller, Aus)
No DOC because impossibility of setting SOC
(Gala v Preston, Aus)
DOC approach
Adopted by Aus HC
- assumption that each participant in a joint illegal activity was equally responsible for the acts of the other
- P and D stole car, D crashed car
HELD: no DOC
(Smith v Jenkins, Aus HC)
Adopted by UKHC
(Ashton v Turner)
Causation approach
- TEST: whether P's own act was the cause of his own damage: unusual or increased risks of harm foreseeable from character of joint criminal enterprise, and risk materialises
- followed Gray v Thames analysis
- active encouragement as in Pitts v Hunt not required
(Joyce v O'Brien, UKCA, hanging off the back of a getaway vehicle)
Public policy approach: causation approach questioned
- causation approach not a blanket rule, may not be always appropriate, but public policy is always appropriate
(Hounga v Allen, UKSC, after Joyce)
Separate wrongs
(harder to succeed in defence, usually will fail)
- focus on P's connection or lack thereof with D's distinct wrong and proportionality
Exceptions
-
Public policy and serious/violent crimes
-
Clear public policy decision
- P mentally ill but not insane, did not turn up for appointments and prescriptions -> became paranoid, stabbed someone to death in unprovocaked attack (manslaughter (CHNATM))
- D local authorities did not have resources to chase him down
- P sued for deprivation of liberty
(Clunis v Camden)
Narrow and broad policy grounds
- train crash, PTSD, depression, D banged on his car window, PTSD triggered, P went home got knife and stabbed D, convicted for manslaughter
- public policy (narrow rule and broad rule): cannot claim for loss of liberty and earnings
- public policy is now broader, might vary from case to case (Lord Hoffman)
(Gray v Thames Trains)
-
Other non-tort cases
Crimes and non-crimes to which illegality applies
- S got injunction to stop A from infringing patent; but patent wasn't valid, A sued to recover money lost because of injunction
- patent in UK invalid; patent in Canada invalid
HELD: no illegality, act of infringing the Canadian patent, which was purely a matter of private law (not criminal), was not of sufficient ‘turpitude’ to raise an issue of public policy
-
- illegality would only apply when: (i) criminal or quasi-criminal ; (ii) dishonest or corrupt; (iii) clearly contrary to public policy, even when not actually criminal (eg prostitution); or breaches of statutes enacted to protect the public interest
(Les Laboratoires Servier v Apotex, Lord Sumption)
Flexible policy approach to crime
- conspiracy to commit insider dealing
- P have D money (620k pounds) to bet on bank's share price using inside information
- information did not materialise and D did not place bet
-
- flexible policy based approach: whether the public interest in preserving the integrity of the justice system ought to result in denial of the relief sought
- no public interest in letting D keep the money
-
- overturned Tinsey v Milligan [1994] cannot succeed on action which relies on his own wrong
(Patel v Mirza, UKSC)
-
Scope of defence in SG
Current law: Can apply to separate wrongs
- very thing principle applies: P handing in incorrect tax returns, D was employed to help P file taxes correctly
- not really a crime, only technically a wrong
-
- in cases which did not involve the ‘very thing’, illegality would succeed only where P’s conduct was truly reprehensible or grossly immoral
(United Project Consultants Pte Ltd v Leong Kwok, SGCA)
-
- specific v general
- burden on defendant
- on BOP
- multiple defences possible
- Courts are less willing to allow complete defences; partial defences are much more common and more commonly successful
