Defences (Copy)

Introduction to Defences in Tort

• Purpose:
  • Defences allow a defendant to avoid or reduce liability in a tort claim.
  • They ensure fairness by balancing claimant protection with the defendant’s ability to argue mitigating factors.
• Types:
  • Full defences eliminate liability completely.
  • Partial defences reduce the amount of damages payable.

Consent (Volenti Non Fit Injuria)

1. Definition:
   • Translates to “to one who volunteers, no harm is done.”
   • If proven, this full defence removes the defendant’s liability.
2. Key Elements:
   • Voluntary Agreement:
     • The claimant must have freely agreed to accept the risk.
     • Example: Risks inherent in sporting activities.
   • Full Knowledge:
     • Claimant must be fully aware of the nature and extent of the risk.
     • Case Example:
       • Nettleship v Weston (1971):
         • Consent was invalidated as the instructor did not waive claims for negligence.
3. Application in Contexts:
   • Medical Treatment:
     • Valid consent must be informed and specific to the treatment provided.
     • Case Example:
       • Chatterton v Gerson (1981): General consent suffices if risks are broadly explained.
   • Sports:
     • Participants consent to risks within the rules of the game.
     • Case Example:
       • Condon v Basi (1985): Reckless acts beyond the rules void consent.
4. Limitations:
   • The Unfair Contract Terms Act 1977 prevents exclusion of liability for death or personal injury in business settings.

Contributory Negligence

1. Definition:
   • A partial defence reducing damages proportionate to the claimant’s responsibility for their harm.
2. Legal Framework:
   • Established by the Law Reform (Contributory Negligence) Act 1945.
   • Damages are reduced based on what is “just and equitable.”
3. Application:
   • Applies across multiple torts, including negligence and occupiers’ liability.
   • Does not apply to intentional torts like assault.
4. Case Examples:
   • Sayers v Harlow UDC (1958):
     • Damages reduced for a claimant attempting to escape a stuck lavatory.
   • Jackson v Murray (2015):
     • A child’s damages reduced due to contributory negligence in a traffic accident.

Inevitable Accident

1. Definition:
   • A defence claiming that harm occurred despite the defendant’s reasonable care.
   • No liability arises if the event was unavoidable.
2. Example:
   • Harm caused by unforeseeable mechanical failure despite proper maintenance.

Act of God

1. Definition:
   • Natural events, unforeseeable and unpreventable, may exempt liability.
   • Examples include extreme weather conditions.
2. Limitations:
   • Rarely succeeds unless the event was truly extraordinary.
   • Case Examples:
     • Nichols v Marsland (1876):
       • Flooding caused by unprecedented storms excused liability.

Necessity

1. Definition:
   • Used to justify actions taken to prevent greater harm.
   • Commonly applies in cases of trespass or battery.
2. Medical Applications:
   • Doctors may perform life-saving procedures without consent in emergencies.
   • Case Example:
     • F v West Berkshire Health Authority (1989):
       • Sterilization of a mentally incapacitated woman was justified under necessity.
3. Limitations:
   • Courts are reluctant to allow necessity when harm to property or individuals occurs without extreme justification.

Statutory Authority

1. Definition:
   • Provides full defence if the defendant’s actions were authorized by legislation.
   • Common in nuisance claims.
2. Case Examples:
   • Green v Chelsea Waterworks Co. (1894):
     • No liability for water main bursts as maintenance was statutorily required.

Illegality

1. Definition:
   • A claim cannot arise from the claimant’s illegal activity.
   • Common in cases where harm results from shared criminal conduct.
2. Case Example:
   • Pitts v Hunt (1990):
     • A motorcyclist injured during reckless driving while intoxicated was denied recovery.

Self-Defence

1. Definition:
   • Allows reasonable force to protect oneself, property, or others.
   • Force must be proportional to the threat.
2. Case Examples:
   • Cockroft v Smith (1705):
     • Biting off a finger in response to a minor attack was deemed excessive.
   • Revill v Newbery (1996):
     • Shooting an intruder resulted in reduced damages for contributory negligence but still imposed liability for excessive force.

Evaluation of Defences

1. Strengths:
   • Provides flexibility to address varying degrees of culpability.
   • Promotes fairness by recognizing shared responsibility in harm.
2. Challenges:
   • Overlap between certain defences (e.g., volenti and contributory negligence) can confuse legal arguments.
   • Policy considerations may lead to inconsistent application.
3. Modern Trends:
   • Increasing emphasis on proportionality and fairness, especially in areas like self-defence and contributory negligence.
