Negligence – Defences (Comprehensive Notes)

Topic: Defences to an action in negligence.
Key idea: Even when a plaintiff (Pf) proves duty, breach and causation, a defendant (Df) may invoke specific defences that partially or totally exclude liability.
Three main defences covered:
- Contributory Negligence.
- Volenti Non Fit Injuria (Consent).
- Inevitable Accident (including Act of God situations).

Definition
- Pf, through lack of reasonable care for their own safety/property, contributes to the harm suffered.
- Historically a complete bar to recovery; now generally a partial defence with apportionment of damages.

Rule: Any fault by Pf barred recovery entirely.
Rationale: The law should not protect those failing to protect themselves.
Key case: Butterfield v Forrester (1809)
- Df obstructed road; Pf riding fast at dusk hit pole.
- Held: Pf’s own negligence barred claim; Df completely absolved.
"Last Opportunity" refinement: Davies v Mann (1842)
- Pf’s donkey tied on road; Df could have avoided collision.
- Last negligent actor (Df) held fully liable despite Pf’s earlier negligence.

UK: Law Reform (Contributory Negligence) Act 1945 s.1(1).
Malaysia: Civil Law Act 1956 s.12 (mirrors UK wording).
- Court does not defeat claim; instead reduces damages to a "just and equitable" extent.
- Damages reduction proportional to Pf’s share of responsibility.

Pf failed to take proper care for own safety (unreasonable behaviour).
The failure was a contributing factual cause of the damage.
- No need for Pf to owe a duty to Df; focus is on Pf’s self-regarding duty of prudence.

Jones v Livox Quarries [1952]
- Worker standing on tow-bar crushed; Pf held $20\%$ to blame for disobeying rules.
- Lord Denning: Foreseeability of harm to oneself mirrors foreseeability to others.
Lai Yew Seong v Chan Kim Sang [1987]
- Rear-end collision; Pf held $100\%$ contributory negligent.
Wong Fook v Abdul Shukur [1991]
- Seat-belt non-use reduces recovery only if Pf was the driver; full compensation if mere passenger.
Sundram v Arjunan [1991]
- Motorcyclist lying on road hit by car; Df failed to prove Pf’s position caused injury — no reduction.

Guiding test: Would a normal child of Pf’s age act similarly?
Very young children rarely at fault.
Key cases:
- Yachuk v Oliver Blais [1949]: 9-year-old bought petrol, burned; no CN — child lacked appreciation of risk.
- Gough v Thorns [1966]: 13-year-old beckoned across road; no CN — could not be expected to double-check traffic.
- Mohamad Safuan v Mohd Ridhuan [1994]: 4-year-old knocked by motorcycle; court rejected CN, emphasised higher duty on motorist.
- Jag Singh v Toong Fong Omnibus [1962] & Tey Siew Goh v Tay Tian Soo [1965]: Older child passengers/pedestrians apportioned $50\%$ fault where behaviour negligent.

Literal meaning: "To one who volunteers, no harm is done."
Nature: Complete defence — total bar to Pf’s claim.
Requirement: Pf freely and voluntarily agrees, with full knowledge, to exempt Df from legal consequences of negligence.

Voluntary participation/decision.
- Must be free choice; coercion, employment pressure, or rescue scenarios negate voluntariness.
Agreement/Consent to waive right of action.
- May be express (contract, notice) or implied from conduct.
- Mere knowledge of risk is insufficient (see Nettleship).
Full Knowledge of Nature & Extent of Risk.
- Pf must appreciate not just physical risk but lack of reasonable care that may produce it.

Df bears onus to establish Pf’s awareness and consent.
Commonly argued in:
- Sporting spectators and participants.
- Passengers accepting lifts from obviously intoxicated drivers.
- Experienced employees ignoring safety instructions.

Smith v Charles Baker & Sons (1891)
- Worker knew stone-hoist danger but did not consent to employer’s negligence; defence failed.
Nettleship v Weston (1971)
- Learner-driver case; Lord Denning: Knowledge ≠ consent; must agree to waive claim.
Wooldridge v Sumner (1963)
- Photographer at horse show injured; held to consent to reasonable sporting risks, but not to negligent conduct beyond sport’s demands.
Imperial Chemical Industries v Shatwell (1965)
- Shotfirer brothers ignored employer’s instructions; full knowledge + voluntary defiance = volenti succeeded.
Morris v Murray (1991)
- Passenger accepted flight with drunk pilot (≈17 whiskies); risk "so glaring" that consent inferred; defence succeeded.

Definition: Harm occurs despite Df exercising reasonable care; accident unavoidable and unforeseeable.
May involve latent defects not discoverable by reasonable inspection or external acts of God.

Che Jah binti Mohamed Ariff v C.C. Scott [1952]
- Latent brake defect after professional repair; car crashed into stationary vehicle; court held Df not negligent — inevitable accident.

Contributory Negligence → Partial defence reducing damages proportionally.
- Courts emphasise just & equitable apportionment.
- Last Opportunity Rule largely superseded by apportionment statutes.
Volenti → Complete defence; rarely succeeds unless facts clearly show voluntary waiver.
- High threshold: Pf must accept legal risk in addition to physical risk.
Inevitable Accident → Complete defence but narrow; Df must show no negligence whatsoever.

Shift from harsh common-law bar to proportionate liability reflects societal view that minor fault should not erase recovery.
Volenti balances autonomy (freedom to take risk) with deterrence; courts wary of presumed consent in employment or unequal relations.
Protection of children: Courts adopt flexible, child-centric standards recognising developmental limitations.

Civil Law Act 1956 s.12 — Apportionment in contributory negligence.
Road Traffic & employment safety regulations influence standard of care and assessment of fault.

Damages reduction: \text{Damages Payable} = (1 - \text{Pf\% Fault}) \times \text{Total Loss}
- Example: $RM80,000\; \times \; (1 - 0.25) = RM60,000$ .
Percentages used in case law apportionments: $20\%$ , $25\%$ , $50\%$ , $75\%$ , $100\%$ .

Memorise statutory wording ("just and equitable" apportionment).
Distinguish between knowledge of risk and consent to negligence.
For problem questions:
1. Identify possible Pf fault – quantify percentage.
2. Test for volenti – check voluntariness, consent, knowledge.
3. Assess foreseeability & preventability for inevitable accident.
Use case law to analogise facts; emphasise quotes from Lord Denning on foreseeability and child CN standards.
