EXPLANATION / SCOPE

A successful plea of contributory negligence results in apportionment of blame between the parties and consequently apportionment of liability or damages. The plaintiff’s recovery is reduced by the percentage of their own fault. The defence does not bar recovery entirely but reduces it. The principle is based on the Law Reform (Contributory Negligence) Act. The court assesses the relative fault of each party. The apportionment is mandatory once contributory negligence is proved. The defendant remains liable for the portion of damage attributable to their fault. The plaintiff cannot recover for the portion caused by their own negligence. The apportionment must be just and equitable. The burden is on the defendant to prove the plaintiff’s share of responsibility.
