In some common law jurisdictions, contributory negligence is a defense to a tort claim based on negligence. If it is available, the defense completely bars plaintiffs from any recovery if they contribute to their own injury through their own negligence.
Because the contributory negligence doctrine can lead to harsh results, many common law jurisdictions have abolished it in favor of a "comparative fault" or "comparative negligence" approach. A comparative negligence approach reduces the plaintiff's damages award by the percentage of fault the fact-finder assigns to the plaintiff for their own injury. For example, if a jury thinks the plaintiff is 30% at fault, the plaintiff's damages award will be reduced by 30%.
