Contributory Negligence
What is the Contributory Negligence?
A common law defense that completely bars a plaintiff's recovery if the plaintiff's own negligence contributed in any degree to the injury. Only a handful of US jurisdictions still follow this rule.
Definition
Contributory negligence is the traditional common law defense that completely bars a plaintiff from recovery if the plaintiff's own negligence was a contributing cause of the injury, no matter how slight the plaintiff's fault compared to the defendant's. Under this all-or-nothing approach, even a plaintiff who is only 1% at fault is denied any recovery, while a defendant who is 99% at fault escapes all liability.
The doctrine has deep roots in English common law, originating in Butterfield v. Forrester. The harsh results of the doctrine led courts to develop ameliorative sub-doctrines, including the last clear chance doctrine, which allowed a contributorily negligent plaintiff to recover if the defendant had the last clear chance to avoid the harm but failed to do so. The doctrine of last clear chance effectively created an exception that prevented the most unjust outcomes.
Today, contributory negligence as a complete bar has been rejected by the vast majority of American jurisdictions in favor of comparative negligence. Only a small number of states (Alabama, Maryland, North Carolina, Virginia, and the District of Columbia) still follow the contributory negligence rule. However, the concept remains important for exam purposes because students must understand it historically, recognize which jurisdictions still apply it, and compare it with comparative negligence systems. The Restatement (Third) of Torts has abandoned contributory negligence as a complete bar in favor of comparative responsibility.
Key Elements
- 1The plaintiff failed to exercise reasonable care for their own safety
- 2The plaintiff's negligence was a contributing cause of the injury
- 3The plaintiff's fault, however slight, is sufficient to bar all recovery
- 4The defendant bears the burden of proving the plaintiff's contributory negligence
- 5The last clear chance doctrine may override the bar in some jurisdictions
Landmark Cases
Butterfield v. Forrester
11 East 60 (K.B. 1809)
Established the doctrine of contributory negligence as a complete bar to recovery in the common law.
Davies v. Mann
10 M. & W. 546 (1842)
Created the last clear chance doctrine, allowing a contributorily negligent plaintiff to recover if the defendant had the final opportunity to avoid the harm.
Li v. Yellow Cab Co.
13 Cal.3d 804 (1975)
Rejected contributory negligence as a complete bar and adopted comparative negligence, marking a major shift in American tort law.
Exam Tips
- If the exam specifies a contributory negligence jurisdiction, apply the complete bar rule and then analyze last clear chance as a potential exception.
- Be prepared to compare contributory negligence with both pure and modified comparative negligence and explain the policy arguments for and against each.
- Watch for fact patterns where the plaintiff is only slightly at fault — this highlights the harshness of the contributory negligence rule and invites policy discussion.
Common Mistakes to Avoid
- Applying contributory negligence in a comparative negligence jurisdiction — always check which system the jurisdiction uses before analyzing.
- Forgetting the last clear chance doctrine, which is the primary ameliorative mechanism under contributory negligence.
- Conflating contributory negligence (a plaintiff defense issue) with comparative fault apportionment — they are fundamentally different frameworks.
Memory Aid
Any fault = no vault. Under contributory negligence, even 1% fault locks the plaintiff out of recovery entirely.
