The defendant, Forrester, placed a pole or bar across part of a public roadway while undertaking repairs to his residence, thereby creating a partial obstruction in the street. At twilight, the plaintiff, Butterfield, rode his horse "violently" or at an excessive speed along the same road and struck the obstruction, suffering injury. A witness testified that the obstruction was visible from a substantial distance (about 100 yards) and could have been avoided had the plaintiff been exercising ordinary care. At trial before Bayley, J., the jury was instructed that if the plaintiff could have avoided the accident by exercising ordinary care, he could not recover. The jury returned a verdict for the defendant, and the plaintiff sought to set aside the verdict.
Whether a plaintiff who fails to exercise ordinary care and thereby contributes to his own injury may recover damages from a defendant whose negligence created a hazard in the roadway.
A plaintiff may not recover for injuries if his own lack of ordinary care proximately contributed to the harm. One party's negligence does not excuse the other's duty to use ordinary care for his own safety; if by exercising ordinary care the plaintiff could have avoided the injury, recovery is barred. This is the classic doctrine of contributory negligence.
The court affirmed the verdict for the defendant, holding that the plaintiff's failure to use ordinary care—contributing to the injury—barred recovery, notwithstanding the defendant's negligence in obstructing the roadway.
The Court of King's Bench reasoned that negligence liability is reciprocal: while the defendant was at fault for creating an obstruction in a public way, the law also requires the plaintiff to use ordinary care to protect himself from obvious or avoidable hazards. The evidence supported the inference that the plaintiff was riding with undue speed at twilight and, according to a witness, could have seen and avoided the obstruction from a considerable distance had he acted with ordinary caution. Thus, the plaintiff's lack of care was a proximate, cooperating cause of the accident. Because his negligence contributed to the injury, the plaintiff could not recover. The court approved the trial judge's instruction to the jury that a defendant's negligence does not dispense with the plaintiff's duty of ordinary care; if the accident could have been avoided by such care, the verdict must be for the defendant. In short, where the plaintiff's negligence contributes to the harm, contributory negligence operates as a complete bar.
Butterfield v. Forrester is the seminal authority for the contributory negligence doctrine in Anglo-American tort law. It frames the plaintiff's duty of self-care and established the traditional common-law rule that any contributory fault bars recovery entirely. Although many jurisdictions later adopted comparative negligence to mitigate this harsh result, Butterfield remains essential to understanding the historical baseline, to spotting contributory negligence defenses on exams and in practice, and to appreciating later doctrinal developments such as the last clear chance doctrine and comparative fault statutes.
Butterfield v. Forrester sets the foundational rule that a plaintiff must exercise ordinary care for his own safety; failure to do so that contributes to the injury precludes recovery. The case underscores that negligence analysis examines both parties' conduct and that a defendant's wrongful act does not negate the plaintiff's duty of self-protection.
