250 N.Y. 479, 166 N.E. 173 (N.Y. 1929)
Murphy v. Steeplechase Amusement Co.
Does a patron who voluntarily rides an amusement device with obvious, inherent risks assume those risks as a matter of law, thereby barring recovery for injuries absent proof that the operator concealed a danger or unreasonably increased the risk?
A participant in a sport or amusement "accepts the dangers that inhere in it so far as they are obvious and necessary." The operator owes a duty not to create or conceal unreasonable risks or defects that materially enhance the inherent dangers. Absent evidence of a hidden defect, negligent operation, or an unreasonable increase in risk beyond what is obvious and essential to the activity, the plaintiff's voluntary participation constitutes primary assumption of risk and bars recovery.
Yes. The plaintiff assumed the inherent, obvious risks of The Flopper as a matter of law and could not recover. The Court of Appeals held that, in the absence of proof of a concealed defect or negligent enhancement of the danger, the defendant was not liable for injuries arising from the very hazards that defined the ride.
Murphy anchors the modern doctrine of primary assumption of risk in sports and recreational settings. It distinguishes inherent and obvious dangers—which negate a duty to protect or warn—from concealed or unreasonably increased dangers, which remain actionable. Although many jurisdictions now use comparative fault to subsume some forms of assumption of risk, Murphy's core idea persists: duty is context-specific, and operators are not insurers against the essential hazards that make activities what they are. The case is frequently cited in New York and beyond to limit liability for injuries in sports, recreational activities, and amusement settings, while preserving claims for hidden defects or negligent enhancement of danger.
