Background
Michael Ristaino visited Urban Air Downingtown, an indoor trampoline park operated through several related entities. While using a trampoline, he landed and suffered injuries. Ristaino later sued the Urban Air defendants for negligence, alleging that the trampoline bed was worn out and that the facility had failed to inspect, maintain, and replace it in accordance with its own procedures and industry standards.
The defendants sought summary judgment under Pennsylvania’s “no-duty” rule. That doctrine limits liability for risks that are common, frequent, expected, and inherent in a sport or amusement activity. The Chester County Court of Common Pleas accepted the argument. It emphasized Ristaino’s acknowledgment that trampoline use can cause serious or fatal physical injuries and dismissed his complaint without a trial.
Ristaino appealed, arguing that the trial court had defined the risk at too high a level of generality. He did not claim merely that jumping on a trampoline can produce a bad landing. His testimony and expert materials attributed the accident to a deteriorated trampoline bed and other maintenance deficiencies. The appeal therefore asked whether participation in an amusement activity eliminates a proprietor’s ordinary duty to address defective equipment.
The Court’s Holding
Judge Dubow wrote for the Superior Court and reversed. Pennsylvania’s no-duty rule depends on the source of the particular risk, not simply on whether the plaintiff was participating in a sport or amusement when injured. A court must distinguish the ordinary risks inherent in the activity from added hazards created by a defendant’s conduct or by a condition that participants would not reasonably anticipate.
The panel drew on cases involving a spectator struck by a baseball and a football spectator trampled by aggressive fans. A foul ball is an ordinary and expected feature of baseball, but crowd-control failures are not an inevitable part of watching football. In the same way, the possibility of an awkward landing may accompany trampolining, but a worn-out jumping surface is not common, frequent, and expected at every trampoline park.
Viewed in Ristaino’s favor as the party opposing summary judgment, the evidence supported a finding that deterioration and deficient maintenance caused his injury. The trial court had not separately analyzed that theory before applying the no-duty rule. Because defective equipment presented an unforeseeable and unanticipated risk rather than an inherent one, the rule did not bar the negligence claims as a matter of law. The Superior Court remanded the case for further proceedings without deciding whether Ristaino would ultimately prove breach or causation.
Key Takeaways
- Pennsylvania’s no-duty rule turns on the specific risk that caused the injury, not merely the plaintiff’s participation in a sport or amusement.
- Ordinary jumping risks may be inherent in trampolining, but a worn-out trampoline bed is not an expected feature of the activity.
- A proprietor cannot obtain summary judgment under the no-duty rule when evidence attributes the accident to maintenance or equipment defects.
- Rejection of the no-duty defense does not establish negligence; the plaintiff must still prove duty, breach, causation, and damages on remand.
Why It Matters
Ristaino gives Pennsylvania premises-liability lawyers a clean framework for recreational-injury cases. The decisive question is how the risk is characterized. Defendants will often describe the danger broadly as falling, collision, or physical contact. Plaintiffs should identify the allegedly negligent condition more precisely and produce evidence showing why that condition is not a normal component of the activity.
For trampoline parks, gyms, sports venues, and other amusement operators, participant acknowledgments of general danger do not necessarily dispose of negligent-maintenance claims. Inspection schedules, replacement criteria, internal policies, and industry standards may determine whether the claimed hazard is inherent or introduced by the operator. At summary judgment, courts must evaluate that evidence in the nonmovant’s favor rather than treating every injury during recreation as categorically assumed.
The published decision also preserves the boundary between a limited-duty doctrine and ordinary negligence law. Pennsylvania courts will protect operators from liability for truly inherent risks, but the doctrine does not license defective equipment. Counsel should build the record around the precise mechanism of injury and separate unavoidable aspects of the activity from conditions that reasonable maintenance could have prevented.
