Arizona's Legal Framework for Trampoline Injuries
Three legal theories come up most often after a trampoline accident in Arizona, and more than one can apply to the same fall.
The first is premises liability: the responsibility of whoever owns or controls a property for injuries caused by its condition or by how it is run. The law asks four things. Did the party owe the injured person a duty of care? Did it breach that duty? Did the breach cause the injury? Did the injury cause damages? An injury alone does not answer any of these questions.
The second is product liability, which concerns a trampoline, mat, spring, net or pad alleged to be defective. Here the law asks whether there was a defect and whether the defect caused the injury. An accident does not prove a defect.
The third is negligent supervision. This is the claim that someone responsible for watching over jumpers failed to use reasonable care in doing so. It most often arises at trampoline parks, birthday parties and organized programs.
Two Arizona statutes shape how all three theories work. Under section 12-2505 of the Arizona Revised Statutes, contributory negligence and assumption of risk are "in all cases a question of fact and shall at all times be left to the jury." If the jury applies either defense, "the claimant's action is not barred, but the full damages shall be reduced in proportion to the relative degree of the claimant's fault which is a proximate cause of the injury or death." That rule has one stated exception: there is no comparative negligence for a claimant who "intentionally, wilfully or wantonly caused or contributed to the injury or wrongful death." The statute also counts fault "imputed or attributed to a claimant by operation of law."
The second statute is the recreational-use rule in section 33-1551 of the Arizona Revised Statutes. Under it, an owner, easement holder, lessee, tenant, manager or occupant of premises is not liable to a recreational user or educational user unless that party "was guilty of wilful, malicious or grossly negligent conduct that was a direct cause of the injury." The same section says it "does not create a duty of care or basis of liability."
Which of these rules governs a given injury depends on the facts: where it happened, who controlled the equipment and what kind of visitor the injured person was.
