Whether res ipsa loquitur could be used to impose liability on several hotel guests when a cigarette caused a hotel-room fire but the evidence did not show which guest's cigarette caused it.
Holding
No. Res ipsa loquitur did not apply because Fireman's Fund failed to show that any respondent, individually or jointly, had exclusive control of the cigarette that started the fire.
Reasoning
Under Nevada's rule, res ipsa loquitur requires that the event ordinarily would not occur without negligence, that the injury-causing agency or instrumentality was within the defendant's exclusive control, and that the plaintiff did not voluntarily cause or contribute to the event. The insurer could not satisfy the exclusive-control requirement.
The hotel room was not shown to have been under the guests' exclusive control at the relevant time. The hotel possessed 18 keys to the room, and the record did not establish whether hotel staff or anyone else entered after the guests departed and before the fire was discovered.
More importantly, the relevant instrumentality was the particular cigarette that ignited the fire. Although all four respondents smoked in the room and each person exclusively controlled his or her own cigarette, there was no evidence identifying which cigarette caused the fire. Thus, there was no evidence that any particular respondent controlled the instrumentality responsible for the damage.
The Court recognized that some decisions, most notably Ybarra v. Spangard, permit res ipsa loquitur against multiple defendants despite uncertainty over which defendant was negligent. Those cases generally involved a known injury-causing instrumentality for which each defendant had some responsibility, or the unusual setting of an unconscious patient unable to identify either the actor or instrumentality. This hotel-fire case did not fit those limited circumstances.
Where several independent defendants might have caused the injury and the plaintiff cannot identify the responsible person, the more common rule rejects res ipsa loquitur. Applying the doctrine here would improperly force potentially innocent guests to disprove responsibility despite no evidence indicating which of them controlled the cigarette that started the fire.
