Facts
- Louise Giles worked as an elevator operator in the Powell Building in New Haven.
- While she was operating the elevator, a “compensation chain” in the shaft swayed excessively, became hooked on a rail bracket, then broke free, causing a violent event that injured her.
- Giles claimed Otis Elevator Company, the elevator installer and maintenance contractor, negligently failed to inspect, maintain, and repair the elevator and its parts, including the compensation chain.
- Giles lacked direct proof of a specific negligent act or omission by Otis and relied on res ipsa loquitur to permit an inference of negligence from the nature of the occurrence.
- The trial court directed a verdict for Otis, concluding the evidence was insufficient to submit negligence to the jury under res ipsa loquitur.
- The Appellate Court reversed, holding the res ipsa theory should have gone to the jury, and Otis sought further review.
Issues
- Whether the evidence was sufficient to permit a jury to infer Otis’s negligence under res ipsa loquitur for the elevator accident.
- Whether the “control” requirement for res ipsa loquitur was defeated because Giles was operating (using) the elevator when the incident occurred.
- Whether potential negligence by the plaintiff bars the use of res ipsa loquitur in a comparative negligence regime.
Decision
- The Supreme Court of Connecticut affirmed the Appellate Court.
- The court held Giles produced sufficient evidence to submit the negligence question to the jury under res ipsa loquitur.
- The court ruled that “exclusive control” is not absolute; the jury could reasonably find Otis’s control over maintenance and the relevant internal components was sufficient to support an inference of negligence.
- The court held res ipsa loquitur may apply even if the plaintiff’s negligence may have contributed to the injury; any plaintiff fault is addressed through comparative negligence rather than by barring the inference.
- The case was not resolved on liability; the court required that the res ipsa inference be available for jury determination rather than removed by directed verdict.
Legal Principles
- Res ipsa loquitur permits a factfinder to infer negligence from an occurrence when: (1) the type of event ordinarily does not occur without negligence in construction, inspection, or use; (2) the instrumentality’s inspection and use were sufficiently within the defendant’s control; and (3) the occurrence is not required to be wholly independent of plaintiff conduct when comparative negligence applies.
- “Exclusive control” is a practical, not literal, requirement; the question is whether the defendant’s responsibility and control make it reasonable to infer the defendant is the probable source of negligence.
- Under comparative negligence, possible plaintiff contribution to the accident does not categorically bar res ipsa loquitur; it bears on apportionment of fault.
Conclusion
The court held that an elevator operator injured by an internal mechanical failure could proceed to the jury on a res ipsa loquitur theory against the maintenance contractor, because control need not be absolute and comparative negligence permits the inference even when plaintiff fault is possible.
