What is 'Res Ipsa Loquitur'?
Historical Background
Key Points
10 points- 1.
The first requirement for applying 'Res Ipsa Loquitur' is that the accident must be of a kind that ordinarily does not occur in the absence of someone's negligence. This means the event is so unusual that it strongly suggests someone messed up. For example, a surgical instrument left inside a patient after surgery is the kind of event that almost never happens without negligence.
- 2.
The second requirement is that the instrumentality or agency causing the injury must have been under the exclusive control of the defendant. This means the defendant had sole responsibility for the thing that caused the harm. For example, if a patient contracts an infection while in a hospital, 'Res Ipsa Loquitur' might apply if the hospital had exclusive control over the sanitation and hygiene practices.
- 3.
The third requirement is that the injury must not have been due to any voluntary action or contribution on the part of the plaintiff. The injured person shouldn't have done anything to cause or contribute to their own injury. For example, if a person trips and falls on a clearly marked wet floor, 'Res Ipsa Loquitur' likely wouldn't apply because their own actions contributed to the injury.

Frequently Asked Questions
61. In an MCQ about 'Res Ipsa Loquitur', what is the most common trap examiners set regarding the burden of proof?
The most common trap is suggesting that 'Res Ipsa Loquitur' automatically wins the case for the plaintiff. It doesn't. It only *shifts* the burden of proof to the defendant to prove they were NOT negligent. The plaintiff still needs to initially demonstrate the three key provisions are met. Examiners often present options where 'Res Ipsa Loquitur' guarantees a win, which is incorrect.
Exam Tip
Remember: 'Res Ipsa Loquitur' = Shift, not automatic win. Look for answer choices that emphasize 'burden shift' rather than 'automatic victory'.
2. Why do students often confuse the 'exclusive control' requirement of 'Res Ipsa Loquitur' with vicarious liability, and what is the correct distinction?
Students confuse them because both involve one party being held responsible for the actions of another. However, 'exclusive control' in 'Res Ipsa Loquitur' means the defendant had sole control over the *instrumentality* that caused the injury. Vicarious liability, on the other hand, means one party is liable for the *negligent actions* of another, even if they didn't have control over the instrumentality. For example, a hospital having exclusive control over its sanitation practices (leading to an infection) is 'Res Ipsa Loquitur'. An employer being responsible for the negligent driving of their employee is vicarious liability.
