What does res ipsa loquitur mean in medical negligence cases?

• A. It is a doctrine that requires direct proof of breach.
• B. The thing speaks for itself — the evidence strongly suggests negligence; not needing direct proof of breach.
• C. It is used only when patient consent is present.
• D. It is a doctrine that requires no evidence of neglect.

Answer: (B)

Res ipsa loquitur means “the thing speaks for itself.” In medical negligence, it describes a situation where the injury or harm is of a type that ordinarily would not occur without negligence, the instrumentality or condition causing the injury was under the defendant’s exclusive control, and the patient did not contribute to the harm. Because the circumstances themselves strongly suggest negligence, direct proof of a specific breach isn’t required at the outset; the evidence shifts the burden to the defendant to show there was no breach or to provide an alternative explanation.

That’s why the best description is that the thing speaks for itself — the evidence strongly suggests negligence and does not require direct proof of breach. It is not about patient consent, and it does involve an inference of negligence based on the circumstances, not a claim that no evidence is needed at all.
