Res ipsa loquitor – The thing speaks for itself.
Res Ipsa Loquitur — Meaning and Principle
Latin Meaning:
Res ipsa loquitur literally means “The thing speaks for itself.”
What is Res Ipsa Loquitur?
It is a legal doctrine used in tort law, specifically in negligence cases, where the facts of the case allow the court to infer negligence from the mere occurrence of the accident or injury, even without direct evidence proving the defendant's negligence.
In other words, the circumstances are such that the accident or injury would not have occurred “but for” someone's negligence, and the cause of the injury is under the defendant's control.
Why is this Doctrine Important?
It helps plaintiffs prove negligence when direct evidence is not available.
Shifts the burden of proof to the defendant to show that there was no negligence.
Protects injured parties in cases where facts strongly imply negligence.
Essential Conditions for Applying Res Ipsa Loquitur
Accident of a kind which ordinarily does not occur in the absence of negligence.
The event must be such that it would not happen without someone's negligence.
The instrumentality or thing causing the injury was under the defendant’s control.
The defendant had exclusive control over the cause of the accident.
The injured party did not contribute to the cause of the injury.
The plaintiff was not negligent or responsible for the accident.
Explanation through an Example
Suppose a pedestrian is injured by a falling object from a building under repair. The injured person cannot prove exactly how the object fell, but since such an accident does not normally happen without negligence, and the repair work is controlled by the building owner or contractor, negligence is inferred under res ipsa loquitur.
Legal Effect
The plaintiff does not need to prove specific negligence.
The defendant must prove that they took all reasonable care and are not negligent.
If the defendant fails to do so, they are held liable.
Landmark Case Law Illustrating Res Ipsa Loquitur
Scott v. London & St. Katherine Docks Co. (1865) 3 H & C 596 (UK case but often cited in Indian courts)
Facts: A barrel of sugar fell from the defendant’s warehouse and injured the plaintiff.
Held: Since barrels do not fall without negligence, and the warehouse was under the defendant’s control, negligence was presumed.
Brahma Prakash Sharma v. Nair Service Society Ltd. AIR 1968 SC 1161 (India)
Facts: The plaintiff was injured by a collapsing pillar of a building maintained by the defendant.
Held: The Court applied the principle of res ipsa loquitur, holding that since the injury would not have happened without negligence, and the defendant had control over the building, negligence was presumed.
State of Punjab v. Gurdial Singh AIR 1963 SC 1295
Facts: A person was injured due to a falling part of a public works construction.
Held: The Court held that the doctrine of res ipsa loquitur applies when the accident or injury is of such nature that it speaks for itself, and negligence is presumed unless the defendant disproves it.
