res ipsa loquitur
Res ipsa loquitor is Latin for the "the thing speaks for itself." This is a legal doctrine used to assess liability (often against professionals) when there is no evidence of negligence with respect to how an injury took place.
Additional Information
For instance, if a sponge is inadvertently left in a patient's stomach, the doctrine of res ipsa loquitur is typically invoked to establish liability because such an event is presumed not to occur in the absence of negligence.
