res ipsa loquitur
Latin: "the thing speaks for itself." This is a legal doctrine used to assess
liability (often against professionals) when there is no evidence as to how
an injury took place. 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.
