Res Ipsa Loquitur
The legal concept that some acts are so obviously negligent that no further explanation is necessary to prove legal liability. A res ipsa loquitur case ordinarily requires one to show that an act usually would not occur without negligence, that the act probably was the result of negligence, that the defendant caused the negligence, and that the plaintiff did not contribute to it. A res ipsa loquiture case contrasts with a prima facie case, which requires more evidence to prove liability. The phrase "res ipsa loquitur" is Latin for "the thing speaks for itself."
