To use the doctrine, the plaintiff must prove three factors: 1) the injury or harm suffered was of a type that usually does not occur in the absence of negligence; 2) the instrumentality of injury was in the exclusive control of the defendant; and 3) the injury occurred because of defendant\u2019s negligence. <\/p>\n<p>The doctrine of res ipsa loquitur is used to infer negligence if the defendant was more likely than not responsible. For example, if a patient becomes ill after medical treatment, the doctrine can be used to state that the defendant was negligent and the <a href=\"https:\/\/legalpedia.ai\/articles\/what-does-burden-of-proof-mean-in-the-court-of-law\/\">burden of proof<\/a> shifts to the defendant to prove otherwise.<\/p>\n<h2>Modern Examples of When Res Ipsa Loquitur Applies <\/h2>\n<p>When the doctrine of res ipsa loquitur applies, it is not always in the context of a courtroom.
