Doctrine of res ispa loqitur.- “Literally, res ipsa loqitur means the thing speaks for itself. It is the rule that that the fact of the occurrence of an injury, taken with the surrounding circumstance, may permit an inference or raise a presumption of negligence, or make out a plaintiff’s prima facie case, and present a question of fact for defendant to meet with an explanation”[1]
“Res ipsa loquitur is literally translated as “the thing or the transaction speaks for itself.” The doctrine res ipsa loquitur means that “where the thing which causes injury is shown to be under the management of the defendant, and the accident is such as in the ordinary course of things does not happen if those who have the management use proper care, it affords reasonable evidence, in the absence of an explanation by the defendant, that the accident arose from want of care.”[2] It is simply “a recognition of the postulate that, as a matter of common knowledge and experience, the very nature of certain types of occurrences may justify an inference of negligence on the part of the person who controls the instrumentality causing the injury in the absence of some explanation by the defendant who is charged with negligence. It is grounded in the superior logic of ordinary human experience and on the basis of such experience or common knowledge, negligence may be deduced from the mere occurrence of the accident itself.[3]
Requisites for application of res ipsa loquitur. – “The requisites for the applicability of the doctrine of res ipsa louitur are (1) the occurrence of an injury; (2) the thing which caused the injury was under the control and management of the defendant; (3) the occurrence was such that in the ordinary course of things. Would not have happened if those who had control or management used proper care; and (4) the absence of explanation by the defendant. “[4]
Applicability of doctrine of res ipsa loquitur in medical malpractice cases. – Medical malpractice cases do not escape the application of this doctrine. Thus, res ipsa loquitur has been applied when the circumstances attendant upon the harm are themselves of such a character as to justify an inference of negligence as the cause of that harm. The application of res ipsa loquitur in medical negligence cases presents a question of law since it is a judicial function to determine whether a certain set of circumstances does, as a matter of law, permit a given inference.
Although generally, expert medical testimony is relied upon in malpractice suits to prove that a physician has done a negligent act or that he has deviated from the standard medical procedure, when the doctrine of res ipsa loquitur is availed by the plaintiff, the need for expert medical testimony is dispensed with because the injury itself provides the proof of negligence. The reason is that the general rule on the necessity of expert testimony applies only to such matters clearly within the domain of medical science, and not to matters that are within the common knowledge of mankind which may be testified to by anyone familiar with the facts. Ordinarily, only physicians and surgeons of skill and experience are competent to testify as to whether a patient has been treated or operated upon with a reasonable degree of skill and care. However, testimony as to the statements and acts of physicians and surgeons, external appearances, and manifest conditions which are observable by any one may be given by non-expert witnesses. Hence, in cases where the res ipsa loquitur is applicable, the court is permitted to find a physician negligent upon proper proof of injury to the patient, without the aid of expert testimony, where the court from its fund of common knowledge can determine the proper standard of care. Where common knowledge and experience teach that a resulting injury would not have occurred to the patient if due care had been exercised, an inference of negligence may be drawn giving rise to an application of the doctrine of res ipsa loquitur without medical evidence, which is ordinarily required to show not only what occurred but how and why it occurred. When the doctrine is appropriate, all that the patient must do is prove a nexus between the particular act or omission complained of and the injury sustained while under the custody and management of the defendant without need to produce expert medical testimony to establish the standard of care. Resort to res ipsa loquitur is allowed because there is no other way, under usual and ordinary conditions, by which the patient can obtain redress for injury suffered by him.
Thus, courts of other jurisdictions have applied the doctrine in the following situations: leaving of a foreign object in the body of the patient after an operation, injuries sustained on a healthy part of the body which was not under, or in the area, of treatment, removal of the wrong part of the body when another part was intended, knocking out a tooth while a patient’s jaw was under anesthetic for the removal of his tonsils, and loss of an eye while the patient plaintiff was under the influence of anesthetic, during or following an operation for appendicitis, among others.
Nevertheless, despite the fact that the scope of res ipsa loquitur has been measurably enlarged, it does not automatically apply to all cases of medical negligence as to mechanically shift the burden of proof to the defendant to show that he is not guilty of the ascribed negligence. Res ipsa loquitur is not a rigid or ordinary doctrine to be perfunctorily used but a rule to be cautiously applied, depending upon the circumstances of each case. It is generally restricted to situations in malpractice cases where a layman is able to say, as a matter of common knowledge and observation, that the consequences of professional care were not as such as would ordinarily have followed if due care had been exercised. A distinction must be made between the failure to secure results, and the occurrence of something more unusual and not ordinarily found if the service or treatment rendered followed the usual procedure of those skilled in that particular practice. It must be conceded that the doctrine of res ipsa loquitur can have no application in a suit against a physician or surgeon which involves the merits of a diagnosis or of a scientific treatment. The physician or surgeon is not required at his peril to explain why any particular diagnosis was not correct, or why any particular scientific treatment did not produce the desired result. Thus, res ipsa loquitur is not available in a malpractice suit if the only showing is that the desired result of an operation or treatment was not accomplished. The real question, therefore, is whether or not in the process of the operation any extraordinary incident or unusual event outside of the routine performance occurred which is beyond the regular scope of customary professional activity in such operations, which, if unexplained would themselves reasonably speak to the average man as the negligent cause or causes of the untoward consequence. If there was such extraneous intervention, the doctrine of res ipsa loquitur may be utilized and the defendant is called upon to explain the matter, by evidence of exculpation, if he could.
In order to allow resort to the doctrine, therefore, the following essential requisites must first be satisfied, to wit: (1) the accident was of a kind that does not ordinarily occur unless someone is negligent; (2) the instrumentality or agency that caused the injury was under the exclusive control of the person charged; and (3) the injury suffered must not have been due to any voluntary action or contribution of the person injured.”[5]
