RES IPSA LOQUITUR DE NOVO John H. Crabb* and Kenneth F.Johannson** I INTRODUCTION It has been said that the law of torts is tainted with a "besetting sin" of turning propositions of fact into rules of law.' If the law of torts does indeed do this-and does indeed thereby sin-such an activity undoubtedly reaches its apogee in the torts "doctrine" of res ipsa loquitur. Some eminent writers in the field of torts have turned a baleful eye on res ipsa loquitur and seem to regard it as a sinful habit from which the law of torts should be rescued. 2 At all events it is probably susceptible to the abuse that befalls many catchy labels and handles that are bandied about in legal jargon. Although it has been a phenomenon of the Anglo-American legal world for some time now, it has been a continual source of controversy and confusion. Certainly a major part of the difficulty in dealing with res ipsa loquitur stems from its character of being a mixture of substance and procedure. Indeed, it appears that this strong taint of procedure caused3 the first Restatement of Torts to ignore or avoid the subject altogether. And it has been in its procedural aspects that it has demonstrated its most divergent treatment among the various states. While the large majority of jurisdictions are said to give res ipsa loquitur the effect of creating a permissible inference of negligence based on circumstantial evidence, a dwindling minority deem that it creates a presumption of negligence, and still fewer courts find that it shifts the burden of proof * Associate Professor of Law, University of North Dakota; A.B., 1943, Uni- versity of Michigan; LL.B., 1948, Harvard University; M.A., 1954, University of Detroit. ** Member, Minnesota and North Dakota Bars; B.S.B.A., 1958, J.D., 1962, University of North Dakota. 1 Williams, The Application of the Contributory Negligence Act to Liability for Dangerous Premises, 13 CoNvEY.(n.s.) 411, 416 (1949), cited in Obcrst, Torts, ANN.

MAINE LAW REVIEW to the defendant. 4 And Michigan and South Carolina state they have formally rejected the concept altogether, but they in effect apply it under 4 other guises. a It is to be noted that these major divergences all refer to the procedural effect that is to be given to res ipsa loquitur, rather than to differences concerning the substantive bases upon which such procedural consequences are to be predicated. It seems that greater consistency is to be found in this substantive side of res ipsa loquitur, and that courts usually have about the same type of factual situation in mind when they are considering whether or not res ipsa loquitur is applicable. This seems to be true even though they may phrase the formula in various ways or may differ in their analysis of facts and application of the formula to them. The common underlying theme is the happening of an event injuring the plaintiff, which by its nature is sufficient to permit a jury to find the defendant liable. It appears that the second Restatement will be bolder than the first, and will grapple with this procedural and substantive tangle and undertake to state the doctrine. The language of the Tentative Draft for the second Restatement of Torts of concern to this discussion is as follows: It may be inferred that harm suffered by the plaintiff is caused by negligence of the defendant when (a) The event is of a kind which ordinarily does not occur in the absence of the defendant when (a) The event of a kind which ordinarily does not occur in the absence of negligence; (b) Other responsible causes, including the conduct of the plaintiff and third persons, are sufficiently eliminated by the evidence; and (c) The indicated negligence is within the scope of the defendant's duty to the plaintiff." 5 This may be taken as the latest statement by a widely respected authoritative source as to what res ipsa loquitur is. But the statement leaves room for interpretation and does not promise to still controversy and commentary. Res ipsa loquitur came to this present resting placeif that is indeed what it is-after undergoing some period of historical development. II HISTORICAL DEVELOPMENT One may speculate that the more up-and-coming of the ancient Romans occasionally said "Res ipsa loquitur" to one another, thereby 4 Ibid. 4a Numerous cases in these two jurisdictions have so stated. See, e.g., Pattison v. Coca-Cola Bottling Co., 333 Mich. 253, 52 N.W.2d 688 (1952); Shephard v. United States Fid. & Guar. Co., 233 S.C. 536, 106 S.E.2d 381 (1958). 5RESTATEMENT (SECOND), TORTS § 328D(1) (Tent. Draft No. 5, 1960). On the strictly procedural side, this section adopts the inference-of-negligence theory. RES IPSA adding wit and charm to many an otherwise dull conversation.! However, the phrase as it is significant to us is not an ancient maxim, but arose only about a century ago, long after people were supposed to have stopped speaking Latin unnecessarily. 6a Baron Pollock is generally credited with having embellished the field of torts with this phrase in 1863 in the picturesque old case of Byrne v. Boadle.7 However, it had appeared two and a half centuries earlier in the usury case of Roberts v. Tremaynes where the court ruled a ury's verdict was not necessary to establish the invalidity of an obviously usurious agreement because "res ipsa loquitur." And, even in the field of torts itself, the seed may be said to have been strewn in 1806 in Christie v. Griggs.9 There, evidence that the plaintiff was riding in the defendant's coach, that there was an accident, and that the plaintiff was injured, was allowed as a rebuttable presumption of negligence. After a prolonged gestation of some fifty-seven %ears, the doctrine was born in Byrne v. Boadle. Baron Pollock seems to have suggested a name when he casually uttered this Latinism in his colloquy with counsel, rather than in his opinion itself. In 1865 in the London Docks Case, Chief Justice Erle formulated the much quoted statement that if the thing is under the "management of the defendant or his servants 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 explanation by the defendants, that the accident arose from want of care." 10 The formal baptism of the infant as res ipsa loquitur appears to have occurred one year later."' Two later cases illustrate the direction the English courts pursued in applying the doctrine. In one, a brick fell from a railway bridge and injured the plaintiff shortly after a train had passed. The court held that 6 However, it was used on weightier occasions.

MAINE LAW REVIEW res ipsa loquitur was applicable in that there was a prima facie case of negligence imputed to the defendant and it was incumbent upon the defendant to show that he had used reasonable care and diligence.12 In another, a passenger of a train leaned upon a door to see the lights of the next station, the door opened, and the plaintiff fell. There was no further evidence of negligence. The court imputed negligence to the company for failing to fasten the door adequately even though there was no evidence introduced of that fact. 13 Some significance may be attached to the fact that both defendants were railroad companies. Probably the first clear statement of the principle in the United States was in Mullen v. St. John 4 where the court held that it was reasonable to presume negligence in the absence of explanation when the cause of the accident is one which does not ordinarily happen in the case of nonnegligent conduct. But it was not enough to prove the accident and the also had to be such that the injury; but the manner and circumstances 15 jury could reasonably infer negligence. A public policy favorable to plaintiffs seemed to be the great influence causing the doctrine to become firmly entrenched in this country. An examination of some of the early cases reveals that the defendant invariably was a common carrier that was required to exercise extraordinary care.18 The reason advanced for the application of res ipsa loquitur was that by the very nature of the circumstances the passenger rarely knows of the cause of the injury, while the carrier has the means to show the facts and, if free from blame, can exonerate itself.' 7 This phase of the early development of res ipsa loquitur links up with the widespread judicial policy of the nineteenth century to favor local plaintiffs at the expense of the railroads that were so strangely and obstreperously spreading themselves across a theretofore placid countryside. Even at the turn of the century writers expressed concern over the plaintiff's "hardship" in proving a negligence case.' 8 The doctrine spread rapidly into other areas and factual situations 12Kearney v.

RES IPSA after obtaining a firm foundation in carrier cases.19 The later cases con- sistently reflected situations stemming from increased usage of mechanization where the defendant was at a great, if not total, advantage over the plaintiff in the extent of opportunity to know or understand how the event came about. But considerable confusion apparently existed, not so much with respect to the limits of the application of the doctrine as to its procedural effect. 19a Many early cases, while recognizing the doctrine, apparently failed to grasp the significance of the distinction between a presumption and an inference, partly because the evidentiary presumption was under development during that period and partly because the presumption did not have the general judicial force it has today.20 Consequently, the evolution of judicial policy in failing to settle upon the procedural consequences of the res ipsa element prevented any possible crystallization of res ipsa loqui- tur. An examination of some early cases reveals that res ipsa loquitur situations ran the gamut of interpretation. 21 Some courts were apparent- ly confused in the definition of the terms presumption and inference. New York was particularly convinced that a presumption was raised by the doctrine 22 while other eastern courts preferred the inference theory.2 One court employed res ipsa loquitur in a specific negligence case.?Another called proof by purely circumstantial evidence res ipsa loquitur.2 5 Yet another boldly proclaimed that negligence is never presumed but in the same breath declared that res ipsa loquitur is one mode of 19 Nebraska Bridge v.

MAINE LAW REVIEW showing negligence and that the negligence must be controverted or the plaintiffs are entitled to recover. 26 When res ipsa loquitur became the subject of discussion by scholars, the focus of their attention was the problem of procedural effect which the courts had found to be so difficult. Like the courts, they disagreed about whether res ipsa loquitur operated to create a presumption or an inference. The attention of the more recent writers is similarly directed at the procedural consequences, to the detriment of more fundamental problems which the historical development of the doctrine has caused them to neglect. III THE PRESENT CONTROVERSY In recent years four eminent legal writers brought the controversy between inference and presumption into sharp focus. In fact, the two of them favoring inference have gone so far as to propose rejection of the res ipsa loquitur concept, while realizing it is something to which they must submit in some degree because of its widespread popularity. In the course of their controversies these scholars have narrowed the argument and shed considerable analytical light on the concept. While fully appreciating the instructive value of their conflicting theories we feel that the real crux of the matter involves a distinction between res ipsa loquitur and circumstantial evidence rather than a controversy between inference and presumption. The most basic thesis of Prosser2 and Seavey 28 is that cases applying res ipsa loquitur are really not distinguishable from cases generally where a jury is permitted to make findings based on circumstantial evidence. The theory is that permitting the jury to find that the defendant was negligent despite the lack of direct evidence establishing such negligence amounts to nothing more than permitting the jury to infer the existence of fact A from a proof of the existence of fact B. In Seavey's view, "There is nothing peculiar in the situations in which the phrase is used except the paucity of evidence." 29 This suggests that res ipsa loquitur is only a means of classifying the more extreme or dramatic instances where circumstantial evidence is permitted, and that perhaps without the aid of some such slogan the circumstantiality would be deemed fatally tenu369, 64 At. 246 (1905). Res Ipsa Loqttitur, 20 MINN. L. REv. 241 (1936); and Prosser, Res lpsa Loquitur: A Reply to Professor Carpenter, 10 So. CAL. L. REV. 458 (1937). 28 See Seavey, Res lpsa Loquitur: Tabula in Naufragio, 63 H~Av. L. Rnv. 643 (1950). 29 Id., at 645. 26 Wood v. Wilmington City Ry., 21 Del. 27 See Prosser, The ProceduralEffect of RES IPSA ous and speculative. Seavey goes on to attack Ybarra v. Spangard"° as a wrongful application of res ipsa loquitur or any conceivable concept of circumstantial evidence, at least as applied to some of the defendants, because under the facts there was nothing proved from which their fault could be inferred other than on a basis of purely extravagent speculation. It is argued that such an approach would lead logically to the absurd conclusion that the mere access to the facts is sufficient to prove a case against a defendant without any proof of facts whereby fault of the defendant could be inferred. Such a line of reasoning would expose a mere bystander to liability simply because he happened to see what went on, if from the nature of the case the plaintiff himself could not furnish direct evidence of the occurrence. The two defenders of res ipsa loquitur are Professors C. E. Carpenter2 1 and Jaffe. 32 They also agree that much of what passes as res ipsa loquitur is indistinguishable from the rules as to circumstantial evidence and should be absorbed by them. However, they do discern, with no little subtlety and refined perception, an area of independent operation of the doctrine. This may be said to include, roughly speaking, cases where there is a substantial but indeterminate probability that the defendant was negligent and where the defendant has greater access to the facts than does the plaintiff. In such cases one distinguishes res ipsa loquitur from the ordinary case of circumstantial evidence by adding or emphasizing the requirement that the defendant have greater access to the facts, while not insisting that he have complete or exclusive knowledge. This aspect has been traditionally referred to as a requirement of exclusive control of the instrumentality or situation by the defendant, and under the Tentative Draft of the second Restatement is covered by the requirement that the evidence eliminate other responsible causes. 3 A case in which the defendant has no greater means than the plaintiff of explaining the event must stand or fall on the basis of the sufficiency of the circumstantial evidence alone, and the slapping of the Latin tag on it is redundant and superfluous. This would be the case, for example, with the exploding carbonated drink bottle cases, where the defendant can normally offer no real evidence as to the facts of the explosion of the particular bottle in question, and can only show the care exercised in its standard and routine bottling procedures. Scholars who take such a view would be equally critical of Ybarra v. Spangard and limit res ipsa 30 25 Cal.2d 486, 154 P.2d 687 (1944). 31 See Carpenter, Res Ipsa Loquitur: A Rejoinder to Professor Prosser, 10 So. CAL. L. REv. 467 (1937). See Jaffe, Res Ipsa Loquitur Vindicated, I BUFFALO L. REv. 1 (1951). TORTS § 328D(1)(b), comments f, g, h, and i (Tent. Draft No. 5, 1960). 32 33 REsTATEMENT (SEcoND), MAINE LAW REVIEW loquitur to cases where the evidence would permit a reasonable inference of the defendant's faulty complicity. Jaffe makes a presumption an essential element of res ipsa loquitur if it is to be preserved as a phenomenon distinct from circumstantial evidence. In a circumstantial evidence case, involving no presumption, the defendant presents his case, by way of attempted explanation of the event or a showing of exercise of care, or whatever, and then the whole matter is sent to the jury, which may choose to disbelieve the defendant and find for the plaintiff on the strength of his circumstantial case. Where there is a presumption, however, the plaintiff's case is destroyed where the defendant brings in evidence rebutting the presumption, and Jaffe then awards the defendant a directed verdict, and the jury will not be allowed to take the case and disbelieve the rebutting evidence. The only requirement on the defendant is that his evidence be of a respectable and reasonably credible nature, and this is a matter for the judge rather than the jury to determine. This does leave a haunting doubt in one's mind as to how one is to determine the worthy character of the defendant's evidence short of the traditional method of the convincing of a jury, to which Jaffe contends the rebutting defendant should not be subjected. The distinction between circumstantial evidence and res ipsa loquitur is a subtle one at best. In most instances circumstantial evidentiary facts must lead to and establish a proposition which of itself has a relative probative value. The proposition can be supported by an infinite synthesis of testimonial assertions and circumstances.34 Circumstantial evidence is limited by the predictable possibilities and requires that the proponent take an affirmative stand in the proof of his case; but in the res ipsa loquitur case the plaintiff is allowed an infinite number of avenues to reach the jury by virtue of a negative or lacuna in proof; i.e., he shows that the event happened, therefore the defendant must have been negligent, thereby circumventing the normal chain of proof. There are many conceivable factual situations where either res ipsa loquitur or circumstantial evidence could be utilized to obtain the desired result, although sometimes courts have adopted the wrong procedural 35 device. IV DISTINGUISHING RES IPSA LOQUITUR FROM CIRCUMSTANTIAL EVIDENCE With regard to the inference permitted under res ipsa loquitur, we submit that it should be enough that merely a general and unspecified negligence be inferable from the facts put in evidence. This is not, See WIGMORE, EVIDENCE § 25 (3d ed. 1940). 35See Peer v. Ryan, 54 Mich. 224, 19 N.W. 961 (1884); Shaw v. Calgon, Inc., 34 35 N.J. Super. 319, 114 A.2d 278 (1955). RES IPSA strictly speaking, inference of an evidentiary fact, but rather of a conclusion. It is not required that the fact proven give rise to an inference specifically of another fact or other facts upon which a conclusion of negligence could be predicated. Rather may the direct conclusion of negligence as an abstraction be made, without specification of what facts were found, by inference, as the basis for the conclusion of negligence. The language of the Tentative Draft of the second Restatement clearly supports this view. 36 But there is a difference between a direct inference of negligence and an inference of further facts which are to be the actual basis for the conclusion of negligence. Byrne v. Boadle3 7 is clearly a case where the conclusion of negligence was directly made without any intervening inference of specific facts. Why the barrel fell out of the building is not made a subject of speculation. In the absence of additional proof, it is possible to imagine that the event was caused by any number of reasons for which the defendant would be responsible. Perhaps a workman threw the barrel out by way of disposing of the trash; perhaps the defendant's employees were throwing the barrel around in a frolicsome game of catch; perhaps the barrel was being rolled across the floor without heed to the proximity of an open window; perhaps the barrel was inadequately secured on some kind of incline. This speculation could be indefinitely expanded, but quite pointlessly, because the fact of the barrel's having fallen out of the warehouse building is sufficient to permit an inference of the defendant's negligence. It is immaterial that any specific fact constituting such negligence be inferred, provided the inference include an indeterminate number of facts, any one of which could constitute the negligence. This is to be contrasted with the situation where the proven facts can give rise to only one or a limited number of specific facts upon which negligence can be predicated. Such a case would be where the defendant left his car parked on a hillside, no other persons were in the vicinity, and a few minutes later the car rolled down the hill and crashed through the plaintiff's store window at the bottom. It is difficult to see here how more than two specific facts could be inferred from which to append the defendant's negligence. One would be that the defendant had failed to set his brakes, and the other would be that his brakes were defective. This type of situation, where the inference is as to one or a limited and ascertainable number of specific facts, is adequately covered by the usual concepts of circumstantial evidence. In such a case, instructions to the jury could be, "You will find for the plaintiff if you believe either that the defendant failed to set his brakes or that he failed to have his brakes in proper working condition." This does not seem to require any special dispensations from the normal rules of proof that are not already embodied in the principles of circumstantial evidence. 36 § 328D, comment b. 372 H.&C. 722, 159 Eng. Rep. 299 (Ex. 1863). , MAINE LAW REVIEW This suggests, as the distinctive residue for res ipsa loquitur, situations where the inference relates to negligence directly rather than to specific facts. If this limitation is engrafted upon the other limitations regarding the distinctions as to circumstantial evidence and the requirement that the defendant have superior access to facts about the occurrence itself, the classification of res ipsa loquitur becomes clearer. Our analysis is not novel, since it appears to have been the thinking of the plaintiff's counsel in the London Docks Case, when he argued successfully, "The true test is whether the case is more consistent with negligence than care." With regard to Jaffe's theory, it seems that we need not quarrel with his insistence on the presumption, because his theory, too, would necessarily limit res ipsa loquitur to cases where the inference or presumption does not relate to further specific facts, but rather to the abstract conclusion of negligence. Thus, if we apply Jaffe's presumption theory to Byrne v. Boadle, the defendant would have destroyed the plaintiff's case if he had introduced respectable evidence to the effect that a trespasser had entered the warehouse and, ere the defendant or any of his servants were the wiser, had callously tossed the barrel on the plaintiff's head. Similarly, actions against bottlers for damages resulting from exploding bottles would probably not be res ipsa loquitur cases because ordinarily the defendant bottler has no information concerning the actual exploding of the bottle. Rather, the jury would be allowed to infer from the fact of the explosion the further fact that the defendant had used too weak a bottle for the amount of pressure to be anticipated. The defendant could introduce exonerating evidence regarding such matters as the care and prudence used in his usual bottling procedures, but none of this would bear directly upon the happening of the explosion in question. Since the defendant has no superior access to the facts of the occurrence, the case is one of circumstantial evidence rather than res ipsa loquitur. Under the Jaffe theory no presumption applies and the whole matter goes to the jury for its belief or disbelief as to the defendant's using too weak a bottle. But in our view it is really immaterial to the existence of a res ipsa loquitur case, as distinguished from one of circumstantial evidence, whether a presumption or a permissible inference is deemed to result. The distinction between the two cases is based on whether the proven evidentiary facts of the occurrence are going to give rise to a projection toward a conclusion of negligence or toward the proof of further specific facts. The procedural effect to be given the res ipsa loquitur case, as between inference and presumption, is a further and distinct consideration and not essential to the distinguishing of the res ipsa loquitur case. Also, this analysis eliminates the conflict between Jaffe RES IPSA and the second Restatement, which seems inherent in Jaffe's insistence on the presumption. The distinctions we are attempting can be tested against some situations where injury occurred to the plaintiff under circumstances where the plaintiff could not directly prove the specific acts constituting the negligence. Whether these are res ipsa loquitur cases rathe, than circumstantial evidence would depend on whether the infeence would involve one or a few facts indicating negligence or would involve a necessary leap to a conclusion of negligence. Exploding bottle cases are among those illustrative of this distinction, especially those typical ones where the defendant is the bottler and the plaintiff a customer at a retail outlet. 38 Such a defendant would presumably have no agent on hand in charge of the bottle or in a position to witness its explosion; about the only conceivable fact iniputable to the defendant's responsibility is that defendant let tae bottle out of its plant in too weak a condition for the pressure it should reasonably be designed to withstand. 39 But if the defendant were the retail store the case would be one for res ipsa loquitur; for, first, such a defendant would be in a position, as the plaintiff would not, to give evidence as to what disposition had been made of the bottle at the time of and immediately prior to the explosion, and, second, the range of possible facts, imputable to the responsibility of such a defendant, which conceivably could have caused the explosion, are indefinite or limitless: the bottle might have been dropped on the floor, exposed to unreasonable heat or cold, subjected to unreasonable weights on top of it, ex40 posed to harmful or dangerous chemicals, and so on. Two relatively recent cases, whose facts seemingly suggest direct lineage from a hoary ancestor in Byrne v. Boadle (and are almost as picturesque), nevertheless do not carry the same bloodstream, and 41 further illustrate our distinction. One is Larson v. St. Francis Hotel. There the plaintiff was denied recovery for injuries resulting from a chair falling out of the defendant's hotel window, on the theory that a hotel has so many persons as guests whom in the nature of things it cannot control that there were insufficient grounds for allowing the 3 8 The exploding bottle problem is surveyed in Pound, The Problem of the Exploding Bottle, 40 B.U.L. REV. 167 (1960). 39 See Zentz v. Coca Cola Bottling Co., 39 Cal. 2d 436, 247 P. 2d 344 (1952), as typical of these cases. While agreeing with the result the court reached in holding it permissible for the jury to find by inference that the defendant had excessively charged the bottle and was thereby negligent, we must disagree with the court's characterization of this as res ipsa loquitur rather than circumstantial evidence. 40An example of res ipsa loquitur applied against the retailer is Loch v. Confair, 372 Pa. 212, 93 A.2d 451 (1953). 4183 Cal. App. 2d 210, 188 P.2d 513 (1948). MAINE LAW REVIEW jury to believe that it was through fault of the defendant that the chair fell out of the window. Res ipsa loquitur was denied. However, the only possible basis for recovery would be res ipsa loquitur rather than circumstantial evidence, for the possible facts imputable to the defendant's causing the chair to fall out would be innumerable and only tile defendant would have any means of explaining the event. Thus, on tile state of the evidence, the case was correctly determined on the basis of res ipsa loquitur. 42 The other seemingly cognate case is Connolly v. Nicollet Hotel. There the plaintiff, on the sidewalk outside the defendant's hotel, was struck and injured by a mass of muddy substance falling from the hotel. Had this been the sum total of the evidence, presumably the fate of the case would have depended on its congeniality to res ipsa loquitur; and, on the authority of the Larson Case, the plaintiff presumably would have failed. However, it was shown additionally in the case that an exceptionally rowdy Junior Chamber of Commerce convention had been in progress in the hotel, and that the management was painfully aware of this through destruction of hotel property. The court considered that this condition could give rise to a duty on the part of the hotel toward the plaintiff to exercise restraint and control over its boisterous guests, and that the jury might properly infer from the falling of the mass of mud the further fact that the defendant had failed to restrain its guests. The language of the opinion was carefully couched in terms of inferences from circumstantial evidence rather than res ipsa loquitur. This is consistent with our thesis that this was properly a circumstantial evidence case rather than res ipsa loquitur, because the inference to be drawn was the fact of inadequate restraint of guests of the hotel rather than an unspecified inference of negligence without regard to any specific facts constituting the negligence. V CONCLUSION Our conclusion is that the hallmarks of res ipsa loquitur, beyond those specified in the second Restatement draft, are that the defendant have at least markedly superior access to facts explanatory of the accident and that the permissible inference to be drawn from the happening which could result in the defendant's liability be a conclusion of negligence rather than a circumstantial finding of specific facts upon which the defendant's negligence could be predicated. If these criteria are not met in cases otherwise seeming to meet the res ipsa loquitur specifications, the less exceptional doctrines regarding circumstantial evidence really govern. 42 254 Minn. 373, 95 N.W.2d 657 (1959).
