Ordinarily we count on gravity to keep heavy items in place; and so when flour barrels, armchairs, and truck wheels become airborne we assume first that something has gone wrong. Such events, lawyers say, speak for themselves, or in Latin, “res ipsa loquitur,” and the blame for any resulting injury can be imputed to the person who had control of the item before it became a dangerous projectile. Christine Maroules asks the court to adopt this view to delegate to the owner of Jumbo, Inc. trucking company and Jumbo’s driver, James E. Windsor (together, “Jumbo”), blame for injuries she sustained when a wheel broke free from the truck upon which it was mounted, flew through the air, and crashed through the front passenger side of her car. Because she has failed to demonstrate the elements necessary for res ipsa loquitur to apply, however, we affirm the decision of the district court granting summary judgment to Jumbo.
I.
At the time of the accident on January 4, 2000, Windsor was operating the semi-tractor-trailer in question for his employer, Jumbo Inc., driving westbound through Indiana on Interstate Route 80. Windsor did not realize that the two-wheel unit (tandems), consisting of two tires and two rims attached by studs to a wheel assembly, had detached from his truck until he was stopped by an Indiana State Trooper at the border between Illinois and Indiana. At that point he inspected his truck and determined that five or six of the ten studs upon which the wheel unit was mounted were broken and sheared off, although the thread of the portions of the studs that had remained on the trailer did not appear to be worn. The nuts attaching the wheel unit were also missing, and the four or five studs that remained were broken or sheered off. According to Windsor’s affidavit, he had inspected the nuts just a few hours prior to the accident, as part of his routine walk-around inspection which he conducted at the beginning and end of each day and every time he started the vehicle. As part of his inspection he checked the physical condition of the tires, rims, lugs, studs, nuts, and tires’ air pressure. He testified that upon his inspection, the studs and nuts were not loose in any way. Philip Simonsen, the president of Jumbo Inc., testified that the trailer, which he purchased as a used vehicle in 1999, had received a full annual inspection *642 in compliance with U.S. Department of Transportation regulations just five weeks before the accident. Simonsen also testified that Jumbo hires a third-party company to inspect, maintain, and repair its trailers and all of their parts, including the wheel studs, which it had done on numerous occasions prior to the accident. Mr. Windsor testified that the bolts in question can last for several years and “can go until you have a problem,” that is until they turn brown or one breaks off, at which point all studs should be replaced as they tend to reach their breaking points at around the same time. (R. at 40, Ex. 2, p. 78). Maroules contends that ordinary care required the defendants to “take notice of the tendency of parts of machinery to decay from age, or wear out by use, and the law requires them to make reasonable inspection of the various parts of machinery from time to time for the purpose of discovering any defective parts, to the end such parts may be replaced or repaired.” (Maroules brief at 22). In short, Maroules contends that Jumbo should have replaced the wheel studs periodically and prophy-lactically instead of waiting for them to break or show other indicia of failure.
II.
In response to Jumbo’s summary judgment claim, Maroules asked the district court to apply the doctrine of res ipsa loquitur.
1
Res ipsa loquitur is a shortcut to a negligence claim. Although negligence may not be inferred from the mere fact that an injury occurred, it may be inferred from the circumstances surrounding the injury.
K-Mart v. Gipson,
Whether the doctrine of res ipsa loquitur applies in any given negligence case is a mixed question of law and fact.
Syfu v. Quinn,
The defendants begin by denying that they had exclusive control. To support this proposition, they contend that they had no role in manufacturing the trailer or its wheel studs; they had no control over the inspection and maintenance of the trailer or its wheel studs prior to the time that Jumbo purchased the trailer in 1999; and that Jumbo does not maintain, service, or repair its trailers and their parts, but instead relinquishes control every time it sends its trailers to an outside third party maintenance company to do this work.
Jumbo’s argument is appealing on the surface when one contemplates any number of alternative theories for the accident: the stud manufacturer could have negligently or knowingly manufactured defective studs, the maintenance business could have used a faulty power tool to tighten the bolts, or a vandal could have sabotaged the truck wheels. Recall, however, that the doctrine of res ipsa loquitur does not hand victory to the plaintiff; it merely creates an inference of negligence that the trier of fact, upon hearing all of the evidence, may or may not choose to accept.
See Rector,
Maroules however, must also demonstrate that the accident is of the type that does not ordinarily happen if those who have the management and control exercise proper care. Finding that Maroules had failed this second res ipsa loquitur requirement, the district court concluded that, “[u]nlike the numerous cases cited by the plaintiff, there is no evidence in this case that the defendants’ conduct fell below the standard of care that the law imposes on the drivers or owners of tractor-trailers.” (R. at 46, p. 13). Maroules objects to the district court’s statement that “the plaintiff has not come forth with any circumstantial evidence from which a reasonable jury could find that the defendants failed to exercise reasonable care.” (R. at 46, p. 12). It is unclear to which requirement Maroules objects. It is true that the doctrine of res ipsa loquitur does not require a plaintiff to submit evidence of causation.
Gipson,
Although res ipsa loquitur is a doctrine of common sense, expert testimony is required when the issue of care is beyond the realm of the layperson, that is, where a fact-finder cannot determine whether a defendant’s conduct fell below the applicable standard of care without technical input from an expert witness.
Syfu,
[i]n the usual [res ipsa] case the basis of past experience from which the conclusion may be drawn that such events *645 usually do not occur -without negligence, is one common to the whole community, upon which the jury are simply permitted to rely. Even where such a basis of common knowledge is lacking, however, expert testimony may provide a sufficient foundation.
Shull,
On a final note, much ado has been made in this case about the intersection of Indiana’s res ipsa loquitur law and the federal procedural rules for summary judgment. At oral argument, Maroules’ attorney stated that he did not think it appropriate for federal summary judgment procedure to upset Indiana state law concerning res ipsa loquitur. Although state law provides the substantive law in a diversity action, summary judgment procedure is governed by federal law.
Jean v. Dugan,
In any event, we do not think this ease presents a conflict between federal and state law. As Maroules argues, “[o]nce the plaintiff presents evidence to bring herself within the operation of res ipsa loquitur, the inference of negligence is to be weighed by a jury and summary judgment is not proper.” (Maroules Reply Br. at 8). As explained above, however, Mar-oules, has not presented sufficient evidence to bring herself within the operation of the res ipsa loquitur doctrine. Consequently, summary judgment must be granted for Jumbo, and the judgment of the district court is Affirmed.
Notes
. In the district court Maroules also made a straight forward negligence claim. Maroules raises only the res ipsa loquitur arguments on appeal.
