Maria Navarro, the plaintiff in a diversity personal-injury suit which the parties agree is governed by the law of Illinois, was a passenger in a 1982 Subaru that had been manufactured in Japan in 1981 by Fuji Heavy Industries, the defendant. The driver lost control of the car when its rear suspension gave way suddenly and unexpectedly as a rеsult of having rusted through. Navarro
As we said, this suit is based on negligence rather than on strict products liability. But there is little or no practical difference in a ease of defective design, at least so far as the standard of liability is concerned (we have just seen that there is a big difference with respect to the deadline for bringing suit): you must prove that the design was defective in either kind of case, and whether the design was defective is determined by use of the same Hand-formula or cost-benefit approach that is used to determine negligence in a tort case not involving a product. E.g.,
Rosen v. Ciba-Geigy Corp.,
So there is one test, and it is objective,
Flaminio v. Honda Motor Co., supra,
To show that it was defective — that is, that due care required Fuji to design the rear suspension in such a way that it either would not rust even if driven for many years in Chicago or, more plausibly, that'if it did rust the rust would show so that the suspension could be replaced before it gave way — the plaintiff presented the affidavit of a qualified engineer, the recall notice, a corrosion report by a trade association, and an affidavit by another expert that the judge properly ruled inadmissible because unverified and that in any event added nothing material to the first expert’s affidavit. The affidavit of the first expert was the centerpiece of Navarro’s case and the judge found that it was inadmissible under
Daubert v. Merrell Dow Pharmaceuticals, Inc.,
It is noteworthy that the affidavit and the plaintiffs other evidentiary materials were not presented in response to affidavits or other evidence in support of the defendant’s motion for summary judgment. The defendant did not present
any
evidence in support of its motion. It was not required to.
Celotex Corp. v. Catrett,
The district judge was only half right in finding that the expert’s affidavit flunked the
Daubert
test. The expert is an experienced consultant in the relevant fields of failure analysis, mechanical safety, and accident reconstruction; he inspected the ruined еar; and he explained lucidly how the accident had come about — through the insidious corrosion of the rear suspension. So far, so good; there was no basis for excluding this part of the affidavit.
Wheeler v. John Deere Co.,
A more fundamental point is that knowledge of a hazard does not equate to negligence for failing to take a particular precaution against it. Negligence depends on the magnitude and likelihood of the hazard and on the cost of preventing the hazard or reducing its likelihood. E.g.,
Yager v. Illinois Bell Tel. Co.,
The affidavit goes on to state that “prior to 1981, Fuji Heavy Industries knew of the corrosive effects of road salt on the suspension arms of a vehicle”' — but this amounts to nothing more than the truism that a manufacturer of a steel product is charged with elementary knowledge that salt is corrosive. With little more ado the expert concluded that “the design and manufacture of the rear suspension arm in 1981 was negligent and unreasonable.” The affidavit contains no support for this conclusion, and a conclusion without any support is not one based on expert knowledge and entitled to the dignity of evidence.
Daubert v. Merrell Dow Pharmaceuticals, Inc., supra,
509 U.S at 590,
The plaintiff argues that the gaps in the expert’s affidavit would have been filled if only the defendant, before moving for summary judgment, had deposed the expert.
The recall notice adds nothing to the affidavit. It merely shows that in 1990 (for there is no indication that Fuji discovered the problem earlier and sat on it) Fuji discovered the problem of the undetectable rusting. The only other admissible document on which the plaintiff relied in opposing summary judgment is an undated report of the American Iron and Steel Institute on corrosiоn. (Internal evidence suggests that the report was written in the early years of this decade.) The report points out that because of the high cost of electricity in Japan, Japanese auto manufacturers use lighter alloys to rustproof their cars than American manufacturers do but that in view of thе corrosive conditions on many American roads the Japanese manufacturers are moving toward heavier alloys. This is some evidence that in the early 1980s Japanese cars were not as resistant to rust as American cars were, but it is not, without more— and there is no more — evidence that the diffеrence created an incremental hazard great enough to malee the Japanese cars defective.
When the inadmissible, because nakedly conclusional, portions of the expert’s affidavit are stricken, there just is no evidence, though there may be a common-sense suspicion, that the 1982 Subaru’s rear suspension was defective. The district judge was therefore right to grant summary judgment for Fuji. The plaintiff, however, moved for reconsideration under Fed.R.Civ.P. 59(e) and attached a new, amended affidavit of its expert, plus some answers to interrogatories summarizing additional expert testimony, interrogatories that the plaintiff had made a part of the record before the suit had been removed to federal court but had failed to bring to the district judge’s attention — wisely so. For the most arresting answer is an acknowledgment that not until 1985, four years after the manufacture of the fatal vehicle, had Chicago been classified as having severely corrosive road conditions. That was in the AISI report that we mentioned; there is no indication that anyone else does these classifications.
The amended report comes a little closer to adequacy, mainly by citing engineering literature from the 1970s that, according to the affidavit, shows that the corrosion problem in Chicago was well known then and that there were accepted methods of avoiding the hazard that caused the 1982 Subaru to fall apart when it did. The literature is not appended to the affidavit or explained in it; it is merely cited; but we won’t quibble, аnd will assume for the sake of argument that had it been placed in evidence before the judge ruled on the defendant’s motion for summary judgment he would have had to deny the motion. The insuperable difficulty for the plaintiff is that a motion to alter the judgment may not be based on evidence that was available whеn the district judge took the motion for summary judgment under advisement but that was not presented then.
Retired Chicago Police Ass’n v. City of Chicago,
AFFIRMED.
