Bryan ROBERTSON, Plaintiff-Appellee, v. NORTON COMPANY; Williams Equipment & Supply Company, Defendants-Appellants, Continental Insurance Company, Intervenor Plaintiff-Appellee.
Nos. 97-2502, 97-2611
United States Court of Appeals, Eighth Circuit
Submitted Jan. 12, 1998. Decided June 1, 1998.
144 F.3d 590
Scott Allen Emerson, Jonesboro, AR, argued, for Appellee.
Before LOKEN and MURPHY, Circuit Judges, and ALSOP,* District Judge.
LOKEN, Circuit Judge.
On August 12, 1992, Bryan Robertson was using a Black & Decker heavy-duty power sander/grinder on a concrete bridge in Mountain View, Arkansas, working for a construction company owned by his father. Robertson released the grinder‘s trigger and lifted it from the bridge surface. The ceramic-comрosite grinding wheel exploded, and splinters severely injured Robertson‘s leg. After collecting workers’ compensation benefits, Robertson sued the grinding wheel manufacturer, Norton Company, and its distributor, Williams Equipment and Supply Company, for breach of warranty and strict liability in tort. The compensation insurer intervened to assert its right to recover benefits paid.
Following trial, the jury found that the accident was proximately caused by defendants’ conduct in manufacturing and selling the grinding wheel in a defective and unreasonably dangerous condition, and by Robertson‘s own negligenсe. The jury found that Robertson suffered damages of $129,482.55 and apportioned fault under the Arkansas comparative fault statute at 13% for Robertson and 87% for defendants. Norton and Williams appeal the judgment entered on this verdict. The issues are (1) whether the district court erred in admitting exрert testimony that defendants’ product warnings were inadequate; (2) whether Robertson presented sufficient evidence that Norton manufactured and Williams distributed the grinding wheel that exploded; and (3) whether the court committed plain error by failing to instruct the jury to assign comparative fаult to Robertson‘s employer. Agreeing with defendants’ first contention, we reverse and remand for a new trial.
I. Expert Testimony About Product Warnings.
At the time of the accident, Robertson had worked on bridges for over five years and was familiar with the Black & Decker grinder. Norton grinding wheels were purchased separatеly from the grinder and bore a warning label stating: “Warning. Improper use may cause grinding wheel breakage and serious injury. Comply with ANSI B7.1, OSHA, and safety guide furnished with package.” The “safety guide” was a separate pamphlet
A principal witness at trial was Robertson‘s ceramics expert, Dr. Ross Firestone. Much of Dr. Firestone‘s testimony concerned whether the grinding wheеl exploded because of an unreasonably dangerous manufacturing defect. At issue here is his further testimony that Norton‘s product warnings were “completely inadequate” because the warning label did not explain “improper use,” because a copy of the safety guide was not enclosed with each wheel in “blister pack” packaging, and because the warning label‘s cross reference to a 120-page ANSI publication was ineffective. The district court overruled defendants’ attempts to exclude this testimony by a motion in limine and by a сontinuing objection at trial. We review the district court‘s decision to admit expert testimony for abuse of discretion. See General Elec. Co. v. Joiner, 522 U.S. 136, 118 S.Ct. 512, 519, 139 L.Ed.2d 508 (1997).
Our prior opinions have noted problems with expert testimony regarding the adequacy of product warnings:
In the first place the questions called for opinions of the witnesses on one of the ultimate questions in the case; they invaded the province of the jury on a question which the jury was entirely capable of answering without the benefit of their expert opinion, were we to assume that these witnesses had qualified as experts оn the adequacy of labeling.
* * * * * *
Further ... these two witnesses were [not] qualified to express an opinion as to the adequacy of warnings and directions.... Whether or not a given warning is adequate depends upon the language used and the impression that it is calculated to make upon the mind of an average user of the product. Questions of display, syntax, and emphasis are involved in evaluating a warning, or set of directions, and upon those matters plant pathologists and entomologists are not necessarily qualified to speak.
Walton v. Sherwin-Williams Co., 191 F.2d 277, 285-86 (8th Cir.1951); accord Strong v. E.I. DuPont de Nemours Co., 667 F.2d 682, 686 (8th Cir.1981). All of these problеms are present in this case. First, while Dr. Firestone was undoubtedly qualified to testify about a manufacturing defect in an exploding ceramic grinding wheel, that did not qualify him as an expert on grinding wheel warnings. He had never designed a warning for a ceramic product.1 His knowledge of ceramics would not provide the expertise on “questions of display, syntax, and emphasis” that the jury would expect from a bona fide warnings expert.
Second, Dr. Firestone‘s opinion was not supported by the kind of scientific theory, practical knowledge and experience, or empirical research and testing that permit assessment “of whether the reasoning or methodology underlying the testimony is scientifically valid and of whether that reasoning or methodology properly can be applied to the facts in issue.” Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 592-93, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993), quoted in Gier v. Educational Serv. Unit No. 16, 66 F.3d 940, 943 (8th Cir.1995). For example, Dr. Firestone criticized Nоrton‘s warning label for not explaining “improper use.” But grinding wheels are used in grinders. Firestone did not consider whether Norton could feasibly provide a description of “improper use” that would accurately and effectively encompass all the ma-
ta, sitting by designation.

Third, Dr. Firеstone‘s opinion squarely addressed an ultimate issue of fact. Although that is permissible, see
Finally, Dr. Firestone‘s improper opinion testimony was unfairly prejudicial. The warning issue was relevant to Robertson‘s strict liability and breach of warranty claims. See Hill v. Searle Laboratories, 884 F.2d 1064, 1066-67 (8th Cir.1989) (under Arkansas law, inadequate warning is a basis of strict liability and breach of warranty liability). The court instructed the jury that “[a] product may be defective if it does not have a reasonably adequate warning,” and that to be merchantable a product must “be adequately ... labeled.” These instructions tracked Dr. Firestone‘s opinion that Norton‘s warnings were “completely inadequate.” Robertson‘s inadequate warning claim was emphasized in opening and closing arguments.
Robertson argues that Norton аnd Williams failed to preserve this issue because the verdict form does not reveal whether the jury found a manufacturing defect, an inadequate warning, or both. We disagree. When evidence relevant to one of two theories subsumed in a verdict is erroneously admitted, the verdict is sеt aside unless we are “convinced that the jury proceeded only on the sound ground.” Mueller v. Hubbard Milling Co., 573 F.2d 1029, 1039 (8th Cir.), cert. denied, 439 U.S. 865, 99 S.Ct. 189, 58 L.Ed.2d 174 (1978). We are not convinced the jury based its verdict solely on the hotly contested manufacturing defect claim. Accordingly, we conclude that the district court abused its discretion in admitting this opinion tеstimony. Defendants are entitled to a new trial.
II. Sufficiency of the Evidence.
The grinding wheel exploded into fragments, making identification of its manufacturer a key issue at trial. On the one hand, Robertson testified the wheel had a Norton label. His father testified he only bought Norton wheels from Williams, and there was evidencе Williams only sold Norton wheels. On the other hand, laboratory analysis of a wheel fragment showed it was manufactured with barium sulphate filler, and Norton presented evidence it stopped using that filler compound many years before the accident. On appeal, defendants аrgue they are entitled to judgment as a matter of law because Robertson presented insufficient evidence that Norton manufactured and Williams distributed the defective wheel. Reviewing the conflicting trial evidence on this issue in the light most favorable to the jury‘s verdict, as we must, we agrеe with the district court that the evidence was sufficient to permit the jury to find that Norton manufactured and Williams distributed a grinding wheel that exploded due to a manufacturing defect.
III. Comparative Fault of Robertson‘s Employer.
Norton and Williams contended at trial that the negligence of Robertson‘s employer was an intervening sole proximate cause of his damages. The district court instructed the jury on intervening cause. However, the court refused defendants’ request to include Robertson‘s employer in its comparative fault interrogatory to the jury. On appeal, Norton and Williams argue the court erred in refusing to instruct the jury to apportion fault to Robertson‘s employer as a so-called “phantom” party, an instruction we encouraged in dicta in Chaney v. Falling Creek Metal Products, Inc., 906 F.2d 1304, 1308 n. 7 (8th Cir.1990).
The second question concerns the suggestion in Chaney‘s footnote 7 that an allegedly negligent employer should be included as a phantom party in the Arkansas comparative fault instruction “to clarify the legal effect of [the employer‘s] conduct.” The district court concluded this footnote was implicitly overruled by Hiatt v. Mazda Motor Corp., 75 F.3d 1252, 1258 (8th Cir.1996). However, Hiatt did not involve a workers’ compensation situation, so it does not squarely answer the question presented by this case. The relevance of an employer‘s negligence to an employee‘s tort claim against a third party is a contentious segment of workers’ compensation law, with the varying answers often turning on differences in the workers’ compensation statutes enacted by the several States.2
Under the Arkansas statutory workers’ compensation regime, employees injured on the job give up tort remedies against their employers in exchange for guaranteed benefits without regard to fault. See
We conclude the district court did not abuse its discretion in refusing to include Robertson‘s employer as a phantom pаrty in the comparative fault instruction. The comparative fault statute provides that “liability shall be determined by comparing the fault chargeable to a claiming party with the fault chargeable to the party or parties from whom the claiming party seeks to recovеr damages.”
Moreover, even if Robertson‘s prior claim for workers’ compensation benefits were cоnsidered a claim for damages for purposes of
The judgment of the district court is reversed and the case is remanded for further proceedings not inconsistent with this opinion.
