Case Style: Kirkbride v. Terex USA

Case Number: 14-4023

Judge: Timothy Tymkovich

Court: UNITED STATES COURT OF APPEALS TENTH CIRCUIT

Plaintiff's Attorney: Tracy H. Fowler

Defendant's Attorney: Paul M. Simmons

Description:






In 1980 Terex’s predecessor manufactured and sold the portable rock-crushing
plant at issue. As the name suggests, a rock-crushing plant is a large machine that
crushes larger rocks into smaller ones. This particular plant was about the size of a large
semitrailer and consisted of several components: a set of wheels, a chassis, a feeder
system to carry material into the crusher, the crusher itself, a diesel engine to drive the
crusher, and a conveyor to carry crushed material from the crusher.
Because a central issue in this case is whether the rock-crushing plant had a
defective part—a “toggle plate”—that caused Kirkbride’s injury, we describe how the
plant works. The process begins with material being loaded into a long, narrow feeder
(about 20 feet long by 3.5 feet wide) that leads into the opening at the top of the crushing
chamber. To prevent oversize rocks from clogging the chamber’s opening, the crushing
plant when sold had a large metal bar called a crossmember before the opening to the
crusher. Material that passes under the crossmember continues forward until it falls into
the crushing chamber. Reproduced below from the plant’s operation and maintenance (O&M) manual is
a diagram of the crusher: Aplt. App., Vol. 11 at 2389. When material enters the crushing chamber, it is crushed by
two jaws, one stationary (labeled “7” in the diagram) and one movable (8). The top of
the movable jaw, powered by the pitman (1), follows a circular path with a diameter of
1¼ inches, closer to and then farther from the stationary jaw. The cyclical compression
progressively breaks the material, allowing it to slip farther down the “V” between the
jaws until it is small enough to fall through the gap at the chamber’s bottom.
The bottom of the movable jaw is connected to a rectangular metal plate called a
toggle plate (10) and two tension rods (15), which pull the movable jaw toward the toggle
plate and away from the stationary jaw. Besides keeping the bottom of the movable jaw
in place, the toggle plate also functions as a protective device for workers and the jaw
crusher itself. When uncrushable material (such as a large piece of metal) falls between
the jaws, the jaws can jam and store energy as they exert pressure in an effort to crush the
uncrushable material. As the pressure builds, the toggle plate acts as the “weakest link”
and breaks before other, more expensive components (like the pitman) are damaged. Id.,
Vol. 7 at 1621. When it breaks, there is nothing to hold the bottom of the movable jaw in
place, so it swings open and the uncrushable material falls out. The danger to workers is
that if the toggle plate does not break and a worker tries to dislodge the uncrushed
material, the stored energy can cause the material to eject violently from the crushing
chamber when it is released.
Terex’s manuals explain the purpose of the toggle plate and the dangers of stored
energy caused by jaw-crusher jams. The O&M manual contains two statements. The
first is: “The toggle plate is the oscillating link between the bottom of the pitman and the
base toggle seat. It serves as a safety device in the crusher and will break when
uncrushable material is encountered.” Id., Vol. 11 at 2417. The second is: “The
replaceable cast iron toggle plate also serves as a fuse or safety device in the crusher, as it
will break when uncrushable material such as a shovel tooth passes between the jaws.”
Id. at 2391. And the safety manual contains the following warning for those occasions
when material nevertheless gets stuck: “Use extreme caution when removing tramp iron
from the crusher. Stored energy in jaw could cause serious bodily injury.” Id. at 2495.
The written warning is accompanied by an illustration of a worker reaching down into the
crushing chamber and being struck in the face by an ejected foreign object. That is what
happened to Kirkbride.
B. The Accident and Aftermath
After the rock-crushing plant was sold in 1980, it changed hands several times
before being acquired in 1999 by Harper Sand and Gravel, Kirkbride’s employer. At
some point before Kirkbride’s injury in August 2008 the plant’s crossmember was
removed, and its warning placards may have been lost as well. Harper modified the plant
by replacing its original diesel engine with an electric motor, reducing from 16 to 8 the
number of v-belts transferring power from the motor to the flywheels, and replacing the
feeder’s hydrostatic drive with an electric one. Harper requested from Terex a complete
set of manuals for the plant; and in June 2008 (two months before Kirkbride’s injury)
Harper ordered a new Terex toggle plate for the crushing plant and installed it within a
few weeks.
On August 2, 2008, Harper employees were running the crushing plant when they
noticed that a large boulder had become stuck in the crushing chamber, just above the
jaws. They shut down the feeder and the jaw crusher and attempted, unsuccessfully, to
pull out the boulder with a chain pulled by a front-end loader. A supervisor noticed their
efforts and called in Kirkbride, a front-end-loader operator, to help. The workers turned
the crusher back on and attempted to break up the boulder by lowering a 19-inch metal
“ripper tooth” on a chain into the jaws. The tooth broke off the chain and fell into the
crushing chamber, wedging into the gap at the bottom and jamming the jaws. The v-belts
driving the crusher began to smoke and squeal as the jaws futilely attempted to crush the
tooth. The toggle plate did not break. The workers turned off the power and finally
managed to remove the boulder by having Kirkbride pull it out with a chain attached to a
track hoe. But the ripper tooth remained stuck.
Kirkbride brought an acetylene torch, climbed into the crusher, and began cutting
the tooth. With a loud bang the tooth shot out of the jaws, striking Kirkbride’s neck and
jaw as it flew 25 feet into the air.
A few days after Kirkbride’s injury the plant was put back into operation without
changing the toggle plate then or at any time later while the plant remained in Harper’s
control. Harper sold the plant in 2010, and it was inspected by the parties in July 2011.
Critically, although Terex toggle plates for this kind of plant are designed to be just 1⅞
inches to 2 inches thick, the toggle plate found inside the plant was 2 inches thick.
C. Procedural History
Kirkbride sued Terex in Utah state court on theories of negligent manufacturing
and design, negligence in providing inadequate warnings and instructions, strict products
liability for manufacturing and design defects and for failure to warn, and for breach of

8
express and implied warranty. Terex removed the case to the United States District Court
for the District of Utah on the basis of diversity jurisdiction. See 28 U.S.C. §§ 1332,
1441. Before trial, Kirkbride narrowed his claims to negligence, strict products liability
(based on the alleged manufacturing defect in the toggle plate and the company’s
allegedly inadequate warnings and instructions for resolving crusher jams), breach of
express warranty (based on Terex’s statements in its manuals that the toggle plate “will
break” when uncrushable material enters the jaws), and breach of the implied warranty of
merchantability. Aplt. App., Vol. 1 at 111–12 (internal quotation marks omitted). At
trial, Terex unsuccessfully moved for judgment as a matter of law when Kirkbride rested
his case. After the close of evidence, Kirkbride withdrew his express-warranty and
negligence claims. The verdict form requested jury findings on the three remaining
theories of liability. It asked (1) whether Terex failed to adequately warn users of the jaw
crusher’s dangers and whether that was a cause of Kirkbride’s injury; (2) whether Terex
manufactured the toggle plate that was in the crusher on the day of the accident, whether
the toggle plate was defective, and whether the defect was a cause of Kirkbride’s injury;
and (3) whether Terex breached an implied warranty of merchantability that the toggle
plate was fit for its ordinary purpose and whether that was a cause of Kirkbride’s injury.
The jury found Terex liable on all three theories and awarded Kirkbride damages of over
$3.5 million. Terex filed a renewed motion for judgment as a matter of law or for a new
trial, which was denied.

9
II. DISCUSSION
Terex argues that there was insufficient admissible evidence for the jury to find
liability on any of Kirkbride’s three theories, so the trial court erred in denying its motion
for judgment as a matter of law. “Because this is a diversity case, we apply the
substantive tort law of Utah” to Terex’s challenges, Brown v. Sears, Roebuck & Co.,
328 F.3d 1274, 1278 (10th Cir. 2003), but we apply the federal-law standard for
judgment as a matter of law, see Jones v. United Parcel Serv., Inc., 674 F.3d 1187, 1195
(10th Cir. 2012). Under our standard, we review denial of the motion de novo, and Terex
is entitled to judgment as a matter of law only “if the evidence points but one way and is
susceptible to no reasonable inferences supporting the party opposing the motion.”
Deters v. Equifax Credit Info. Servs., Inc., 202 F.3d 1262, 1268 (10th Cir. 2000) (internal
quotation marks omitted). “[W]e will not weigh evidence, judge witness credibility, or
challenge the factual conclusions of the jury,” and will afford Terex the relief it seeks
“only if there is no legally sufficient evidentiary basis” for Kirkbride’s claims. Id.
(internal quotation marks omitted); see Fed. R. Civ. P. 50(a)(1). Because the same
damages are recoverable under each theory, Terex must prevail on all three theories of
liability to obtain reversal of the judgment: “So long as the jury’s verdict was supported
by sufficient evidence under at least one valid theory of liability presented to the jury, we
must affirm.” United States ex. rel. Absher v. Momence Meadows Nursing Ctr., Inc.,
764 F.3d 699, 709 (7th Cir. 2014).

10
A. Failure to Warn
We first review the challenge to the jury’s finding that Terex was liable for failure
to warn adequately of the jaw crusher’s dangers. Under Utah law, “a manufacturer who
sells a product in a defective condition unreasonably dangerous to the user is strictly
liable for any physical harm caused by the defect notwithstanding the fact that the
manufacturer has exercised all possible care in the preparation and sale of his product.”
House v. Armour of Am., Inc. (House I), 886 P.2d 542, 547 (Utah Ct. App. 1994)
(internal quotation marks omitted). One such defect is an “inadequate warning regarding
a product’s use[, which] may render that product unreasonably dangerous.” Id. But
“[b]efore a manufacturer may be held liable for a failure to warn, that failure must be
both the cause-in-fact and the proximate cause of the user’s injury.” Id. at 551.
Kirkbride argues that the warning was inadequate because it was not accompanied
by an instruction on how to remove uncrushable material from the crusher (although he
has not suggested what the instruction should have said). We need not decide the
adequacy of the warning, however, because there was no evidence that a better warning
would have prevented Kirkbride’s injury. The Utah Supreme Court has said, “[I]f the
event which produced the injury would have occurred regardless of the defendant’s
conduct, then the failure to provide a warning is not the proximate cause of the harm and
the plaintiff’s claim must fail.” House v. Armour of Am., Inc. (House II), 929 P.2d 340,
346 (Utah 1996) (internal quotation marks omitted). That is the case here.

11
As mentioned earlier in this opinion, Terex’s safety manual warned workers to
avoid doing exactly what Kirkbride did by exposing his head to metal stuck in the jaws:
Aplt. App., Vol. 11 at 2495. But Kirkbride read neither the crushing plant’s safety
manual nor the (O&M) manual. Indeed, when asked if he had even read the manual for
the front-end loader, he replied, “Why would you read a manual?” Id., Vol. 6 at 1242.
Kirkbride asserts, however, that it was established at trial that Harper’s
maintenance people would refer to the manuals when performing repairs, and the
manuals were supposed to be part of the training for workers assigned to operate the
crushing plant. Therefore, he argues, “[t]he jury reasonably inferred from this evidence
that, had Terex provided adequate instructions and warnings for what to do when [a jam
occurs], the Harper employees working on the crusher would have been trained in those

12
procedures, Mr. Kirkbride would have followed the instructions, and he would not have
been injured.” Aplee. Br. at 57‒58.
This assertion and argument finds no support in the record. There were four
workers on the scene at the time of the accident: Kirk Fetzer, Loren Slaymaker, Barry
Gloster, and Marcos Vallartes. Fetzer and Slaymaker testified at trial, Gloster testified by
deposition, and Vallartes could not be located. There is no evidence that any of them
read the warning that was given. Indeed, the evidence shows that none of those present
had even been trained on clearing a crusher jam by anyone who had read the manuals.
Fetzer said that his only training on how to remove jams came from Vallartes. And
despite Terex’s probing of many witnesses, none could say that Vallartes had ever been
trained on the crushing plant or had read its manuals. Slaymaker testified that his only
training with Harper consisted of an eight-hour classroom course sponsored by the Mine
Safety and Health Administration and that he had received no training on crushers.
Gloster testified that he was never trained on how to fix crusher jams until after the
accident. Fetzer, Slaymaker, and Gloster all denied ever reading or being instructed to
read any portion of the crushing plant’s manuals before the accident. And there is no
evidence that anyone present told Kirkbride that he should be very cautious while
removing uncrushable material from a jam, including by—at the very least—keeping his
head clear (a warning that was in the manual). Cf. Gen. Motors Corp. v. Saenz ex rel.
Saenz, 873 S.W.2d 353, 359 (Tex. 1993) (“If despite the inadequacy of [the
manufacturer’s] instructions, following them would have prevented the accident, then

13
their inadequacy could not have caused the accident.”). It would be pure speculation to
assume that the instruction (of unknown content) now demanded by Kirkbride would
have been heeded.
Kirkbride protests that he proved causation with the help of a “heeding
presumption.” Aplee. Br. at 58. According to this doctrine, adopted in Utah and many
other jurisdictions, “in cases in which it cannot be demonstrated what the plaintiff would
have done had he or she been adequately warned, the plaintiff should be afforded a
rebuttable presumption that he or she would have followed an adequate warning had one
been provided.” House II, 929 P.2d at 347 (internal quotation marks omitted). Under
Utah law this presumption must be rebutted by a preponderance of the evidence. See
Utah R. Evid. 301; Barron v. Labor Comm’n, 274 P.3d 1016, 1020 n.3 (Utah Ct. App.
2012).
There may be some question about the scope of the presumption, but at trial
Kirkbride relied on it in the following form: “You can presume that if Terex had
provided an adequate warning, Mr. Kirkbride would have read and followed it unless the
evidence shows that Mr. Kirkbride would not have read or followed such a warning.”
Aplt. App., Vol. 1 at 159 (Jury Instruction No. 22). Terex conclusively rebutted the
presumption. Not only had Kirkbride not read the warning that was in the manual but he
expressed a negative view of manuals. See id., Vol. 6 at 1242 (“Why would you read a
manual?”).

14
Thus, the element of causation necessary for Kirkbride’s claim rests entirely on
speculation. But “[t]o support a jury verdict, evidence must be based on more than mere
speculation, conjecture, or surmise.” Rice v. United States, 166 F.3d 1088, 1092 (10th
Cir. 1999). We must vacate the jury’s verdict on the failure-to-warn claim.
B. Manufacturing Defect
Next we address Kirkbride’s manufacturing-defect claim. To succeed on such a
claim, a plaintiff must prove that (1) the manufacturing defect made the product
unreasonably dangerous, (2) the defect was present at the time of the product’s sale, and
(3) the defect caused the plaintiff’s injury. See Schaerrer v. Stewart’s Plaza Pharmacy,
Inc., 79 P.3d 922, 928 (Utah 2003).
Kirkbride’s theory centered on the crushing plant’s toggle plate. As described
earlier, the toggle plate is a relatively thin metal plate connected to the bottom of the
movable crushing jaw. When the jaw encounters uncrushable material, it is the toggle
plate’s job to break, both for safety and to prevent a pressure buildup that causes
something more valuable to break instead. Doubtless a thicker plate is harder to break.
And the toggle plate found in the plant in July 2011 (about three years after the accident)
was 3/16ths of an inch thicker than Terex’s design specification. Had the toggle plate
been manufactured properly, Kirkbride said in his opening statement to the jury, it would
have broken as designed, the jaw would have swung open, and the ripper tooth would
have fallen safely through, averting his injury.

15
Terex argues that Kirkbride’s theory suffers from three fatal flaws: (1) the only
evidence establishing that the defective toggle plate was manufactured by Terex came
from inadmissible and insufficient expert testimony; (2) there was no evidence that the
thickness of the plate rendered the crusher unreasonably dangerous; and (3) there was no
evidence that the defect—the extra thickness—was the cause of the plate’s failure to
break. Because Terex prevails on (3), we need not address (1) or (2).
The alleged manufacturing defect is that the toggle plate was thicker than the
design specifications. Kirkbride alleges that this defect caused the plate not to break. An
essential element of his proof of causation therefore must be that a properly manufactured
plate would have broken in the circumstances of the August 2008 accident. Consider an
example. Suppose that a 2-inch plate breaks if subjected to 1000 pounds of force and a
2 -inch plate breaks if subjected to 1200 pounds of force, but the force on the plate the
day of the accident was only 900 pounds. Although a defective plate is harder to break,
the force would be insufficient to break either one, so the defect would not be a cause of
the jam. It is not obvious that a properly manufactured plate would always prevent a jam.
After all, if the plate broke too easily, operations could be interrupted too often. (No
Harper employee testified that he had ever seen a toggle plate break when the Terex
crusher (or any other crusher) had jammed, even though all were familiar with jams and
several had worked with crushers for years.) And the safety-manual warning about
jammed tramp iron implies that the plate would not always break.

16
We agree with Terex that there was inadequate (nonexistent) proof that a
nondefective plate would have broken. Kirkbride’s expert witness, Benjamin Railsback,
was the only witness who discussed causation. Railsback, however, never analyzed
whether a properly manufactured plate would have broken during the circumstances of
Kirkbride’s accident. Rather, he simply testified, without calculations, testing, or other
application of scientific methodology, that a thicker plate is—obviously—more difficult
to break than a thinner one. When confronted on cross-examination with the fact that he
had not run any tests to determine whether a defective plate would break, he replied,
“That’s true, I don’t know whether it would break or not. I don’t need to do any testing
as a mechanical engineer to know that something that’s too thick is more difficult to
break.” Aplt. App., Vol. 5 at 1073. But when next asked whether he had tested if a
nondefective, two-inch plate would have broken, he replied, “No, sir.” Id.
We can find no statement in Railsback’s testimony regarding when a properly
manufactured plate would break. This was no mere oversight. It is clear from the record
that he had no opinion on the matter. Railsback’s only statement in which he compared a
defective plate to a nondefective plate came on direct examination, when he opined that
even a properly manufactured plate may not have broken (depending on the design):
[Kirkbride’s attorney]: Why didn’t the toggle plate break? [Terex’s attorney]: Objection, Your Honor, foundation. THE COURT: Well in his—in your opinion. Go ahead. [Railsback]: In my opinion, the two primary reasons why the toggle plate didn’t break, the first reason is that it was too thick. This toggle plate was manufactured with a thickness of two and three-sixteenths of an inch, not the required dimension of two inches that is in the design drawings. The

17
second reason might be that the toggle plate could have been over engineered or too thick to begin with. That dimension of two inches may be too thick even for normal operation, proper operation of this machine. THE COURT: Yes. [Terex’s attorney]: Move to strike. It is speculative. THE COURT: Yeah, sustained. Id. at 1015‒16 (emphasis added). As indicated, that testimony was stricken by the
district court. (The parties disagree on whether the district court struck the entirety of
Railsback’s answer, or just the second part. But that makes no difference because
Kirkbride had the burden of proving causation and that required—at a minimum—ruling
out the possibility that a nondefective plate would have remained intact, which he did not
do.) What is important, however, is that the emphasized testimony removes any
ambiguity about the absence of causation testimony—it is undisputable that Railsback
had no opinion (and certainly, in the absence of testing or calculations, had no basis for an opinion) about whether a properly manufactured plate would have broken.1
Without expert testimony that a nondefective plate would have broken, the jury
could only speculate that the manufacturing defect was the cause of the plate’s failure to
break. This it was not permitted to do. See Truck Ins. Exch. v. MagneTek, Inc., 360 F.3d
1206, 1215–16 (10th Cir. 2004) (jury finding of causation cannot be based on
speculation); Burns v. Cannondale Bicycle Co., 876 P.2d 415, 418 (Utah Ct. App. 1994) 1 We need not consider Terex’s argument that Railsback was required to conduct testing on the breaking point of toggle plates for his theory to be reliable. It is not the lack of testing that concerns us, but Railsback’s failure to rule out (whether by testing or other means) that a nondefective plate would have also remained intact despite the jam.

18
(a plaintiff must show that his injuries “proximately resulted from the product’s failure of
performance causally related to its defective condition” (emphasis added) (internal
quotation marks omitted)).
Our decision in Bitler v. A.O. Smith Corp., 400 F.3d 1227 (10th Cir. 2004), cited
by Kirkbride, is not to the contrary. The issue in Bitler was the admissibility of expert
testimony, not the sufficiency of the evidence of causation. Here, we have assumed that
Railsback’s unstricken testimony was properly admitted.
C. Implied Warranty
Finally, Kirkbride contends that his judgment can be affirmed on his theory of
implied warranty. Kirkbride brought a tort claim asserting that he was injured because
Terex breached the implied warranty of merchantability when it sold the toggle plate.
But the tort claim for breach of implied warranty has largely been subsumed into the
doctrine of strict products liability. Terex contends that such is the law in Utah, so that
once Kirkbride’s products-liability claims fail—the claim for design defect was
abandoned before trial and we have found that there is insufficient evidence to support
the claims for inadequate warnings and manufacturing defect—there is no need to
address the implied-warranty claim. We agree.
We rely primarily on the Utah Supreme Court’s opinion in Ernest W. Hahn, Inc. v.
Armco Steel Co., 601 P.2d 152 (Utah 1979). In that case the plaintiff had brought claims
for both strict products liability and breach of implied warranty. See id. at 155. The
court summarized the history of the doctrine of strict products liability, noting how

19
liability for negligence had been extended by the use of warranty doctrine but that
limitations in that doctrine led to the birth of the doctrine of strict products liability. See
id. at 156–57. It then adopted the strict-products-liability doctrine as set forth in the
Restatement (Second) of Torts § 402A. Id. at 158. The court devoted little attention to
the plaintiff’s implied-warranty claim. It found it necessary to say only that “[t]he
elements of both actions [implied warranty and strict products liability] are essentially the
same,” so that the same defenses are available to both. Id. at 159 (footnote omitted).
There may be some ambiguity in the language “essentially the same,” leaving
room for the possibility of differences in the elements of the two tort causes of action.
But the historical summary in Hahn would suggest that if there were any differences, it
would be that a warranty claim would be more limited than a strict-products-liability
claim. And later Utah appellate opinions have read Hahn as support for the proposition
that once a claim for strict products liability has been rejected, nothing is added by
considering an implied-warranty claim. In Burns, 876 P.2d at 416, the Utah Court of
Appeals addressed a personal-injury claim alleging defective bicycle brakes. The court
affirmed a summary judgment in favor of the defendant. See id. Citing Hahn, the court
wrote, “Insofar as Burns’s claim for breach of the implied warranty of merchantability is
concerned, no separate analysis is required since it is essentially the same as a products
liability claim.” Id. at 418 n.2. Five years later, the Utah Supreme Court adopted the
same approach in affirming a summary judgment in Straub v. Fisher & Paykel Health
Care, 990 P.2d 384 (Utah 1999). It said: “Straub provides no analysis for her breach of

20
implied warranty claim. We can only assume that she is not appealing this issue. In any
event, the elements of strict liability and breach of warranty ‘are essentially the same.’”
Id. at 389 n.1 (quoting Hahn, 601 P.2d at 159); see also Davidson Lumber Sales, Inc. v.
Bonneville Inv., Inc. 794 P.2d 11, 14 (Utah 1990) (“The term ‘warranty’ has also been
used, however, in tort law to have a meaning that is synonymous with strict liability.”).
Kirkbride cites Utah Local Government Trust (ULGT) v. Wheeler Machinery Co.,
199 P.3d 949, 955 (Utah 2008), for the proposition that the Utah Supreme Court has
“cautioned against merging the two claims [strict products liability and breach of the
implied warranty of merchantability].” Aplee. Br. at 60. That is not how we read the
opinion. What the court did not want merged were contract and tort causes of action,
even if both might be labeled as breaches of warranty. The court said that those who
wish to merge the two “ignore the important conceptual differences between contract and
tort that justify resisting their merger.” ULGT, 199 P.3d at 955.
We conclude that for purposes of a tort claim for breach of the implied warranty of
merchantability, Utah law provides that the warranty is breached only if the plaintiff
establishes the elements of a strict-products-liability claim for defective manufacture,
defective design, or failure to warn. See Grundberg v. Upjohn Co., 813 P.2d 89, 92
(Utah 1991) (“There are three types of product defects: manufacturing flaws, design
defects, and inadequate warnings regarding use.”). This view has authoritative support
outside of Utah. The Restatement (Third) of Torts: Products Liability § 2 comment n
(1998) explains:

21
This Restatement contemplates that a well-coordinated body of law governing liability for harm to persons or property arising out of the sale of defective products requires a consistent definition of defect, and that the definition properly should come from tort law, whether the claim carries a tort label or one of implied warranty of merchantability.
Accord Evans v. Lorillard Tobacco Co., 990 N.E.2d 997, 1010 (Mass. 2013) (claim for
breach of implied warranty of merchantability requires proof of elements of product
defect claim); Wright v. Brooke Grp. Ltd., 652 N.W.2d 159, 181–82 (Iowa 2002);
Freeman v. Hoffman-La Roche, Inc., 618 N.W.2d 827, 843–44 (Neb. 2000); Hyundai
Motor Co. v. Rodriguez ex rel. Rodriguez, 995 S.W.2d 661, 665–67 & n.20 (Tex. 1999);
see also Gumbs v. Int’l Harvester, Inc., 718 F.2d 88, 94–95 (3d Cir. 1983) (collecting
cases for the proposition that implied-warranty and strict-products-liability claims “are
essentially the same,” id. at 94); Dan B. Dobbs et al., Dobbs’ Law of Torts § 448 (2d ed.
2015) (“As some authorities have observed, the standards for determining
merchantability under warranty law and the standard for determining whether a product is
defective in the law of strict tort liability are largely interchangeable.”).
Because Kirkbride’s implied-warranty claim gives him no additional ground for
affirming the judgment below, we also reverse on that claim.

Outcome: We REVERSE the district court’s judgment and REMAND for further
proceedings in accordance with this opinion.

Plaintiff's Experts:

Defendant's Experts:

Comments: Plaintiff Larry Kirkbride was injured while attempting to dislodge a foreign object from a portable rock-crushing plant manufactured by the predecessor of Defendant Terex USA, LLC. Kirkbride brought a products-liability action against Terex, and a jury found the company liable for failure to adequately warn of the plant’s dangers, for defectively manufacturing a critical part inside the crushing plant that led to Kirkbride’s injury, and for breaching an implied warranty of merchantability. Terex argues that Kirkbride failed to present sufficient admissible evidence to establish his three claims and that the jury was wrongly instructed on the implied-warranty claim. Exercising jurisdiction under 28 U.S.C. § 1291, we reverse and remand. Because there was insufficient evidence to hold Terex liable on any of the theories of recovery that went to the jury, Terex is entitled to judgment as a matter of law. Consequently, we need not consider other arguments presented by Terex.
