MEMORANDUM OPINION AND ORDER
When tragedy strikes, people naturally cast about for a cause. They might attribute what happened to fate or karma; find someone else to blame; or ultimately realize that responsibility lies only with themselves. When a lawn mower accident permanently disfigured Robert Burgett’s foot, he and his wife turned to this Court for answers. Based on various products liability theories, the Burgetts believe that four defendants — Troy-Bilt LLC, MTD Products, Inc., Lowe’s Home Improvement, LLC, and Lowe’s Home Centers, Inc.— caused their injuries. These defendаnts have moved for summary judgment, claiming that they are not the malefactors the Burgetts seek. Because gaps riddle the Burgetts’ evidence in support of their claim, the Court will grant the defendants’ motion.
BACKGROUND
The Burgetts live in Belfry, a town in the undulating hills of eastern Kentucky. R. 110 at 1. Like all good neighbors, they keep their yard tidy. For years, Robert Burgett cut his grass with a riding mower; never once did he encounter a problem. Id. Just over a year ago, this changed. Burgett was mowing his lawn when the mower allegedly tipped back and threw him from his seat. Id. Burgett сlaims that the driverless mower turned 180 degrees and charged downhill toward him.
The Burgetts believe that an electrical defect caused one of the mower’s critical safety features, the operator presence control switch, to fail. R. 110 at 2. Under
The Burgetts hired оne expert witness, Jay Nogan, to testify at trial, but the Court excluded his testimony. R. 110. The defendants now challenge the sufficiency of the Burgetts’ remaining evidence in separate motions for summary judgment. R. 94; R. 98. The Court held a hearing on these motions, ordered supplemental briefing, and now issues its opinion in this case. See R. 111.
DISCUSSION
Summary judgment is warranted if the pleadings, discovery and disclosure materials, and affidavits show that there is “no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed.R.Civ.P. 56. To prevаil, the defendants must demonstrate that undisputed evidence forecloses the Burgetts’ claims or that the Burgetts cannot support their claims with admissible evidence. Celotex Corp. v. Catrett,
I. Summary Judgment Is Justified on AH of the Burgetts’ Claims Against MTD and Troy-Bilt.
MTD and Troy-Bilt challenge the Burgetts’ five claims: (1) defective design on a negligence theory; (2) defective design on a strict liability theory; (3) defective manufacture; (4) failure to warn; and (5) loss of consortium. See R. 94-1. The record is devoid of evidence supporting key elements of the first three claims. The Burgetts concede their fourth claim, and their final claim cannot survive in the absence of an underlying tort. So, the Court must enter summary judgment against the Burgetts.
A. Trоy-Bilt and MTD Are Entitled to Summary judgment on the Design Defect Claims.
The Burgetts allege that Troy-Bilt and MTD designed a defective product, R. 1-3 at 8-10. Without evidence of causation or that the design was unreasonably dangerous, their claim cannot survive summary judgment.
A plaintiff bringing a design defect claim must demonstrate two things. First, the product’s manufacturer must have breached its duty to use reasonable care to guard against foreseeable dangers. Ostendorf v. Clark Equip. Co.,
Second, the defect must have been a substantial factor in bringing about the plaintiffs harm — in other words, a legal cause of his injury. Templeton v. Wal-Mart Stores East, LP, No. 08-169,
The parties dispute whether the plaintiffs need expert testimony to stave off summary judgment on their design defect claim. In most design defect cases, expert testimony plays a crucial role in establishing breach of duty and causation. See Thomas v. Manchester, No. 03-705,
Unreasonably Dangerous: Because of the mower’s complex design, the Burgetts need additional evidence or expert testimony to support their claim that MTD and Troy-Bilt breached their duty to protect against foreseeable' dangers and designed an- “unreasonably dangerous” product. See Ostendorf,
In the first place, the Burgetts have not actually identified a design defect, and they are groping in the dark without expert tеstimony. The mower is a complex piece of machinery. Its electrical system is intricate. The Court itself would be unable to make heads or tails of a diagram of its electrical system without assistance. Almost any defect — barring something painfully obvious — would require scientific or specialized knowledge to understand. See Templeton,
Furthermore, the record contains no admissible evidence that an alternative design would have made MTD and TroyBilt’s product safer. See Ostendorf,
Causation: The Burgetts lack evidence to establish another element of their claim, causation. Kentucky law requires them to show that their circumstantial evidence makes it probable, rather than merely possible, that the alleged design defect caused their injury. Holbrook, 458 S.W.2d at 157-58. In this case, the parties have proposed multiple possible causes for the Burgetts’ injury. Accordingly, the Burgetts -must “eliminate[] those causes for which [MTD and TroyBilt] would not be liable” in order to tip the balance from possibility to probability. Siegel,
Where there is only one defendant, a plaintiff can allege multiple theories and still meet this standard. Consider this scenario: Tony’s water heater explodes, flooding his basement and destroying his belongings. Direct evidence of what happened is in short supply, but the cirсumstances indicate that the accident happened because of a problem with one of the heater’s pipes. Tony suspects that Heaters-R-Us designed a defective heater, but he also cannot rule out the possibility that Heaters-R-Us forgot a valve when it manufactured Tony’s particular heater. So, while Tony has circumstantial evidence to support the causation element of both his design defect and manufacturing defect claims, he cannot say with certainty which claim аgainst Heaters-R-Us is the correct one. Under Kentucky law, if Tony’s circumstantial evidence makes it probable that Heaters-R-Us’s tortious behavior caused his injury, he need not winnow his two claims to one to survive summary judgment. See id. (rejecting a directed verdict where circumstantial evidence equally supported design defect and manufacturing defect claims against the same defendant).
The Burgetts allege a considerably more complicated scenario: they believe that a second pair of defendants, the two Lowe’s entities, also independently caused their injury. R. 1-3 at 10. In other words, imagine that Tony brings a design defect claim against Heaters-R-Us and a negligent assembly claim, involving the same water heater, against Slapdash Factory. Once again, the same circumstantial evidence buttresses the causation element of both claims. To proceed against Heaters-R-Us solely on the basis of circumstantial evidence, Tony would have to eliminate all causes for which Heaters-R-Us is not liable. See Siegel,
■ Kentucky courts have not squarely addressed whether a plaintiff can satisfy the causation element of alternative tort claims against two separate defendants with the same circumstantial evidence. The reasoning in single-defendant eases, however, suggests that Kentucky law would not permit a plaintiff to proceed against two defendants under these circumstanсes.
Even if this were not true, the Burgetts’ attempt to establish causation would crumble for another reason: they need an expert witness. At trial, the jury would have to weigh a weltеr of potential causes. For example, Burgett could have driven the mower up too steep a slope. See, e.g., R. 94-1 at 19. Or, as Burgett first reported, he could have simply run over his own foot. R. 94-1 at 11. Or, a third party could have tampered with the mower. See R. 113 at 4. To eliminate alternative causes, the jury would have to answer tricky electrical engineering and biomechanical questions — questions far beyond the ken of ordinary persons. See Temple-ton,
The dearth of evidence for these two key elements of the Burgetts’ design defect claim means that the Court must grant summary judgment on this claim to MTD and Troy-Bilt.
B. Troy-Bilt and MTD Are Entitled to Summary Judgment on the Manufacturing Defect Claim.
The Burgetts’ inability to establish causation also defeats their theory that a manufacturing defect caused their injury. To prevail on a manufacturing defect claim, a plaintiff must show that the prod
The Existence of a Manufacturing Defect: Drawing all reasonable inferences in the Burgetts’ favor, a jury could find the existence of a manufacturing defect in the mower’s seat switch or wiring harness. Unlike in a design defect case, a manufacturing defect plaintiff need not “establish precisely why the [product] failed, but whether it did,” to" withstand summary judgment. Siegel v. Ky. Farm Bureau Mutual Ins. Co., No. 08-429,
The Burgetts’ circumstantial evidence creates such material issues of fact. True, Nogan’s now-excluded expert report contained much of the Burgetts’ evidence of the alleged manufacturing defect. However, the Burgetts can draw on other evidence for their claim that the mower failed duе to intrinsic causes. See Siegel,
Causation: All products liability theories, including design defect and manufacturing defect, share the same requirement that the product be a legal cause of the alleged harm. See Holbrook,
Since the Burgetts cannot support the elements of breach and causation, the Court must grant MTD and Troy-Bilt’s motion for summary judgment on the manufacturing defect claim.
C. The Burgetts Have Abandoned Their Failure To Warn Claim, So Summary Judgment Is Warranted.
The Burgetts have elected not to pursue their claim that MTD and Troy-Bilt failed to warn consumers adequately of the dangers associated with riding mowers. R. 101 at 40. The Court will thereforе grant summary judgment on this claim to MTD and Troy-Bilt.
MTD and Troy-Bilt assert, and the Burgetts do not contest, that Kentucky law requires the apportionment of fault among all parties, including Robert Burgett. See Ky.Rev.Stat. § 411.182; R. 94-1 at 36-38; R. 101 at 40. Because the Court has granted summary judgment to MTD and Troy-Bilt on all of the Burgetts’ claims, the Court need not reach this argument.
E. Donna Burgett’s Loss-of-Consortium Claim Fails Because the Court Has Granted Summary Judgment on All Other Claims.
Robert Burgеtt’s wife, Donna, has sued MTD and Troy-Bilt for loss of consortium due to her husband’s injuries. Under Kentucky law, loss of consortium is a separate cause of action, but it is “derivative” of the underlying claim. Boggs v. SM Co., No. 11-57,
II. The Burgetts’ Claims Against Lowe’s Do Not Survive Summary Judgment.
Lowe’s seeks summary judgment on the Burgetts’ negligent assembly and loss of consortium claims. See R. 98. These claims, like the Burgetts’ claims against MTD and Troy-Bilt, fail for want of evidence in the record to establish a breach of duty and causation.
A. Lowe’s Is Entitled to Summary Judgment on the Burgetts’ Negligent Assembly Claim.
The Burgetts claim that Lowe’s negligently assembled the mower and trained its employees in assembly techniques. R. 1-3 at 10. They allege that this negligence was a direct and proximate cause of their injuries. Id. Under Kentucky law, a negligence claim requires the plaintiff to establish that (1) the defendant owed the рlaintiff a duty of care; (2) the defendant breached its duty; and (3) this breach proximately caused the plaintiffs damages. Mullins v. Commonwealth Life Ins. Co.,
Breach оf Duty: According to Lowe’s, there is no evidence drawing a connection between the mower’s assembly and any alleged defect in its seat switch. R. 98-1 at 22-23. The Burgetts, as discussed above, have been unable to pinpoint the location of the mower’s alleged defect. See supra Part I.A. Still, the Burgetts identify five additional factors that they believe justify a finding that Lowe’s breached its duty. R. 103 at 26.
These five factors are of dubious relevance, so they do not add up to a genuine factual dispute that precludes summary judgment. First, the Burgetts present deposition testimony from Billy Cantrell, a Lowe’s product assembler. Id. Cantrell
Second, the Burgetts state that Lowe’s did not provide a pre-delivery inspection form, which typically catalogues any аssembly-related problems, with the mower at the time of its purchase. Id. at 27. No evidence in the record actually establishes the truth of this allegation. Cf R. 99-5 at 12 (stating that it was standard practice to give out PDI forms at Lowe’s). And, even if Lowe’s did lose the PDI form, this proves nothing about the assembly process itself; it shows only that Lowe’s failed to keep proper records.
Third, the Burgetts point to testimony from Robert Burgett that a Lowe’s employee inappropriately instructed him to use ether or starting fuel when he had trouble starting his mower. R. 103 at 27. This too is irrelevant: the instructions occurred over a month after Lowe’s assembled and inspected the mower. R. 108 at 4. Moreover, the Burgetts have not shown that anything in the assembly process might have affected the mower’s engine, and they do not explain how their one-time difficulty starting the engine relates to Robert Burgett’s accident. See R. 103 at 27. Fourth, they advert generally to the deposition of Lisa Daniels, a former Lowe’s employee, but they never describe how her testimony supports their claim. See id. at 28. The Court is at a loss to understand the relevance of Daniels’s testimony and has no obligation to connect the dots for the Burgetts. McPherson v. Kelsey,
Finally, the Burgetts allege that the mower once ejected a clip, which they later learned was designed for shipping purposes and should have been removed at assembly. R. 103 at 28. During oral argument, counsel for the Burgetts stated that the clip is direct evidence of an assembly error, which in turn constitutes circumstantial evidence that Lowe’s made a specific аssembly mistake related to the seat switch. This argument strains logic. There is no evidence that the clip came from the seat or from anywhere near the seat switch. Indeed, the parties could not verify at oral argument whether Lowe’s assemblers ever had cause to touch a seat switch when unpacking a mower for sale.
Causation: Even if there were a genuine dispute of material fact as to the alleged breach, no such dispute exists as to the issue of causation. The Burgetts do not have the direct evidence to show that an assembly error caused their injury. Their limited circumstantial evidence does not help them eliminate MTD and TroyBilt’s actions as a potential cause of their injury. Cf. supra Part I.A. (discussing the requirement under Kentucky law that a party relying on circumstantial evidence to prove causatiоn eliminate all other possible causes). Expert testimony might have bridged the gap, but the Burgetts no longer have that at their disposal. See id.; Templeton,
Two essential elements of the Burgetts’ negligent assembly claim are unsupported by the record. For this reason, thе Court must grant summary judgment to Lowe’s.
B. Lowe’s Is Entitled to Summary Judgment on the Burgetts’ Loss of Consortium Claim.
Robert Burgett’s wife, Donna, has also sued Lowe’s for loss of consortium due to her husband’s injuries. Because the Court has granted summary judgment on the underlying negligent assembly claim, her loss-of-consortium claim must fail. See Boggs,
CONCLUSION
Accordingly, it is ORDERED that:
(1) MTD Products, Inc., and Troy-Bilt LLC’s motion for summary judgment, R. 94, is GRANTED.
(2) Lowe’s Home Improvement, LLC, and Lowe’s Home Centers, Inc.’s motion for summary judgment, R. 98, is GRANTED.
(3) All pending deadlines are CAN-CELLED, and the Clerk shall STRIKE this matter from the Court’s active docket.
(4) The Court shall enter a separate judgment.
Notes
. The precise details of the acсident remain unsettled. For example, a doctor’s report from the day of the accident states that Burgett "put his right foot out for balance and ran over his right foot with his mower.” R. 94-1 at 11.
. According to the Burgetts, the Court need not engage in this analysis. Kentucky law permits the apportionment of liability among multiple tortfeasors. Ky.Rev.Stat. § 411.182. The Burgetts believe that the apportionment statute allows them to bypass summary judgment without first showing that they can support the causation element of each of their claims with admissible evidence. See R. 114. This misinterprets the law. To reach the point where apportionment of liability matters, the Burgetts must first prove their case against each defendant individually. See Owens Coming Fiberglas Corp. v. Parrish,
. This does not mean, of course, that a plaintiff can never allege products liability claims against multiple defendants. A plaintiff could, for example, have direct evidence of cаusation by two separate defendants. Or the plaintiff could have circumstantial evidence that points to two torts operating in tandem. Imagine Tony has proof — whether direct or circumstantial, it matters not — that Heaters-R-Us's design came directly from Victorian England and never evolved to meet modern American manufacturing standards. He has separate evidence that Slapdash Factory accidentálly sliced through a wire when building his water heater. Tony's theory is that the assembly defect exacerbated various design defects, resulting in the explosion that destroyed his heater. His claim could survive summary judgment where the Burgetts’ claims cannot.
. During oral argument, the Burgetts claimed that the missing PDI form entitled them to a missing evidence instruction at trial. This would permit the jury to infer that Lowe’s had not followed its standard assembly procedure. While the Burgetts might be correct under Kentucky law, see One Beacon Ins. Co. v. Broadcast Development Group, Inc.,
. As clarification, recall Tony’s claim against Slapdash Factory. Say Tony believes that his water heater exploded because of a problem with a pipe at the top of the tank, and Slap
