This is a strict products liability case. Plaintiff/appellee Arthur B. Lee, an employee of Tyler Pipe Industries, Inc. from 1964 to 1972, became unable to work in 1985 due to a debilitating lung disease diagnosed as “silicosis.” It is undisputed that such disease was brought on by inhalation of tiny particles of air-borne silica, referred to herein as “silica flour,” which embeds itself in lung tissue, ultimately inducing the fibrotic lung disease known as silicosis.
It is likewise undisputed that Tyler Pipe is an employee-subscriber to workers’ compensation insurance, and that Lee’s exposure to the silica arose out of his employment at Tyler Pipe, and that his injuries were covered by workers’ compensation insurance under the Texas Workers’ Compensation Act.
The record reveals that Lee filed this suit on June 17, 1987, after the decision in Duncan v. Cessna Aircraft Co.,
Although this action was brought against Dresser on three legal theories of liability, viz, strict liability, negligence, and breach of implied warranty, the case was submitted to the jury on Lee’s strict liability theory. The jury found that “Dresser’s failure to warn of the danger [of silica] rendered] the silica unreasonably dangerous as marketed.” The jury found “such failure [was] a producing cause of the disease in question ... [silicosis].” The jury also found that Dresser’s silica product caused “96%” of Lee’s silicosis disease, and that the product of a settling tort-feasor, Pennsylvania Glass-Sand Corporation, caused “4%” of the disease.
Upon receipt of the verdict, the trial court signed and entered a judgment in favor of Lee against Dresser for the substantial damages found by the jury.
Dresser presents five points of error. It argues under its points of error that the trial court erred, (1) in refusing to submit its requested definitions of “negligence,” “ordinary care,” and “proximate cause”; (2) in refusing to submit its requested question inquiring about Lee’s negligence
There may be more than one proximate cause of an event, but if an act or omission of any person not a party to the suit was the ‘sole proximate cause’ of an occurrence, then no act or omission of any other person could have been a proximate or producing cause[;]
and (5) in excluding portions of the testimony of certain witnesses and excluding Dresser’s tendered exhibits numbers 6, 7, 8, 9, and 18 in respect to the conduct of Tyler Pipe and the requested sole cause instruction.
Because we conclude that the requested question regarding Lee’s negligence was not in substantially correct form, and because we conclude that the rule of Varela v. American Petrofina Co.,
In considering points one, two and three, we observe that McKisson v. Sales Affiliates, Inc., the court expressed “agree[me]nt with the Torts Restatement rule relating to contributory negligence as a defense to an action based upon strict liability, viz:
‘Contributory negligence of the plaintiff is not a defense when such negligence consists merely in a failure to discover the defect in the product, or to guard against the possibility of its exist*408 ence. * * * ’ ” § 402A [c]omment (n), Contributory Negligence.
McKisson,
The court in Duncan v. Cessna reaffirmed McKisson’s adoption of the “rule in § 402A comment n, of the Restatement (Second) of Torts, that negligent failure to discover or guard against a product defect is not a defense [in a strict liability action]” (citations omitted). Duncan,
Finally, we address Dresser’s points of error numbers four and five. Dresser argues that the trial court erred in excluding evidence “regarding Tyler Pipe’s conduct to support the sole cause defense and in denying the sole cause instruction.”
Assuming, without deciding, that generally, sole cause is a substantive defense in strict liability suits in which the plaintiff sues on theories of strict liability, negligence, and breach of warranty, see Duncan,
As Dresser notes, this Court has heretofore had occasion to deal with Varela. See W.B. Hinton Drilling Co. v. Zuniga,
We decline to follow Turlington for the same reasons we refused to follow Sap-pington and the other courts of appeals cases discussed by us in Hinton. Although we agree with Judge Garwood’s declaration in Turlington that the Texas Supreme Court in Varela held that “the employer’s negligence could not be con
At oral argument, we permitted Dresser to provide a citation of Allen v. Chance Manufacturing Co., Inc.,
We conclude that Varela prohibits the admission of the conduct of Tyler Pipe in this suit and the submission of the requested sole cause instruction. Hence, the trial court did not err in excluding evidence of Tyler Pipe’s conduct and in refusing to give the sole cause instruction to the jury. Dresser’s points of errors four and five are overruled.
The judgment is affirmed.
