Pennsylvania Supreme Court Rules that Evidence of Product’s Compliance with Governmental Regulations or Industry Standards Is Inadmissible in Design Defect Cases to Show a Product Is Not Defective Under the Risk-Utility Theory.

Michael and Melissa Sullivan v. Werner Company, et al., No. 18 EAP 2022, 2023 WL 8859656 (Pa. 2023)

January 1, 2024

by Oswald P. Clark

The plaintiff was injured at a jobsite when the platform of a six-foot tall mobile scaffold collapsed, causing him to fall through the scaffold to the ground. The plaintiff, along with his wife, brought suit, alleging the mobile scaffold system was defectively designed because it was possible for a user to inadvertently rotate the deck pins off the platform during normal use. 

The trial court ruled, prior to trial, that evidence of the product’s compliance with OSHA and ANSI standards was inadmissible in a design defect case to show a product is not defective under the risk-utility theory. During deliberations, the jury asked the court, “[d]oes OSHA inspect every product that is put on the market, especially those with patent?”, but the court responded that it could not answer the question and instructed the jury not to consider OSHA in any way during its deliberations. The jury was also permitted to physically inspect an exemplar scaffold, but defense counsel was required to cover the ANSI and OSHA certification stickers with exhibit stickers so the jury would not be permitted to see that the product was in compliance. 

On appeal, the Superior Court affirmed the trial court’s ruling that compliance with industry and governmental standards is inadmissible. The Pennsylvania Supreme Court has now weighed in, agreeing with the trial and Superior Courts that evidence of a product’s compliance with governmental or industry standards is inadmissible because it is irrelevant and would confuse the jury. 

This case highlights that Pennsylvania courts are unwilling to move towards the Third Restatement, as have virtually all of Pennsylvania’s sister states. Chief Justice Todd’s dissent succinctly highlighted the problems with the decision, stating that the majority opinion “perpetuates a vestige of the highly criticized and recently overruled decision in Azzarello v. Black Brothers Co., Inc.; eschews the recent teachings of this Court in Tincher v. Omega Flex, Inc.; rejects the sound approach taken by virtually all of our sister states; accepts the patent unfairness of nonetheless allowing such evidence to be admissible in a plaintiff’s case to show a product is defective; and deprives juries of potentially valuable and relevant information, all seemingly out of a misplaced fear that the jury will be misled or confused.”

The Ohio Supreme Court Extends Sham-Affidavit Rule to Contradictory Expert Reports

Legal Roundup: Ohio In its June 23, 2026, decision in Moore v. Mercy Medical Center, the Ohio Supreme Court upheld a trial court’s decision to strike an expert witness’s affidavit that contradicted the opinions expressed in the expert’s prior report. This case pertains to allegations of medical malpractice after plaintiff Cheri Moore gave birth to an infant in respiratory distress who required intubation. Moore alleged that a delay in ordering an emergency cesarean section resulted in the need for intubation, causing her child’s injuries. Specifically, Moore sued Dr. Meniru, who completed his first shift at 7:00 a.m. on May 28, 2015, and did not resume treating Moore until 7:00 a.m. on May 29, 2015. One of Moore’s expert witnesses authored a report stating that the doctors, including Dr. Meniru, deviated from the standard of care by not advocating for a cesarean section in the evening of May 28, 2015. Based on this report, Dr. Meniru moved for summary judgment, arguing that the alleged breach occurred during a period when he was not on duty. In response to the summary judgment motion, the plaintiff filed an affidavit from the same expert. Although the expert expressly incorporated his previous report into his affidavit, he also offered an additional opinion: that Dr. Meniru breached the standard of care by failing to begin a cesarean section within 30 minutes of receiving reports of fetal distress. Dr. Meniru filed a motion to strike the expert’s affidavit, arguing that it contradicted the opinions set forth in his prior report in violation of the sham-affidavit rule. The sham-affidavit rule applies to “a contradictory affidavit that indicates only that the affiant cannot maintain a consistent story, or is willing to offer a statement solely for the purpose of defeating summary judgment”. Moore, supra, at ¶ 19, citing Pettiford v. Aggarwal, 126 Ohio St.3d 413, 2010-Ohio-3237. The trial court granted both the motion to strike and the motion for summary judgment, and the Fifth District affirmed. The Ohio Supreme Court accepted two questions of law: (1) whether the sham-affidavit rule applies when the sworn testimony contradicts prior unsworn statements; and (2) whether an inconsistency within the affidavit goes to credibility or admissibility, justifying an order striking the affidavit. Previous rulings by the Ohio Supreme Court regarding the sham-affidavit rule have pertained to contradictions between an affidavit and sworn deposition testimony. See, e.g., Byrd v. Smith, 2006- Ohio-3455, 110 Ohio St.3d 24, 850 N.E.2d 47. However, here, the Court was asked to apply the same rule to contradictions between a sworn affidavit and an unsworn expert report. The Court held that, because Moore’s expert incorporated his prior report into his affidavit, he effectively adopted the report as part of his sworn testimony.

Pennsylvania Superior Court Reaffirms Liberal Pleading Standard in Medical Malpractice Actions

Legal Roundup: Pennsylvania The Pennsylvania Superior Court has reinforced a broader fact-pleading approach that may make it more difficult for health care defendants to obtain dismissal at the preliminary objection stage. In DaSilva v. Abington Memorial Hospital, the court held that the plaintiffs’ second amended complaint satisfied Pennsylvania’s fact‑pleading requirements despite the absence of individually named negligent actors. In DaSilva, the plaintiffs filed a second amended complaint alleging that Abington Memorial Hospital was directly and vicariously negligent after the patient, who was experiencing a mental health crisis, was left unattended by hospital staff, exited the emergency department, and was struck by a vehicle, suffering serious injuries. The trial court sustained the hospital’s preliminary objections and dismissed the complaint with prejudice, stating plaintiffs “failed to plead any material factual allegations in support of their claims of negligence [and] set forth vague allegations of negligence and unidentified agency.” Id. at *5. The plaintiffs appealed. On appeal, the Superior Court reversed, holding that the complaint sufficiently pled negligence and vicarious liability claims under Pa.R.C.P. 1019(a). The court concluded that allegations describing the patient’s condition, the hospital’s awareness of that condition, and the alleged failure to monitor or prevent elopement were adequate to satisfy Pennsylvania’s pleading requirements. Significantly, the court rejected the hospital’s argument that the complaint failed because it did not identify the specific employees responsible for the alleged negligence. Instead, the court found that generalized references to “emergency room staff” were sufficient to place the hospital on notice of the claims because “the names of those who performed services for the plaintiff are known to the defendant or can be ascertained during discovery.” Id. at *12 (citing Est. of Denmark ex rel. Hurst v. Williams, 117 A.3d 300, 307 (Pa. Super. 2015)). The effect of DaSilva is that plaintiffs may proceed past the pleading stage with relatively generalized allegations, particularly in cases involving institutional defendants where relevant details are uniquely within the defendant’s control. As a result, health care defendants should anticipate that challenges to claim sufficiency may be resolved in the later stages of litigation, including discovery and summary judgment.
