Expert’s Failure to Identify Product Defect in Pressure Cooker or Inadequacy in Warnings Leads to Summary Judgment

It is axiomatic that a plaintiff must offer evidentiary support for each element of her claim in order to survive summary judgment. And a ubiquitous feature of product liability actions is the use of expert witnesses by both sides. These principles are, of course, related – the plaintiff usually must offer expert testimony in order to make a prima facie case, and the defense then attacks that prima facie case through expert testimony. But sometimes a plaintiff loses sight of the connection and, despite retaining an expert, fails to elicit the opinions she needs to make her case. As a recent decision from the Western District of Wisconsin illustrates, it pays for a defendant to carefully evaluate whether a plaintiff has checked all of the necessary boxes.

In Moore v. National Presto Industries, Inc., 2022 WL 1555875 (W.D. Wis. May 17, 2022), Plaintiff alleged that she was injured when she opened her pressure cooker while it was still pressurized, ejecting its contents onto her arm, causing burns. Plaintiff sued the cooker’s manufacturer, asserting strict liability claims for design defect and failure to warn as well as a claim for negligence. Defendant moved for summary judgment on each of these claims.

Passengers on Litigation Tourism Train Get Review from Supreme Court

The United States Supreme Court will soon consider whether the due process clause of the Fourteenth Amendment prohibits a state from requiring that a corporation consent to personal jurisdiction in order to conduct business there.

The question arises from a Pennsylvania Supreme Court case, Mallory v. Norfolk Southern Railroad Co., 266 A.3d 542 (Pa. 2021), which we wrote about here.  In Mallory, plaintiff Robert Mallory attempted to hold the Norfolk Southern Railway Co. liable for the colon cancer he allegedly developed after being exposed to chemicals during the two decades that he worked for the railroad in Virginia and Ohio.

It’s an MDL World: Agreement is enough, or is it?

The JPML held its second hearing of 2022 at the end of March. We addressed the results of the first hearing recently here, and further observed the JPML’s trend over the course of the last several years in forming fewer MDL proceedings each year. As we move further into 2022, it is clear this trend has continued.

In April, the JPML formed two new MDLs out of four total petitions, bringing the cumulative total of new MDLs in 2022 to four (out of seven petitions considered)—well below the typical quarterly pace for new MDLs, including that of 2021. Through its orders, the JPML provided insights into the circumstances that justify MDL formation, and those that do not. We briefly discuss these orders below:

Updated EPA Analysis on Long-Term Health Effects of Formaldehyde Exposure Could Have Lasting Implications for Manufacturers

On April 14, 2022, the Environmental Protection Agency (EPA) released draft conclusions in a report updating its analysis regarding formaldehyde exposure, suggesting that long-term exposures to small amounts of formaldehyde in the environment can increase the risk of rare head and neck tumors, leukemia, and other threats to health. The conclusions are not final agency action. Still, manufacturers should be aware of the potential for EPA’s analysis to influence both regulation and litigation at both the state and federal levels.

For over a decade, there has been much debate and study on the long-term effects of exposure to formaldehyde. The EPA’s new analysis is an update of a 2010 draft EPA report that was heavily panned by scientists, legislators, and chemical manufacturers and that drove the EPA back to the drawing board. For example, the National Academies of Sciences, Engineering, and Medicine criticized the 2010 draft EPA report for failing to describe the rationale behind its methodology and failing to sufficiently support its conclusions.

Not Just a Rubber Stamp: FDA Revises Its 510(k) Refuse to Accept Policy

Is the decision to submit a 510(k) application versus a Premarket Application (PMA) at the sole discretion of a medical device manufacturer? The answer is not always clear to product liability lawyers, judges, and juries. FDA recently published revised guidance on its “Refuse to Accept Policy for 510(k)s” that reinforces and clarifies that the regulatory path may be analyzed multiple times by FDA before it clears a 510(k) device. This clarification underscores the reality that the type of application submitted is largely dictated by the agency, not the applicant. This post discusses some key takeaways from this new guidance before briefly discussing how this guidance may be implicated in medical device litigation.

It’s not what happened, but why: First Circuit rejects conclusory, unsupported expert opinions

It is not uncommon for an opposing expert to opine that the existence of injury alone implies negligence, nor is it unusual to find that such opinions are supported only by general reliance on “literature” with no discernible connection to the issue at hand. Certainly, Federal Rule of Civil Procedure 26(a)(2)(B) requires an expert’s report to contain “a complete statement of all opinions the witness will express and the basis and reasons for them.” And, Federal Rule of Evidence 702 requires that an expert not only base an opinion on sufficient facts or data but also reliably apply his or her methodology to those facts or data. Yet all too often, courts decline to hold an expert to task and instead find that these deficiencies go to the weight, but not the admissibility, of an expert’s opinion. But, as recently observed by the First Circuit, an expert must do more than merely cite the existence of an injury if a res ipsa loquitur argument is not available. And regardless, an expert’s failure to link the literature cited to the opinions offered is not a matter of insufficiency, but rather of unreliability.

In López-Ramírez v. Toledo-González, — F.4th —, 2022 WL 1261299 (1st Cir. 2022), Plaintiff experienced hearing loss, facial paralysis and loss of balance following a neurosurgical procedure performed by the defendant neurosurgeon. Plaintiff sued the physician and the hospital, alleging that the defendant neurosurgeon’s failure to properly evaluate, treat and monitor her condition during the surgery amounted to medical malpractice. In support of that claim, Plaintiff disclosed a neurology expert who opined that the defendant neurosurgeon deviated from the standard of care and included with his report articles from the medical literature that he felt “may be helpful” in understanding his opinions.
