Plaintiff Shoots an Airball Against Nike in Design Defect Case

Share

In the wake of March Madness, it is only appropriate to call attention to an opinion laced with pithy basketball puns. In Nachimovsky v. Nike, Inc. et al., 2022 WL 943421 (E.D.N.Y. Mar. 29, 2022), Plaintiff injured his knee during a recreational basketball game. Blaming this injury on his new sneakers, he called foul and brought claims for negligence and products liability—specifically design defect—against Nike, which designed and manufactured the sneakers, and Shoe Fitters, which sold the sneakers.

To support his claims, Plaintiff proffered two one-page letters from a podiatrist who concluded that the sneakers were defective and a “major contributing factor” to Plaintiff’s injury. Nike (and Shoe Fitters, by incorporation) responded with a full-court press, seeking to exclude the podiatrist’s opinions under Federal Rule of Evidence 702, arguing that they were not reliable and he was not qualified to offer them.

Snapchat’s ‘Speed Filter’: Georgia Supreme Court Revives Negligent Design Claim

Share

On March 15, 2022, the Georgia Supreme Court revived a negligent design claim that had been brought against Snapchat, Inc. (n/k/a Snap, Inc.) involving Snap’s “Speed Filter.”  As one of the few decisions across the country addressing products liability law in the context of platform “products” (more accurately categorized as services) such as Snapchat, the opinion provides a glimpse of the sort of issues that other courts may soon be required to address.

The Factual & Procedural Background:

Plaintiffs Wentworth and Karen Maynard alleged that Defendant Christal McGee was using Snapchat’s “Speed Filter” and driving over 100 miles per hour when she rear-ended them, causing severe injuries.  The “Speed Filter” is a feature that allows the user to record their real-life speed on a photo or video and share it with other users.  Plaintiffs sued Snap as well, alleging that Snap had negligently designed the “Speed Filter” because the filter promoted unsafe driving and encouraged dangerous behavior.

The Rule 702 Toolbox: Cherry-Picking Is a Recipe for Exclusion

Share

Most courts (but certainly, and unfortunately, not all of them) recognize that cherry-picking is a cardinal sin under Rule 702.  Science generally requires a rigorous and conservative approach to evaluating cause-and-effect relationships.  This schema inherently clashes with litigation, an arena where parties prioritize results over neutral principles of process purity.

“Cherry-picking” involves the selective consideration of facts and data to support a desired or pre-determined result, rather than the analysis of all relevant facts and data to find a scientific truth (or determine that the truth remains elusive based on the available facts and data).  It evades the scrupulous adherence to principles of objectivity, rigor, and process validity that are the hallmark of the scientific method.  In Daubert-speak, such a methodology does not produce “scientific knowledge.”  Rather, cherry-picking represents a failure of methodology that cannot be waived off as a matter of weight rather than admissibility.

The Rule 702 Toolbox: How Do You Solve a Problem Like the Ninth Circuit?

Share

There has been much discussion recently about how Rule 702 is in need of a tune-up to better guide district courts’ gatekeeping.  More about that soon.

But a case now pending before the Supreme Court, Monsanto Company v. Hardeman, No. 21-241, demonstrates that it’s not always the fault of the district courts.  (Disclaimer:  This firm (and this author) filed an amicus brief supporting certiorari.)  Sometimes it’s about a lack of stewardship at the circuit level.  Absent direct and unequivocal guidance from the Supreme Court, appellate courts call the tune, and the district courts are required to follow it.  And in the interstices, district judges read the tea leaves and try to follow the circuit court’s leads and signals.  No one likes to get reversed.  Even if the district judges think the circuit has gotten it wrong, they honor the hierarchy and follow the commands of stare decisis, human nature and common sense.

Southern District of Texas Holds Learned Intermediary Doctrine Applies to Clinical Trials

Share

Does the learned intermediary doctrine apply in the context of a clinical trial?  According to the Southern District of Texas, it does.  The case in question is Butler et al. v. Juno Therapeutics, Inc., a tragic case involving the death of a 19-year-old woman with terminal leukemia who died within days of receiving an experimental cancer drug as a participant in a clinical trial.

In 2015, Juno Therapeutics (Juno) was developing a treatment for advanced blood cancers involving Chimeric Antigen Receptor T-cell (CAR-T) therapy.  CAR-T therapy is designed to modify a patient’s white blood cells to target cancer cells with the goal of improving the patient’s condition so a bone marrow or stem cell transplant can be tolerated.  In October 2015, Juno entered into a Clinical Study Agreement with MD Anderson (and other hospitals) as part of a Phase 2 clinical trial (the “Rocket Study”) of a drug identified as JCAR015, a CAR-T therapy.  Drs. William Wierda and Michael Rytting were the principal investigators of the Rocket Study at MD Anderson.

Not All’s Well That Ends Well: The Seventh Circuit Misapplies Daubert, but Still Delivers a Victory

Share

The nature of advocacy makes it hard sometimes for lawyers to focus solely on the outcome and the bottom line result.  How a court gets there may not matter much to the prevailing party in the dispute as they celebrate the win, but it may have an impact on later cases.  A recent example is the opinion in Burton et al. v. E.I. DuPont de Nemours and Co., Inc., 2021 WL 1422814 (7th Cir. Apr. 15, 2021).  The court found the winner’s circle, but it dented the car a bit along the way.

[Disclosure/disclaimer:  The author filed an amicus brief in support of defendants in the case.]
