This case is from the non-Butler Snow side of the blog.
It’s a relatively new term (at least for us Gen Xers) – but we have all been ghosted. A second date that never gets confirmed. A contractor who quotes the job and then vanishes. A group text that just stops. It stings, but usually the only casualty is your ego. In Sarmiento-Tenecela v. Teva Pharmaceuticals USA, Inc., No. ESX-L-002653-20, slip op. (N.J. Super. Ct. Law Div. Aug. 31, 2026), the casualty was the entire case.
Plaintiff sued over a Paragard IUD that fractured on removal a decade after it was placed, and she planned to prove her claims with two experts — David Kessler, the former FDA Commissioner and go-to plaintiff’s expert in pharmaceutical mass torts, and Dr. Jimmy Mays, a polymer chemistry PhD who has done general causation work in the Paragard MDL on the device’s materials and design. These are not fly-by-night witnesses pulled off a for-hire circuit. They are the same experts other Paragard plaintiffs have relied on nationwide. Small problem — neither one ever sat for a deposition in this case. Defendants asked for dates. Plaintiff did not respond. The court ordered depositions to happen by a date certain and warned that noncompliance could mean preclusion of expert testimony or worse. Plaintiff still did not produce them. When the motion for sanctions finally landed, plaintiff’s excuse amounted to “we could not reach them” and “counsel had a family medical situation.” The court was sympathetic to the latter as a human matter and unmoved by it as a legal one. You cannot rely on an expert to beat summary judgment while simultaneously keeping that expert unreachable for the other side. That is not litigation, that is hide and seek.
Plaintiff’s defense was that Kessler and Mays are general experts in the Paragard MDL and that plaintiff’s counsel does not control their calendars. That much may be true. These experts likely are booked across dozens of cases and answer to MDL leadership, not to any one plaintiff’s firm, but it cuts against plaintiff, not for her. Nationally prominent, frequently deposed experts are not hard to find or schedule; they have existing deposition protocols, standing availability windows, and counsel who negotiate their calendars as a matter of routine. Plaintiff also cited counsel’s mother’s hospitalization for cardiac procedures as a reason the deadline slipped. The court did not dismiss those circumstances, but it also did not let them do the work plaintiff needed them to do. Personal hardship might explain a missed phone call. It does not explain months of silence on a court-ordered deposition schedule, and it certainly does not explain why they could not be produced even after the court compelled compliance.
Defendants asked for dismissal outright as a sanction. The court declined to go that far, noting that dismissal as a discovery sanction is reserved for cases where the misconduct goes to the very foundation of the claim or is deliberate and contumacious. Id. at 5. Instead, the court went with the lesser remedy of preclusion. Id. at 6-7. Kessler and Mays were barred from offering testimony at trial. But benching the experts turned out to be the ballgame anyway because plaintiff needed them to survive summary judgment.
To defeat preemption of a failure to warn claim, a plaintiff has to show the manufacturer could have made a unilateral label change under the FDA’s changes being effected regulation (“CBE”). Which requires plaintiff to produce evidence of “newly acquired information” that reveals risks of a “different type or greater severity or frequency” than what was available to the FDA at the time of approval. Id. at 7. In this case that meant, plaintiff needed to show defendant possessed qualifying newly acquired information before plaintiff’s IUD was implanted in April 2008. She did not. The adverse event reports she pointed to were already reflected in the FDA-approved label before her IUD was placed, and a study done in 2015 was simply seven years too late to support a CBE label change before 2008. The court noted, tellingly, that it did not even know what Kessler would have said about newly acquired information as of 2008, because his MDL report never addressed the question. Funny how that works when you will not produce your expert for a deposition. The court found no genuine dispute of material fact and held the warning claims preempted. Id. at 18.
Plaintiff also argued the IUD’s breakage warning did not adequately cover fracture during routine removal without preexisting embedment. The court did not need to resolve that dispute because plaintiff’s only medical expert testified the device was in fact embedded at the time of removal. The precise risk plaintiff says the label failed to disclose is not the risk that happened to her. And having conceded she would not offer her case-specific medical expert on label adequacy at all, plaintiff was left with no warning expert whatsoever. Id. at 19.
The design defect claim fared no better. Plaintiff’s two design theories, the type of resin used and the barium sulfate concentration, required evidentiary support plaintiff simply did not have. She offered no evidence her own device used the disfavored resin, and no expert testimony that a different barium sulfate concentration would have prevented the fracture. Nor did she offer any expert evidence of a feasible alternative design. Under New Jersey law, a design defect claim without an alternative design is not a design defect claim. Id. at 18.
This is a defense win on preemption, but our focus is on the preclusion ruling. Discovery gamesmanship around expert witnesses has consequences, even when a court is not willing to nuke the whole case as an outright sanction. A plaintiff who will not make her experts available for deposition simply does not get to use them, full stop, and courts should not need to hear the phrase “we could not reach them” more than once before losing patience. Ghosting has consequences. In this case, plaintiff’s experts skipped the date, and the whole case got left standing at the altar.
