An unexpected defense verdict predicts bargaining information, not the outcome of the next case. Bellwether trials are sample test cases in federal multidistrict litigation (MDL) tried to educate the court and parties about jury reception of shared claims and defenses, according to Bloomberg Law's review of bellwether selection.
The recent formula example shows the limit. On August 31, 2026, a Chicago federal jury returned a full defense verdict for Mead Johnson in Inman v. Mead Johnson, the first federal bellwether to reach verdict in the cow's-milk formula NEC litigation.

What the formula defense verdict decided
The jury rejected claims that Enfamil Premature was defectively designed and that Mead Johnson failed to warn about necrotizing enterocolitis risk in a premature infant's death, according to Steptoe's report on the Inman verdict. That decision resolved liability and damages for that family alone. It did not declare the product safe for all infants.
The same report said more than 800 complaints against Mead Johnson or Abbott remained pending in MDL No. 3026. Those families still must prove their own medical history, product use, warning, and causation.
Why one trial does not control hundreds of cases
A bellwether is meant to produce reliable information about other centralized cases, but the Federal Judicial Center's 2019 guide says bellwethers generally have no preclusive effect on other cases, as described in the Center's MDL bellwether guide. A win or loss does not automatically decide the next file. Each remaining plaintiff keeps a separate burden of proof.
That rule matters most after a surprise. A defense verdict may test a theory, a warning document, an expert, or a difficult medical history. It does not erase different facts in the next child's feeding record, diagnosis, or outcome.
Why the next verdict can look very different
Small samples swing. In Bard PowerPort MDL 3081, the first bellwether ended in a defense verdict on failure-to-warn and fraud claims with a hung jury on design defect, while the second produced a unanimous 40 million dollar plaintiff verdict on design defect and failure to warn, according to MDL Update's bellwether-trial tracker. One docket produced opposite signals within months.
Bloomberg Law, summarizing research by Fallon and others and critique by Beck and Herrmann, warns that bellwethers poorly predict the mass when selected cases are stronger or weaker than the docket. Tiny samples and large case-to-case variation provide little statistically meaningful guidance. Injury severity, treating doctors, documents, state law, and jury views can change everything.
How families should use bellwether results
Parties use bellwether verdicts as settlement data rather than binding outcomes. Steptoe called the Mead Johnson defense verdict only a signal for hundreds of remaining MDL and state-court NEC cases.
Lawyers adjust value ranges, pick stronger next cases, fix weak expert testimony, and renegotiate. If you have a possible claim, treat each verdict as information:.
- Keep feeding records, NICU records, diagnoses, bills, and product names together.
- Do not assume your deadline changed because one trial ended.
- Ask your lawyer whether your facts resemble the tried case or a later scheduled case.
- Watch several verdicts before judging settlement value, then ask how the next scheduled bellwethers match your injury history.
