How the NEC MDL Was Formed

As NEC formula cases were filed across multiple federal districts beginning in 2021 and accelerating through 2022, the United States Judicial Panel on Multidistrict Litigation (JPML) determined that centralization was warranted. In October 2022, the JPML established MDL No. 3026, consolidating cases from across the country in the Northern District of Illinois — chosen in part because of its proximity to Abbott's corporate headquarters in North Chicago and the large volume of NEC cases filed in the Chicago area. Chief Judge Rebecca R. Pallmeyer was assigned to manage the MDL. A Plaintiffs' Steering Committee (PSC) of experienced plaintiffs' attorneys was appointed to lead discovery and coordinate the litigation on behalf of all plaintiffs.

The Bellwether Trial Program

Bellwether trials are a core feature of MDL management. Rather than trying thousands of individual cases separately, the MDL court selects a small number of representative cases — bellwethers — to be tried before actual juries. The results of these trials provide critical information: they reveal how juries respond to the evidence, which liability theories resonate, what damages juries award, and how credible the expert witnesses on both sides are. This information then drives settlement negotiations for the remainder of the MDL. In MDL 3026, bellwether trials have produced substantial plaintiff verdicts — including the Ndambi case verdict against Abbott of $65 million in July 2024 — that have significantly influenced the settlement discussions ongoing in 2025 and 2026. Additional bellwether trials are scheduled, and the results will continue to shape the resolution of remaining cases.

How Your Individual Case Fits Into the MDL

When your attorney files your NEC case in federal court, it will be transferred to MDL 3026 in the Northern District of Illinois. Your case is assigned a separate docket number and a Long Form Complaint specific to your child's facts is filed within the MDL. Your case participates in MDL-wide discovery — meaning Abbott and Mead Johnson must respond to discovery requests that benefit all plaintiffs, and depositions and document productions apply to your case. Your case may be selected as a bellwether trial, or it may be resolved through settlement as part of a global or individual resolution. Cases that are not resolved in the MDL may eventually be remanded to your home federal district for individual trial. You will have your own attorney throughout this process — MDL consolidation does not mean all plaintiffs share a single attorney.

State Court Cases Outside the MDL

Not all NEC formula cases are in the federal MDL. Plaintiffs who prefer to sue in state court — often because of more favorable venue rules, SOL considerations, or state-specific tort law advantages — may file in state court. Missouri, Illinois, and Texas state courts have seen particularly active NEC formula litigation, including the major Mead Johnson verdicts discussed elsewhere on this site. Some attorneys file in both state and federal court to preserve options. The strategic choice between state and federal court depends on multiple factors including the specific facts of the case, the state's product liability law, applicable SOL, and the litigation posture. Your attorney will advise you on the appropriate venue.

Necrotizing Enterocolitis (NEC) is a life-threatening inflammatory disease of the intestines that primarily strikes premature and low-birthweight infants in the Neonatal Intensive Care Unit. In NEC, bacteria invade the immature intestinal wall, causing progressive tissue death (necrosis), which can lead to bowel perforation, bacterial sepsis, and multi-organ failure. NEC kills approximately 15,000 premature infants in the United States each year and is the leading cause of death from gastrointestinal disease in the NICU. Survivors often face lifelong consequences including Short Bowel Syndrome, TPN dependency, and neurodevelopmental disabilities.
