What is multidistrict litigation (MDL)? How breach lawsuits are centralized, defined

Multidistrict litigation (MDL) is the federal procedure under 28 U.S.C. § 1407 that transfers civil cases sharing common questions of fact, pending in different districts, to one district court for coordinated or consolidated pretrial proceedings. The Judicial Panel on Multidistrict Litigation (JPML) orders the transfer, and each case goes back to its original district when pretrial work ends, unless it has ended first.

How the panel decides

Section 1407 gives the decision to seven circuit and district judges, no two from the same circuit. The panel transfers when centralization will serve the convenience of parties and witnesses and promote the just and efficient conduct of the actions. Related suits filed later can follow the first group as tag-along actions.

A breach MDL in practice

The Change Healthcare cases show how one breach becomes one docket. The panel's transfer order, filed on 7 June 2024 according to the court record, centralized them as MDL No. 3108 in the District of Minnesota. The motion covered six actions in two districts; the panel then learned of 44 related actions in ten more, for 50 actions in twelve districts.

Minnesota was chosen because the parent company and two other defendants are headquartered there, with much of the evidence. Some plaintiffs asked to separate consumer suits from healthcare provider suits. The panel declined, holding that all the claims arise from the same breach and that the transferee court can run separate discovery and motion tracks, a point it drew from its 2014 order in the Home Depot breach litigation.

Why it matters to a CISO

An MDL puts the security program at the center of discovery. The panel expected discovery in every Change Healthcare action to examine how the system was breached, what security measures were in place, and what was done afterwards to notify those affected. Incident timelines, control evidence and notification records kept during a response can become the record one court reviews.

What it is not

An MDL is not a class action and not a merger of cases into one judgment. It is a pretrial arrangement. The suits inside it, in MDL No. 3108 proposed nationwide and statewide data breach class actions, keep their identity and return for trial unless resolved first.
