Multidistrict Litigation (MDL)

Multidistrict Litigation (MDL) is a federal court procedure that consolidates similar civil cases from multiple judicial districts into a single district court for coordinated pretrial proceedings. This mechanism streamlines the handling of cases that share common questions of fact, eliminating duplicative discovery and preventing inconsistent rulings across different courts.

The MDL process is governed by 28 U.S.C. § 1407 and managed by the Judicial Panel on Multidistrict Litigation (JPML), a seven-judge panel that determines whether cases should be consolidated and which district court should oversee the proceedings.

Once consolidated, cases remain in the MDL for pretrial matters including discovery, motion practice, and settlement negotiations, but individual cases can be remanded to their original districts for trial if necessary.

MDL proceedings begin when parties petition the JPML to consolidate cases or when the panel acts on its own initiative. The panel considers factors including common questions of fact, the convenience of parties and witnesses, and the promotion of just and efficient conduct of litigation.

The JPML selects a transferee court based on the location of parties, witnesses, and evidence, as well as the transferee judge's experience with complex litigation. The chosen judge becomes the MDL judge and oversees all consolidated cases.

Key participants include the MDL judge, court-appointed lead counsel, liaison counsel, a plaintiffs' steering committee, and defense counsel. Lead counsel coordinates the litigation strategy and represents the collective interests of all plaintiffs, while individual attorneys retain their attorney-client relationships with their specific clients and continue to advocate for their interests within the larger framework.

Opioid MDL (2017) — Consolidated litigation against pharmaceutical companies, distributors, and pharmacies related to the opioid crisis. Generated comprehensive settlement agreements exceeding $26 billion.

Volkswagen "Clean Diesel" MDL (2015) — Consolidated cases arising from VW's emissions scandal involving diesel vehicles with illegal defeat devices. Resulted in multi-billion dollar consumer and environmental settlements.

For class members, MDL proceedings offer both advantages and considerations that directly impact their legal experience. The primary benefit is efficiency—consolidated discovery and coordinated legal strategy often lead to faster resolutions and reduced litigation costs, which can translate to higher net recoveries for plaintiffs.

However, individual attention may be diminished as cases are managed collectively. Class members should stay informed about proceedings through their attorneys and understand that settlement decisions may be made by lead counsel and the court, though individual attorneys still advocate for their specific clients' interests.

Class members retain the right to object to settlements and may need to make individual decisions about participation. The MDL process can result in global settlements that provide structured compensation, but individual circumstances may warrant separate consideration during remand proceedings if cases return to their original courts for trial.

How long do MDL proceedings typically take?

MDL proceedings can last anywhere from 2-7 years depending on complexity, number of cases, and settlement negotiations. Most cases settle during the MDL phase rather than proceeding to individual trials.

Can I opt out of an MDL if my case is transferred?

You cannot opt out of MDL transfer since it only consolidates pretrial proceedings, but you retain all rights to your individual case and can request remand to your original court for trial if no settlement is reached.

Who pays for the costs of MDL proceedings?

Common costs are typically shared among plaintiff attorneys through court-ordered assessments, while individual attorneys remain responsible for their own case-specific expenses and client representation costs.

What happens if I disagree with an MDL settlement?

You can object to proposed settlements, and your individual attorney can advocate for your specific circumstances. If you reject a settlement, your case may be remanded to the original court for individual litigation.
