Judicial Panel on Multidistrict Litigation

Judicial Panel on Multidistrict Litigation

The JPML consists of seven circuit and district judges appointed by the Chief Justice. It decides motions for centralization, selects the transferee district and judge, and issues conditional transfer orders for later-filed related actions.

The Panel hears argument at sessions held several times per year.

JPML, The Panel

Why it Matters?

The Panel's selection of the transferee judge is the single most consequential decision in a mass tort's trajectory, because judges differ substantially in how they manage bellwether selection, Lone Pine orders, and settlement pressure. Both sides advocate for districts based on the assigned judge's history rather than convenience factors, and briefing addresses those preferences indirectly through arguments about docket conditions and experience.
