An MDL can bring related federal lawsuits before one judge for shared pretrial work. It does not turn them into one case or decide who wins.

Rules & Procedures
The governing statute and current Panel rules.
One court handles the shared pretrial work
Multidistrict litigation, usually shortened to MDL, is a federal procedure for civil lawsuits pending in different districts that share factual questions. The Judicial Panel on Multidistrict Litigation can transfer those actions to one federal district for coordinated or consolidated pretrial proceedings.
The Panel chooses the district and the judge or judges who will handle that shared work. The Panel says centralization is meant to reduce duplicated discovery, avoid inconsistent pretrial rulings and conserve the resources of the parties and the courts.
What changes after transfer
Instead of repeating the same pretrial disputes in several courts, the transferred cases can move through common discovery and coordinated pretrial decisions before the transferee court. The details come from the orders entered in that particular MDL; the statute does not create one universal schedule.
A transfer is not a ruling that the plaintiffs are right, that a product caused an injury, or that anyone will receive money. It creates a shared pretrial structure and nothing more by itself.
How cases leave the MDL
Some actions may end while they are in the transferee district. Actions that are not terminated there are remanded by the Panel to the districts where they began at or before the end of the centralized pretrial proceedings.
To understand a specific case, look for its transfer order, the MDL docket, case-management orders and any later remand order. Those records show what has actually happened; the MDL label alone does not.
