Multidistrict litigation (MDL) is a legal process that consolidates multiple related cases into one court to streamline proceedings. This typically occurs when numerous lawsuits involve similar issues, such as product liability or mass torts, allowing for more efficient handling of evidence and discovery. In an MDL, a single judge oversees the pretrial phase, which can include motions, discovery, and settlement discussions. Once the pretrial matters are resolved, cases may be sent back to their original courts for trial, ensuring that each plaintiff still has their day in court while benefiting from the efficiencies of consolidation.
