3M Combat Arms earplug litigation (2019-2023)
More than 250,000 veterans and service members sued 3M over defective earplugs that allegedly caused hearing loss. The cases were consolidated into a multidistrict litigation, and bellwether trials produced several large plaintiff verdicts.
3M faced mounting verdicts and pressure from the bellwether process.
3M agreed to pay $6 billion to resolve the litigation in 2023.
Shows how bellwether trials in a mass tort MDL can pressure a company into a global settlement.
