A mass tort is a civil action that involves multiple claimants who have been harmed by the same defendant or group of defendants. Mass torts are an efficient way for multiple plaintiffs to have their voices heard against a common and often powerful defendant. Defendants are often large corporations, multinational pharmaceutical companies, product manufacturers, or medical facilities and practitioners. In filing a mass tort, the nature and extent of a claimant’s injuries or illnesses are major determining factors in setting the claim’s value. A victim’s diagnosis legitimizes the claim. If you believe you meet the criteria for a mass tort lawsuit, it is essential to be examined and treated by a medical provider as soon as possible.
