A mass tort is a legal action where many individuals come together to sue a defendant, usually a corporation, for similar injuries or damages caused by the same product or action. This type of lawsuit allows multiple claimants to consolidate their cases, making the legal process more efficient and cost-effective. Mass torts often arise from issues like defective products, environmental disasters, or harmful pharmaceuticals. In these cases, the plaintiffs seek compensation for their injuries, and the outcome can lead to significant financial penalties for the responsible party, as well as changes in practices to prevent future harm.
