What is the difference between a class action lawsuit and a mass tort litigation?

A class action lawsuit involves a group of plaintiffs with similar claims against a defendant, treated as a single entity, where one or a few representatives act on behalf of the entire group. In contrast, mass tort litigation allows each plaintiff to maintain their individual lawsuit, providing personalized attention to each case while still benefiting from collective pretrial proceedings for efficiency. This individualized approach in mass torts often results in more tailored compensation and outcomes for the plaintiffs.
