For mass tort plaintiffs, seeking relief in St. Louis, Missouri may soon no longer be a viable option. The Missouri Senate passed a bill effectively prohibiting the joinder of out-of-state plaintiffs, unless the joining plaintiff resides in an adjoining, less populated, county. Proponents of the law explain that of the 13,000 plus mass tort plaintiffs in the St. Louis court, barely a thousand are actually Missouri residents, and less than a quarter of those residents live in St. Louis.
