A mass tort is a civil action involving numerous plaintiffs against one or a few corporate defendants. The tort may involve, for example, personal injuries suffered by numerous plaintiffs as a result of a defective product, or a mass disaster in which there were many injured persons, such as an airplane crash, or exposure of a large group of people to toxic chemicals or pharmaceuticals.
Riverton is a city in Fremont County, Wyoming, United States. It is both the largest city in the county and the largest within the historical boundaries of the Wind River Indian Reservation. The city's population was 9,310 at the 2000 census. The city is an incorporated entity of the state of Wyoming, on land ceded from the reservation in 1906, a situation that often makes it subject to jurisdictional claims by the nearby Eastern Shoshone and Northern Arapaho tribes.
