Class actions are lawsuits brought by a representative member(s) of a large group of persons on behalf of all the members of the group who have suffered identical or similar harm for which the same defendant may be liable -- such as a defective product class action against a manufacturer or an employment discrimination class action against a large company.
Picher was a city in Ottawa County, Oklahoma, United States. It was formerly a center of lead and zinc mining. The population was 1,640 at the 2000 census. Discoveries of ground contamination and the possibility of a cave-in of mines under the city have prompted all of its population to evacuate, and the nearby town of Cardin is following suit. The town is within the boundaries of the Tar Creek Superfund site.
