Wetmore v. Tennessee Copper Company, 218 U.S. 369 (1910), was a United States Supreme Court case involving jurisdiction over a suit involving a wealthy landowner from Rhode Island, U.S. Senator George P. Wetmore, suing a New Jersey Corporation for emitting toxic fumes onto land he owned in Tennessee. The Court followed its precedent in Ladew v. Tennessee Copper Company,[1] in asserting that jurisdiction was improper because neither party was a citizen in the jurisdiction of the Circuit court, but jurisdiction was proper over the foreign British corporation that was joined to the suit.[2]
