Ladew v. Tennessee Copper Company, 218 U.S. 357 (1910), was a United States Supreme Court case involving jurisdiction over a suit involving a citizen from another state beyond the Court's jurisdiction, suing a New Jersey Corporation, another out of state citizen. The Court asserted that under the statute jurisdiction was improper because neither party was a citizen in the jurisdiction of the Circuit Court. The Court followed the decision in Wetmore v. Tennessee Copper Company another case decided later that same year.
