On August 25, 1993, the Seneca Nation commenced an action in the United States District Court for the Western District of New York to reclaim land that allegedly was taken from them without the approval of the United States. The Senecas argued the 1815 transaction with New York State violated the Trade and Intercourse Act of 1790, which stated that no Native American lands were to be sold without the federal government's consent. The Senecas sought the ejection of more than 2,000 property owners on the island. By decision and order dated June 21, 2002, the trial court held the subject lands were ceded to Great Britain in the 1764 treaties of peace and the subject lands were not owned by the Seneca at the time of the 1794 Treaty of Canandaigua. New York state's purchase of them in 1815 was intended to avoid conflict with the Senecas over land it already owned. This decision was appealed, and the United States Court of Appeals for the Second Circuit affirmed the trial court's decision on September 9, 2004. The Senecas then sought review of this decision by the Supreme Court of the United States, which was denied on June 5, 2006.
