On October 26, 2006, President George W. Bush signed the Secure Fence Act of 2006 [PDF], authorizing the construction of a 700-mile fence on the US-Mexico border, despite opposition from Mexican President Vicente Fox. President Bush claimed that the construction of the fence was necessary to the enforcement of existing federal immigration regulations. However, the fence's construction faced legal opposition from landowners along the border, who argued that the use of legal waivers by Secretary of the Department of Homeland Security Michael Chertoff to expedite construction of the fence violated their constitutional rights. That lawsuit was dismissed by the US District Court for the District of Columbia for lack of standing, and the Supreme Court declined to hear the appeal in June 2009.
