On January 17, 2006, the American Civil Liberties Union (ACLU) on its own behalf, and on the behalf of three other organizations and five individuals, sued the National Security Agency (NSA) in the United States District Court for the Eastern District of Michigan, seeking declaratory judgment and injunctive relief arguing the TSP was unconstitutional and a violation of federal law. The government argued that the lawsuit should be dismissed or alternatively be granted summary judgment based on the State Secrets Privilege and the plaintiffs' lack of standing.
