The Electronic Frontier Foundation (EFF) filed a class-action lawsuit against AT&T on January 31, 2006, accusing the telecom giant of violating the law and the privacy of its customers by collaborating with the National Security Agency (NSA) in its massive, illegal program to wiretap and data-mine Americans' communications. In May, 2006, many other cases were filed against a variety of telecommunications companies. Subsequently the Multi-District Litigation Panel of the federal courts transferred approximately 40 cases to the Northern District of California federal court.

These six cases were brought by the federal government against various state administrators to terminate subpoenas seeking information from the telecoms about whether they violated state privacy laws as part of the the warrantless surveillance. The subpoenas were issued by the New Jersey Attorney General and the Public Utilities Commissioners of Vermont, Connecticut, Maine and Missouri.

This is the Court Order Granting the US's Motion for Summary Judgment in US v Clayton, US v Reishus, US v Farber, US v Palermino & US v Volz AND dismissing Clayton v AT&T with prejudice.
