exclusive, bills—the Terrorist Surveillance Act of 2006 (S.2455), the National Security Surveillance Act of 2006 (S.2455) and the Foreign Intelligence Surveillance Improvement and Enhancement Act of 2006 (S.3001) – were referred for debate to the full Senate, but did not pass. Each of these bills would have broadened the statutory authorization for electronic surveillance, while subjecting it to some restrictions. Termination On January 17, 2007, Gonzales informed Senate leaders that the program would not be reauthorized. "Any electronic surveillance that was occurring as part of the Terrorist Surveillance Program will now be conducted subject to the approval of the Foreign Intelligence Surveillance Court," according to his letter. Further legal action The American Civil Liberties Union (ACLU) sued NSA over the program. Detroit District Court judge Anna Diggs Taylor ruled on August 17, 2006 that the program was illegal under FISA as well as unconstitutional under the First and Fourth amendments of the Constitution. Judicial Watch, a watchdog group, discovered that at the time of the ruling Taylor "serves as a secretary and trustee for a foundation that donated funds to the ACLU of Michigan, a plaintiff in the case". ACLU v. NSA was dismissed on January 31, 2007 by the United States Court of Appeals for the Sixth Circuit. The court did not rule on the spying program's legality. Instead, it declared that the plaintiffs did not have standing to sue because they could not demonstrate that they had been direct targets of the program. The Supreme Court let the ruling stand. On August 17, 2007, FISC said it would consider a request by the ACLU that asked the court to make public its recent, classified rulings on the scope of the government's wiretapping powers. FISC presiding judge Colleen Kollar-Kotelly signed an order calling the ACLU's motion "an unprecedented request that warrants further briefing". The FISC ordered the government to respond on the issue by August 31. On the August 31 deadline, the National Security Division of the Justice Department filed a response in opposition to the ACLU's motion. On February 19, 2008, the U.S. Supreme Court, without comment, turned down an ACLU appeal, letting stand the earlier decision dismissing the case. On September 18, 2008, the Electronic Frontier Foundation (EFF) sued the NSA, President Bush, Vice President Cheney, Cheney's chief of staff David Addington, Gonzales and other government agencies and individuals who ordered or participated in the program.
