Plaintiffs have won a rare victory against the government in a case involving the state secrets privilege. On April 1, 2010, Federal District Judge Vaughn Walker ruled in favor of Al-Haramain Islamic Foundation, Inc., a now-defunct Islamic charity that had sued the government for intercepting its employees' international telephone conversations without obtaining a warrant. Al-Haramain claimed the government's warrantless wiretap violated the Foreign Intelligence Surveillance Act (FISA), a federal law that limits the government's ability to eavesdrop on its citizens. The case is one of several challenging the National Security Agency's warrantless wiretapping program. The government has responded to all such lawsuits by arguing because its surveillance activities concern national security, the state secrets privilege requires dismissal of claims that it violated FISA.
Yet FISA was enacted for the very purpose of preventing the government from eavesdropping without a warrant, and it provides a mechanism by which individuals or groups who believe they have been victims of an unlawful government wiretap can seek redress in the courts even when the claim relies on classified evidence. Under FISA, if a plaintiff establishes a "colorable basis" for believing that it has been subject to unlawful surveillance, the Court can then examine classified evidence in camera to determine whether the surveillance occurred, and if so whether it was lawful.

On Tuesday, the Supreme Court heard
A national security letter is a simple form document issued by the FBI and other agencies of the government to obtain telephone call records, email to/from information, and other records about communications, as well as financial, credit, and other records, without any prior judicial authorization. NSLs are served on the business entities that hold the records and the businesses that receive NSLs must comply or challenge them in court, and with limited exceptions, are barred from disclosing to anyone that they have received or complied with the demand for records.
