The American Civil Liberties Union is reportedly set to appeal a judge's decision to throw out the lawsuit against the National Security Agency's alleged mass surveillance programmes.
The ACLU had filed a lawsuit against the federal government for not revealing the exact extent of its alleged collection of Americans' telephone data.
However, last week, Judge William Pauley III of the US District Court for the Southern District of New York ruled that the NSA's phone records program was legal and threw out the ACLU challenge, PC World reports.
The ACLU had charged the US intelligence agencies, the NSA, the CIA, the Department of Defense, the Department of Justice and the Department of State for failing to uphold several Freedom of Information Act requests for surveillance-tied documents.
The body's deputy legal director Jameel Jaffer said that the NSA's call-tracking program violates both statutory law and the Constitution, and they looked forward to making their case in the appeals court.
Pauley's decision stands in contract to the decision made by Judge Richard Leon of US District Court for the District of Columbia, who had called the programmes 'Orwellian' and questioned their very existence.
