That seems to be recent thing (over the last decade or 2) with the US. The Supreme Court of India recently made these observations when the government refused to share certain information with it under the bogey of "national security": > "... In a democratic country governed by the rule of law, indiscriminate spying on individuals cannot be allowed except with sufficient statutory safeguards, by following the procedure established by law under the Constitution ... > We had made it clear to the learned Solicitor General on many occasions that we would not push the Respondent-Union of India to provide any information that may affect the national security concerns of the country. However, despite the repeated assurances and opportunities given, ultimately the Respondent-Union of India has placed on record what they call a "limited affidavit", which does not shed any light on their stand or provide any clarity as to the facts of the matter at hand. > However, this does not mean that the State gets a free pass every time the spectre of "national security" is raised. National security cannot be the bugbear that the judiciary shies away from, by virtue of its mere mentioning. Although this Court should be circumspect in encroaching the domain of national security, no omnibus prohibition can be called for against judicial review. > The Respondent-Union of India must necessarily plead and prove the facts which indicate that the information sought must be kept secret as their divulgence would affect national security concerns. They must justify the stand that they take before a Court. The mere invocation of national security by the State does not render the Court a mute spectator" > ... We are not interested in knowing matters related to security or defence. We are only concerned to know whether Govt has used any method other than admissible under law ..."
