The Right to Information Act, 2005 overrides the Official Secrets Act, 1923, and no information can be denied solely on grounds of being classified under OSA.

RTI Act, Section 8(1): Lists exemptions including information which would prejudicially affect: (a) Sovereignty/integrity of India, (b) Security, strategic, scientific, economic interests of State, (c) Relation with foreign State, (d) Incitement to offence. Such information may be denied even if not explicitly covered by OSA. However, Section 8(2): Even exempt information must be disclosed if public interest in disclosure outweighs harm. Balances transparency with legitimate security concerns; courts decide on case-by-case basis.
