documents. Implying such a waiver could tend to inhibit agencies from making any disclosures other than those explicitly required by law because voluntary release of documents exempt from disclosure requirements would expose other documents in the litigation to risk of disclosure. An agency would have an incentive to refuse to release all exempt documents if it wished to retain an exemption for any documents. Although the language of subsection (b) explicitly exempts documents in the covered categories from FOIA disclosure requirements, readily finding waiver of confidentiality for exempt documents would tend to thwart the underlying statutory purpose, which is to implement a policy of broad disclosure of government records. Cf. Chrysler Corp., 441 U.S. at 290-94, 99 S.Ct. at 1711-14 (<HOLDING>). In addition, the policy underlying FOIA
holding that ajny asserted right by third parties to prohibit disclosure must have a basis independent of the foia holding that the only relevant public interest in disclosure is the extent to which disclosure would serve the core purpose of the foia which is contributing significantly to public understanding of the operations or activities of the government  holding that foia exemptions are not mandatory bars to disclosure because the purpose of foia is to provide broad disclosure of government documents holding that the government must provide the party seeking disclosure with a detailed index describing the documents the government claims are exempt from disclosure under foia holding that unauthorized disclosure of documents does not constitute a waiver of the applicable foia exemption
