Whether the Government established, on the existing record, that the requested personnel-management evaluations and special studies were wholly exempt from disclosure under FOIA Exemptions 2, 5, or 6.
Holding
No. The Government's conclusory affidavit and the District Court's unexplained summary judgment did not satisfy the agency's statutory burden to prove that the records, or identifiable portions of them, were exempt.
Reasoning
FOIA begins from a rule of disclosure: agency records must be made available unless a specific statutory exemption applies. Because the exemptions restrict that broad disclosure rule, courts must construe them narrowly. In a judicial action to compel disclosure, the statute requires the court to decide the matter de novo, and it expressly places the burden of sustaining withholding on the agency.
The record did not establish the actual character or contents of the disputed reports. The Government's affidavit merely asserted that the documents fit three exemptions; it did not provide a meaningful description of the information withheld, explain why particular material qualified for an exemption, or show that nonexempt material could not be segregated and released. Vaughn could not effectively rebut these assertions because he had never seen the documents.
EPA v. Mink distinguished records whose undisputed character plainly places them within an exemption from records whose factual character remains disputed. This case fell in the latter category. The asserted exemptions might apply to some portions of the reports, but the record did not permit a conclusion that they applied to every portion of every report.
A document is not wholly exempt merely because it contains some exempt information. The agency must account for reasonably segregable nonexempt material. The District Court's bare grant of summary judgment gave the court of appeals no way to tell whether the trial judge had considered partial disclosure or had instead accepted the Government's blanket claim that all materials were exempt.
