Whether FOIA Exemption 2 permits an agency to withhold explosives-safety maps and data that guide agency operations but do not concern employee relations or human resources.
Holding
No. Exemption 2 covers only records relating solely to an agency's internal personnel rules and practices—that is, employee-relations and human-resources matters—and does not cover the Navy's ESQD records.
Reasoning
The Court began with Exemption 2's text: records "related solely to the internal personnel rules and practices of an agency." In ordinary usage, "personnel" refers to human-resources subjects, including hiring, discipline, compensation, benefits, work rules, and employee relations. The word therefore limits the exemption to rules and practices about employees, rather than any internal matter used by employees.
FOIA's use of "personnel" in Exemption 6 reinforced that reading. There, "personnel and medical files" plainly means human-resources files. Reading the same term consistently in the nearby Exemption 2 supports treating "personnel rules and practices" as rules concerning conditions of federal employment.
The Court's earlier decision in Department of the Air Force v. Rose also supported this narrow understanding. Rose described matters such as parking, lunch hours, and sick leave, and explained that Exemption 2 principally relieves agencies from maintaining routine, internally significant employment information for public inspection.
The statutory purpose confirmed the textual reading. FOIA generally requires disclosure, and its exemptions must be narrowly construed. Congress replaced the broader APA exemption for matters relating solely to an agency's "internal management" because that language had enabled excessive withholding. A construction covering operational information far beyond human-resources matters would recreate the expansive withholding Congress sought to curb.
The requested ESQD materials did not concern workplace rules governing sailors or other employees. They described the physical effects of explosions and safe distances for explosives storage. Although those materials help Navy personnel perform their jobs, they are not, in ordinary language, personnel rules or practices.
