Present and former law review editors who were researching disciplinary systems and procedures at the military service academies for an article were denied access to case summaries of honor and ethics hearings, with personal references or other identifying information deleted, maintained in the United States Air Force Academy's Honor and Ethics Code reading files. It was the Academy's practice to post copies of such summaries on forty squadron bulletin boards throughout the Academy and to distribute copies to Academy faculty and administration officials. The editors brought an action under the Freedom of Information Act (FOIA) against the Department of the Air Force to compel disclosure of the case summaries. Which exemptions to FOIA are most applicable? Explain whether any of these exemptions would enable the Academy to withhold the requested case summaries.
