Exemption One - National Security
Agency records which "reasonably could be expected to cause damage to the national security" if disclosed and are properly classified, are exempt. This kind of data usually includes -
Exemption Two - Internal Agency Rules
Information related solely to the internal personnel rules and practices of the agency. This is not usually of great interest to the general public, but in some instances the courts have ruled it is of interest to the general public, and has ordered its release. Examples of this have included Air Force handling of honor code violations, and training manuals for Occupational Safety and Health Administration compliance officers.
Exemption Three - Governed By Other Statutes
Information that is specifically exempted from disclosure by another statute. Laws have been passed making personal tax data, CIA structure, charges of employment discrimination, identifiable census data and other types of information confidential. The agency ought to specify which statute they are referring to when they give this reason for denying a FOIA request.
