I love it when I learn something on DP. Thank you!
Exemptions
The nine exemption categories that authorize government agencies to withhold information are:
classified information for national defense or foreign policy
internal personnel rules and practices
information that is exempt under other laws
trade secrets and confidential business information
inter-agency or intra-agency memoranda or letters that are protected by legal privileges
personnel and medical files
law enforcement records or information
information concerning bank supervision
geological and geophysical information
Exclusions
Congress provided special protection in the FOIA for three narrow categories of law enforcement and national security records. The provisions protecting those records are known as “exclusions”. The first exclusion protects the existence of an ongoing criminal law enforcement investigation when the subject of the investigation is unaware that it is pending and disclosure could reasonably be expected to interfere with enforcement proceedings. The second exclusion is limited to criminal law enforcement agencies and protects the existence of informant records when the informant’s status has not been officially confirmed. The third exclusion is limited to the FBI and protects the existence of foreign intelligence or counterintelligence, or international terrorism records when the existence of such records is classified. Records falling within exclusion are not subject to the requirements of the FOIA.
Please Note
The FOIA applies only to federal agencies and
does not create a right of access to records held by Congress, the courts, or by state or local government agencies.
The FOIA does not require agencies to do research for you, answer written questions, or in any other way create records (such as lists or statistics) in order to respond to a request.
