The 9 Exemptions to a FOIA Request

The Freedom of Information Act establishes a broad right of public access to federal agency records, but it is not absolute. Congress recognized that certain categories of information must remain protected in order to preserve national security, personal privacy, and the proper functioning of government. To address this, FOIA includes nine specific exemptions that allow, but do not require, agencies to withhold documents or portions of documents from disclosure. Understanding these exemptions is essential for anyone submitting FOIA requests or challenging agency withholding decisions.

It is important to note that these exemptions are permissive, not mandatory. An agency may choose to release information even when an exemption technically applies, particularly under the modern presumption of openness standard. Additionally, even when an exemption applies to part of a document, the agency must release all reasonably segregable non-exempt portions.

Exemption 1 - Classified National Security Information

Exemption 1 protects records that are properly classified under executive orders governing national security. This includes information related to intelligence sources and methods, defense plans, foreign government information, and other material whose release could reasonably be expected to cause damage to national security. To be withheld under this exemption, information must have been classified by an authorized agency official according to established procedures.

Courts apply meaningful judicial review to national security withholdings, meaning agencies cannot simply claim national security as a blanket justification for withholding records. They must demonstrate that proper classification procedures were followed.

Exemption 2 - Internal Agency Rules and Practices

Exemption 2 covers records related solely to the internal personnel rules and practices of an agency. Originally, courts interpreted this exemption broadly, but the Supreme Court’s 2011 decision in Milner v. Department of the Navy significantly narrowed its scope. Today, Exemption 2 is limited to information about human resources matters such as personnel rules and internal management practices, it no longer covers information that would help circumvent agency law enforcement procedures.

Exemption 3 - Information Withheld by Other Statutes

Exemption 3 applies when another federal statute specifically authorizes withholding certain information, either because it requires that the information be withheld without agency discretion, or because the statute establishes particular criteria for withholding. There are hundreds of federal statutes that qualify under Exemption 3, covering areas such as tax return information, trade secrets submitted to regulatory agencies, certain census data, and national intelligence sources and methods. The CIA Information Act and certain provisions of the Intelligence Community Reform Act are examples of Exemption 3 statutes.

Exemption 4 - Trade Secrets and Commercial Information

Exemption 4 protects trade secrets and commercial or financial information that is both privileged and confidential and was obtained from a person or company outside of the government. This exemption is commonly invoked to protect proprietary business information submitted to regulatory agencies, for example, pharmaceutical companies’ drug applications to the FDA, or contractors’ pricing information submitted to procurement offices.

The Supreme Court’s 2019 decision in Food Marketing Institute v. Argus Leader Media significantly strengthened Exemption 4, holding that information is ‘confidential’ under this exemption if the information provider customarily kept it private and provided it to the government under an assurance of privacy.

Exemption 5 - Inter-Agency and Intra-Agency Deliberative Materials

Exemption 5 protects internal government communications that would not be available to a party in litigation against the agency. This exemption incorporates several common-law privileges, most notably the deliberative process privilege, which protects predecisional, deliberative communications, draft documents, recommendations, and internal debates that reflect the give-and-take of the decision-making process. It also encompasses the attorney-client privilege and attorney work-product protection.

Importantly, the FOIA Improvement Act of 2016 introduced a 25-year sunset on Exemption 5 withholdings: agencies may not invoke the deliberative process privilege to withhold records that are more than 25 years old. This provision ensures that historical deliberative records eventually become accessible to the public.

Exemption 6 - Personal Privacy

Exemption 6 protects information in personnel and medical files, and similar files, whose disclosure would constitute a clearly unwarranted invasion of personal privacy. When evaluating Exemption 6 withholdings, agencies and courts must balance the individual’s privacy interest against the public interest in disclosure. The fact that information is embarrassing or merely private is not enough, the privacy interest must clearly outweigh any public benefit from disclosure.

Exemption 7 - Law Enforcement Records

Exemption 7 protects records or information compiled for law enforcement purposes, but only when disclosure could cause specific harms. There are six subcategories of harm covered: records that could interfere with enforcement proceedings, deprive someone of a fair trial, constitute an unwarranted invasion of personal privacy, disclose the identity of a confidential source, disclose law enforcement techniques and procedures, or endanger the life or physical safety of any individual. This is one of the most commonly invoked exemptions by federal law enforcement agencies such as the FBI, DEA, and ATF.

Exemption 8 - Financial Institution Records

Exemption 8 protects records prepared by, on behalf of, or for the use of an agency responsible for the regulation or supervision of financial institutions. This covers documents related to bank examinations, compliance reviews, and supervisory assessments conducted by agencies like the Federal Reserve, the FDIC, the OCC, and similar regulators. The rationale is that public disclosure of sensitive examination findings could destabilize financial institutions and undermine confidence in the banking system.

Exemption 9 - Geological and Geophysical Information

Exemption 9 is the narrowest and least commonly invoked of all nine exemptions. It protects geological and geophysical information and data, including maps, concerning wells. This exemption is primarily intended to protect the commercial interests of oil and gas companies that submit sensitive well data to federal regulators such as the Bureau of Land Management or the Department of the Interior. Its narrow scope means it rarely comes into play in everyday FOIA practice.

What Happens When an Exemption Is Applied

When an agency withholds records under one or more exemptions, it must tell you which exemption(s) apply. Agencies often provide a ‘Vaughn index’, a detailed document-by-document breakdown of withheld material and the specific exemptions claimed, particularly in FOIA litigation. You have the right to appeal withholding decisions administratively and, ultimately, to challenge them in federal court.

Even when an exemption applies, agencies are required to release all reasonably segregable portions of a document. This means they must redact only the protected information and release everything else, rather than withholding entire documents simply because they contain some exempt material.

Conclusion

The nine FOIA exemptions represent a carefully calibrated balance between transparency and the legitimate need to protect sensitive information. Understanding how each exemption works, and knowing that exemptions are permissive, not mandatory, empowers requesters to push back against over-broad withholdings and advocate for the disclosure of as much information as possible. When an agency invokes an exemption, it is not necessarily the end of the road: appeals, litigation, and negotiation are all available tools for obtaining the records you need.
