FOIA Exemptions
The nine statutory categories under the Freedom of Information Act that permit a federal agency to withhold otherwise disclosable records, covering areas such as classified national security information, internal personnel matters, trade secrets, privileged inter-agency communications, and personal privacy.
FOIA establishes a strong presumption of disclosure for federal agency records, but Congress balanced that presumption against legitimate government and privacy interests through nine specific exemptions. An agency withholding a record under FOIA must identify the specific exemption relied upon and generally bears the burden of justifying the withholding if challenged.
The exemptions cover a range of interests: properly classified national security information, purely internal agency personnel rules, information exempted by another statute, confidential commercial or financial information, privileged inter- and intra-agency communications (including the deliberative process and attorney-client privileges), personal privacy in personnel and medical files, records compiled for law enforcement purposes that would cause specified harms if disclosed, records concerning regulated financial institutions, and geological data. Even where an exemption applies to part of a record, the agency must still disclose any reasonably segregable non-exempt portions rather than withholding the entire document.
A Juricratic simulation of a FOIA dispute can model each claimed exemption as an independent dial affecting only the specific withheld material it covers, letting a user see how a matter's outcome distribution shifts when an agency's exemption claims are strong across the board versus concentrated in a few disputed, high-value records.
How it actually shows up
Counsel litigating a FOIA denial evaluates each claimed exemption independently against the specific withheld material, presses for segregability of any non-exempt portions, and frequently uses the agency's own itemized description of withheld records to test whether the claimed exemption genuinely applies to each item rather than accepting a blanket withholding justification.
- Who has the burden of justifying a FOIA withholding?
- The agency generally bears the burden of demonstrating that a claimed exemption applies to the specific withheld material, rather than the requester having to disprove the exemption.
- If part of a document is exempt, does the whole document get withheld?
- Generally no. The agency must disclose any reasonably segregable non-exempt portions of a record, even when part of it is properly withheld under an exemption.
- Are FOIA exemptions mandatory or discretionary?
- Most FOIA exemptions are discretionary, meaning an agency may choose to disclose material that an exemption would otherwise permit it to withhold, subject to any separate statutory or policy constraints.

Juricratic is a simulation engine: every probability-like figure is a dial you set, not a calibrated prediction. Verify every rule, deadline, and figure against the authorities and orders that govern your matter.

Juricratic makes every one of these ideas a live dial: model your case as a solvable game, then watch the optimal line and the settlement window move as the assumptions do.
