How long does the deliberative process privilege under FOIA Exemption 5 last, and does it expire?

The deliberative process privilege under FOIA Exemption 5 protects pre-decisional, deliberative records — drafts, recommendations, and internal opinions that reflect an agency’s give-and-take before it reaches a final decision. Unlike a fixed retention clock, this privilege does not run for a set number of years from when a record is created. Instead, whether it still applies depends on the record itself and, importantly, on how much time has passed.

Does it expire?

Yes — in a meaningful sense, it does. The FOIA Improvement Act of 2016 added a hard outer limit: an agency may no longer withhold records solely under the deliberative process privilege once the records are more than 25 years old. After that point, the deliberative process basis for Exemption 5 simply is no longer available, even if the material is still pre-decisional in character.

Before reaching that 25-year mark, the privilege can still erode. Two things commonly remove it:

• The record loses its pre-decisional status once the agency adopts or expressly incorporates it into a final decision.
• The privilege weakens as records age and the deliberation they reflect becomes historical rather than active.

Foreseeable harm still applies

Even when the privilege technically fits, agencies cannot withhold automatically. Under current law, an agency must reasonably foresee that disclosure would harm an interest the exemption protects (or that disclosure is prohibited by law). If releasing an old draft would cause no real harm to candid deliberation, the agency should release it.

What this means for requesters

• Age matters. If material is decades old, ask whether the deliberative basis still holds.
• Final decisions are generally not shielded by this privilege, only the deliberation leading up to them.
• Other Exemption 5 privileges (such as attorney-client or attorney work-product) have their own rules and are not subject to the 25-year limit.

A note on scope: this answer addresses the federal FOIA. State public-records laws have their own deliberative or “executive” privileges, and the rules, time limits, and exceptions vary widely by state.
