National Security Law Research Guide

This guide covers U.S. military, espionage, homeland security, and classification/declassification law.

Classification & Declassification of Government Documents

For the most part, individual federal agencies decide whether to classify or declassify information they create.  They do so on the basis of Exec. Order No. 13,526, 75 Fed. Reg. 707 (Dec. 29, 2009) and guidance issued by the Information Security Oversight Office of the National Archives and Records Administration (ISOO).  Appeals of classification decisions are decided by the Interagency Security Classification Appeals Panel.
