Restricted Data
Restricted Data is a category of classified information established by the Atomic Energy Act of 1954 (and its predecessor, the Atomic Energy Act of 1946) covering nuclear weapons design, production processes, and special nuclear materials. It is the only classification in the United States that applies automatically to information by subject matter — without requiring a formal classification review, designation, or stamping — making it "born classified." This automatic application originated as an informal wartime practice by Leslie Groves during the Manhattan Project, where the scientific secrecy surrounding nuclear fission was treated as inherently secret regardless of formal designation.
Legal Basis and Distinction from Executive Order Classification
Standard US classified information (confidential, secret, top secret) operates under presidential executive orders — specifically iterations of orders dating to Eisenhower's EO 10501, Reagan's EO 12356, and Obama's EO 13526. These classifications can be modified or revoked by presidential executive order.
Restricted Data, by contrast, is established by statute: the Atomic Energy Act of Congress. This means:
- Restricted Data cannot be declassified by executive order; it requires specific congressional action or a formal DOE determination to remove the restricted data designation
- Information classified as Restricted Data is not subject to standard FOIA requests applicable to other federal records
- Restricted Data classification is administered by the Department of Energy (and its predecessor, the Atomic Energy Commission), not the DoD or executive branch classification system
- Restricted Data uses its own clearance system: Q clearance (equivalent to top secret) and L clearance (equivalent to secret), separate from DoD clearances
Related Category: Transclassified Foreign Nuclear Information (TFNI)
Section 142 of the Atomic Energy Act of 1954 created Transclassified Foreign Nuclear Information (TFNI) — a designation for information that was originally classified by a foreign government pertaining to nuclear programs and incorporated into US classified holdings. TFNI enjoys dual classification framework protection under both the Atomic Energy Act and executive order systems, and is explicitly exempt from declassification.
The Schumer UAP disclosure amendment (UAPDA) explicitly states that UFO legacy programs have misclassified UAP materials, data, files, programs, and discoveries as TFNI. This allows non-nuclear materials and programs to benefit from the most restrictive statutory classification framework in the US government.
"Special Nuclear Material" as a Classification Vehicle
Section 51 of the 1954 Act defines "special nuclear material" as anything that gives off a sizable amount of atomic energy — intentionally or functionally broad. David Grusch has noted this definition is vague enough to encompass recovered non-human materials exhibiting radiological properties, enabling their classification under DOE statutory authority: "They're basically treating this as nuclear secrets because it gives off nuclear radiation... what legal gymnastics are you saying this stuff is a US nuclear secret? You're transclassifying it into a nuclear secret."
Practical Significance for UAP Disclosure
Because Restricted Data and TFNI classifications are statutory rather than executive, a presidential executive order to release UFO-related files — regardless of the president issuing it — has no legal force over materials classified under these categories. This creates a structural barrier to UAP disclosure through executive action alone: materials protected under DOE's Restricted Data and TFNI designations exist in a separate legal universe from standard national security information and require either congressional action or a formal DOE declassification determination to release.
UAP Gerb identifies this dual-track classification system as a deliberate or fortuitously useful feature of the UFO legacy program security architecture: by classifying recovered non-human materials and programs under DOE statutory authority from the late 1940s onward, the program created a legal protection that has proven resistant to every subsequent attempt at executive-branch transparency.
