5 U.S.C. § 552(b)(3) states that information specifically exempted from disclosure by statute (other than section 552b of this title), provided that such statute (A) requires that the matters be withheld from the public in such a manner as to leave no discretion on issue or (B) establishes particular criteria for withholding or refers to particular types of matters to be withheld.
What it means: Information that is prohibited from disclosure by another federal law.
There is another law prohibiting disclosure. The Department of Justice has compiled a non-comprehensive list of relevant laws used in this context, and ProPublica has a searchable database of b3-cited laws.
