14 CFR 1203.401: Effect of open publication.

Public disclosure, regardless of source or form, of information currently classified or being considered for classification does not preclude initial or continued classification. However, such disclosure requires an immediate reevaluation to determine whether the information has been compromised to the extent that downgrading or declassification is indicated. Similar consideration must be given to related items of information in all programs, projects, or items incorporating or pertaining to the compromised items of information. In these cases, if a release were made or authorized by an official Government source, classification of clearly identified items may no longer be warranted. Questions as to the propriety of continued classification should be referred to the Chairperson, NASA Information Security Program Committee.
