REMOVED IN BUSH VERSION: (c) If there is significant doubt about the appropriate level of classification, it shall be classified at the lower level.
REMOVED IN BUSH VERSION: (e) To the extent practicable, agencies shall adopt a system of records management that will facilitate the public release of documents at the time such documents are declassified pursuant to the provisions for automatic declassification in sections 1.6 and 3.4 of this order.
