C4.6.1. Purpose and Authority. Downgrading of
information to a lower level of classification is appropriate when the
information no longer requires protection at the originally assigned level,
and can be properly protected at a lower level. The principal purpose of
downgrading is to conserve security resources by avoiding protection of
information at too high a level. Information may be downgraded by any
official who is authorized to classify or declassify the information. (See
paragraph C4.1.3., above.)
C4.6.2. Downgrading Decisions During Original Classification.
Downgrading should be considered when original classifiers are deciding on
the duration of classification to be assigned. If downgrading dates or
events can be identified, they must be specified along with the
declassification instruction. Note that downgrading instructions DO NOT
replace declassification instructions.
C4.6.3. Downgrading at a Later Date. Information may be
downgraded by any official who is authorized to classify or declassify the
information. (See paragraph C4.1.3.,
above.) The authorized official making the downgrading decision shall notify
holders of the change in classification.
