When deriving information from a properly marked source document, what should be applied to the Declassify On line of the new document?

When deriving information from a properly marked source document, it is essential to apply the same declassification information as present in the source document to the Declassify On line of the new document. This practice ensures that the new document remains compliant with the original classification guidance, maintaining the integrity of the classified information. By replicating the declassification date and any specific instructions from the source document, you help prevent unauthorized disclosure of sensitive information that may be applicable to both documents.

This approach reflects the principle of continuity in classification management, which reinforces accountability and clarity regarding the status of classified materials. Following this protocol allows anyone handling the new document to be aware of the same classification restrictions that apply to the original source, ensuring proper handling and safeguarding of potentially sensitive information.
