Is it permissible to use a personal identifier in the classification authority block of a newly declassified document if the identity of the declassification authority is classified?

Using a personal identifier in the classification authority block of a newly declassified document can be permissible under specific circumstances, particularly when the identity of the declassification authority is classified. This practice serves a few key purposes.

Firstly, including an identifier helps maintain a clear record of who authorized the declassification without revealing sensitive details about their identity. This aligns with the principles of transparency and accountability, as it allows for tracking and referencing declassification actions while keeping classified information secure.

Additionally, such a measure can prevent potential breaches of protocol or security by establishing a documented link to the authority under which the declassification occurred, thus allowing proper oversight without compromising any classified information. This approach emphasizes the importance of protecting sensitive identities in the classification process while still adhering to regulations about documentation and accountability.

It's important to note that in scenarios where there are specific conditions or restrictions governing the use of identifiers, those must be adhered to, hence why not all situations might outright support this. However, the necessity for declassification processes to have traceable authority makes it acceptable in certain contexts where the authority's identity remains protected.
