What determines whether information retains its classified status upon declassification review?

The primary factor that determines whether information retains its classified status during a declassification review is the potential risks to national security. This involves evaluating whether the disclosure of the information could reasonably be expected to cause damage to national security interests. If the review concludes that releasing the information poses such a risk, it may remain classified despite any changes in context or the passage of time.

Other factors, while relevant, do not solely dictate the outcome of a declassification review. The original classification authority refers to the individual who initially classified the information, but their initial decision does not automatically dictate its status upon review. Current classification guidelines inform the review process but are not the determining factor. Similarly, the timeframe of the original classification may provide context, but the crux of the decision is based on assessing potential risks to national security at the time of the review.
