Final answer:
A derivative classifier who believes information is improperly classified has the option to challenge the classification decision, initiating a review process.
Step-by-step explanation:
If a derivative classifier believes information to be improperly classified, they can challenge the classification decision.
The process allows individuals with proper clearance and access to question the appropriateness of classification decisions without necessarily having the authority to overrule or appeal. Instead, challenging the decision initiates a review procedure by which the classification can be reassessed.
A derivative classifier isn't empowered to overrule any act of Congress they don't like or to defer to the decisions of the elected branches of government; nor is it within their purview to make mostly liberal rulings. The act of challenging is meant to ensure that information is classified properly according to national security guidelines.
