What is the test for a court to determine who should be given access to classified information?

Predictive judgment of this kind must be made by those with the necessary expertise.... [T]he protection of classified information must be committed to the broad discretion of the agency responsible, and this must include broad discretion to determine who may have access to it.... [C]ourts traditionally have been reluctant to intrude upon the authority of the Executive in military and national security affairs.
