(b) any tribunal, person or authority having power to hear appeals from, or to review, a decision with respect to the security clearance decision or security clearance suitability assessment;

(2) If the Administrative Review Tribunal has made findings upon a review of a security clearance decision, or security clearance suitability assessment, that is an externally reviewable decision, the Organisation must not make a further security clearance decision or security clearance suitability assessment in respect of the affected person that is not in accordance with those findings except on the basis of matters occurring after the review or of which evidence was not available at the time of the review.
