(a) Whenever an individual has not been afforded an opportunity to cross-examine witnesses who have furnished information adverse to the individual under the provisions of §§ 710.26(l) or (o), the Secretary may issue a final decision to deny or revoke access authorization for the individual after personally reviewing the administrative record and any additional material provided by the Chair. The Secretary's authority may, in accordance with applicable provisions of Executive Order 12968, be delegated to the Deputy Secretary where the effected individual is a Federal employee. The Secretary's authority, in accordance with applicable provisions of Executive Order 10865, may not be delegated where the effected individual is a contractor employee. This authority may be exercised only when the Secretary determines that the circumstances described in § 710.26(l) or (o) are present, and such determination shall be final and not subject to review or appeal.

(b) Whenever the Secretary issues a final decision as to an individual's access authorization eligibility, the individual and other concerned parties shall be notified in writing by the Chair of that decision and of the Secretary's findings with respect to each instance of derogatory information contained in the notification letter and each substantial issue identified in the statement in support of the request for review to the extent allowed by the national security.

(c) Nothing contained in these procedures shall be deemed to limit or affect the responsibility and powers of the Secretary to issue subpoenas or to deny or revoke access to classified matter or special nuclear material.
