Sec. 103.2 Applications, petitions, and other documents.
(b) Evidence and processing.
(16) Inspection of evidence. An applicant or petitioner shall be permitted to inspect the record of proceeding which constitutes the basis for the decision, except as provided in the following paragraphs.
(i) Derogatory information unknown to petitioner or applicant. If the decision will be adverse to the applicant or petitioner and is based on derogatory information considered by the Service and of which the applicant or petitioner is unaware, he/she shall be advised of this fact and offered an opportunity to rebut the information and present information in his/her own behalf before the decision is rendered, except as provided in paragraphs (b)(16)(ii), (iii), and (iv) of this section. Any explanation, rebuttal, or information presented by or in behalf of the applicant or petitioner shall be included in the record of proceeding.
(ii) Determination of statutory eligibility. A determination of statutory eligibility shall be based only on information contained in the record of proceeding which is disclosed to the applicant or petitioner, except as provided in paragraph (b)(16)(iv) of this section.
(iii) Discretionary determination. Where an application may be granted or denied in the exercise of discretion, the decision to exercise discretion favorably or unfavorably may be based in whole or in part on classified information not contained in the record and not made available to the applicant, provided the regional commissioner has determined that such information is relevant and is classified under Executive Order No. 12356 (47 FR 14874; April 6, 1982) as requiring protection from unauthorized disclosure in the interest of national security.
(iv) Classified information. An applicant or petitioner shall not be provided any information contained in the record or outside the record which is classified under Executive Order No. 12356 (47 FR 14874; April 6, 1982) as requiring protection from unauthorized disclosure in the interest of national security, unless the classifying authority has agreed in writing to such disclosure. Whenever he/she believes he/she can do so consistently with safeguarding both the information and its source, the regional commissioner should direct that the applicant or petitioner be given notice of the general nature of the information and an opportunity to offer opposing evidence. The regional commissioner's authorization to use such classified information shall be made a part of the record. A decision based in whole or in part on such classified information shall state that the information is material to the decision.
