De novo review by Special Counsel. After receipt of a timely appeal, the Special Counsel shall contact the relevant NCUA program office and request a complete set of all pertinent materials, including internal memoranda, correspondence, and records having a bearing on the initial agency determination being appealed. The Special Counsel will conduct an independent review of these materials, along with all materials submitted by the petitioner in support of the appeal. The Special Counsel will make a recommendation to the Board as to the appropriate disposition of the appeal after having evaluated the applicable legal arguments and considered the facts and circumstances that pertain to the appeal. As directed by the Board, the Special Counsel may provide his or her recommendation in writing to the Board and may make an oral presentation before the Board.

Determination on appeal. Within 90 calendar days from the date of receipt of an appeal by the Secretary of the Board, or within any extension of time as established by the Chairman, the Board shall issue a decision allowing, in whole or in part, or disallowing the petitioner's appeal. The decision by the Board shall be in writing, stating the reasons for the decision, and shall constitute a final agency action for purposes of chapter 7 of title 5 of the United States Code. Failure by the Board to issue a decision on an appeal within the 90-day period or within any extension of time as established by the Chairman shall be deemed to be a denial of the appeal.

Extension of time. In the discretion of the Chairman, the time frame for the Board's decision may be extended as the Chairman may consider necessary or appropriate for a full and fair consideration of the issues. For purposes of this paragraph (c), the Special Counsel is authorized to act on behalf of the Chairman and may, in that capacity, grant an extension of time.
