32 C.F.R. § 723.9
After final adjudication, further consideration will be granted only upon presentation by the applicant of new and material evidence or other matter not previously considered by the Board. New evidence is defined as evidence not previously considered by the Board and not reasonably available to the applicant at the time of the previous application. Evidence is material if it is likely to have a substantial effect on the outcome. All requests for further consideration will be initially screened by the Executive Director of the Board to determine whether new and material evidence or other matter (including, but not limited to, any factual allegations or arguments why the relief should be granted) has been submitted by the applicant. If such evidence or other matter has been submitted, the request shall be forwarded to the Board for a decision. If no such evidence or other matter has been submitted, the applicant will be informed that his/her request was not considered by the Board because it did not contain new and material evidence or other matter.
