Pub. L. 90-351, tit. I, pt. E, sec. 510

Sec. 510. (a) In carrying out the functions vested by this title in the Administration, the determination, findings, and conclusions of the Administration shall be final and conclusive upon all applicants, except as hereafter provided. (b) If the application has been rejected or an applicant has been denied a grant or has had a grant, or any portion of a grant, discontinued, or has been given a grant in a lesser amount than such applicant believes appropriate under the provisions of this title, the Administration shall notify the applicant or grantee of its action and set forth the reason for the action taken. Whenever an applicant or grantee requests a hearing on action taken by the Administration on an application or a grant the Administration, or any authorized officer thereof, is authorized and directed to hold such hearings or investigations at such times and places as the Administration deems necessary, following appropriate and adequate notice to such applicant; and the findings of fact and determinations made by the Administration with respect thereto shall be final and conclusive, except as otherwise provided herein. (c) If such applicant is still dissatisfied with the findings and determinations of the Administration, following the notice and hearing provided for in subsection (b) of this section, a request may be made for rehearing, under such regulations and procedures as the Administration may establish, and such applicant shall be afforded an opportunity to present such additional information as may be deemed appropriate and pertinent to the matter involved. The findings and determinations of the Administration, following such rehearing, shall be final and conclusive upon all parties concerned, except as hereafter provided.
