410.653—Vacation of dismissal of request for hearing.
A presiding officer or the Appeals Council may, on request of the party and for good cause shown, vacate any dismissal of a request for hearing at any time within 60 days after the date of receipt of the notice of dismissal by the party requesting the hearing at his last known address. For purposes of this section, the date of receipt of the dismissal notice shall be presumed to be 5 days after the date of such notice, unless there is a reasonable showing to the contrary. In any case where a presiding officer has dismissed the hearing request, the Appeals Council may, on its own motion, within 60 days after the mailing of such notice, review such dismissal and may, in its discretion vacate such dismissal.
