Registrar registration applications may be rejected after hearing; applicants can seek reconsideration within thirty days. Regulation 13 permits the Board to reject an application for registration after giving the applicant a reasonable opportunity of being heard, and requires the Board to communicate its decision and the grounds for rejection to the applicant within thirty days. An aggrieved applicant may seek reconsideration within thirty days of receipt of the intimation, upon which the Board must reconsider and communicate its written findings as soon as possible.
