When a licensee has made timely and sufficient application for renewal of a license, the existing license shall not expire until the application for renewal has been finally determined, or in case of a determination adverse to the licensee until the last day for seeking review of the Board's order or a later date fixed by order of the reviewing court. If a licensee does not make a timely and sufficient application for renewal of a license prior to the twenty-ninth day of August of each year in question, then said person's license shall be suspended.
