When a vacancy occurs in the office of judge of any court of record, the vacancy shall not be filled until, after investigation, the Supreme Court certifies that the filling of the vacancy is or is not necessary. If the Court certifies that the filling of the vacancy is necessary, the Court shall publish notice of such certification in a publication of general circulation among attorneys licensed to practice in the Commonwealth. No notice of retirement submitted under § 51.1-305 or § 51.1-307 shall be revoked after certification of the vacancy by the Court. If the Court certifies that the filling of the vacancy is not necessary, it shall recommend to the General Assembly the manner of distributing the work of the judge; and the Governor shall not fill the vacancy.
