If there are not four (4) employees who are qualified to compete for a promotion, or in case of multiple vacancies, no more than the maximum number available pursuant to the formula in Section 60.09, and where an examination would be superfluous, the Commission, with the consent of the Appointing Authority, may authorize the promotion of the employee(s) nominated; provided, however, that the Commission shall first determine that such employee(s) are qualified for the duties of the higher position(s), and certify those employees found qualified. Such nomination and approval by the Commission and recording in the minutes shall be equivalent to certification from an eligible list by the Commission and appointment pursuant thereto by the Appointing Authority.
