(a) Extraordinary appointments include temporary appointments, emergency appointments, exceptional appointments and provisional appointments.

(b) Whenever the services to be rendered by an appointee are for a temporary period not to exceed 104 workdays and the need for such service is important and urgent, the director may select for such temporary service any person on the proper eligible register without regard to his standing on such register. Successive temporary appointments to the same position or of the same candidate shall not be made under this provision. The acceptance or refusal by an eligible of such temporary appointment shall not affect his standing on the register for regular employment, nor shall a period of temporary service be counted as a part of the probationary service in case of subsequent appointment to a regular position.

(c) Whenever there is an emergency condition existing in the service, appointment may be made of a noneligible person to perform work in such position and under such conditions, but in no case shall such appointment be continued for more than 10 days, and in no case shall successive emergency appointments be made.

(d) Whenever there is a vacancy in a position in the classified service where peculiar and exceptional qualifications of a scientific, professional or educational character are required and upon satisfactory evidence that for specified reasons competition in such special case is impracticable and that the position can best be filled by the selection of some designated person of high and recognized attainments in such qualities, the personnel board upon recommendation of the personnel director may suspend the examination requirements in such case, but no suspension shall be general in its application to such place or position, and all such cases of suspension shall be reported in the annual report of the department with the reasons for such action in each case.

(e) Whenever it is impossible to certify eligible persons for appointment to a vacancy in the classified service, the appointing authority may nominate a person to the director. If such nominee is found by the director to have had experience and training which appear to qualify him for the position, the director may authorize the appointment of such person to such vacancy only until an appropriate eligible register can be established and appointment made therefrom. In no event shall a provisional appointment be continued for more than 156 workdays. Successive provisional appointments of the same person shall not be made.

(f) When the Governor declares that an emergency warranting such action exists, such as a war or other national emergency that causes serious manpower problems, limited tenure appointments may be made. Qualification standards may be lowered in such cases, but whenever practicable there shall be competition among those meeting the lowered standards for such appointments. The personnel director may, however, in the absence of any appropriate lists, authorize a limited tenure appointment without examination. In either case such appointments shall be for not longer than the "duration plus six months" and shall give persons so appointed no status in the classified service by reason of such durational appointment. Such limited tenure appointments shall be made by the authority designated by law in accordance with the provisions of this article.
