California Code, Business and Professions Code - BPC § 12203

Except as provided in this section, no person shall hereafter be appointed to the office of county sealer, deputy county sealer, or inspector unless he or she has a license issued by the secretary as provided in Section 12202.  If there is no person available for the position of county sealer who holds a license, the appointing power may make a temporary appointment of a person recommended in writing by the secretary.  If the appointing power does not make a temporary appointment and no person can be appointed from the eligible list by the secretary, then the secretary may make a temporary appointment of a person competent to carry on the duties of the office.  Any temporary appointment shall be for a period not exceeding six months or until the next license examination is held.  If the position of deputy county sealer or inspector cannot be filled from the lists, a temporary appointment may be made, upon the written recommendation of the secretary for a period not exceeding six months.
