The commissioner may revoke, suspend or refuse to renew the registration of service persons or scale mechanics if he determines that the person has failed to abide by the rules and regulations promulgated under this law or has removed a condemnation tag, for purpose other than that of repair, or no longer qualifies under the above rules and regulations. The taking of unfair advantage of an owner of a weighing or measuring device or unsatisfactory work in repairing said devices shall also constitute grounds for refusing to register, revocation, suspension or nonrenewal of the registration.

The Commissioner of Agriculture and Industries shall give at least 10-days' written notice by certified mail to the concerned person prior to refusing to register, revocation, suspension or nonrenewal of the registration. The notice shall set out the specific grounds under which the action was taken. The registrant or proposed registrant, after receiving notification as set out above, may request a hearing before the commissioner. This request must be in writing and be received by the commissioner within 10 days after receiving notice of the commissioner's intended action. If the written request for a hearing is received within the 10-day period, the commissioner shall stay his intended action pending the outcome of the hearing. Any adverse ruling at this hearing is appealable to the State Board of Agriculture and Industries provided notice of appeal to the board is given in writing to the commissioner within 10 days after receiving written notice of an adverse ruling. The hearing before the State Board of Agriculture and Industries shall follow the proceedings affecting licensees under the Alabama Administrative Procedures Act (§41-22-1 et seq.).
