Each commissioner is an enforcing officer of all laws and regulations which relate to the prevention of the introduction into, or the spread within, the state of pests. He is, as to such activities, under the supervision of the director.

Each commissioner and each qualified representative of the commissioner is a state plant quarantine officer for the following purposes:

Any interested person that is aggrieved by any action or order of a commissioner may appeal in writing to the director within five days after notice of action or order if no other time limit is prescribed within which to appeal from such action or order. No appeal may be taken from any authorized summary action of the commissioner.

The director shall hear any appeal from an action or order of a commissioner within 10 days after the receipt of the appeal upon notice to all interested parties. His decision shall be final.

Pending decision after appeal, action by the commissioner on the case under appeal shall be suspended by the director. The refusal of any commissioner to carry out the orders and directions of the director which are issued in connection with any appeal is neglect of duty.
