After appointment, the special assistant shall continue to serve under the direction of the director for a period of time as the director determines is reasonable and necessary or until relieved by order of the commission or of a court of competent jurisdiction. The special assistant's salary, which shall be determined by the director, and expenses shall be borne by the trust company under supervision. After an appointment of a special assistant, a trust company may, within thirty days from the date of the notice of the appointment, appeal in writing to the commission.

The hearing shall be conducted in accordance with the provisions of chapter 1-26. The commission shall render an order as to the correctness or incorrectness of the director's decision to take over the conduct of the trust company, and the order of such commission is subject to review under chapter 1-26.
