Every order of the department requiring performance of certain acts or compliance with certain requirements and any denial or revocation of any approval, certificate or license shall set forth the reasons and shall state the acts to be done or requirements to be met before approval by the department will be given or the approval, license or certificate granted or restored, or the order modified or changed. Orders issued by the department pursuant to this chapter shall be served upon the persons affected either by registered mail or in person. In every case where notice and opportunity for hearing are required under this chapter, except by agreement of the parties, the order of the department shall, on not less than ten (10) days' notice, specify a time when and place where the person affected may be heard, or the time within which the person may request a hearing, and the order shall become effective upon the expiration of the time for exercising the opportunity for hearing, unless a hearing is held or requested within the time provided, in which case the order shall be suspended until the department affirms, disaffirms or modifies such order after hearing held or default by the person affected. To the extent practicable, a hearing on the order shall be held in the county where the affected person resides or does business. Any person aggrieved by an order of the department or by the grant, denial, or revocation of any approval, license or certificate may have the action of the department reviewed by the courts of this state in the manner provided for, and subject to the rules of law applicable to, the review of the orders of other administrative bodies of the state, as set forth in title 27, chapter 9.
