Conn. Agencies Regs. § 17-311-105
The rehearing shall be deemed a contested case, which means a proceeding in the commissioner's disposition of matters delegated to his jurisdiction by law, in which the legal rights, duties or privileges of the party are determined by the commissioner after an opportunity for a hearing. The definition stated in Section 4-166(2) of the General Statutes shall further define this term, and all other regulations of the commissioner as appear in the commissioner's description of organization and rules of practice, i.e. Sec. 17-311-27 et seq. shall govern the rehearing procedure. Pursuant to the authority vested in him by Section 17-2, the commissioner may delegate to any deputy, assistant, investigator or supervisor the power to serve as hearing officer or presiding officer and to issue directly the final decision of the department containing findings of fact, conclusions of law and an order. In the alternative, the commissioner may himself preside at the rehearing and issue directly final decision. In the alternative, the commissioner may designate any person to serve as hearing officer or presiding officer and then to submit a proposal for decision to the commissioner pursuant to section 4-179. At such rehearing official notice may be taken of any records maintained in the files of the department, and the hearing officer or presiding officer is authorized to have the assistance of members or representatives of the agency including but not limited to legal and accounting advisors.
