Conn. Agencies Regs. § 47-59b-6
At the time a representative of a tribal organization requests to be seated at the Council, or any time thereafter, a member of the tribe for which the representative was selected, or any person aggrieved by an action of this Council, may challenge the authority of the tribal organization seeking to be seated to represent the tribe, or the validity of the process by which the representative of the tribe was selected. Upon receipt of such a challenge, the Council shall set a date for a hearing to be held and conducted in the same manner as hearings on contested applications for recognition of Indian status under these regulations. No representative shall take part in proceedings of the Council while under challenge. The burden of proof shall be on the challenger. If the Council determines that the tribal organization represents the tribe and that the challenged representative has been properly selected by the tribal organization, the Council will not entertain further challenges to the tribal organization or its representative except on a showing of substantial evidence different from that heard by the Council at the first challenge hearing. The burden shall be upon the challenging party to show, by affidavit or document any evidence, that new evidence warrants a hearing on any subsequent challenge.
The Commissioner of Environmental Protection may, and in the event that more than one member are challenged simultaneously shall, designate one or more additional persons, who shall be Indians within the meaning of Sections 47-59a to 47-66 of the General Statutes, as amended, and not members of the tribal organization under challenge, to sit on the Council for purposes of hearing and determining the challenges. The panel shall consist of not less than seven persons, including the Council members whose credentials have not been challenged.
