(b) A Court of Indian Offenses may not adjudicate an election dispute, take jurisdiction over a suit against a tribe, or adjudicate any internal tribal government dispute, unless the relevant tribal governing body passes a resolution, ordinance, or referendum granting the court jurisdiction.

(c) In deciding who is a tribal official, BIA will give deference to a decision of the Court of Indian Offenses, acting as a tribal forum by resolution or ordinance of a tribal governing body under paragraph (b) of this section.

(d) A tribe may not be sued in a Court of Indian Offenses unless its tribal governing body explicitly waives its tribal immunity by tribal resolution or ordinance.
