(A) Evidence. The Court shall not be bound by common law rules of evidence, but shall use its own discretion as to what evidence it deems necessary, reliable and relevant to the action. The Tribal Court has the discretion to rely on Federal Rules of Evidence or relevant state evidentiary or procedural rules for guidance. Informal disclosures shall be favored, subject to the right of a party to show privilege or other good cause not to disclose specific material or information. Parties shall disclose any evidence or information within their possession or control favorable to the other parties.
(B) Tribal Custom. Where any doubt arises as to the customs of the Tribe, the Court may request the advice of elders or other credible individuals familiar with those customs.
