§ 106. Jurisdiction of council to determine disputes. The chiefs of
such tribe in council assembled may hear and determine charges of
encroachment or trespass on lands cultivated or occupied by any Indian,
entered or described in the clerk's book of records; and controversies
involving the title to property between individual Indians residing on
such reservation. A chief shall not act in any such case where he is
related by blood to either of the parties within the fourth degree by
the common law, or has any interest in the action or proceeding.
