tribal-exhaustion doctrine:
“(1995) The general principle that when an Indian tribal court, original or appellate, has personal and subject-matter jurisdiction, the parties must pursue all remedies available under tribal law before turning to nontribal courts. * A federal court may review a challenge to jurisdiction only after the tribal court has established it has jurisdiction and determined the case on the merits. See National Farmer’s Union Ins. Co. v. Crow Tribe, 471 U.S. 845, 856-57, 105 S.Ct. 2447, 2454 (1985).”
