Recently, a federal judge in Nebraska stayed a federal claim that the Omaha tribe has no authority to require on-reservation, non-Indian liquor vendors to obtain a tribal license to sell liquor.
The judge noted that this appears to be a question of first impression (“While the briefing has been excellent, neither side has given me a case that is squarely on point regarding whether exhaustion is required in these circumstances. As a result, I must read the ‘tea leaves.'”), but correctly stayed the case until the tribal court had a chance to opine on the jurisdiction questions.
