The National Indian Gaming Commission proposes to add a new subchapter to its regulations to create a clear process for appeal proceedings before the Commission. It would, among other things, define certain terms, set forth the burden of proof and standard of review, explain what information a Commission decision will contain, and what happens if the Commission does not issue a majority decision, and provide that an appeal of the Chair's decision does not stay the effect of that decision. The proposed regulations set forth rules for motion practice in appeals before the Commission, addresses how an entity other than a tribe would request to participate on a limited basis in ordinance appeals, how parties file motions to intervene, to supplement the record, and for reconsideration, and how to file motions before the presiding official. Additionally, the proposed regulation sets forth more specific rules for different types of appeals. Rules for appeals of ordinance disapprovals, management contract approvals and disapprovals, appeals before a presiding official, and appeals before the Commission on written submission only each receive somewhat different treatment.
