The Tribe or any lessor may petition the Tribal Court to intervene in any lease or leasehold mortgage foreclosure proceeding under this chapter. Neither the filing of a petition for intervention by the Tribe, nor the granting of such a petition by the Tribal Court shall operate as a waiver of the sovereign immunity of the Tribe, except as may be expressly authorized by the Tribe. [Res. 15-R-147 § 11, 12/3/2015.]
