An excerpt:
The Court at this juncture simply must determine whether Blackfeet Tribal Court “plainly” lacks jurisdiction. The IHS facility sits on leased Indian land. This fact, by itself, amounts to a colorable claim of jurisdiction. The Blackfeet Tribal Court maintains a colorable claim of jurisdiction based on the alleged conduct on tribal trust land. This determination precludes analysis at this point as to whether either Montana exception provides a colorable basis for Blackfeet Tribal Court jurisdiction. Admiral Ins. Co. v. Blue Lake Rancheria Tribal Ct., 2012 WL 1144331 (N.D. Cal. 2012).
