Here is the unpublished memorandum in Roberts v. Elliott (In re Roberts Litigation).
An excerpt:
The Supreme Court has not addressed the interaction between Oliphant’s rejection of inherent criminal jurisdiction over non-Indians and a non-Indian’s ability to waive the question of personal jurisdiction before the tribal court in criminal matters. The extent to which a non-Indian may consent to tribal jurisdiction is not settled law. Smith v. Salish Kootenai Coll., 434 F.3d 1127, 1136–40 (9th Cir. 2006) (en banc) (discussing non-tribal member consent to jurisdiction in civil suits).
