Here is the petition in Glacier Electric Cooperative, Inc. v. The Estate of Scott Sherburne: Glacier Electric Cert Petition.
Questions presented:
[T]he question presented is whether preclusion of the issue of tribal subject matter jurisdiction to hear a case bars the federal courts from considering whether Respondents may enforce in tribal court the relief they were granted there – a substantial money judgment – despite the lack of due process at the trial.
The Ninth Circuit’s summary disposition is here.
