Here is the opinion in Northern Cheyenne Tribe v. Roman Catholic Church ex rel. Dioceses of Great Falls/Billings:

NCT v Catholic Church

An excerpt:

We reverse and remand the District Court’s decision to grant summary judgment to the Diocese and St. Labre on NCT’s claim for unjust enrichment and the imposition of a constructive trust that may arise from St. Labre’s fundraising activities after 2002. The court improperly determined that NCT had to establish evidence of loss by NCT or  wrongdoing by the Diocese and St. Labre in order to make out a claim for unjust enrichment. We also reverse and remand the District Court’s decision to grant summary judgment to the Diocese and St. Labre regarding St. Labre’s fundraising activities before 2002. The District Court should evaluate in the first instance the accrual date of NCT’s unjust enrichment claim pursuant to the standards set forth herein. The District Court can address on remand those defenses raised by the Diocese and St. Labre not resolved through the summary judgment proceedings. We affirm the District Court’s grant of summary judgment on all of NCT’s remaining claims.
