Here is the opinion in Cherokee Nation v. Bernhardt (N.D. Okla.):
Prior post here.
Here is the petition:
1. Whether the Secretary of the Interior exceeded his statutory authority by taking land located within the reservation boundaries of one Indian Tribe and placing the land in trust for another Tribe, despite the objections of the first Tribe and in violation of a regulatory prohibition and the United States’ treaty promises to the first Tribe.
2. Whether the Court should hold this petition pending its disposition of Maine Community Health Options v. United States, No. 18-1023 (argued Dec. 10, 2019), because this case raises the same issue concerning implied repeals effected by appropriations laws and the proper standard for determining what law to apply.
