Here are the materials in Coeur d’Alene Tribe v. Hawks (D. Idaho):
But here, the Hawks have not challenged the Tribal Court‘s jurisdiction to make the award, and the Tribe has not sought a declaratory judgment that its courts had jurisdiction over the Hawks. Instead, the Tribe is simply asking a federal court to domesticate and enforce a Tribal Court Judgment. While such a claim has a basis in Idaho law and can be enforced in Idaho courts pursuant to Idaho Code § 10-1401 et. seq., the Tribe cites no federal statute or law that is in dispute and that could be used to create a federal question.
