Here is the opinion in Pueblo of Pojoaque v. State of New Mexico.

An excerpt:

Plaintiffs-Appellants Pueblo of Pojoaque and its governor, Joseph M. Talachy, (collectively “the Pueblo”) appeal from the district court’s dismissal of its claim for declaratory and injunctive relief based on the State of New Mexico’s alleged unlawful interference with Class III gaming operations on the Pueblo’s lands. Pueblo of Pojoaque v. New Mexico, 214 F. Supp. 3d 1028 (D.N.M. 2016). Exercising jurisdiction under 28 U.S.C. § 1291, we affirm.

From the dissent:

This appeal turns on what constitutes regulation of tribal gaming.
The majority answers narrowly, stating that New Mexico is regulating Indian gaming only when the regulation is directly applied to Indian gaming on tribal land. In my view, this approach is unsupportable and unrealistic. Under the allegations in the Pueblo’s complaint, New Mexico is trying—with considerable success—to disrupt the Pueblo’s gaming operations by targeting the Pueblo’s vendors. This disruption is not
softened by the state’s strategy of targeting vendors.
