Here are the materials in State of New Mexico v. Dept. of Interior (D. N.M.):
Plaintiff State of New Mexico challenges the Department of the Interior and the Secretary of the Interior’s legal authority to implement regulations found in 25 C.F.R. § 291 (“Secretarial Procedures” or “Part 291 regulations”). The Secretarial Procedures, if adopted, would allow the Pueblo of Pojoaque to conduct Class III gaming on its reservation. New Mexico asks this Court to declare the Secretarial Procedures invalid because they conflict with the unambiguous terms of the Indian Gaming Regulatory Act (“IGRA”), 25 U.S.C. § 2701 et seq. and violate New Mexico’s sovereign immunity under the Eleventh Amendment.
