Facts

• Austin Land Development Company, Inc., along with its successors and other plaintiffs, filed a lawsuit against the Navajo Tribal Utility Authority (NTUA), a Navajo Nation Enterprise, alleging trespass outside of tribal lands and issues related to the tribal business enterprise's relationship with nonmembers.

Procedural History

• Appeal from the District Court of San Juan County, Karen L. Townsend, District Judge, which dismissed the underlying proceedings due to NTUA's immunity from suit, concluding a lack of subject matter jurisdiction.

Parties' Submissions

• Plaintiffs-Appellants: Argued that the district court should exercise jurisdiction as the case involves a claim of trespass outside of tribal lands and pertains to a tribal business enterprise’s relationship with nonmembers, which should not infringe upon tribal sovereignty.
• Defendant-Appellee (NTUA): Supported the district court's dismissal, emphasizing tribal sovereign immunity that protects NTUA from being sued without its consent or an unequivocal and express waiver of sovereign immunity.

Legal Issues

• Whether the district court erred in dismissing the case for lack of subject matter jurisdiction based on the NTUA's claim of sovereign immunity.

Disposition

• The Court of Appeals affirmed the district court's dismissal of the underlying proceedings for want of subject matter jurisdiction due to NTUA's sovereign immunity.

Reasons

• Per LINDA M. VANZI, J. (MICHAEL D. BUSTAMANTE, J., M. MONICA ZAMORA, J., concurring):
  The Court of Appeals upheld the district court's decision, agreeing that NTUA is immune from suit, which precludes subject matter jurisdiction. The court referenced several precedents affirming the principle that without an express waiver of sovereign immunity or congressional authorization, state courts lack the authority to entertain lawsuits against tribal entities. The plaintiffs' arguments regarding the locus of the disputed activity and the nature of NTUA as a business enterprise were found insufficient to diminish NTUA's entitlement to immunity. The court concluded that the principles of sovereign immunity were correctly applied, and the district court's dismissal for lack of subject matter jurisdiction was proper (paras 2-4).
