Facts

• Hamaatsa, Inc., a non-profit corporation in New Mexico, owns land adjacent to property owned by the Pueblo of San Felipe, a federally recognized Indian tribe. The Bureau of Land Management conveyed the adjacent land to the Pueblo in fee simple, but it is not yet held in trust by the federal government as part of the Pueblo's reservation. Hamaatsa filed a suit against the Pueblo following a dispute over access to a road, Northern R.S. 2477, which traverses the Pueblo's property and provides access to Hamaatsa's land. The Pueblo had informed Hamaatsa that it had no legal right of access and that its use of the road was a trespass (paras 2-4).

Procedural History

• District Court: Denied the Pueblo's motion to dismiss, reasoning the action was an in rem proceeding not seeking damages, to which sovereign immunity was no bar (para 6).
• Court of Appeals: Affirmed the district court's decision, refusing to recognize tribal sovereign immunity based on the Pueblo's lack of evidence of property or governance interests in the road (para 7).

Parties' Submissions

• Plaintiff-Respondent (Hamaatsa, Inc.): Argued that Northern R.S. 2477 has been used by the public and its predecessors to access its property since at least 1935, and that the road vested in the public as a state highway under R.S. 2477. Contended that the Pueblo cannot restrict Hamaatsa’s use of the road (para 5).
• Defendant-Petitioner (Pueblo of San Felipe): Asserted sovereign immunity, arguing that it deprived the district court of subject matter jurisdiction. Claimed that there is no public road across its property that Hamaatsa may lawfully access and that Northern R.S. 2477 is but one point of access to Hamaatsa’s property (paras 5-6).

Legal Issues

• Whether the Pueblo of San Felipe, as a sovereign tribal nation, is immune from Hamaatsa’s suit.
• Whether considerations of equity and fairness should override the Pueblo's immunity from suit.
• Whether the Court of Appeals misapplied Rule 1-012(B) with respect to the Pueblo’s motion to dismiss on sovereign immunity grounds (para 16).

Disposition

• The Supreme Court of the State of New Mexico reversed the Court of Appeals and instructed the district court to enter an order dismissing Hamaatsa’s suit (para 41).

Reasons

• The Supreme Court, per Justice Vigil, held that under federal law, the Pueblo is immune from suit, absent a waiver of its immunity or congressional authorization of the suit—regardless of the nature of the claim giving rise to the dispute. The Court clarified that tribal sovereign immunity is a matter of subject matter jurisdiction and can be asserted by a Rule 1-012(B)(1) motion to dismiss. It rejected Hamaatsa's arguments for exceptions to tribal sovereign immunity based on the nature of the proceedings (in rem vs. in personam) and the type of relief sought (declaratory vs. monetary). The Court emphasized that tribal sovereign immunity is a necessary corollary to Indian sovereignty and self-governance, protected from diminution by individual states. It concluded that the Pueblo properly raised its tribal sovereign immunity at the stage of the proceedings by Rule 1-012(B) motion to dismiss, and that the Court of Appeals erred in concluding otherwise (paras 18-41).
