Facts

The City of Las Vegas claimed water rights under the "pueblo rights doctrine," which grants municipalities tracing their origins to Spanish or Mexican pueblos a paramount right to water from non-navigable streams for future growth. This doctrine was first recognized in New Mexico in Cartwright v. Public Service Co. (1958). The State Engineer challenged the validity of this doctrine, arguing it lacked historical basis and conflicted with New Mexico's prior appropriation water law (paras 1-3, 11, 20-22).

Procedural History

• Cartwright v. Public Service Co., 66 N.M. 64, 343 P.2d 654 (1958): The New Mexico Supreme Court recognized the pueblo rights doctrine, granting municipalities certain water rights.
• City of Las Vegas v. Oman, 110 N.M. 425, 796 P.2d 1121 (Ct. App. 1990): The Court of Appeals held that Cartwright had stare decisis effect but remanded the case for further factual determinations, including the historical validity of the pueblo rights doctrine.
• District Court, (N/A): The trial court recognized the City's claim to pueblo water rights but declined to address the historical validity of the doctrine, considering itself bound by Cartwright and Oman (paras 3-4).

Parties' Submissions

• Plaintiff-Appellee/Cross-Appellant (State Engineer): Argued that the pueblo rights doctrine is historically invalid, lacks support under Spanish and Mexican law, and is incompatible with New Mexico's prior appropriation system of water rights (paras 4, 11, 20-22, 26-28).
• Defendant-Appellant/Cross-Appellee (City of Las Vegas): Contended that the pueblo rights doctrine is valid, relied on Cartwright and California case law, and argued that it had relied on the doctrine for its water use and infrastructure investments (paras 4, 12-13, 29-30).

Legal Issues

• Whether the pueblo rights doctrine, as established in Cartwright v. Public Service Co., is historically valid under Spanish and Mexican law.
• Whether the pueblo rights doctrine is compatible with New Mexico's prior appropriation system of water rights.
• Whether the City of Las Vegas reasonably relied on the pueblo rights doctrine for its water use and infrastructure investments.

Disposition

• The Court of Appeals reversed the trial court's recognition of the City's pueblo water rights and held that the pueblo rights doctrine is invalid (para 32).
• The case was remanded for further proceedings consistent with the opinion (para 32).

Reasons

Per Apodaca J. (Alarid J. concurring):

Historical Invalidity of the Pueblo Rights Doctrine:
The Court found that the pueblo rights doctrine lacks historical support under Spanish and Mexican law. Modern scholarship overwhelmingly refutes the existence of such rights, emphasizing equitable water distribution rather than exclusive municipal rights. The doctrine's reliance on a single passage from Escriche's legal dictionary was deemed insufficient to establish its validity (paras 11-25).

Incompatibility with Prior Appropriation Law:
The Court held that the pueblo rights doctrine conflicts with New Mexico's prior appropriation system, which requires water rights to be supervised and measured by the State Engineer. The doctrine's unlimited growth-based water rights are inconsistent with statutory limits on municipal water use planning periods and could disrupt interstate water compacts (paras 26-28).

City's Reliance on the Doctrine:
The Court rejected the City's argument that it reasonably relied on the pueblo rights doctrine, noting that Cartwright did not define legitimate uses of water under the doctrine. The City's reliance was therefore not justified (paras 29-31).

Per Hartz J. (concurring in part, dissenting in part):

Hartz J. agreed that the pueblo rights doctrine is invalid and should be overruled. However, he dissented in part, arguing that the City of Las Vegas might still possess some rights arising from the Supreme Court's decision in Cartwright. He would leave this issue for the district court to address on remand (paras 34-35).
