Facts

The case concerns the City of Las Vegas, which claimed a pueblo water right based on an 1835 colonization grant from the Republic of Mexico. This right purportedly allowed the City to take as much water as necessary for municipal purposes, with the right expanding to meet population growth. The State Engineer challenged the validity of the pueblo rights doctrine, arguing it conflicted with New Mexico's system of prior appropriation, which is based on beneficial use (paras 1-2, 13).

Procedural History

• Cartwright v. Public Service Co. of New Mexico, 1958-NMSC-134: The New Mexico Supreme Court recognized the pueblo rights doctrine, holding that municipalities succeeding colonization pueblos had a superior water right (paras 1, 6-10).
• State ex rel. Martinez v. City of Las Vegas, 1994-NMCA-095: The Court of Appeals declined to follow Cartwright, determining that the pueblo rights doctrine was invalid and inconsistent with New Mexico water law (paras 2, 16-19).
• District Court, 2003: The district court, bound by stare decisis, declined to rule on the validity of the pueblo rights doctrine but limited the scope of the City's pueblo water right to municipal purposes within city limits, excluding industrial uses, groundwater, and reservoirs (paras 15, 17).

Parties' Submissions

• State Engineer: Argued that the pueblo rights doctrine lacked historical basis in Spanish and Mexican law and conflicted with New Mexico's system of prior appropriation, which is based on beneficial use. The State Engineer also contended that the City's water rights should be determined by prior appropriation (paras 2, 24, 33).
• City of Las Vegas: Defended the pueblo rights doctrine, asserting that it was historically valid and protected by the Treaty of Guadalupe Hidalgo. The City argued that it had relied on the doctrine for decades in planning and operating its water system (paras 25, 53).

Legal Issues

• Was the pueblo rights doctrine historically valid under Spanish and Mexican law?
• Is the pueblo rights doctrine consistent with New Mexico's system of prior appropriation and beneficial use?
• Should the overruling of the pueblo rights doctrine apply retroactively or prospectively?

Disposition

• The New Mexico Supreme Court overruled the pueblo rights doctrine, holding that it is inconsistent with New Mexico water law and not protected by the Treaty of Guadalupe Hidalgo (paras 69-70).
• The Court applied its ruling retroactively but provided a limited prospective application for the City of Las Vegas, remanding the case to determine an equitable remedy (paras 69-70).

Reasons

Per Serna J. (Maes CJ., Bosson J., and Chávez J. concurring):

• Historical Basis: The Court found that the pueblo rights doctrine lacked a clear historical foundation in Spanish and Mexican law. However, it declined to overrule Cartwright solely on this basis, as the historical evidence was not definitive (paras 24-31).

• Conflict with Prior Appropriation: The Court determined that the pueblo rights doctrine was fundamentally inconsistent with New Mexico's water law, which is based on prior appropriation and beneficial use. The doctrine's indefinite expansion and immunity from forfeiture conflicted with principles of certainty, conservation, and equitable distribution (paras 33-38).

• Treaty of Guadalupe Hidalgo: The Court held that the Treaty did not protect the expanding nature of pueblo water rights, as such rights were inchoate and subject to the sovereign's discretion (paras 39-41).

• Stare Decisis and Rule of Property: While acknowledging the importance of stare decisis, the Court concluded that the pueblo rights doctrine was a "doctrinal anachronism" and a detriment to New Mexico water law. It rejected the City's argument that Cartwright established a rule of property inducing substantial reliance (paras 43-47).

• Equitable Remedy: The Court recognized the City's reliance on Cartwright and the potential for inconsistent judgments. It remanded the case to the district court to determine an equitable remedy balancing the City's reliance interests with the rights of other water users and the State Engineer's regulatory responsibilities (paras 48-68).
