The opinion is reported in 194 Ariz. 68, 977 P.2d 790 (1999). The case was reviewed in the February 1999 and April-July 1998 issues of the Bulletin.

  • United States v. Superior Court, 144 Ariz. 265, 697 P.2d 658 (1985) - in special action proceeding, court held that state courts have jurisdiction to adjudicate Indian claims to water rights and may do so in general adjudications; a general adjudication is not a claim to Indian title, therefore, disclaimer provision of Arizona Constitution is not an impediment to adjudication in state courts of Indian water rights; and, procedures contained in Arizona's general adjudication statutes do not violate the Arizona or federal constitutional due process guarantees.
  • This 1985 decision of the Arizona Supreme Court followed the opinion of the United States Supreme Court in Arizona v. San Carlos Apache Tribe of Arizona, 463 U.S. 545 (1983), where the Court held that the McCarran Amendment removed whatever limitations the Enabling Acts or federal policy may have originally placed on state court jurisdiction over Indian water rights, and state courts have jurisdiction to adjudicate Indian water rights.
