An interlocutory appeal asks an appellate court to decide an issue which cannot be resolved on the facts in the case, but whose resolution is essential to a final decision in the case.

On September 26, 1989, the Arizona Supreme Court adopted a Special Procedural Order Providing for Interlocutory Appeals and Certifications. The purpose of the order was to establish a procedure for early review of substantial questions in the Gila River Adjudication. Any party could petition the Arizona Supreme Court to review by interlocutory appeal any ruling of the Superior Court, and the Superior Court could certify to the Supreme Court questions deemed substantial for review.

In February 1990, several parties in the Gila River Adjudication appealed various rulings of the Maricopa County Superior Court. On June 27, 1990, the Arizona Supreme Court consolidated the petitions for interlocutory review. On December 11, 1990, the Court granted review on six issues. Each issue was argued and decided separately. The issues and their determinations are:

  1. Do the procedures for filing and service of pleadings adopted by the trial court in its Pretrial Order Number 1 comport with due process under the United States and Arizona Constitutions?

    In the Matter of the Rights to the Use of the Gila River (March 19, 1992) - court held that the procedures for filing and service of pleadings adopted in Pretrial Order Number 1 comport with due process under the United States and Arizona Constitutions. The opinion is reported in 171 Ariz. 230, 830 P.2d 442 (1992).

  2. Did the trial court err in adopting its 50%/90 day test for determining whether underground water is "appropriable" under Arizona Revised Statutes ยง 45-141?

    In re the General Adjudication of All Rights to Use Water in the Gila River System and Source (July 27, 1993) - court held that the 50%/90 day test for identifying wells presumed to be pumping subflow should not be used and remanded the matter to the Superior Court. The opinion is reported in 175 Ariz. 382, 857 P.2d 1236 (1993).

    In re the General Adjudication of All Rights to Use Water in the Gila River System and Source (September 22, 2000) - after the Superior Court held an evidentiary hearing and issued new criteria for determining subflow, court held that the subflow zone is defined as the saturated floodplain Holocene alluvium; all wells located within the lateral limits of the subflow zone, as determined by the Arizona Department of Water Resources (ADWR) are subject to the adjudication; all wells located outside the subflow zone that are pumping water from a stream or its subflow (as determined by ADWR's analysis of the well's cone of depression), are included in the adjudication; and, wells that, though pumping subflow, have a de minimis effect on the river system may be excluded from the adjudication based on rational guidelines for such an exclusion, as proposed by ADWR and adopted by the Superior Court. The opinion is reported in 198 Ariz. 330, 9 P.3d 1069 (2000), cert. denied sub nom. Phelps Dodge Corp. v. U.S., 533 U.S. 941 (2001) (reviewed in August-December 2000 and January-May 2001 Bulletin). On June 25, 2001, the U.S. Supreme Court denied a petition filed by Phelps Dodge Corporation and Arizona Public Service for a writ of certiorari (reviewed in June-August 2001 Bulletin). bbb

  3. What is the appropriate standard to be applied in determining the amount of water reserved for federal lands?

    In re the General Adjudication of All Rights to Use Water in the Gila River System and Source (November 26, 2001) - court held that the purpose of a federal Indian reservation is to serve as a "permanent home and abiding place" to the people living there; the primary-secondary purpose test for quantifying a federal reserved right does not apply to Indian reservations; the practicably irrigable acreage standard is not the exclusive measure to quantify water rights on Indian lands; and, quantifying an Indian reserved right is a fact-intensive, reservation-specific inquiry that must address numerous factors, such as a tribe's master land use plans, history, culture, geography, topography, natural resources, economic base, past water use, present and projected future population, and any others deemed relevant, but proposed uses must be reasonably feasible, and the amount of water adjudicated must be tailored to the reservation's minimal need. The opinion is reported in 201 Ariz. 307, 35 P.3d 68 (2001) (reviewed in September-December 2001 Bulletin).

  4. Is non-appropriable groundwater subject to federal reserved rights?

    In re the General Adjudication of All Rights to Use Water in the Gila River System and Source (November 19, 1999) - court held that federal reserved rights extend to groundwater to the extent groundwater is necessary to accomplish the purpose of a reservation. The opinion is reported in 195 Ariz. 411, 989 P.2d 739 (1999), cert. denied sub nom. Phelps Dodge Corp. v. U.S. and Salt River Valley Water Users' Assn. v. U.S., 530 U.S. 1250 (2000) (reviewed in September-December 1999, January-March 2000, and April-July 2000 Bulletin).

  5. Do federal reserved rights holders enjoy greater protection from groundwater pumping than holders of state law rights?

    In re the General Adjudication of All Rights to Use Water in the Gila River System and Source (November 19, 1999) - court held that holders of federal reserved water rights enjoy greater protection from groundwater pumping than do holders of state law rights to the extent that greater protection may be necessary to maintain sufficient water to accomplish the purpose of a reservation. The opinion is reported in 195 Ariz. 411, 989 P.2d 739 (1999), cert. denied sub nom. Phelps Dodge Corp. v. U.S. and Salt River Valley Water Users' Assn. v. U.S., 530 U.S. 1250 (2000) (reviewed in September-December 1999, January-March 2000, and April-July 2000 Bulletin).

  6. Must claims of conflicting water use or interference with water rights be resolved as part of the general adjudication?

    On April 2, 2002, the Arizona Supreme Court vacated its order granting this appeal and vacated the portion of the Superior Court's order entered on August 1, 1989, relating to the appeal (reviewed in January-April 2002 Bulletin).

    The following are interlocutory appeals arising from orders of the Superior Court.
