In re General Adjudication of All Rights to Use Water in the Gila River System and Source

The Arizona Supreme Court held that the Globe Equity Decree of 1935 precludes the San Carlos Apache Tribe from asserting additional claims to waters of the Gila River, but does not preclude the Tribe’s claims to the waters of the Gila’s tributaries. Even those competing claimants who were not parties to the Decree may assert its preclusive effect under the mutuality exception established by the Supreme Court in Nevada v. United States.
