Whether the Court had appellate jurisdiction to review the California Court of Appeal’s ruling despite unresolved claims concerning the Flood Control District and questions about how the federal issue was raised.
Holding
Yes. The Court had jurisdiction because the state court had finally resolved a distinct federal compensation issue that would survive regardless of the outcome of the remaining state-law proceedings.
Reasoning
The unresolved cloud-seeding claim against the Flood Control District did not prevent review. The California Court of Appeal had conclusively rejected the Church’s separate claim that it was constitutionally entitled to compensation from the County for a regulatory taking, and that federal issue would remain decisive no matter how the other claims were resolved.
Although the Church’s complaint invoked state constitutional law, it argued in the Court of Appeal that federal takings decisions showed the constitutional error in California’s Agins rule. By applying Agins and rejecting that argument, the state court actually decided the federal question. The Court therefore treated the claim as adequately raised and passed upon below.
