On October 6, 2025, the Supreme Court declined review in two Ninth Circuit cases that imposed legal duties on Uber based on legal predictions—not precedent. The denial was a disappointment for WLF, which filed an amicus brief urging review. WLF’s brief argued that the appeals court’s guessing game conflicts with Erie and threatens federalism. Federal courts, it contended, may not substitute speculation for settled law. WLF warned that guessing at state law harms litigants, muddles doctrine, and strips power from courts and officials. WLF asked the Court to restore the boundary between state and federal authority and reaffirm the principle that state law must come from the State’s own courts.
