Nevada v. Hall
Nevada v. Hall, 440 U.S. 410 (1979), was a United States Supreme Court case that ruled that U.S. states lack sovereign immunity from private lawsuits filed against them in the courts of another state. The majority opinion held that "nothing in the Constitution authorizes or obligates" states to grant sister states immunity in court. States may grant sister states immunity if they choose. This decision was overturned by the 2019 case "Franchise Tax Board of California v. Hyatt".
