Separately, sovereign immunity of a state from lawsuits in other states have been in question. The Supreme Court ruled in Nevada v. Hall (1977) that states are not constitutionally immune from being named in lawsuits filed in other states. In the intervening years, many states developed legislation that recognize sovereign immunity of other states; since 1979, there had only been 14 legal cases that did involve a state being named as a litigant in a case heard in another state. The Supreme Court overturned Nevada in its 2019 decision of Franchise Tax Board of California v. Hyatt (Docket 17-1299) that states did enjoy constitutional sovereign immunity from lawsuits in other states.
