Supreme Court of the United States, Franchise Tax Board of California v… (2019)
“ Can a private citizen sue one State in the courts of another? Normally the answer to this question is no, because the State where the suit is brought will choose to grant its sister States immunity. But the question here is whether the Federal Constitution requires each State to grant its sister States immunity, or whether the Constitution instead permits a State to grant or deny its sister States immunity as it chooses. ”
