uh... I think the real threat and the topic of this article has to do with AZ being sued in an international court of jurisdiction.
International courts have no jurisdiction in the US;
U.S. and the World Court
In 1946, the U.S. accepted an optional clause in the Court's statute -- that gave the Court compulsory jurisdiction over cases regarding interpretation of treaties, any question of international law and any breach of international obligations. In 1984, Sandinista-ruled Nicaragua filed a suit against the U.S for its support of the Contra rebels. In response, the Reagan administration promptly withdrew U.S. recognition of the World Court's compulsory jurisdiction.
There are no international courts of jusisdiction over a state of the United States.
There are very few international courts that the US even acknowledges (regardless of what the Democrats have taught you to believe). And none of these have jurisdiction over State matters.
