"As the Full Faith and Credit Clause requires Illinois to recognize the validity of records and judicial proceedings of sister states, the conclusion will not vary because the post-divorce recorded events underlying this litigation took place in other states than Illinois." "Petitioner and Henzel were married in Nevada. Thereafter petitioner brought her putative husband before the New York court. Petitioner and Henzel subjected themselves to the jurisdiction of the New York court and its decree annulling their Nevada marriage was entered with jurisdiction, so far as this record shows, of the parties and the subject matter." "The New York annulment determines the marriage relationship that is the marital status of petitioner and Henzel, just as any divorce judgment determines such relationship. If the Nevada court had had jurisdiction by personal service in the state or appearance in the case of Henzel and the first Mrs. Henzel, its decree of divorce would have been unassailable in other states. So as to the New York decree annulling the marriage, New York had such jurisdiction of the parties and its decree is entitled to full faith throughout the Nation, in Nevada as well as in Illinois."
