apply." This idea was rejected by Justice Joseph Story of the Supreme Court, who agreed with Mansfield and Huber in his Commentaries on the Conflict of Laws. Story's view, which ultimately prevailed, was that the consensual or voluntary application of comity doctrine would foster trust among states, "localize the effect of slavery," and reduce the risk of civil war. The U.S. Supreme Court's holding in Hilton v. Guyot (1895) that the enforcement of a foreign judgment was a matter of comity is viewed as the "classic" statement of comity in international law. The Court held in that case: In the United States, certain foreign defamation judgments are not recognized under the SPEECH Act (a federal statute enacted in 2010), which supersedes the comity doctrine. The Act aims to stop "libel tourism." United States Constitution In the law of the United States, the Comity Clause is another term for the Privileges and Immunities Clause of the Article Four of the United States Constitution, which provides that "The Citizens of each State shall be entitled to all Privileges and Immunities of Citizens in the several States." Article Four as a whole—which includes the Privileges and Immunities Clause, the Extradition Clause, and the Full Faith and Credit Clause—has been described as the "interstate comity" article of the Constitution. Professional licensure In the United States, some states and territories recognize professional engineer licenses granted in a different jurisdiction, depending on the holder's education and experience (a practice called "licensure by comity"). Rules differ significantly from jurisdiction to jurisdiction. See also Act of state doctrine Alien Tort Statute Forum non conveniens Lex loci Hartford Fire Insurance Co. v.
