United States 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. In the case of Bank of Agusta v Earl, the court adopted Justice Joseph Story's doctrine of comity. At the end of the nineteenth century, the US Supreme Court delivered the classic statement on comity in the decision of
Hilton v. Guyot (1895). The court stated 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: This case continues to be the leading case cited by American courts when articulating the doctrine of comity. It is an important decision for the country as it articulates the definition of comity and does so in a more broad way than previously. Despite the broad definition in Hilton v Guyot, the court refused to enforce the French judgment based on reciprocity, as France would not have enforced an equivalent judgment. After the
Cold War, the Supreme Court heard the case of Hartford Fire Insurance Co v California. In this case, Justice Souter gave the opinion that one only considers comity where there is a "true conflict between domestic and foreign law". In the dissent, Justice Scalia argues that extraterritorial jurisdiction must consider international comity to ensure international law is not violated. 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."
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.
England and Wales By the end of the nineteenth century, comity had received judicial approval in
English law as a foundational principle to private international law. In 1896, Professor
Dicey published "Digest of the Law of England with Reference to the Conflict of Laws" that criticized the doctrine of comity on the basis that it is too vague as it promoted the recognition of foreign laws depending on option. The case law indicates that comity is relevant in the consideration of determining what effect another state's laws or judicial power should have in England in a given case.
Morguard Investments Ltd. v De Savoye was the first case in this series considering comity in Canadian law. The common law reflected the principle from England that one of the basic tenets of international law is that sovereign states have exclusive jurisdiction in their territory. Therefore, before this decision, Canadian courts were conservative in recognizing foreign judgments, including those obtained in other Canadian provinces' courts. Justice La Forest acknowledges that the common law approach is not grounded in the realities of modern times as states cannot live in complete isolation due to travel, flow of wealth, skills and people. These extraterritorial effects of provincial legislation will be assessed according to the principle of comity. The court determines that the law of where the tort occurred should apply, this is known as lex loci delicti. Justice La Forest clearly reaffirmed the importance of comity in private international law in the decision.
Australia The Australian Constitution recognizes that the Full Faith and Credit should be afforded by the Commonwealth and each state to all other Australian states: In case law, the
High Court of Australia has never defined the meaning of comity in Australian law. Comity has played an important role in the development and application of Australian private law.
European Union The
Brussels 1 Regulation requires that the judgment of the court of one member states of the
European Union (absence non-consenting defendants) shall be enforced by the court of another member state. ==See also==
