Comity of Nations (Hilton v. Guyot) - "Comity," in the legal sense is neither a matter of absolute obligation, on the one hand, nor of mere courtesy and good will, upon the other. But it is ,the recognition which one nation allows within its· territory, to the legislative, executive or judicial acts of another nation,, having due regard both to international duty other and convenience, and to the rights of its own citizens or, of other person who are under the protection of its laws.
Recognition of one nation of the acts of another nation, having due regard both to international duty other and convenience, and to the rights of its own citizens or, of other person who are under the protection of its laws.
- Not an obligation - because laws have no effect outside territory of legislature.
- Not Courtesy/Good Will - because duty of State to promote international relations. Recognition of the fact that if no recognition, then each state will have to be relitigated
Distinguished from Reciprocity - Recognition is comity, reciprocity is exchange of rights.
