for the commission of a maritime tort, upon the theory relied upon.”
We repeat, the immunity of a State from suit in personam in the admiralty brought by a private person without its consent, is clear.
As to what is to be deemed a suit against a State, the early suggestion that the inhibition might be confined to those in which the State was a párty to the record (Osborn v. United States Bank, 9 Wheat. 738, 846, 850, 857) has long since been abandoned, and it is now established that the question is to be determined not by the mere names of the titular parties but by the essential nature and. effect of the proceeding, as it appears from the entire record. Louisiana v. Jumel, 107 U. S. 711, 719, 720, 723, 727-728; Hagood v. Southern, 117 U. S. 52, 67, et seq.; In re Ayers, 123 U. S. 443, 487-492; Pennoyer v. McConnaughy, 140 U.

S. 1, 10: “The first class is where the suit is brought against the officers of the State, as representing the State’s action and liability, thus making it, though not a party to the record, the real party against which the judgment will so operate as to compel it to specifically perform its contracts [citing cases]. The other class is where a suit is brought ¿against defendants who, claiming to act as officers of the State, and under the color of an unconstitutional statute, commit acts of wrong and injury to the rights and property of the plaintiff acquired under-a contract with the State. Such suit ... is not, within the meaning of the Eleventh * Amendment, an action' against the State.” The first class, in just reason, is not confined to cases whtere the suit will operate so as to com
