The question is whether, in the absence of the adoption of any guiding policy by the Executive branch of the government the federal courts should recognize the immunity from a suit in rem in admiralty of a merchant vessel solely because it is owned though not possessed by a friendly foreign government.

Respondent, owner and master of the Lottie Carson, an American fishing vessel, filed a libel in rem in the district court for southern California against the Baja California, her engines, machinery, tackle and furniture, for damage alleged to have been caused when the Baja California negligently caused her two to collide with the Lottie Carson in Mexican waters. The Mexican Ambassador to the United States, acting in behalf of his government, thereupon filed in the district court a suggestion that the Baja California at all the times mentioned in the libel and at the time of her seizure was owned by the Republic of Mexico and in its possession, and engaged in the transportation of cargoes between the ports of the Republic of Mexico and elsewhere. Libellant put in issue the allegations of the suggestion that title to the Baja California was at any time in the Mexican government and denied that she was in that government's possession, public service or use. Trial of these issues proceeded upon stipulated evidence.

In the meantime the United States Attorney for the District, acting under direction of the Attorney General, filed in the district court a communication from the Secretary of State to the Attorney General, in which the State Department called attention to the claim of the Mexican government, already detailed. The Department took no position with respect to the asserted immunity of the vessel from suit other than to cite Ervin v. Quintanilla, 5 Cir., 99 F.2d 935, and Compania Espanola De Navegacion Maritima, S.A. v. The Navemar, 303 U.S. 68, 58 S.Ct. 432, 82 L.Ed. 667. In Ervin v. Quintanilla, supra, the asserted immunity from suit of The San Ricardo, a vessel of the Mexican government, was allowed by the court on the ground that at the time of her seizure upon a libel in rem she was in the possession and service of that government. And in Compania Espanola v. The Navemar, supra, the State Department having failed to recognize the claimed immunity of the Spanish vessel Navemar, alleged to have been expropriated by and in the possession of the friendly Republic of Spain at the time of her seizure upon a libel in rem, this Court denied the claimed immunity on the ground that the libelled vessel was not shown to have been in the possession and public service of the foreign government.

Republic of Mexico v. Hoffman/Opinion of the Court

The district court was unable to find, under the rule of The Navemar, supra, any ground for relinquishing the jurisdiction over the vessel, and accordingly denied the claim of immunity. The Mexican government then filed an answer to the libel by which it put in issue the material allegations of the libel on the merits and renewed its claim of sovereign immunity from the suit. The court then proceeded with the trial on the merits.

Republic of Mexico v. Hoffman/Opinion of the Court

A second suggestion was then filed by the United States Attorney at the direction of the Attorney General, transmitting a communication from the State Department, stating that it accepted as true the contention that the Baja California was the property of the Mexican government and that it recognized a statement by the Mexican Ambassador that his government would meet any liability decreed against the vessel as a binding international undertaking. The district court denied the claim of immunity, finding that the ship was in 'the possession, operation, and control' of the Compania Mexicana de Navigaction del Pacifico, S. de R.L. This was a privately owned and operated Mexican corporation engaged in the commercial carriage of cargoes for hire for private shippers. On the merits the district court gave judgment for the libellant.

The Circuit Court of Appeals for the Ninth Circuit affirmed, 143 F.2d 854, holding on the authority of The Navemar, supra, and the Katingo Hadjipatera, 2 Cir., 119 F.2d 1022, that the Baja California, although owned by the Mexican government, was not immune from suit because not in its possession and service. We granted certiorari, 323 U.S. 697, 65 S.Ct. 118, on a petition which presented the question whether title of the vessel without possession in the Mexican government is sufficient to call for judicial recognition of the asserted immunity.
