1943-04-05

Headline: Court allows Peru to seek an order blocking a Louisiana maritime suit, finds Peru’s ship immune when State Department certifies immunity and limits private claims in court.

Holding: The Court granted leave to file and held it could, in its discretion, issue the requested writs because Peru had not waived sovereign immunity, so the district court should release the vessel.

Real World Impact:

State Department certification can end U.S. court suits against foreign state vessels.
Private claimants must pursue relief through diplomatic channels once immunity is recognized.
District courts must accept State Department immunity certification and release seized foreign vessels.

Summary

Background

A Cuban company sued a Peruvian steamship, the Ucayali, in a federal admiralty case for failing to carry sugar. The Republic of Peru intervened in the suit, said it owned the ship, filed a $60,000 release bond, took testimony while reserving its claim of sovereign immunity, and asked the State Department to recognize that the vessel was immune from suit. The State Department formally recognized the immunity and the United States Attorney filed that certification in the district court, but the district judge denied release, saying Peru had waived immunity by participating in the case.

Reasoning

The Court first decided it had discretionary power to issue common-law writs (prohibition or mandamus) to district courts in aid of its appellate role and that the case was of public importance because it involved the dignity and rights of a friendly sovereign and foreign relations handled by the political branches. The key legal question was whether Peru had waived its claim of immunity by its actions in the district court. The majority held that Peru had consistently reserved its immunity, that State Department recognition and certification of immunity must be accepted by courts, and that the district court should have released the vessel rather than continue litigation. The Court granted leave to file the petition and indicated the writ could issue on further application.

Real world impact

Foreign states that assert vessel immunity may be protected when the State Department recognizes and certifies that immunity, and courts should defer to that political determination. Private litigants who sue a foreign state’s ship may be sent instead to diplomatic channels when immunity is certified. The decision was procedural here: leave to seek the writ was granted and the Court directed the writ to issue only on further application.

Dissents or concurrances

Justice Frankfurter dissented, arguing the 1925 Act limited direct Supreme Court review and that Peru should have sought relief first from the circuit court of appeals; Justice Roberts simply concurred in the result.
