The Sao Vicente

Background

George S. Duarte described himself as the Consul General of Portugal and asked the Supreme Court to review several lawsuits. Lower courts handled separate cases: in rem suits to recover for materials and labor furnished to steamers called The Sao Vicente and The Murmugao, and in personam suits against Transportes Maritimos do Estado related to services for The Cunene and The Santo Antao. Transportes Maritimos intervened, claimed ownership, and asserted that the vessels and operations were those of a Portuguese government department and not subject to U.S. suits. The trial court rejected that defense, and appeals focused on whether the courts had jurisdiction.

Reasoning

The central question was whether the Consul General, merely because of his office, could appear here to assert his government’s immunity. The Court held he could not. Relying on earlier decisions, the opinion explained that a consul’s ordinary role is commercial and that a consul is not automatically a diplomatic agent authorized to vindicate sovereign prerogatives. The Court found no proof that Portugal had specially authorized the Consul General to act on its behalf in this way. Because the Consul General was not a party in the lower proceedings and lacked special delegation, the Court concluded the request for review was improvidently granted and dismissed it.

Real world impact

The ruling restricts a consul’s ability to step into U.S. courts and claim a foreign government’s immunity without explicit authorization. It leaves the underlying maritime claims and the lower courts’ jurisdictional rulings in place. Foreign governments wishing to assert immunity must provide clear, special authorization for their agents to act in U.S. litigation.
