Transatlantic Financing Corporation, the operator of the SS CHRISTOS, entered into a voyage charter with the United States on October 2, 1956, for the carriage of a full cargo of wheat from a United States Gulf port to a safe port in Iran. The charter specified the points of origin and destination but did not indicate the route to be taken.
On July 26, 1956, the Government of Egypt nationalized the Suez Canal Company. During the ensuing international crisis, on October 27, 1956, the SS CHRISTOS sailed from Galveston on a course that would have taken her through the Suez Canal. Israel invaded Egypt on October 29, 1956, followed by invasions of the Suez Canal Zone by Great Britain and France on October 31, 1956. On November 2, 1956, the Egyptian Government closed the Suez Canal to traffic by obstructing it with sunken vessels.
After the closure, Transatlantic's representative contacted an employee of the United States Department of Agriculture on or about November 7, 1956, to request instructions on the cargo and to seek additional compensation for a voyage around the Cape of Good Hope. The ship changed course and arrived in Bandar Shapur, Iran, on December 30, 1956. Transatlantic later filed a libel against the United States in the District Court seeking recovery of the costs attributable to the diversion around the Cape of Good Hope.
The District Court dismissed the libel, and Transatlantic appealed to the United States Court of Appeals for the District of Columbia Circuit.
