After World War I, the Allied Powers under Article XXII of the Covenant of the League of Nations designated Great Britain mandatary of Palestine, providing inter alia that, as far as possible without prejudice to the rights of the then residents of Palestine, steps were to be taken to facilitate Jewish immigration. A High Commissioner for Palestine was appointed, who, by the authority vested in him under the mandate, promulgated a general ordinance regulating immigration. It was provided therein that any British government ship might board any vessel to detain and examine persons reasonably believed to be seeking to enter the country in violation of this regulation. It was further provided that the master of a vessel attempting to bring such persons into the country would be guilty of the criminal offense of abetting illegal immigration and that the ship used for such purpose would be forfeited. If no criminal proceedings were instituted against the master, forfeiture might be confirmed by petition of the Attorney General to a district court of Palestine.
