Customary international law exempts small unarmed fishing vessels from capture as prizes of war in the absence of contrary directives.
Professor Notes

In The Paquete Habana, the Supreme Court addressed the interplay between custom international law and U.S. domestic law regarding maritime captures during wartime. The case highlights the principle that customary international law can prevail in U.S. courts when there is no existing statute or executive directive to the contrary. The Court emphasized that principles of humanity dictate the treatment of unarmed vessels, particularly those engaged in innocuous fishing activities, thus supporting the broader notion of international humanitarian law.

Additionally, the ruling underscored the importance of adhering to the customary norms recognized by civilized nations at the turn of the 20th century. This case is significant not only for its legal precedent but also for its demonstration of the United States' commitment to international law during a time of conflict, influencing how future courts handle similar dilemmas pertaining to war and trade.
