Duncan v. Kahanamoku
Case Date: 05/04/2025
Duncan v. Kahanamoku, 327 U.S. 304 (1946), was a decision by the United States Supreme Court. It is often associated with the Japanese exclusion cases (Hirabayashi v. United States, Korematsu v. United States and Ex parte Endo) because it involved wartime curtailment of fundamental civil liberties under the aegis of military authority.[1]
While Duke Kahanamoku was a military police officer during World War II, he arrested Duncan for public intoxication. At the time, Hawaii, not yet a state, was being administered under the Hawaiian Organic Act which effectively instituted martial law on the island. Duncan was therefore tried by a military tribunal and appealed to the Supreme Court. The court ruled that trial by military tribunal was, in this case, unconstitutional.
