Justice Frank Murphy once wrote that two aspects of World War II could only be forgotten at our peril. One was the indiscriminate incarceration of Japanese aliens and Japanese Americans. The other was 4 years of martial law in Hawai'i. We have cried “Never Again” to the first but forgotten the second. Therefore, it is at long last that the legal scholars Harry and Jane Scheiber have excavated why and how an unprecedented military rule occurred and how stubbornly it clung to power.
