Answer:
On the basis of the fact that they were loyal citizens of America.
Explanation:
Mitsuye Endo an American citizen of Japanese origin was among the other Japanese citizens taken to relocation camps after the Pearl Harbor attack by Japanese forces in December, 1941. Endo contested her detention by a writ of habeas corpus. She stated that her liberty was taken away from her even though she was a law-abiding citizen of the United States.
When the matter got to the supreme court in 1944, Justice William O. Douglas stated in his opinion of the court that the War Relocation Authority was exceeding its boundaries by detaining citizens who were concededly loyal to the United States.
