WASHINGTON(UP) --Attorneys-generals of California, Oregon and Washington Monday joined in a brief filed with the supreme court asking that restrictions against Japanese-American citizens in Pacific coastal areas be removed "as soon as national security permits."

The brief was filed in the case of Fred T. Korematsu, California-born Japanese, who has appealed from a conviction for violating military requirements during the army's 1942 evacuation of Japanese-Americans from the west coast.

"This court has emphasized that except in the most unusual circumstances, racial discriminations are prohibited," the brief stated. "The restrictions placed upon this group of our citizens must be removed as soon as the military authorities are determined that the national security permits."

The brief was entered by the states as friends of the court. Oral arguments in Korematsu's appeal are scheduled to be heard by the court this week."
