Ozawa v. United States,
260 U.S. 178 (1922)
¢Beginning with [In re Ah Yup], the federal and state courts, in an almost unbroken line, have held that the words ‘white person’ were meant to indicate only a person of what is popularly known as the Caucasian race. . . . With the conclusion reached in these several decisions we see no reason to differ. . . .  The determination that the words ‘white person’ are synonymous with the words ‘a person of the Caucasian race’ simplifies the problem, although it does not entirely dispose of it. Controversies have arisen and will no doubt arise again in respect of the proper classification of individuals in border line cases. The appellant, in the case now under consideration, however, is clearly of a race which is not Caucasian. . .
