Ozawa v. United States,
260 U.S. 178 (1922)

¢We have been furnished with elaborate briefs in which the meaning of the words 'white person' is discussed with ability and at length, both from the standpoint of judicial decision and from that of the science of ethnology. It does not seem to us necessary, however, to follow counsel in their extensive researches in these fields. It is sufficient to note the fact that these decisions are, in substance, to the effect that the words import a racial and not an individual test, and with this conclusion, fortified as it is by reason and authority, we entirely agree.
