"The inquiry of course here is, Does the amendment as to the particular standard which this heading embraces involve the mere refusal to comply with the commands of the Fifteenth Amendment as previously stated?...The provision is this:
"But no person who was, on January 1, 1866, or at any time prior thereto, entitled to vote under any form of government, or who at that time resided
in some foreign nation, and no lineal descendant of such person, shall be denied the right to register and vote because of his inability to so read and
write sections of such constitution."
We have difficulty in finding words to more clearly demonstrate the conviction we entertain that this standard has the characteristics which the
Government attributes to it than does the mere statement of the text. It is true it contains no express words of an exclusion from the standard which
it establishes of any person on account of race, color, or previous condition of servitude prohibited by the Fifteenth Amendment, but the standard
itself inherently brings that result into existence since it is based purely upon a period of time before the enactment of the Fifteenth Amendment and
makes that period the controlling and dominant test of the right of suffrage."
