The question is simply this: can a Negro whose ancestors were imported into this country and sold as slaves, become a member of the political community formed and brought into existence by the Constitution of the United States, and as such become entitled to all the rights, and privileges, and immunities, guaranteed by that instrument to the citizen. One of these rights is the privilege of suing in a court of the United States in the cases specified in the Constitution.
