Noah Haynes Swayne,
Texas v. Chiles (88 U.S. 488)…
“ The first sentence forbids, in the courts of the United States, exclusion in any case on account of color, and in civil actions on account of interest or being a party. If either party offers to testify and is excluded by reason of being a party, there is certainly a clear infraction of the statute, both as to its language and meaning. If either party calls the other, and the party called is excluded upon this ground, is not the infraction equally clear? The language applies as well to one case as to the other. Both are alike within its terms and meaning. We see no ground for a distinction. ”
