Edward Douglass White, Gulf Railway Company v. Shane…
“ The action of the court below was in violation of this statute. It refused to make up the list of 18, as requested, and confined the right of peremptory challenge to the 12 jurymen called to be sworn, on the ground that such was the custom or rule of practice of the court. Manifestly, the 'rule' or custom of the court could not override the mandatory terms of the statute. That to thus impanel a jury in violation of law, and in such a way as to deprive a party of his right to peremptory challenge, constitutes reversible error, is clear. ”
