William R. Day,
Waters-Pierce Oil Company v. Texas…
“ The argument to the effect that the rulings of the court as to the admission of testimony, and upon questions of general law, deprived the defendant of its property and rights without due process of law, requires us to notice the limitations upon the authority of this court when dealing with legislative acts and proceedings to enforce the same in the state courts. That state legislatures have the right to deal with the subject-matter and to prevent unlawful combinations to prevent competition and in restraint of trade, and to prohibit and punish monopolies, is not open to question. ”
