Melville Fuller,
Bradford v. Southern Railway Company…
“ Were it not for the words 'prosecute to conclusion,' we doubt if any court would hold that the act applied to an appeal or writ of error in a civil cause. The applicant, by the statute, must declare the nature of his cause of action. Surely an erroneous ruling by the trial court cannot be held to furnish a 'cause of action,' as that phrase is commonly understood. The statute, by that term, in our judgment, refers to a legal demand by one against another, not to the rulings of a trial court. ”
