The same principles apply to civil cases as to criminal. If a jury consent, at the dictation of the court, as to either law or evidence, to render a verdict, on the strength of which they have reason to believe that a man's property will be taken from him and given to another, against their own notions of justice, they make themselves morally responsible for the wrong. Every man, therefore, ought to refuse to sit in a jury, and to take the oath of a juror, unless the form of the oath be such as to allow him to use his own judgment, on every part of the case, free of all dictation whatsoever, and to hold in his own hand a veto upon any verdict that can be rendered against a defendant, and any sentence that can be inflicted upon him, even if he be guilty. Of course, no man can rightfully take an oath as juror, to try a case "according to law," (if by law be meant anything other than his own ideas of justice,) nor "according to the law and the evidence, _as they shall be given him_." Nor can he rightfully take an oath even to try a case "_according to the evidence_," because in all cases he may have good reason to believe that a party has been unable to produce all the evidence legitimately entitled to be received. The only oath which it would seem that a man can rightfully take as juror, in either a civil or criminal case, is, that he "will try the case _according to his conscience_." Of course, the form may admit of variation, but this should be the substance. Such, we have seen, were the ancient common law oaths. CHAPTER XI. AUTHORITY OF MAGNA CARTA. Probably no political compact between king and people was ever entered into in a manner to settle more authoritatively the fundamental law of a nation, than was Magna Carta. Probably no people were ever more united and resolute in demanding from their king a definite and unambiguous acknowledgment of their rights and liberties, than were the English at that time. Probably no king was ever more completely stripped of all power to maintain his throne, and at the same time resist the demands of his people, than was John on the 15th day of June, 1215. Probably no king ever consented, more deliberately or explicitly, to hold his throne subject to specific and enumerated limitations upon his power, than did John when he put his seal to the Great Charter of the Liberties of England. And if any political compact between king and people was ever valid to settle the liberties of the people, or to limit the power of the crown, that compact is now to be found in Magna Carta. If, therefore, the constitutional authority of Magna Carta had rested solely upon the compact of John with his people, that authority would have been entitled to stand forever as the supreme law of the land, unless revoked by the will of the people themselves.
