(2.) It leads to monstrous tyranny by putting the Property, Liberty, and Life of every man at the mercy of the government officers, who determine the Law and its Application, leaving for the jury only the bare question of Fact, which the judge can so manage in many cases as to ruin most virtuous and deserving men.
(3.) Not only in ancient times did the jury decide the three questions of Fact, of Law, and of its special Application, but in cases of great magnitude they continue to do so now, in both America and England, and sometimes in direct contradiction to the commands of the judges.
Gentlemen of the Jury, if you perform this threefold function, then you see the exceeding value of this mode of trial,
1. For the punishment of wrong deeds done against the law, done by the unorganized selfishness of thieves, housebreakers, murderers, and other workers of unrighteousness;
2. And also for the prevention of wrong deeds attempted in the name of law, by the organized selfishness of the makers and officers thereof.
For in each special case brought to trial, the jury are judges of the Law and of its Application. They cannot make a law—statute or custom—nor repeal one; but in each particular case they must demand or forbid its execution. These Tribunes of the Saxon People have no general veto on law-making, and can efface no letter from the statute-book, but have a special and imperative veto on each case for the Application of the law.
Justice, the point common to the interests of all men, yes, the point common to God and our Conscience, is the Aim and Purpose of Law in general; if it be not that the law is so far unnatural, immoral, and of no obligation on the conscience of any man. The special Statute, Custom, or Decision, is a provisional Means to that end; if just, a moral means and adequate in kind; if unjust, an immoral means, inadequate in kind, and fit only to defeat the attainment of that Justice which is the Purpose of all Law. Accordingly, if by an accident, a special statute is so made that its application in a particular case would do injustice and so defeat the Design and Purpose of Law itself, then the function of the jury under their oath requires them to preserve the End of law by refusing to apply the provisional statute to an unjust use. And if by design a statute is made in order to do injustice to any man—as it has very often happened in England as well as America,—then the jury will accomplish their function by refusing to apply that statute to any particular case. So will they fulfil their official oath, and conserve the great ultimate Purpose of Law itself.
Gentlemen, you will ask me where shall the jury find the Rule of Right, and how know what is just, what not? In your own Conscience, Gentlemen; not in the conscience of the Attorney for the Plaintiff-Government, or the accused Defendant; not in the conscience of the community; still less in the technical "opinion" of the lawyers, or the ambition, the venality, the personal or purchased rage of the court. Of course you will get such help as you can find from judges, attorneys, and the public itself, but then decide as you must decide—each man in the light of his own conscience, under the terrible and beautiful eyes of God. How does the juror judge of the Credibility of Evidence? By the "opinion" of the lawyers on either side? by the judge's "opinion," or that of the community? No one would dare determine thus. He decides personally by his own common sense, not vicariously by another's opinion. And as you decide the Matter of Fact by your own Discretion of Intellect, so will you decide the Matter of Right by your own Discretion of Conscience.
Gentlemen, when the jury do their official duty it becomes impossible to execute a statute, or custom, or to enforce a decision which the jury—"the country"—think unjust and not fit to be applied.
