A decision on a point of law by the highest court in a State does not, however, bind its lower courts as absolutely as would a statute. An inferior court may disregard it and decide the same point another way if it be fully satisfied that the action taken by the court above was ill-considered and erroneous. It is possible that in such event, on reconsideration, the court of last resort may reverse its original position.[Footnote: A good instance of this is furnished by the case of Johnson v. People, 140 Illinois Reports, 350; 29 Northeastern Reporter, 895. In McFarland v. People, 72 Illinois Reports, 368, the Supreme Court had stated in its opinion, that if two unimpeached witnesses gave the only testimony as to a certain point material to the plaintiff's case, and testified in contradiction of each other, the case failed for want of proof. Many years later a charge to the jury to this effect was asked and refused in an inferior court. An appeal was taken to the Supreme Court, and there Mr. Justice Schofield, the author of the original opinion, thus disposed of it: "Although in McFarland v. People, 72 III., 368, the writer of this opinion expressed the belief that a similar instruction was free of legal objection, his remarks in that respect were unnecessary to a determination of the case then before the court, and they were made without sufficient consideration, and are manifestly inaccurate. They are now overruled. The question of competency is one of law, and therefore for the court; but the question of credibility,—that is, of worthiness of belief,—and therefore the effect of the competent evidence of each witness, is one of fact, and for the jury.">[ If not, that acquires by this attack a double force.

Chief Justice Bleckley of Georgia once remarked that courts of last resort lived by correcting the errors of others and adhering to their own. Nevertheless, they have often, years after formally announcing a certain legal doctrine in one of their opinions, declared it to be unsound, and overruled the case in which it was laid down. They do this, however, with natural and proper reluctance, and never if this doctrine is one affecting private rights of property and has been followed for so long a course of time that it may be considered as a rule on which the people have relied in exchanging values and transferring titles.

The public, however, have rights to be regarded as fully as individuals, and if a right of private ownership has been adjudged to exist, which involves a public loss, the precedent thus created might be overruled with less hesitation than one would be determining rights and correlative obligations that were purely private. Thus the North Carolina courts for seventy years held that a public office was the private property of the incumbent. No other courts in the United States took that view, and it has, by a recent decision, been repudiated in North Carolina.[Footnote: Mial v. Ellington, 134 North Carolina Reports, 131; 46 Southeastern Reporter, 961; 65 Lawyers' Reports Annotated, 697.]

Still more are public interests to be regarded when a question arises as to reversing a decision as to the proper construction of a constitutional provision. If a judicial mistake be made in construing a statute it is easily remedied. The next legislature can amend the law. But a Constitution can only be amended with extreme difficulty and by a slow process. If the court falls into error as to its meaning, the correction must ordinarily come from its own action or not at all. Hence an opinion on a matter of constitutional construction is less to be regarded as a final and conclusive precedent than one rendered on a matter of mere private right.

It has been the position of some American statesmen and jurists that judicial decisions on points of constitutional construction were not binding upon the executive or legislative department of the government. President Jackson asserted this with great force in his message to the Senate of July 10, 1832, disapproving the re-charter of the Bank of the United States. He conceded, however, that a judicial precedent may be conclusive when it has received the settled acquiescence of the people and the States. But while such acquiescence may strengthen the authority of a decision, it can hardly be regarded as that which gives it authority. That comes from the fact that it is an exercise of the judicial power of the government in a case for the disposal of which this judicial power has been properly invoked.

The decision of the court in McCulloch v. Maryland[Footnote: 4 Wheaton's Reports, 316. See Willoughby, "The American Constitutional System," 44, 123.] unquestionably settled forever, as between the cashier of the bank and the State of Maryland, that the bank was a lawful institution. That in Osborn v. The Bank of the United States[Footnote: 9 Wheaton's Reports, 738.] reaffirmed it as between the bank and the Treasurer of the State of Ohio. It would be intolerable if such judgments were not in effect equally conclusive for the determination of all controversies between all men and all States growing out of the creation of such a corporation. Practically, then, the opinion of the executive department to the contrary could only be of importance in such a case as Jackson had in hand; that is, in its influencing executive action in approving or disapproving some proposed measure of legislation. It could not disturb the past.

The authority of a judicial precedent is weakened if it comes from a divided court, and especially if a dissenting opinion is filed in behalf of the minority. A silent dissent indicates that the judge from whom it proceeds is not so impressed by the fact, or the importance to the public, of what he deems the error of the majority that he thinks it worth while to express the reasons which lead him to differ from them.

No departure from precedent in any American court has ever awakened so much feeling as that by the Supreme Court of the United States in 1872, when it decided that Congress could make government notes a legal tender for debts contracted before the law was passed.[Footnote: The Legal Tender Cases, 12 Wallace's Reports, 457, 529.] It had held precisely the contrary two years before,[Footnote: Hepburn v. Griswold, 8 Wallace's Reports, 603.] but it was by a bare majority and in the face of a strong dissenting opinion. In the opinions filed in the second case stress was laid upon this division of the court.[Footnote: 12 Wallace's Reports, 553, 569. See George F. Hoar, "Autobiography," I, 286.]

The word "established" is often used to describe the kind of precedent to which courts are bound to adhere. What serves to establish one? Long popular usage, repeated judicial affirmations, and general recognition by approved writers on legal topics. Of these, in fact, the last is probably the most powerful. Lawyers and courts, in countries without codes, get their law mainly from the standard text-books. Such authors as Coke, Blackstone, Kent and Cooley are freely cited and relied on as authorities by the highest tribunals.[Footnote: See, for instance, Western Union Telegraph Co. v. Call Publishing Co., 181 United States Reports, 101; Louisville Ferry Co. v. Kentucky, 188 United States Reports, 394, 397.] It is by the writings of such men that judicial precedents are sifted and legal doctrines finally clothed in appropriate terms and arranged in scientific order.

The English courts long ago declared it to be a rule of law to prevent perpetuities that no estate in lands could be created which was not to commence within the compass of a life or lives of persons then existing, with an exception intended to favor a minor heir. American courts accepted this rule, but some of them construed it as meaning that no estate in lands could be created which was to continue after the expiration of such a period. This construction was shown by Professor John C. Gray, in a work on "Perpetuities," to be unwarranted, and since its publication the cases which had proceeded on that basis have been generally treated as erroneous.
