Appellate courts are of many kinds. Some are such exclusively; some mainly. In others the functions of entertaining appeals is a minor one, most of their time being occupied in trying original causes. An appeal from judgments of a justice of the peace, for instance, is generally given on the merits to county courts, but the greater part of the litigation before them comes there in the first instance. So the judgments of county or other minor courts are often reviewable on appeal for errors in law in some superior court which, like them, is principally occupied in the exercise of an original jurisdiction.

When the American colonies passed into States, as has been seen, they were habituated to the thought of a supreme controlling authority exercised by one tribunal of a judicial character of last resort. The judicial committee of the Privy Council had administered this sovereign power for them, and for a long period of years, with general acquiescence.[Footnote: See Chap. I.] The uniformity of result thus obtained was acknowledged to be advantageous. It was now necessary to replace them by American courts of last resort, and it was not difficult in doing so to improve upon the English model. The time had come for separating, as far as it could conveniently be accomplished, judicial from political power.

Virginia was the first to act. A few days before the Declaration of Independence she adopted a Constitution (under which the government, was carried on until 1830, though it was never formally submitted to or ratified by the people) providing for a separate judiciary headed by a Supreme Court of Appeals whose judges should hold office during good behavior, and be ineligible to the Privy Council or General Assembly.

This divorce of judiciary and legislature was not the plan universally followed.

New Jersey, in which as a colony the Governor and Council had possessed an appellate power like that vested in the English House of Lords, was so well satisfied with this arrangement as to continue it in her Constitution of July 3, 1776, and up to the present time puts upon her Supreme Court a certain number of judges who give but a part of their time to this work, and are not necessarily (though in practice of late years they generally have been) lawyers.

New York, in her Constitution of 1777, pursued a somewhat similar plan. Her highest court was one "for the trials of impeachments and the correction of errors." Its members were the Senate with the Chancellor and judges of the Supreme Court. When a judgment of that court was brought up for review the judges were to state their reasons for giving it, but had no vote. This scheme was adhered to with little modification until 1846. What made it tolerable was that many of those elected Senators were naturally lawyers, and that to be in the Senate soon became the ambition of a lawyer with any desire to know how it would feel to be a judge. Able and learned opinions were pronounced by such men in exercising their judicial functions, and some of them in the New York reports are still frequently the subject of reference as clear and satisfactory statements of legal principles.

Connecticut, in 1784, when she instituted for the first time a court of last resort, made it up of the Lieutenant Governor and the twelve Assistants, and soon added to it the Governor himself. A plan of this kind was likely to work in that State, as in New York, better than it looked. Lawyers by this time had come to fill most of the higher offices of state. Although the Assistants were elected annually it was under a complicated scheme of nomination, which, unless in case of a political revolution, ensured re-election in every case. A majority of the Assistants were always members of the bar. They were also Federalists from the beginning of party divisions in the country. Naturally, the Republicans found such a state of things intolerable. All the power of government in Connecticut, said one of those who were celebrating Jefferson's second election to the Presidency in 1804, "together with a complete control of elections, are in the hands of seven lawyers who have gained a seat at the council board. These seven men virtually make and repeal laws as they please, appoint all the Judges, plead before those Judges, and constitute themselves a Supreme Court of Errors to decide in the last resort on the laws of their own making. To crown this absurdity, they have repealed a law which prohibited them to plead before the very court of which they are Judges." Attacks like this were too just to be resisted, and two years later the Governor, Lieutenant-Governor and Assistants were replaced by the Judges of the Superior Court.

Constitutional provisions that the right of trial by jury shall be preserved inviolate preclude, as a general rule, the establishment of courts in which the judges can make a final disposition of petty causes which turn on disputed facts. An appeal from their decision must be allowed, and a new hearing given on the merits in a court furnished with a jury. Under the Constitution of the United States a trial by jury cannot be claimed in civil cases at common law involving a demand of not over twenty dollars, and in most of the older States it cannot be in cases where it was not a matter of right prior to the adoption of their Constitutions.

The verdict of a jury can only be reviewed on its merits by a court of last resort where it was clearly and palpably against the weight of evidence, and in order to do this the whole evidence given in the trial court must be certified up.

Where a judgment has been rendered on a finding of facts made by a judge in a cause of an equitable nature, this finding can, in the courts of the United States and in many of the States, be reversed on any point on appeal. For this purpose also all the evidence that was before him, or all that is pertinent to questions involved, must be reported to the court above.
