Our trial courts are now generally held by a single judge. Until the latter half of the nineteenth century it was not uncommon to have three judges sit together in county or city courts. One of them would be a lawyer and the others not.[See Chap. VIII.] In cities the two side judges were generally aldermen. A tribunal thus constituted is better adapted in some respects to trying questions of fact than a single judge. It is a jury of three acting by a majority. But for the conduct of a jury trial it is unwieldy, slow-moving and uncertain. In most cases any question of law or legal practice will be virtually decided by the presiding judge, but he will usually pause to go through the form of consulting his associates. Occasionally they will overrule him, and in such case it will be apt to be by a misunderstanding or misapplication of law. The expense of three judges, however moderate the compensation, has also weighed in favor of an abandonment of the system. It naturally results in paying too little to the chief judge, and too much to the others; and always costs more than it would to pay one man a sufficient salary.
We have not the need of several judges to hold a trial court, which is felt in many countries. They use them for a purpose which our juries supply. For similar reasons Americans have not seen any occasion for organizing special courts, such as are the German Gewerbegerichte and Kaufmannsgerichte, to try special classes of causes. A jury of twelve will be apt to contain some men who will adequately represent those interested in any ordinary industrial or commercial controversy.
Petty suits not of an equitable nature must generally be brought before a justice of the peace, who disposes of them himself, both as to matters of evidence and fact, but subject to an appeal to a higher court in which a jury trial can be had. In some States he can summon in a jury of six and leave the facts to their determination. The pleadings before him are usually in the same form as in the higher courts.
In jury trials of civil causes the judicial function is, so far as possible, divided into two distinct parts. All questions of pure law are decided by the judge alone. All questions of pure fact are decided by the jury alone. All questions turning on the application of the law to the facts are decided by the jury under instructions from the judge as to what applications of the law it would be competent for them to make under the particular circumstances which they may find to have existed. The judge also has a large discretionary power in minor matters arising in the course of the suit. It is for him to say when it shall be tried; whether the written pleadings are in proper shape, and if not whether they may be amended; and in what order and within what limits the evidence may be introduced.
No countries in the world have so artificial a set of rules of evidence as England and the United States. This is because in no other country is the right to a jury trial so extensive. Many of these rules date back to the early history of the English common law. It was a time of general illiteracy. The ordinary juror could not read or write. His powers of reasoning and discrimination had had little or no cultivation. It was thought dangerous to allow him to listen to any evidence that was not of the clearest and best kind. It was thought necessary to bring all witnesses in person before him and let him hear their voice and look into their faces in order to give him the fullest possible opportunity to determine whether their testimony was worthy of credit. But while our rules of evidence were devised for jury trials, they are applied with equal rigidity in all trials. A jury may be waived; a single judge may hear the cause; and yet he must rule out of consideration whatever would have been inadmissible if it had been made the subject of a jury trial.
Much that in other countries is helpful in reaching a just conclusion is in this manner shut out in American courts. A man of the highest character, for instance, may say before twenty listeners that he saw a certain person shoot and kill another, and state how the whole thing happened. The person thus accused is sued for damages under a statute permitting such a remedy by the representatives of the man shot. Before the trial the witness of the act dies. He was the sole witness. There is no other testimony to be had. Under our system of practice, those to whom the statement was made cannot be allowed to testify to it. Such testimony would be "hearsay." It would put before the jury two questions, first whether such a statement was really made, and then whether, if made, it was true. The law of evidence says that they ought not to be perplexed by questions upon questions.
The tendency of American legislation of late years has been strongly toward removing some of these artificial bars to getting at the truth. The common law thought it dangerous to allow a jury to hear any witness not under oath, nor under such an oath as implied his belief in the existence of a God, or any witness having a pecuniary interest, in the event of the cause. An atheist or an agnostic could not testify. The plaintiff and the defendant could not. These restrictions have been almost everywhere repealed.
The trial judge has also, and necessarily, a large discretionary power in excluding testimony which has only a remote bearing on the case, and in limiting or extending the examination of a witness so as on the one hand to prevent needless repetition, and on the other to get out the truth and nothing but the truth. He has similar authority to restrain the arguments of counsel within reasonable limits.
A trial judge suddenly called upon to make a ruling on some point of law in the progress of a trial may make a wrong one. If so, he may have an opportunity to correct it at a later stage of the proceeding. He has admitted evidence which should have been excluded. In his charge to the jury he may instruct them to disregard it, and his error will thus be cured. He has excluded evidence which should have been admitted. Before the case is closed he can change his ruling and allow it to come in. But so long as any ruling stands unchanged, whether it is in accordance with law or not, it is the law of the case for the purposes of the trial. Counsel may endeavor to procure a reconsideration of the question, but they cannot ask the jury to adopt a different view from that taken by the judge. Their only remedy is by a motion for a new trial, after the verdict, or proceedings in error before a higher court.
