The indictment upon which the defendant was tried, convicted and sentenced was found in the quarter sessions and certified to the oyer and terminer. It contained three counts. *544the first charging burglary, the second larceny, and the third receiving stolen goods, etc. The defendant was convicted and sentenced on the second count.
The record shows that the president judge, having been counsel for the defendant, retired'from the bench, and that the associate judges, “having the Hon. William P. Jenks, a member of the bar of Jefferson county, as amicus curise to advise them as to matters of law,” proceeded to try the case.
The 58th section of the act of April 14, 1834 (P. L. 352), provides that it shall be the duty of the president judge of the court of common pleas, with the associate judges or one of them, to hold the court of oyer and terminer. Other legislation and the constitution of 1874 have conferred the same powers upon the other law judges of the district. The associate judges not learned in the law, or either of them, may open the court and adjourn the same to such day as a quorum of the court can attend, but it is very clear that where the record shows that the president judge is disqualified to sit in the trial of a case by reason of his having been counsel, and the parties do not consent, the associate judges not learned in the law have no authority to try the indictment. Whether written consent filed of record would give them such authority is a question which is not fairly raised by the record in this case.
There is another objection which applies also to a case tried in the quarter sessions at the same term. The record in the latter ease reads as follows: “ Hon. John W. Reed, P. J., having been counsel for defendants, by consent of counsel for Com. and def’ts the case is tried before the two associates, who called the Hon. William P. Jenks to the bench as amicus curise.”
Any infliction of criminal punishment upon an individual except in pursuance of the law of the land is a wrong done to the state, whether the individual assented or not. Consent -is sometimes implied from failure to object; but there can be no waiver of rights by laches in a case where consent would be altogether nugatory. “If,” says Judge Cooley, “the parties cannot confer jurisdiction upon a court by consent, neither can they by consent empower any individual other than the judge of the court to exercise its powers. Judges are chosen in such manner as shall be provided by law; and a stipulation by par*545ties that any other person than the judge shall exercise his functions in their case would be nugatory, even though the judge should vacate his seat for the purposes of the hearing: ” Cooley’s Const. Lim. 492, citing Winchester v. Ayres, 4 Greene (Iowa), 104. We have taken some pains to examine what little there is in the books concerning the functions of an amicus curiae. The curious will find the subject discussed in an interesting manner in 11 Pitts. L. J. (1864) 821.
That term in its ordinary use implies the friendly intervention of counsel to remind the court of some matter of law which has escaped its notice and in regard to which it appears to be in danger of going wrong. It is not ordinarily the function of the amicus curiae to take upon himself the management of a cause as counsel: Taft v. Transportation Co., 56 N. H. 414; Anderson’s Law Dict., nor, we may add, as judge; Some writers say that he may make suggestion of any matters, whether of law or fact: Abbot’s L. Dict.; Black’s L. Dict. We also find cases which, coming before the court ex parte, have been argued by counsel not interested as amici curiae: Ex parte, Yeager, 11 Grat. (Va.) 656. But this is quite a different thing from calling a member of the bar to the bench because the judges being unlearned in the law, do not think themselves qualified to rule upon the questions of law that may arise. No definition of the functions of an amicus curiae that we have been able to find, or that can be sustained by any authoritative decision that has come to our notice, is broad enough to warrant such delegation of judicial power. A judge cannot leave his seat upon the bench and designate a member of the bar, however learned, to take his place; neither can the associates call a member of the bar to the bench to advise them how to conduct the trial and how to decide the questions of law that may arise, and thus virtually take the place of the law judge. To designate such a person as amicus curiae does not alter the case; it is a misuse of the term. It does not disguise the fact that he was called to the bench to exercise judicial functions; and it makes little difference whether he announced the rulings which he advised the judges to make or whether they announced them.
The proceedings do not have even the plea of necessity in their favor. The law has made ample provision for the trial *546of oases in which the law judge of the district is disqualified, from acting, and which the associate judges do not find themselves qualified to try. The act of April 14, 1884, P. L. 333, provides that special courts of common pleas shall be held whenever the president judge shall have been concerned as an attorney or counsel for either party in any suit depending therein; but the parties may agree “ in writing to be filed of record to a trial before such president or before him or any one or more of his associates or before the associates.” These provisions were extended to all cases in the orphans’ court, oyer and terminer or the quarter sessions, by act of April 4, 1843, P. L. 131. “It is extremely doubtful indeed,” says Justice Woodward, "whether even in a court held by them ” (the associates) “ alone, they would be justified in interfering without the consent of the parties with a record made up in a cause where the necessity for a special court had been once judicially ascertained:” Glamorgan Iron Co. v. Snyder, 84 Pa. 397, citing Kolb’s case, 4 W. 154. See also Korman’s Application, 162 Pa. 151. The record in the quarter sessions shows consent of counsel to try the case before the associates, but whether it was in writing and filed of record does not appear in the paper-book. Conceding that it was, the record does not show consent to a trial before the two associates and a member of the bar designated by them, and such consent would be nugatory even if it affirmatively appeared.
To sustain the conviction in either of these cases would establish a most dangerous precedent, and give color of authority for a practice which would be entirely inconsistent with our laws.
Conceding everything that may be urged in favor of the fairness of the trial, and of the ability of the learned gentleman whom the associates called to the bench, the fatal objection is, that a court constituted as this was is not legally constituted, and a conviction had before such a tribunal is not “ by due process of law” or “the law of the land.”
Judgment reversed and venire facias de novo awarded.
