Ryan, O. J.
Mere imputation of prejudice to the circuit judge, made in proper time by either party to a civil action, entitles the party making it to a change of the venue. Ch. 123, sec. 8, R. S.; ch. 206 of 1862. With a view, doubtless, of mitigating such inconvenience, ch. 69 of 1870 authorizes the parties to avoid change of the venue on that ground, by stipulating that a member of the bar of this court shall act as judge in the cause, with all the powers and duties of the circuit judge.
- Such a statute might work well. But we cannot consider *392it competent under tbe constitution. That instrument vests all judicial jurisdiction in courts and justices of tbe peace, and provides for tbe election of judges of all courts; and tbe legislature can confer none on other officers or persons, excepting power not exceeding tbat of a circuit judge at chambers, on certain officers now called court® commissioners. Att'y Gen. v. McDonald, 3 Wis., 805; Gough v. Dorsey, 27 id., 119; Conroe v. Bull, 7 id., 408. So manifest is this intent to distribute and restrict tbe exercise of judicial authority by express grant, tbat tbe framers of tbe constitution deemed it necessary to give express authority to tbe judge of one circuit to bold court in another. Tbe statute in question was well intended, but obviously overlooked tbe constitutional restriction. It seems too manifest for discussion tbat, under tbe constitution, no one can bold a circuit court but a circuit judge. Certainly not a court commissioner', who can only act as circuit judge at chambers. A fortiori, not one bolding no judicial office: a gentleman of tbe bar assuming no judicial office, but merely chosen by tbe parties to an action to act as a sort of judicial arbitrator in it. If tbe statute before us could be upheld, we do not see why one could not which should assume to give to tbe parties, in all actions, in all courts, power to stipulate tbe judges off tbe bench, and private persons into their seats. Judicial power is one of the attributes of sovereignty, necessarily delegated in its exercise. Tbe constitution does not leave tbe delegation loose at tbe discretion of tbe legislature. It delegates tbe judicial power to constitutional courts, to be held by constitutional judges. And these constitutional judges take no power from tbe constitution, can take none from tbe legislature, to subdelegate their judicial functions. See tbe instructive case on this subject of Cohen v. Hoff, 3 Brevard, 500.
Tbe respondent petitioned tbe court below, representing tbe judge to be related to tbe parties and necessarily and insensibly prejudiced in tbe case, but not praying change of tbe *393venue. We give no opinion whether the petition properly raised the question of prejudice. The learned judge himself evidently thought that it did.
The parties thereupon filed a stipulation that Mr. Cole, a member of the bar of this court, should act as judge on the trial of the cause; and the court below made an order, reciting the petition for prejudice, and ordering the cause to he tried before Mr. Cole as judge of the court, in accordance with the statute.
The trial appears to have taken place before Mr. Cole and a jury, who found for the respondent. There is in the record what purports to be a bill of exceptions and an order refusing a new trial, signed by Mr. Cole. The judgment is signed by the clerk, with a statement at its head that Mr. Cole sat as judge on the trial.
We cannot look into the bill of exceptions or consider the order denying a new trial, because both are unofficial and devoid of judicial authority. They are as any other irrelevant papers finding their way by accident or mistake into the record of a cause. And the only question for us is, whether we should hold the judgment supported by a presumption that it rests upon a proper trial of the issue, or should consider it as rendered by Mr. Cole, and therefore not properly the judgment of the court below.
We cannot doubt that the latter is the proper view. All judgments are by the consideration of the court. Judieia in deliber ationibus matmrescu/nt. The judicial mind goes to all judgments, either by particular consideration or by general consideration established by rule. There must be actual or constructive consideration of the judge of the court. Judi-cmm est quasi jv/ris dictum. And it is the voice of the judge 'only which is the voice of the law. Judex est lex loquens. And we cannot close our eyes to the truth so patent in this record, that, in compliance with the statute before us, the learned judge of the court below abdicated his judicial office *394and function, for tbis canse, in favor of Mr. Cole. And it was by consideration of Mr. Cole, not of tbe circuit judge, tbat tbis judgment went. Indeed, with tbe suggestion uncontro-verted tbat tbe judge was related to tbe parties, we do not see bow be could well sit in tbe cause, E. S., cli. 123, sec. I. Be tbat as it may, tbe record discloses tbat be left tbe bench and Mr. Cole toot bis place upon it, assumed bis duties in tbe cause, and tided it; and tbat upon Mr. Cole’s quasi judicial consideration and voice only, tbis judgment was rendered. It was literally coram non judice.
Tbis pbrase is commonly applied directly to tbe court itself. But it applies, in its proper sense, to a court not having jurisdiction of a matter, pnly because tbe judge is, quoad hoc, not a judge. And tbe judge de jure et de facto of a court not having jurisdiction of a cause in it, is, for tbat cause, like a private person assuming to exercise judicial functions over it. “ When tbe court has not jurisdiction of tbe cause, there tbe whole proceeding is coram non judice, .... and therefore tbe said rule .... qui jussio judicii aViquod fecerit (but when be has no jurisdiction, non est judex) non videtur dolo malo fecisse, quia qqarere necesse est, was well allowed, but it is not of necessity to obey him who is not judge of the cause, no more than it is a mere stranger, for tbe rule is, judicúum a non suo judice datum nullvas est momenhi.” Marshalsea case, 10 Rep., 68 b, 76 a; cited and approved in Taylor v. Clemson, 2 Ad. & E., N. S., 978. “ It is tbe same as though there was no court. It is coram non judice.” Grumon v. Raymond, 1 Conn., 40. So, because tbe jurisdiction of a court can be exercised only by tbe judge defacto of tbe court, tbe judge of a court not having jurisdiction is likened to a stranger assuming to exercise tbe jurisdiction of a court having it; tbe proceeding in both cases being coram non judice. Tbe rule as given in Fleta, following Bracton, appplies very closely to tbisjcase. It is there said, in substance, tbat no one can proceed judicially to whom regular jurisdiction has not *395been delegated, by the king bimself; and that no other can control the power of the county or punish for contempt (contumacy) except one on whom judicial power has been conferred, not by a judge, but by the king himself, for that even a praetor could not substitute judges under him, because the judgments of such would be of no effect. Sententia enim a nonjudice lata nemimi débet nocere. Fleta, book 6, ch. 6., secs. 6, 7. So, we are told by Coke that even when the king personally sat in the King’s Bench, “the judicature only be-longeth to the judges of that court;” and that they “have supreme authority, the king himself sitting there as the law intends.” And he calls them sovereign justices. 4 Inst,, 73. If the king himself, sitting in his own court, held coram ipso rege, could not exercise its judicial power, surely no private subject of his could. “Judicium is derived ajtvre et dido, et est quasi jv/ris dictum ” (3 Inst., 210); and it is only the appointed judge who can speak the authoritative word of the law. Mr. Oole might pronounce the law as well as any of us; it is not that he wanted ability, but that he wanted authority. His voice could not utter jwris dAcPivm, quia non est judex. “ He was not judge de jure or de facto, and therefore all Iris acts-as such are void.” Frame v. Trebble, 1 J. J. Marsh., 205. See Broom’s Leg. Max., 69.
There is a quaint relish of poetry in the way of putting the sovereign delegation of judicial function in Martin v. Marshall, Hob., 63. “All kingdoms in their constitution are with the power of justice, both according to the rule of law and equity; both which, being in the king as sovereign, were after settled in several courts; as the light, being first made by God, was after settled in the great bodies, the sun and *396moon. But that part of equity being opposite to regular law, and in a manner an arbitrary disposition, is still administered by tbe king bimself and bis chancellor, in bis name ab initio, as a special trust committed to tbe king, and not by bim to be committed to any other. ” With all deference to that great judge, it might perhaps be suggested that here is a slight inaccuracy of constitutional law, celestial and terrestrial. For there does not appear to be any radical distinction in the delegation of equitable jurisdiction and of legal jurisdiction. Equity never rested in mere discretion of king or chancellor. And it is certainly contrary to the received notion, that the moon shines as a luminary per se, like the sun. Taking the sun and moon- according to the common acceptation, and following Hobart’s metaphor, the circuit judge might be likened to the sun of the court below, in this cause, and Mr. Cole to the moon, after the fashion of a juridical depute in Scot’s law, shining with delegated jurisdiction. But the constitution mars the comparison. For by the astronomical constitution the sun appears to take power to delegate his functions of lighting the world; while the state constitution tolerates no such delegation, and appoints a sun only, without any moon, as luminary of the circuit court, whose “ gladsome light of jurisprudence ” must be sunshine only, not moonshine. Commissioners, masters, referees, and like judicial subordinates, may share in judicial labor and lighten it; but they cannot change places with the judge on the bench or share in the final judgments of the court.
We do not forget that this court has upheld the judgments of judges de facto, not de jure, in Re Boyle, 9 Wis., 264; State v. Bloom, 17 id., 521; Laver v. McGlachlin, 28 id., 364. But in all these cases the person acting as judge held the office under color of title. So the court says in Re Boyle: “ Every person assuming to exercise the authority of an officer, does not thereby necessarily make himself an officer de facto. But when it appears that the person exercising the powers of *397an office, is in by such a color of right, and that he has such possession of the office, as makes him an officer de facto, then his acts as to third persons are valid, and his right to hold the office can only be inquired into in some direct proceeding for that purpose.” Here, Mr. Cole was not in possession of the office of judge, and did not claim it. He only accepted a delegation of its functions jyro hac mice, acting for the circuit judge in some sort as a judex pedaneus of the Roman law. And those cases are quite in accord with this.
The judgment plainly proceeded upon a mistrial, which cannot support it; and the judgment itself is plainly not a proper judgment of the court below. "Whether void or voidable, it should be reversed. Sayles v. Davis, 20 Wis., 302; Hays v. Lewis, 21 id., 663.
By the Court. — The judgment of the court below is reversed, and the cause remanded for trial according to law.
