I. The issues herein were tried by a jury on demand of the plaintiffs. This is in accordance with sec. 3323, E. S., which provides that, in actions brought under ch. 143 to foreclose liens, any issue of fact therein shall, on demand of either party, be tried by a jury, whose verdict thereon shall be conclusive as in other cases. This court has held that such verdict has the force and effect of a verdict in an an action at law. Willer v. Bergenthal, 50 Wis. 478; Moritz v. Larsen, 70 Wis. 569. It was also held in those cases that an action under ch. 143, in all its essential characteristics, is’ a suit in equity. This ruling has been followed in other cases. Spruhen v. Stout, 52 Wis. 517; Huse v. Washburn, 59 Wis. 416.
It was suggested by counsel that the last case is in con*423flict with Willer, v. Bergenthal and Moritz v. Larsen. An examination of the opinion by Mr. Justice ObtoN in Huse v. Washlmrn will show that the case was decided on the hypothesis that no jury trial was demanded. It was held that, although the court submitted the question of indebtedness to a jury, as it undoubtedly had power to do, the verdict was merely advisory,, all the issues in the action being of equitable cognizance. It seems clear that such must be the result if no jury is demanded. If one is demanded, the issues are to be tried as issues at law. Such is the rule of the above cases, and we perceive no conflict between them.
The learned counsel for the defendants argued that under the construction thus given to sec. 3323, the provision in that section for a jury trial is void, in that it attempts to limit and impair the constitutional powers of a court of equity as respects the trial of issues of fact, and maintain (correctly, no doubt) that in the present case the court did not pass upon the issues but gave judgment upon the verdict alone as in an action at law, whereas (as counsel insisted) the defendants were entitled to the findings of the court upon the proofs as in other equity cases. The cases of Bonesteel v. Bonesteel, 28 Wis. 245, and Anderson v. Case, 28 Wis. 505, are cited to support this position. The cases of Truman v. McCollum, 20 Wis. 360, and Callanan v. Judd, 23 Wis. 343, which were not cited, are more directly in point. In the last two cases a statute which attempted to ingraft upon an action of general equitable cognizance, to wit, an action to foreclose a mortgage, the right to have certain issues therein tried by a jury whose verdict should be conclusive upon the court, was held to contravene the constitutional powers of a court of equity. But we have here no such case.. This action is not one of general equitable cognizance. It is given by ch. 143, E. S., and is purely .statutory. Courts of equity have no jurisdiction to enforce the statutory remedy under the general law alone, and had *424no such jurisdiction when the constitution was adopted, as they had in the cases last cited. Hence those cases do not rule this case. It is competent for the legislature, when it gives a new remedy, to prescribe the procedure by which the remedy may be enforced. It may prescribe a purely equitable or a purely legal procedure, or it may blend the two, as it has done, conditionally, in the statute under consideration. The power to do so cannot be successfully challenged. We conclude that sec. 3323 is a valid law.
II. The plaintiffs failed to obtain the certificates of the architects that they had performed their contract, or of the value of the extra work, or the deduction which should be made from their claim on account of the change of specifications. The contract makes the obtaining of such certificates a condition precedent to the liability of defendants. The cases on this subject, many of them decided by this court, hold this a valid and binding agreement, and that the builder has no right of action under such contract for-jáis materials and labor until he obtains such certificates, unless they are withheld dishonestly and arbitrarily. If so-withheld, all the cases agree that he may recover by showing the fact, and showing also that he has performed the contract according to its terms. The testimony in the present case tends to prove, and the jury found, that the plaintiffs fully performed their contract, and did the extra work as claimed, and that the architects arbitrarily withheld their certificate thereof. The testimony also supports the assessment by the jury of the value of the extra work, and the sum which should be credited to defendants for change of specifications. We cannot properly disturb those findings.
III. Much testimonj' was given on the trial upon the issue whether the defendants had waived the alleged defects in the erection of the building (if there were any) and the production of the architects’ certificates. But since it has been *425determined that the plaintiffs fully performed their contract, and that the certificates thereof were wrongfully withheld, the question of waiver becomes immaterial, and will not be considered.
Several exceptions were taken to the charge given by the judge to the jury. Many, perhaps most of these, relate tp the subject of waiver. Eor the reason just mentioned, these have become immaterial. None of the exceptions to the charge were specifically urged in the argument as grounds for a reversal of the judgment, and it is believed that all of them, except those on the subject of waiver, are practically overruled by the views above expressed. They require no further discussion.
By the Court.— The judgment of the superior court is affirmed.
