In this action of certiorari the trial court, with no return before it, reversed the action of the board of review of Black River Falls. The writ of certiorari, when used as a substantive remedy, is issued for the purpose of removing into court the record of some proceeding had before an inferior court or tribunal, in order that upon, inspection of such record the action taken by the inferior court or tribunal may be judicially reviewed. Black, Law Dict. tit. “ CbetioeaRI.” The court acts upon the record brought before it, and either reverses or affirms the action below, and the only way in which it obtains such record is by way of the return. Logically it cannot pass judgment upon the record until the record is brought before it by means of the return, and such is the holding of the authorities. Walker v. District of Columbia, 6 Mackey, 352; McManus v. McDonough, 4 Ill. App. 180; People v. McCraney, 21 How. Pr. 149.
It is said, however, that the necessity of a return may be waived by the parties, and that in the present case it appears by the recital in the judgment that the respondent •clerk did not desire to answer, and hence that the court was justified in proceeding without a return. The real parties in interest to a legal proceeding may waive many formalities and legal requirements, but in the present case it is manifest that the city clerk, who was a mere formal party, because he was custodian of the record attacked, could waive nothing. The city was the real party in interest on one side, and the taxpayer on the other; and the city has never waived the *285necessity of a return, nor stipulated that the statements of the relation or writ may be taken as true. The case of Rightor v. Gray, 23 Ark. 228, is relied on by the respondent in this court as authority for the proposition that the necessity of a return may be waived. The case, however, is not. authority for the proposition that a mere nominal party,, who is simply the custodian of the record, may waive the necessity of a return. In that case the petition for the writ, was accompanied by a transcript of the record, and the real parties in interest appeared and stipulated that the transcript, attached to the petition should be the return, and waived the issuance of the writ and the making of a formal return. On this state of facts the court said that, although this was irregular practice, the court perhaps acquired jurisdiction of the subject matter thereby. The case is not authority for the course pursued here.
These well-established principles necessitate a reversal of the judgment upon the merits, and the question then arises, whether the writ should not have been quashed.
The board of review is required by law to meet on the-last Monday in June, and the assessor then lays before the board the assessment roll, and all sworn statements as to personal property received by him. Secs. 1060, 1061, Stats. 1898. It appears from the writ that th'e petitioner did not. make any sworn statement of personal property to the assessor while the assessment roll was in his hands, because his sworn statement "was not verified until July 11th — long-after the board of review had commenced their sessions. It. also appears that when the roll was placed before the board the item of $3,000, as the valuation of the petitioner’s personal property, was already upon it. This was then prima facie the correct valuation, and could not be changed except upon evidence. Sec. 1061, Stats. 1898; State ex rel. Giroux v. Lien, 108 Wis. 318.
The appellant contends that the affidavits set forth in the-*286writ were not “ evidence,” within the meaning of tbe statute, while the respondent contends that, having been received by the board of review without objection, they should be considered as evidence. This question is the only one left in the case, and we are not aware that it has been directly passed upon, although there are a number of intimations in the reported cases that “ evidence ” in sec. 1061 means oral evidence. Thus, in Shove v. Manitowoc, 57 Wis. 5, it is said:
“ Thus it appears that the board of review were authorized to increase or lessen the assessment only upon being satisfied from the evidence taken that it was too high or too low. It presupposed a hearing and the examination of some witness or witnesses under oath.”
In State ex rel. Smith v. Gaylord, 73 Wis. 306, it is said: “ The board must act and so decide upon evidence taken before them.” Possibly these intimations in cases where the question is not raised are not of great weight, but, turning to sec. 1061 itself, we think it will bear no other construction. By the terms of the section the board of review are required “ to hear and examine any person or persons upon oath who shall appear before them; ” any person who thinks his property has been assessed too high “ may appear and state to the board under oath ” the true value of his property ; “ any person claiming any correction in the assessment roll may call witnesses to support the same . . . and the attendance of witnesses may be compelled by subpoena;” the board may lower or raise the assessor’s valuation when satisfied “ from the evidence tahen ” that it is too high or too low; and finally the clerk of the board is required to “reduce to writing and preserve the examination and statements of every person and witness taken by the board.” We think there can fie no doubt, from the wording of the section, that it contemplates oral evidence as the only thing upon which the board can act in raising or lowering valuations. One has only to reflect upon the elusive and unsat-*287Isxactory character of an affidavit,— the ease with which in skilful hands it may be made to speak partial truth and mislead the keenest intellect, while stating nothing that is actually untrue,— and then to consider how easily a rigid oral cross-examination would shatter such devices, to be satisfied that the requirement that the testimony taken by the board should be oral is an eminently wise one. Such being the requirement, it is evident that the board cannot waive it, and hence that there was no “ evidence ” before them upon which they were authorized to change the assessor’s valuation.
By the Gourt.— Judgment reversed, and action remanded with directions to quash the writ of certiorari.
