The logs were assessable in the city of Ash-land, if on the 1st day of May, 1903, it was the purpose of the owner to have them sawed at some mill in that city, otherwise they were assessable in the town of Sanborn where they were located. Sec. 1040, Stats. 1898, states that unmistakably in these words:
“Manufacturers’ stock . . . shall be assessed in the district where located. Saw logs and timber which are to be sawed or manufactured in any mill within this state which is owned or leased by the owner of such logs or timber or in which such logs or timber are to be sawed or manufactured by or for the owner thereof shall be assessed as manufacturers’ stock in the district where such mill may be located. . . . No change of location or sale of any personal property after the first day of May in any year shall affect the assessment made in such year.”
The logs were manufacturers’ stock. The principal place of business of the owner in this state was in the town of San-born, in Ashland county. The logs were to be manufactured in this state. Their location on the 1st day of May, 1903, in such town fixed their siius for taxation for such year, unless the same was other than such town by reason of a formed purpose existing on such day to saw them at a mill determined upon elsewhere. No condition created after that day enters into the question of where the property was taxable.
*275It was tbe duty of the assessor in the first instance to determine the proper situs of the property for taxation. His determination thereof, as well as that in respect to the value .of the property, in the controversy before the board of review, was presumptively correct. It could pnly be overturned by some definite evidence impeaching it. The mere fact that his decision was challenged by the property owner by no means cast upon him or the municipality the burden of justifying it. It was the duty of the board to regard such decision as a verity in the absence of definite evidence supporting the allegations in opposition thereto. By no other rule would it be practicable for boards of review to deal with the multitude of protests which might be made before them by property owners. Furthermore, it must be remembered, in dealing with a matter of this sort, that when the decision of a board of review is challenged as not justified by the evidence the real ground of complaint is jurisdictional error, and to constitute such error it must appear that the evidence was so overwhelmingly opposed to the decision that after giving thereto all the weight which it will reasonably bear, keeping in mind that the board has the same advantage over a reviewing tribunal as regards determining the truthfulness of evidence that a trial court possesses, there is no reasonable ground for the decision to rest upon. Where there is evidence tending both ways on a proposition for discussion affording a reasonable opportunity for the exercise of judgment in respect to the matter the board has jurisdiction to act, which means that it has jurisdiction to err as to what is the real right of the matter, and there is no redress for the error, if one is committed, by common-law writ of certiorari, which goes only to jurisdictional errors. State ex rel. Augusta v. Losby, 115 Wis. 57, 90 N. W. 188; State ex rel. Vilas v. Wharton, 117 Wis. 558, 94 N. W. 359; State ex rel. Foster L. Co. v. Williams, 123 Wis. 61, 100 N. W. 1048. So it is not permissible in reviewing the proceedings of a board of review on such a-writ for the *276circuit court to investigate tbe evidence upon wbicb tbe board acted to determine upon wbicb side of tbe controversy it preponderates and to decide accordingly. Its duty is fully performed, except as to tbe rendition of tbe proper judgment, when it proceeds far enough to discover tbat there is a reasonable basis, from tbe standpoint of tbe board, for tbe decision wbicb it rendered. Having reached that conclusion, an affirmance of tbe judgment challenged should follow, though tbe court may yet be of tbe opinion tbat tbe evidence before tbe board clearly preponderated contrary to its finding. Tbe cases to tbat effect decided by this court are numerous and are in tbe main referred to in State ex rel. Foster L. Co. v. Williams, supra.
It' seems probable from tbe record tbat tbe learned trial court did not appreciate tbe principle last discussed, and supposed tbat it was permissible for it to reverse tbe decision of tbe boarS. if merely found to be contrary to tbe clear preponderance of tbe evidence. So recently as tbe time of tbe presentation here of tbe case last cited able counsel insisted tbat such was tbe trend of tbe late decisions of this court. Tbat such was a mistaken and moreover a baseless view of such decisions, we took considerable pains to demonstrate, to tbe end tbat tbe danger might be avoided or removed, if any such danger existed, of tbe trial judge being misled thereby. In tbe record before us tbe learned judge in reversing tbe decision of tbe board used language appropriate to a conclusion tbat it was against the clear preponderance of tbe evidence,, instead of tbat it was wholly unsupported by tbe evidence.
Now on tbe subject of whether on tbe 1st day of May, 1903, tbe owner of tbe logs purposed having them manufactured in the city of Ashland, tbe circumstances very strongly support tbe determination of tbe assessor. It was clearly-shown tbat tbe difficulties in tbe way of transferring tbe logs to tbe owner’s mill in tbe town from where they were located were so great tbat it was highly improbable tbat any such pur*277pose existed. It was shown that within four days after the 1st day of May the logs were put into the water, prepared for transportation, and were actually delivered at the Ashland mill to be manufactured. The work of rafting such a quantity of logs, arranging for their transportation, and actually making the transit from the bank to the mill is so great as to strongly indicate that the purpose to move the logs to Ashland on or prior to the 1st of May must have been formed. It is highly probable that the owner’s agent knew definitely about the matter, yet he refused to testify to any reasonable degree of certainty in respect thereto. Considering all the circumstances from the standpoint of the record alone, we are unable to discover any definite evidence that the purpose of the lumber company was not as early as May 1st formed to have the logs sawed at Ashland. On the contrary, the evidence seems to pretty strongly indicate that such a purpose did then exist. If the fact be otherwise, we are utterly unable to understand why the witness Baker did not squarely say S0j and testify to the existence of circumstances consistent therewith. The board of review was warranted in deciding that there was no reliable evidence to impeach the assessor’s determination. But if that were not so, the trial court was not warranted in concluding that there was no substantial basis for the board’s decision, and that it therefore acted outside of its jurisdiction.
On the question of whether error was committed in reversing the decision of the board as to the valuation of the logs there seems to be less difficulty than as to the one already discussed. As we have already intimated, the learned court seems not to have fully appreciated that only such a departure from the evidence on the part of the board as, under rules governing the subject, constitutes jurisdictional error, was fatal to its decision. Prima facie, as we have seen, the valuation of tbe logs made by the assessor was right. No evidence was produced before the board that the logs on the average were not worth $10 per M. The evidence rather tended to cor-*278robórate than to impeach that. It might well be true that two fifths of the logs were worth $5 per M., and the rest worth enough in excess thereof to make the average price $10 per ]VI. The owner’s agent testified frankly that the pine logs were worth more than that figure, but when pressed to state the full value thereof he declined to do so. That refusal strongly indicates that the valuation by the assessor upon the average was correct. We are unable to see any basis whatever for holding that there was evidence impeaching such valuation so conclusively that the decision upholding it was jurisdictional error.
From the foregoing it follows that the judgment upon the appeal of the plaintiff, the J. 8. Stearns Lumber Company, must be affirmed, and upon the appeal of the city clerk of the city of Ashland it must be reversed, and the cause remanded with directions to enter judgment affirming the decision of the board of review, with costs in favor of such clerk.
By the Court. — So ordered.
