delivered the opinion.
In the year 1895 the Portland University was the owner of a tract of land containing two hundred and fifty and one third acres, and the college buildings thereof, all which it is alleged was used and occupied for the purposes of the institution. The assessor of Multnomah County assessed all said tract to the plaintiff, and so returned the same upon the assessment roll to the board of equalization. Application was made to the board by petition, praying that said lands be stricken from the roll as exempt from taxation upon the ground that it was the property of a literary institution within the state, and actually occupied for the purposes for which it was incorporated. The board refused the prayer of the petition in toto, whereupon the plaintiff applied to the county court for the same relief, and the court struck from the roll sixty-seven and ninety-two one-hundreth acres of said tract as exempt from assessment and taxation, and refused to disturb the assessor’s return as to the balance. From this action of the court the plaintiff prosecuted a writ of review to the circuit court, and, the writ having been there dismissed, it has appealed to this court.
1. It is contended that the county court has the power to correct the assessment roll by striking therefrom all the lands of plaintiff as exempt from assessment and taxation, and that such power is derived
2. This view necessarily affirms the judgment of the court, below, but the respondent insists that the action of the board of equalization touching the exemption claimed is final, and conclusive upon the petitioner. Whether such board had power to act in the premises depends entirely upon the interpretation of sections 2778, 2779, Hill’s Ann. Laws. By these sections boards of equalization are authorized “to examine and correct the assessment rolls of their respective counties, and to increase or reduce the valuation of property assessed, in the manner hereinafter provided,” which is as follows: “If it shall appear to such board of equalization that there are any lands or other property assessed twice, or in the name of a person or persons not the owner thereof, or assessed under or beyond its actual value, or any lands, lots, or other property not assessed, said board shall make the proper corrections.” Statutes conferring powers of the nature here under consideration are always to be strictly construed, and it is well settled that such powers can be exercised only when expressly or by necessary implication conferred by statute. To recapitulate, the board is empowered to increase or reduce valuations; to correct the assessment if property is assessed more than once, or in the name of a person not the owner; and to add to the roll property omitted by the assessor. In the enumeration of these powers we find none authorizing the board to determine whether property is exempt from assessment and taxation, or
3. Touching the assessor’s authority, it appears that he has no jurisdiction to assess land or other property exempt from assessment and taxation, and his action in the premises in determining that it is not used or occupied so as to bring it within the exemption is not conclusive, the fact being one on which jurisdiction depends. The question as to whether property is assessable under the statute is jurisdictional, and therefore open to inquiry, whenever the authority to make an assessment is asserted, notwithstanding the assessor has exercised his judgment thereon: McLean v. Jephson, 123 N. Y. 143 (9 L. R. A. 493, 25 N. E. 409); In re New York Catholic Protectory, 77 N. Y. 342; Illinois Central Railroad Company v. Hodges, 113
