In the village and town of Oohleskill are two banks. In the year 1901 the assessors of that town made their ' assessment against each stockholder of such banks in the manner required by law. The aggregate assessed valúe of such shares of stock of said banks respectively was as follows:
The First Rational Bank of Oohleskill.......... $193,235 08
The Farmers and Merchants’ Bank of Oohleskill.., 65,431 29
Under the provisions of the Tax Law (Laws 1896, chap. 908, art. II, § 24, as amended by Laws 1901, chap. 550, § 2) this assessment of bank, shares was subject to a tax at the rate of 1 per *163centum upon such value. This tax was paid by these banks, respectively, to the treasurer of Schoharie county as follows:
The First Rational Bank..................... $1,932 35
Farmers and Merchants’ Bank................ 654 31
Total tax paid......................... $2,586 6G
Ro question is made as to the regularity or amount of the assessment, but it is claimed by the relator that an erroneous principle was adopted by the board of supervisors in distributing or apportioning this tax among the tax districts entitled thereto.
The board apportioned the tax as follows:
To the county of Schoharie...................■ $568 88
To the village of Oobleskill ............... 1,385 54
To the town of Oobleskill..................... 632 24
$2,586 66
The village and town of Cohleskill refused to receive any part of the sum so apportioned to them, respectively, when" the county' treasurer offered to pay it to them, on the ground that they were entitled to have the whole of the tax refunded and that the county was not entitled to any of it.
The Tax Law, as amended in 1901, section 24, after providing for the method of the assessment and ‘collection of tax on bank shares, contains the following clause: “ The tax hereby imposed shall be distributed in the following manner: The board of supervisors of the several counties shall ascertain the tax rate of each of the several town, city, village, school and other tax districts in their counties, respectively, in which the shares of stock of banks and banking associations shall be taxable, which tax rates shall include the proportion of state and county taxes levied in such districts, respectively, for the year for which the tax is imposed, and the proportion of the tax on bank stock to which each of said districts shall be respectively entitled shall be ascertained by taking such proportion of the tax upon the shares of stock of banks and banking associations, taxable in such districts respectively, under *164the provisions of this act as the tax rate of such tax district shall bear to the aggregate tax rates of all the tax districts in which said shares of stock shall he taxable.”
The provisions above quoted require the tax to be distributed among the tax districts in which the bank shares are taxable. To justify the distribution of a portion of the tax to the county required the board to regard the county as a tax district. This it appears they did, but in so doing I think they fell into an error. The Tax Law (§ 2) defines a “ tax district” to be “ a political subdivision of the state having a board of assessors authorized to assess property therein for state and county taxes.” While a county, like towns and villages, is a political subdivision of the State, it has no board of assessors as do towns and villages and, therefore, it does not come within this statutory definition of a tax district. It was, therefore, unlawful for the board to include the county in its apportionment of this tax and the whole of it should have been apportioned to the town and the village of Cobleskill which were the only “ tax districts ” within which the bank .shares, upon which this tax was paid, were taxable.
It appears that the board ascertained that the tax rate for 1901 of the town of Cobleskill was .0047, and of the village of Cobleskill .0103," making the aggregate tax rates of both tax districts .0150.
Under section 24 of the Tax Law the amount of the bank tax to which each of said tax districts is respectively entitled is such proportion thereof as the tax rate of such tax district shall bear to the aggregate tax rates of all the tax districts in which the shares of stock shall be taxable.
Following this provision of law, it was the duty of the board to apportion the tax on these bank shares, amounting to the sum of $2,586.66, to the town and village of Cobleskill, being the only two districts where the shares were taxable, and the town is entitled to $827.12, or .0047/.0150 thereof, and the village to $1,759.54, or .0103/.0150 thereof.
In ascertaining the tax rate for the payment of county and State taxes it appears that the board did not include in the aggregate equalized valuation of the real estate and the other personal assessments any of the bank stock assessments in the county, which amounted in all to $386,562.93, and by this process made the *165aggregate of real and personal assessments the sum of $12,024,087. The total of State and county taxes being $50,854.52, the tax rate was ascertained to be .004229. If the bank stock assessments had not been eliminated from the total valuations a computation shows that the tax rate would have been reduced to .0040976.
Much attention was given on the argument and briefs of counsel to the question as to which of these methods of ascertaining the rate was correct under the law, counsel for the relator urging that the assessments on bank stocks should be included and for the defendant that they should he excluded.
I do not think, however, that the decision of this question is essential to the determination of the case. Even if an error has been committed by the board in this respect, it cannot be corrected in this proceeding, as it affects all the tax districts of the county, and they are not here as parties.
It is also urged on behalf of the board that in making the apportionment of the bank tax among the districts entitled thereto they were required to exercise judgment and discretion, and having acted, even though erroneously, their acts are not subject to the writ of mandamus. While the law required the board to ascertain the tax rate of the districts entitled to participate in the distribution of the tax, that duty was purely ministerial and not judicial. The rate for the town of Oobleskili, .0047, was known by the board, for they had previously fixed it in levying the taxes against the town. The rate for the village of Goblesltill, .0103, had been officially reported to the board by the treasurer of the village. These rates were existing facts which the hoard had to ascertain. To do so required the exercise of no discretion. When ascertained they had the simple duty, under the law, of adding the rates together and giving to the village tax district and to the town tax district so much of the tax as the tax rate of each district bore to the aggregate tax rates of both tax districts. This again involved the. exercise of no discretion or judgment, but simply a mathematical calculation in which accuracy only was requisite.
To correct the error of law which the board fell into in regarding the county as a tax district, and apportioning a part of the fund to it, I think the relator is entitled to the peremptory writ of mandamus prayed for, but as the board acted under legal advice, and evidently in good faith, the writ should issue without costs.
Ordered accordingly.
