In 1852, one Gilman built a bridge for the County of Contra Costa, upon a contract for about eight thousand ( dollars, to bear interest at the rate of five per cent per month till paid. The bridge was not completed till some time in 1853. On the 23d of March, 1853, the County of Alameda was created by the Legislature out of territory taken from the Counties of Contra Costa and Santa Clara, and the said bridge fell within the new County of Alameda. The contract for building the bridge being with the County of Contra Costa, and the money being unpaid, Gilman sued that county for the amount due, and in 1856 recovered a judgment for upwards of twenty thousand dollars, with accruing interest and costs. In 1858, the Legislature passed, an Act appointing Commissioners to adjust the amount to be paid by Alameda County,to Contra Costa County, as her share of the debt that had accrued while a portion of Alameda County formed a part of the County of Contra Costa, but the Commissioners in their award were limited by the Act to the indebtedness which had accrued prior to the 23d of March, 1853, the date of the creation of the new county. At that date, no interest on the bridge contract had accrued. The Commissioners awarded ■ against Alameda County the sum of three thousand nine hundred and forty-four dollars and sixty-six cents, but for reasons before stated, the award did not include any interest on the bridge contract. This award was afterwards in 1860 and 1861, paid to the County of Contra Costa. On the 14th of March, 1860, the Legislature passed an Act empowering and requiring the Board of Supervisors of Contra Costa County to levy a special tax for the payment of the judgment, interests and costs recovered by Gilman in 1856 on the bridge contract, which was accordingly done and the judgment paid by the County of Contra Costa.

In 1862, another Act was passed reciting in its preamble the payment by Contra Costa County, in pursuance of said Act of 1860, of the said Gilman judgment of “ thirty-one *647 thousand dollars, some twenty-four thousand dollars of the amount being for interest * * * on an obligation contracted before the organization of Alameda County,” etc., and in the body of the Act appointing Commissioners “ to ascertain and award the amount of indebtedness, if any be found equitably due from the County of Alameda to the County of Contra Costa on account of obligations existing at the time of the organization of the said County of Alameda.” The Commissioners are required, if any award be found against the County of Alameda, to certify the same to the Boards of Supervisors of the respective counties, and thereupon the Board of Supervisors of Alameda County are required, within a specified time, to levy a tax for the purpose, and pay the amount so awarded to the County of Contra Costa. Under this Act the Commissioners awarded in favor of Contra Costa County against the County of Alameda, the sum of eleven thousand five hundred and seventy-four dollars and twelve cents, this sum being for a portion of the said interest paid by the County of Contra Costa on the said bridge contract, and the judgment thereon, and for nothing else. The award having been certified to the Board of Supervisors of Alameda County, and a demand that the tax for its payment be levied in pursuance of the Act having been made, and the said Board having refused to levy the same, an alternative mandamus was issued by the District Court of the Fourth Judicial District against said Board in this case, which was afterwards, by the judgment of the Court made peremptory. From the judgment this appeal is taken.

The appellants make two points—Firstly, the County of Contra Costa has no power to act as relator, for the county is not a party beneficially interested. Secondly, the Legislature has trespassed upon the judicial power.

There is nothing in the first point. The judgment paid was against the County of Contra Costa, and the money awarded is to go into the Treasury of the county. It makes no difference that the law provides that “ it shall be apportioned in the Treasury of the County of Contra Costa,” for certain speci *648 fied purposes, viz: for the construction of certain roads, and to the “ County School Fund.” The county has charge of the funds, and is the trustee appointed by the law to apply it to the public uses specified, all of which are appropriate county charges. The county is, we think, “a party beneficially interested,” within the meaning of the Practice Act.

It is objected that in appointing Commissioners to ascertain and award the amount to be paid by Alameda County to Contra Costa County, the Legislature conferred upon them judicial functions, and thereby usurped powers that, under the Constitution, belong exclusively to the judicial department of the Government. It will be observed that the money claimed was not a legal demand by one county against another, growing out of contracts or transactions between themselves, which could be litigated between them and enforced by suit in a Court of justice. The claim as between the counties arose solely out of legislative action in creating the new County of Alameda in part out of the County of Contra Costa, and wholly independent of the action of either county as between themselves. The Legislature is charged by the Constitution with the power and duty of establishing a system of county and town governments. (Article IX, Section 4.) It may divide counties and create new ones, or change the boundaries, as in its wisdom it may deem the public interest to require. And in creating new counties out of territory taken from counties already organized, it is but just that it should apportion the debts already accrued between the new and old counties in the ratio of the territory, population, taxable property and •benefits conferred on the respective counties, or portions of counties affected by the change. It possesses the taxing power, and the power to determine for what objects of public interest, and to what extent the taxing power shall be exercised. As incident to these powers, it is authorized to apportion the taxes either upon the whole State, or upon particular districts according as the object is one of general or local interest or benefit. It may say what amount shall be paid by one district, and what amount by another.

*649 In the case of The Town of Guilford v. Supervisors of Chenango County, 3 Ker. 149, the Court of Appeals of New York say: “ The Legislature is not confined in its aj>propriation of the public moneys, or of the sums to be raised by taxation in favor of individuals, to cases in which a legal demand exists against the State. It can thus recognize claims founded in equity and justice in the largest sense of these terms, or in gratitude or charity. Independently of express constitutional restrictions, it can make appropriations of money whenever the public well being requires, or will be promoted by it; and it is the judge of what is for the public good. It can, moreover, under the power to levy taxes, apportion the public burdens ^mong all the tax paying citizens of the State, or among those of a particular section or political division.”

This was in a case where certain parties had sued the Town of Guilford for expenses incurred and paid by them in conducting, by direction of the town, certain litigation on the part of the town, but in said suit failed to recover against the town the amount so expended, because the town was not legally liable. Subsequently the Legislature authorized the towm, upon the vote of the majority of the inhabitants, to raise the sum expended and equitably due from the town, by tax, and to pay the demand ; but directing that the decision of the people should be final. The inhabitants voted the proposition down. The Legislature then passed a law authorizing Commissioners to determine and.award the amount expended by the parties in the litigation, and directing the Supervisors of the county to levy a tax upon the Town of Guilford and pay the amount so awarded. The town resisted the tax on the ground that it was unconstitutional, and among other points it was insisted that the Legislature had usurped judicial functions. But the law was upheld. The Court further say in the case, (p. 148): “ The statute book is full, perhaps too full, of laws awarding damages and compensation of various kinds to be paid by the public to individuals who had failed to obtain what they considered equitably due to them by the decision of administrative officers acting under the provisions of *650 former laws. The Courts have no power to supervise or review the doings of the Legislature in such cases.” (See also Blanding v. Burr, 13 Cal. 347 .)

.The Legislature, then, may, in its discretion, determine the objects for which, and the extent to which, the taxing power shall be exercised, and may apportion the taxes to be levied. In ascertaining the amount that ought equitably to be charged upon the different districts, as a guide to the exercise of this discretion, it may pursue its own methods, and employ its own instruments.

In this case the County of Contra Costa, in making a necessary public improvement—a bridge—incurred an obligation, which was chargeable upon the entire county. After the obligation was incurred, but before the entire amount subsequently paid had become due, the county was divided and a large portion of the territory, population and taxable property liable for the demand was, by the Legislature, cut off from the County of Contra Costa, and erected into the new County of Alameda—the new county including the bridge, for the erection of which the obligation was incurred. Equity, at least, required that the Legislature, in making the division of the territory, should tiren, or at some subsequent time, ascertain in some manner, the portion of the debt then accrued or to accrue on existing obligations, that should be equitably apportioned to each of the counties. The Legislature chose to make the apportionment through Commissioners appointed by itself. The amount chargeable upon the whole territory originally liable had, at the time of the passage of the law, been fixed by the judgment of a competent Court, and it was only necessary to make the apportionment. There are two apportionments necessary, firstly, between the two counties, and secondly, each county is to apportion its share among the taxable inhabitants of the county. The latter apportionment as much involves the exercise of judicial functions as the former. Both require an examination of facts, and the exercise of judgment. Both depend upon the same principles, and stand upon the same footing. But neither is in the nature of a suit liti *651 gated between contending parties. The entire amount to be paid is fixed by judgment. The Legislature provides the mode and designates the officers who shall make both apportionments ; and we think the power is peculiarly within the province of the legislative department of the Government. It makes no difference whether each county is directed to levy its proportion of the debt and pay it directly to Gilman, or whether the whole is first raised by the County of Contra Costa and paid to Gilman, and then the County of Alameda raises its portion and pays it to the County of Contra Costa. We think, therefore, the apportionment of the amount to be paid by the respective counties was not an encroachment upon the powers with which the judicial department is charged within the meaning of the Constitution. It is a power that has usually been exercised in other States, as well as heretofore in this State, by the political, and seldom, if ever, by the judicial department of the Government.

The judgment is affirmed.
