The appellant, a resident taxpayer of Ada county, appealed to the district court from the following order made by the board of county commissioners:
“Wheeeas, It appears to this board of county commissioners that the maximum amount of eighty cents on one thousand dollars on the assessable property in Ada County, which can be levied for road purposes for the fiscal year beginning on the second Monday in January, 1910, will yield approximately the sum of $8,000.00; and,
“Whereas, It appears that during the fiscal year beginning on the second Monday in January, 1910, it will be necessary for this board of county commissioners in keeping the public highways within said Ada County in repair and in a safe condition for public travel to expend not less than the sum of $20,000.00; and,
“Whereas, It appears that the amount of money that can be raised by levying the maximum rate provided for by law for road purposes will be entirely insufficient to keep the public highways of Ada County in repair and in a safe condition for public travel, and that it will be necessary for this board to cause to be transferred from the current expense fund *152of said Ada County to the road fund the sum of at least $12,000.00 for road purposes;
“Now, THEREFORE, be It Resolved, That for the purpose of providing sufficient finances to keep the roads and bridges of Ada County, State of Idaho, in repair and in a safe condition for public travel during the fiscal year beginning on the second Monday in January, 1910, the amount of $12,000.00, be, and the same is hereby transferred from the current expense fund of said Ada County for said fiscal year for the-county road fund for said year. The said sum of $12,000.00, so transferred to the county road fund to be used to meet the necessary cost and expenses of constructing, maintaining- and repairing roads and bridges during the said fiscal year.
“And be it further resolved, That a special tax not to exceed one-half of one per cent on the taxable property of said Ada County be levied annually until the said amount of $12,000.00 so transferred from the current expense fund to-the county road fund is raised and paid.”
The cause was tried in the district court and the order of the board of county commissioners was sustained and affirmed. From that judgment this appeal was taken. It is contended by appellant that the board of county commissioners had no-authority to make the order appealed from, for the reason-that such order was made by reason of the provisions of an act approved Mar. 16, 1909 (Laws of 1909, p. 274), commonly known as “The Good Roads Law,” which act is inoperative- and void.
It may be conceded that if what is known as “The Good' Roads Law” is void, then the county commissioners had no-authority to enter the order appealed from and the same should be annulled and set aside. Referring to this act it will be observed that two methods are provided for raising-revenue for road purposes; the first is by levying a road tax which shall not exceed eighty cents on each one thousand dollars of the assessed valuation of the property taken from the-assessment-roll for the preceding year; the second, by issuing bonds of the county upon a two-thirds vote of the electors of the county, and the creation of special taxing districts extend*153ing along the course of a road or highway, and by levying a special tax upon the lands within' said district to pay such proportion of such bonded indebtedness as the board may de- termine. The second method thus provided for is embraced in the provisions of see. 21 of this act, and it is the contention of appellant that this section is so indefinite, uncertain and incapable of execution that it is void, and because such section is void the entire act is void. By the provisions of this section it no doubt was the intention of the legislature to provide a method by which, when bonds were authorized to-be issued by a vote of the electors of the county for the purpose of constructing or improving a particular line of road or a bridge, the cost of constructing or improving such road should be partly assumed and paid by the county as a whole, and partly assumed and paid by a taxing district, including certain lands especially benefited by the construction of such road. After providing for the method of voting bonds said section provides: “And in addition may provide for the creation of a special taxing district; extending along the course of such road, or highway; such taxing or assessment district shall consist of the land and property which shall abut such highway, when it shall have been constructed, and all other-lands near by, which, in the judgment of the commissioners, will be especially benefited by such highway. Such special taxing or assessment district shall be subject and liable to such proportion of the indebtedness created by such bond issue, and in such degree as the board shall designate in such resolution, and such bonds shall constitute a lien on all taxable property therein, as to such proportion so designated by the-board of county commissioners. The board shall direct the road supervisor to prepare a map, to be filed with the clerk of the board, showing the tracts of land therein included, and the assessed owners thereof, and giving the definite boundaries, of such district with reference to the legal subdivisions, which, map shall be incorporated by reference into the resolution authorizing the bond issue. And such boundaries, and the land included therein, shall thereafter constitute such special, taxing or assessment district.”
*154It will be observed that this section provides for the creation of a special taxing district, and that such district shall be subject and liable to such proportion of the indebtedness created by such bond issue and in such degree as the board shall designate in such resolution; and such bonds shall constitute a lien on all taxable property therein. There is no provision, however, made in said section which requires or makes it the duty of the board of county commissioners to levy a special tax to discharge such lien. No method is provided for or designated as to the manner of levying this tax or the collection of the same, and no machinery is outlined for carrying into execution the levying or collecting of the special tax to be levied against the lands within said taxing district. It is impossible to determine how the special tax shall be levied or distributed, and how or in what manner it shall be collected or by whom, or what shall be done with the money to be thus collected. In other words, the section standing alone fails to provide any machinery for carrying into execution the provisions with reference to the special tax to be levied in the taxing district. This is the only section found in the act which deals with the subject of assessment districts or the levying of a special tax within such district. If bonds, therefore, were voted by the county, there is no method provided for paying the proportion of the indebtedness created by such bond issue, designated to be paid by the taxing district, in the order or resolution of the board authorizing a vote to be taken as to the issuance of such bonds. It requires no extended argument to prove that this section provides no means for its execution. A casual reading of such section is sufficient proof.
It was conceded upon the argument by counsel for respondent, as well as special counsel who presented' a brief upon behalf of the good roads- association as amicus curiae, that such is a fact. But it is argued by counsel for respondent and also by counsel for the “Ada County Good Roads Association” that even though sec. 21 be void, still it is the duty of the court not to -declare the statute as a whole void unless the nullity and invalidity are beyond reasonable doubt. This *155is now the settled law of this state. (Gillesby v. Board of Commrs., 17 Ida. 586, 107 Pac. 71.)
It is also settled in this state that if the provisions of an act are connected in subject matter, dependent on each other, and designed to operate for the same purpose, or are otherwise so dependent in meaning that it cannot be presumed that the legislature would have passed one without the other, then if one part falls the entire act must fall. (Ballentine v. Willey, 3 Ida. 496, 95 Am. St. 17, 31 Pac. 994; Knight v. Trigg, 16 Ida. 256, 100 Pac. 1060; Gillesby v. Board of Commrs., 17 Ida. 586, 107 Pac. 71.) If, therefore, taking this statute as a whole, it clearly appears that see. 2Í was considered and recognized by the legislature as an important and integral part thereof, and so connected in subject matter with other provisions of the act, and other provisions were so dependent upon sec. 21, that it cannot be presumed that the legislature would have passed said act with such section omitted, then the entire act must fall.
Under the road law as it existed prior to the adoption of the act now under consideration, the board of county commissioners were authorized to levy a tax for road purposes of not less than ten nor exceeding sixty cents on each one hundred dollars of valuation. Under the good roads law now under consideration, the board is authorized to levy a tax for road purposes to not exceed eighty cents on each one thousand dollars of valuation. There must have been some reason for this decided and great reduction in the general levy the board were authorized to make, and an examination of sec. 21 clearly discloses such reason. This section provides for the creation of special taxing districts, and authorizes the issuance of bonds upon a vote of the electors of the county for the construction of roads and bridges within such district and the levying of a special tax within said district to aid in paying such bonds.
The legislature no doubt were of the opinion that the creation of special taxing districts and the issuing of bonds as provided by this section would make it unnecessary to authorize the board of commissioners to levy so high a tax for general road purposes. In other words, the general levy was *156reduced in contemplation of the bond issue and the creation of the special taxing districts, and see. 21 is intended to supplement see. 20, each depending upon the other, and so connected that if sec. 21 falls the purpose of the legislature in-enacting said good road law has been defeated. These two-sections were clearly designed by the legislature to operate-for the same purpose, that is, to provide the method of creating a fund for the construction and maintenance of the roads of the county. In our opinion, these two sections are so dependent in meaning that it clearly appears that the legislature-would not have passed one without the other. If these two-sections, are obliterated, then the act has no force whatever, because no provision is left for raising funds for road work.
It is, however, argued by counsel for respondent that although see. 21 is void, yet the remainder of the act should be upheld, because Rev. Codes, see. 937, provides means by which sufficient funds can- be covered into the road fund to supply the loss occasioned by reason of the defeat of the bond proposition. This section among other things provides r “Whenever it appears to the board of county commissioners that the road fund is or would be unreasonably burdened by the expense of constructing, or of maintaining and repairing, any bridge or road, .... the said board! may, in its discretion, cause a portion of such cost or expense to be paid out of the current expense fund of the county, and may levy a-, special tax” to pay the same.
This, however, does not answer the contention that sec. 21 of the good roads law is an essential part thereof, and was an inducement which led the legislature to enact such law, because if that be true, then the entire act must fall and the-provisions of Rev. Codes, sec. 937, cannot save the law. This •section was intended as an emergency provision, and authorizes the board of county commissioners to cause a portion of' the cost of constructing, maintaining and repairing any bridge or road to be paid out of the current expense fund when the-road fund would be unreasonably burdened by such expense. The emergency, however, contemplated by this section was such as arises by reason of destruction or injury to roads o.r-*157bridges previously constructed. It was not intended to authorize the transfer of funds from the current expense fund to the road fund for the purpose of creating a sufficient road fund to inaugurate a new plan or system of constructing or building roads throughout the county. Neither was it intended that the board should be authorized to make such transfer to replace funds lost to the road fund by reason of inoperative or void1 acts of the legislature. "When this section was enacted the legislature certainly did not anticipate that the road fund of the county would be burdened on account of the legislature passing inoperative or void acts affecting the means and method of providing a road fund, but rather had in mind emergencies which might arise out of the action of the elements in destroying or injuring roads or bridges. It was clearly within the power of the legislature to authorize the board of commissioners to levy a higher rate of taxes for general road purposes, and the legislature has the constitutional power to determine the extent of such levy. The mere fact that the levy provided by the legislature will not raise a sufficient amount of money to keep the roads of the county in that state of repair in which the board of commissioners believe they should be kept, would not be a reason why the board of commissioners could draw upon the current expense fund, and was not the emergency contemplated by the provisions of sec. 937, supra.
We have carefully examined the act involved in this case with a view of giving it effect, as it appears to have been the intention and desire of the legislature in enacting such statute to provide means for better roads, but we cannot do so without trespassing upon the powers of the legislature. As said by the court in State v. Pairflow, 91 N. C. 550, 49 Am. Rep. 652:
“A statute must be capable of construction and interpretation ; otherwise, it will be inoperative and void. The court must use every authorized means to ascertain and give it an intelligible meaning; but if, after such effort, it is found to be impossible to solve the doubt and dispel the obscurity, if no judicial certainty can be settled upon as to the meaning, *158the court is not at liberty to supply — to make — one. The court may not allow conjectural interpretation to usurp the place of judicial exposition. There must be a competent and efficient expression of the legislative will. ’ ’
And as was said by the supreme court of Montana in Hilburn v. St. Paul, M. & M. Ry. Co., 23 Mont. 229, 58 Pac. 551: “So, if an act of the legislature is so vague and uncertain in its terms as to convey no meaning, or if the means 'for carrying out its provisions are not adequate or effective, or if it is so conflicting and inconsistent in its provisions that it cannot be executed, it is incumbent upon the courts to declare it void and inoperative.” (State v. West Side St. Ry. Co., 146 Mo. 155, 47 S. W. 959; 1 Lewis’ Sutherland, Stat. Const., see. 86.)
From what has been said it follows that the judgment of the district court is reversed. Costs awarded to appellant.
