In the two cases first above stated, quo warranto proceedings were brought by the Attorney General of the State, the purpose being to test the validity of Chapter 11905, Acts of 1927.
For the same purpose an injunction was sought in the circuit court in the third case by a citizen tax payer of the *119State, to restrain the State Comptroller from drawing warrants upon the State Treasurer under the provisions of Chapter 11905, Acts of 1927. Motions to quash and demurrers were filed in the quo warranto eases, and an appeal was taken from a temporary injunction granted by the circuit judge in the third case.
The statute is as follows:
“CHAPTER 11905 — (No. 100).

*126“Sec. 11. This Act- shall take effect immediately on its becoming' a law.
“Approved May 25, 1927.”
The Constitution of the State contains the following:
“Each law enacted in the legislature shall embrace but one subject and matter properly connected therewith, which subject shall be briefly expressed in the title.” Sec. 16, Art. III.
The legislature shall provide for raising revenue sufficient to defray the expenses of the State for each fiscal year’, and also a sufficient sum to pay the principal and interest of the existing indebtedness of the State.” Sec. 2, Art. IX.
“No money shall be drawn from the treasury except in pursuance of appropriations made by law.” See. 4, Art. IX.
“The legislature shall have power to provide for issuing State bonds only for the purpose of repelling invasion or suppressing insurrection, or for the purpose of redeeming or refunding bonds already issued, at a lower rate of interest.” Sec. 6, Art. IX.
It is within the province of the legislature to purchase property for the State; and this function may, within appropriate limitations, be exercised through governmental administrative agencies. But an unlimited authority to-purchase property for the State may be an unlawful attempt to delegate the legislative power. While discretionary authority within proper limitations to purchase property for the State may be conferred upon State agencies, subject to audit or approval by proper officers; yet such authority may not be delegated without definite limitations, as by attempting to confer upon individuals, without statutory limit and without supervision, revision, consideration, approval of audit by any responsible official, authority to *127fix the price to be paid for property purchased by or for the State.
The power to appropriate State funds for a lawful State purpose is legislative, and may be exercised only through a duly enacted statute. Appropriations of State funds that are made by law can be used only for the payment of claims against the State that are duly authorized and are audited and approved according to law. The legislative powers to purchase property for the State and to make appropriations in payment of purchases, can lawfully be exercised only in the manner contemplated by the Constitution. Unlawful delegations of the legislative power are ineffectual; and in appropriate proceedings, an invalid attempt to delegate legislative power or an enactment that violates organic law, may be adjudged by the courts, whereupon the Constitution by its superior force renders the enactment inoperative.
By express terms, Chapter 119’05, Acts of 1927,- authorizes three engineers to be designated, one each by the State Road Department, the owners of the highway and the Governor; and such such “Board of Engineers,” not being officials, are required to “make a survey and examination of” the highway and to prepare and file verified triplicate detailed statements, certifying, in their judgment, an estimate of what it would cost the State to reproduce, at prevailing prices, said highway as now constructed, giving due consideration to the present condition of said highway. If the engineers fail to agree, the agreement of any two of them shall be considered the report required to be made on which report a binding obligation of the State is sought to be predicated. Whether this authority conferred upon the engineers and its resultant effect make the engineers officers of the State or not, the Act attempts to confer unlimited authority upon “any two” of the engineers, one of *128whom is designated by the owner of the highway, to estimate not the value of the highway but what it would cost to reproduce the highway at prevailing prices, the State to be bound to purchase at the price so estimated, without definite appropriation or limitation and without examination, approval or audit by any official. This is clearly an unlawful attempt to delegate legislative power in that no limitation is placed upon the authority sought to be conferred'upon the non-official engineers to fix as an estimate, not predicated upon value, the amount of money that is to be paid from the State Treasury. Besides this the Act provides that upon the report of the engineers filed with the Comptroller stating the amount agreed on by “any two” of the engineers, the Comptroller shall upon proper transfer of the highway to the State, draw and deliver to the sellers or their assigns a warrant drawn on the State Treasury for the first payment of the purchase price of the highway. Other stated annual payments, plus interest from the date of the first warrant, are provided to be made by warrants drawn by the Comptroller on the State Treasury. And finally ‘‘ on the first day of February, 1932, said Comptroller shall draw and deliver to the proper party or parties, a sixth warrant, against said fund above mentioned, payable to the proper party or parties, and his, its, or their assigns, for the remainder unpaid on the purchase -price of said highway plus interest on said sum at not to exceed five per centum per annum from the date of said first warrant issued hereunder to the date of said sixth and last warrant.”
The amount of the last payment is without any limit whatever except that it is to “be and is hereby appropriated out of any funds in the State Treasury set aside during the year of 1932, for the use of the State Road Depart*129ment, or its successor, for the construction or maintenance of roads and highways in the State of Florida. ’ ’
This attempt to confer upon non-official engineers unlimited authority to fix by estimate the amount that shall be paid from the State Treasury without audit or approval by any responsible official, is inoperative because it violates the intent of Section 4, Acticle IX, Constitution. See 185 N. W. 72.
The Act also provides that any sum or sums to become due for the purchase of the highways by the State may be assigned by instrument in writing, “and upon proper instrument of assignment being filed with the Comptroller of the State of Florida, and approved by the Attorney General of the State of Florida, said Comptroller is hereby authorized and empowered to make said warrants, or any one of them, payable to the assignee thereof and deliver such warrant or warrants so assigned to said assignee.”
The peculiar terms of the Act and the proceedings sought to be authorized by it would in effect create a binding continuing interest bearing contract obligation of the State to pay money in the future that would violate the intent of Section 6, Article IX of the Constitution. See Advisory Opinion to the Governor filed Nov. 23, 1927, 114 Sou. Rep. 850.
As Chapter 11905, Acts of 1927, is in essential respects repugnant to applicable provisions of the Constitution, the enactment is inoperative. The demurrers and motions to quash in the quo warranto proceedings are overruled and the order appealed from in the injunction suit is affirmed.
It is so ordered.
