(after stating the facts). It is first insisted that the bill increasing the twenty per cent, limitation on the cost of the improvement is unconstitutional because, after being passed by one house, the bill was .transferred to the other branch of the Legislature on the same day and read twice there.
This court has decided adversely to the contention of plaintiff in Reitzammer v. Desha Road Imp. Dist. No. 2, 139 Ark. 168. In that case the court held that .under our Constitution a bill can not be read more than *41twice in either house on one day; but that after it has passed one house it may be carried to the other house on the same day and read the first and second times there, provided the rules be suspended as required by the Constitution.
Section 1 of the act passed at the special session of /the Legislature of 1920 provides that the commissioners of the two improvement districts above referred to are authorized to proceed with the work of constructing the improvement, although the cost thereof in each improvement shall exceed twenty per cent, of the assessed value yof the real property in the district. Special Act 39, approved January 26, 1920.
Counsel for the plaintiff contend that this provision iof the statute is unconstitutional and in that contention jve think counsel are correct.
1 Article 19, section 27 of the Constitution provides that nothing in this Constitution shall be so construed as to prohibit the General Assembly from authorizing assessments on real property for local improvements in town or cities under such regulations as may be prescribed by law, to be based upon the consent of a majority in value of the property holders owning property adjoining the locality to be affected. This section of the Constitution was complied with in organizing the district, and a majority in value, of the owners of real property within the proposed district in each case signed the petition asking for the construction of the improvement. At that time section 5683 of Kirby’s Digest was in force. It provides that no single improvement shall be undertaken which alone will exceed in cost twenty per cent, of the value of the real property in such districts as shown by the last county assessment.
According to the allegations of the complaint the cost of the improvement in each district will exceed the twenty per cent, allowed by the statute.
From the provision of our Constitution set out above it is apparent that local improvements in cities and towns *42must be based upon tbe consent of a majority in value of tbe owners of real property in the proposed improvement district. Tbe foundation of tbe improvement is tbe petition of the owners of real property situated in tbe proposed district. Tbe Legislature passed statutes for tbe purpose of carrying into effect tbe provision of the Constitution just referred to. One provision of tbe statute is that no single improvement shall be undertaken which \alone will exceed in cost twenty per centum of tbe value of the real property in such districts as shown by tbe county assessments. Kirby’s Digest, § 5683. This section was in force at tbe time tbe original petition in each of these districts was signed. It was evidently tbe intention of tbe framers of tbe Constitution that tbe petition when signed by tbe property owners must be considered with reference to tbe statutes then existing for tbe purpose of carrying into effect tbe Constitution. Otherwise a majority of tbe owners of real property might sign a petition thinking that tbe amount of taxation they would have to pay for tbe improvement was limited by tbe existing laws and tbe Legislature, might afterward materially increase their burden of taxation. This principle was recognized in Deane v. Moore, 112 Ark. 254. In that case it was held that an amendatory act to tbe effect that tbe interest on tbe money borrowed by tbe improvement district should not be computed as a part of tbe cost of an improvement in so far as it related to tbe limit of twenty per centum. Tbe court said that to give tbe amendatory statute that effect would be to impose an additional burden upon tbe property owners without obtaining their consent as required by tbe Constitution. It is claimed that this language was not necessary to a decision of that case. Strictly speaking, this is true, but the language used was a part'of tbe reasoning of tbe court, and in any event it states a sound principle of law. When tbe.consent of the, property owners was first obtained, tbe petition signed by them should have been construed with reference to tbe existing laws on tbe subject. If tbe laws *43carrying into effect the provision of the Constitution are ^subsequently changed so as to increase the burden of the taxpayers, a new petition must be filed as required by the Constitution. Of course, the statute might be amended in regard to the details of carrying out the improvement, but an additional burden can not be imposed upon the citizens by increasing the tax limit without getting up a new petition and obtaining a majority in value of the owners of real property in the proposed district. This principle was also recognized in Bell v. Phillips, 116 Ark. 167, and Sembler v. Water & Light Imp. Dist., 1091 Ark. 90.
Counsel for the improvement district rely upon the case of Faver v. Wayne, 134 Ark. 31, where the court held that the Legislature could by special act remove the thirty per cent, limitation provided in the Alexander Road Law as the limitation to be expended upon improvements undertaken under that act. The Alexander Road Law is purely a creature of the statute, and the Legislature in the first instance might have dispensed with the requirement that a majority in numbers, acreage, or value, of the owners of real property in the district should sign the petition for the creation of the district. Having the power to dispense with the requirement in the first instance, the Legislature might dispense with the requirement by a subsequent statute. Here the Constitution provides that a majority in value of the owners of real property within- the proposed district shall sign the petition before the improvement can be undertaken. The petition must be considered with reference to the existing laws, and no subsequent act can add to the per cent, of taxation to be paid by the property owners without again obtaining their consent to the petition.
To sustain their contention, counsel for the improvement district also rely on sections 4 and 5 of Special Act No. 39, approved January 26, 1920. Section 4 reads as follows:
“Any local improvement district that may hereafter be organized in the city of Morrilton may expend any sum necessary to complete the improvement in the district, not *44in excess of the assessment of benefits, and such district shall not be limited in cost of improvements to twenty per cent of the assessed valuation of the real property in the district.”
Section 5 provides that if any part of the act is held to be invalid it shall not affect the remainder of the act.
Counsel for the improvement district contend that, even if section 1 of Special Act 39' is held to be unconstitutional, it may be stricken out without impairing the effect of the remainder of the act, because sections 1 and 4 are wholly independent, and section 5 provides that if any part of the act shall be held invalid, it shall not affect the remainder of the act. The contention of counsel is'correct. This.court has held that the unconstitutional portion of a statute may be stricken out without impairing the effect of the remainder of the act where the provisions are wholly independent, and it can be seen that the Legislature would have enacted the remaining part of the statute. Snetzer v. Gregg, 129 Ark. 542, and Heinemann v. Sweatt, 130 Ark. 70. This does not help counsel under the facts as disclosed by the record. Section 4, by its terms, is prospective in its operation and cannot apply to a district organized before its passage. It is clearly and manifestly repugnant to section 5683 of Kirby’s Digest, which provides that no .single improvement shall be undertaken which alone will exceed in cost twenty per centum of the value of the real property in such district as shown by the last county assessment. The special act raises the limitation of the cost of the improvement. The special act, being a later act, operates necessarily to en-graft upon the prior and general statute a modification to the extent that the city of Morrilton in improvement districts organized after the passage of the special act may exceed the twenty per cent, limitation provided in the general act and to that extent was intended as a substitute for the general act so far as improvement districts thereafter organized in the city of Morrilton are concerned. 36 Cyc. 1093; 25 R. C. L., sec. 178, p. 929; Walla Walla City v. Walla Walla Water Co., 172 U. S. 1; United *45 States v. Matthews, 173 U. S. 381, and State v. Cosgrove (Neb.), 26 L. R. A. (N. S.) 207.
This section, however, cannot apply to the present case because the proceedings for the organization of the district were commenced before the statute was passed.
,It follows that the court erred in sustaining a demurrer to the complaint, and for that error the decree will be reversed and the cause remanded with directions to the chancery court to grant the prayer of the complaint.
