Opinion by

Plaintiff, owner of certain lots m the city of Tulsa, sought to enjoin their sale for nonpayment of certain sewer assessments. He attacks the law (chapter 15, art. 16, Comp. Laws 1909) under wmch the proceedings relating to the construction of the sewer were had and unuer which the contract therefor was let as unconstitutional upon the ground that It provides for assessment by area rather than directly according to the peculiar benefits derived by the abutting property. The (question was fully determined against the plaintiff’s contention in City of Perry v. Davis & Lounger, 18 Okla. 427, 90 Pac. 865, and again, in Lonsinger v. Ponca City, 27 Okla. 397, 112 Pae. 1006. It is so held by the Supreme. Court of the United States in a long line of cases of which French v. Barber Asphalt Pav. Co., 181 U. S. 324, 21 Sup. Ct. 625, 45. L Ed. 879, is a notable example.

The second ground is that no notice was given to property owners as provided in section 468, Rev. Laws 1910. Counsel overlooks. *152 the fact that, though these statutes are called “Laws of 1910” they were never in force in this state until May, 1913 (Laws 1913, c. 75, p. 116), after the contract here involved had been let, and consequently the notice provided in section 468, supra, could not have been here given, as the proceedings had already reached a stage later than that prescribed for giving such notice. The original act did not contain this provision for notice, and was valid without it. Perry v. Davis & Younger, supra; Lonsinger v. Ponca City, supra.

It is finally contended that the amount paid the contractor exceeded the engineer’s estimate. This element of the petition • is barred by the 60-day statute of limitation prescribed in section 992, Oomp. Laws 1909 (section 471, Rev. Laws 1910). It is true we held in regard to paving that if the contract entered into exceeded the estimate, such contract was void. Morrow v. Barber Asphalt Paving Co., 27 Okla. 247, 111 Pac. 19S, and in thé same ease followed by Shultz v. Ritterbusch, 38 Okla. 478, 134 Pac. 961, and others, held that this statute of limitations applied to irregularities, but not to jurisdictional defects, which rendered the proceedings void. But here the allegation is not that the contract entered into exceeded the estimate, but that the payments made to the contractor exceeded the estimate. Section 990, Oomp. Laws 1909, provides in part:

“As soon as any district sewer shall have been completed, the city engineer or other officer having charge of the work shall compute the whole cost thereof, which shall also include all other expenses incurred by the city in addition to "the contract price of the work, and shall apportion the same against all the. lots or pieces of ground in such district exclusive of improvements. ⅜ * * ”

This section seems to contemplate that other items exceeding the estimate may properly be charged against the property as a .part of the assessment. However that may be, since there is no allegation, that the contract exceeds the estimate, any overpayment thereon could not affect the jurisdiction to make the improvement, or to levy an assessment to pay the same, hut would constitute merely an irregularity. Shultz v. Ritter-busch, supra. Such irregularity must be attacked within the 60-day period prescribed in the statute. We find no merit in the plaintiff’s petition, nor in the action of the trial court in sustaining a demurrer to it.

The judgment should be affirmed.

By the Court: It is so ordered.
