Ladd, J.
The plaintiff has owned and resided on lots 1 'and 2, in block 38, of Havnon & Le Valley’s addition to the city of Waverly, since 1887. The ends of the lots .abut on Market street, lot 1 lying along Linn street. Tn 1882 he planted eight elm trees along the east side of lot 1 between the board walk and the curb line, and these trees are now twenty-five or thirty feet high. and ten to fourteen inches in diameter. In 1887 a cement sidewalk replaced the board walk, and in 1894 the city by ordinance established the grade of the streets therein, and among other things ordained that the roadway in Linn street be thirty-four feet wide, seventeen feet on each side from the «enter to the curb line. In 1889 the entire street was brought down to grade, except that part between the curb line and lot 1 and a like tract across the way. The plaintiff put in curbing, and a driveway from the street was cut down. The portion undisturbed was from twenty-three to thirty inches above the grade, so that he placed two large stones as steps next to the alley at the south to enable pedestrians to reach his cement walk and built a retaining wall along the alley line to the curbing. At %he other end there was a plank approach. We understand that the parcel of ground between the curb and *747street line across from lot 1 has been reduced to grade, so that the strip in front of plaintiff’s premises is all that remains above the established grade. The elm trees had been planted with the approval of the city, and the record bears evidence of plaintiff’s persistent insistency upon their preservation. On June 3,' 1908, the city council by appropriate resolution ordered the construction of a permanent sidewalk at grade on the east side of lot 1, specifying the kind, and that the cost be taxed against the abutting lot, and provided that “said owner, however, may construct ■above -sidewalk in accordance with the conditions mentioned .above, provided such work is done within forty-five days from date of the adoption of this resolution, and under the supervision and subject to the approval of the street commissioner of said city, and in accordance with the resolutions and ordinances of the city council.” A copy of the resolution was served on plaintiff June 8th, but at the commencement of this- action, September 16, 1908, the street had not been reduced to grade. The petition, alleged, however, that the city through its officers and employees expected to “begin cutting down said street, lowering of said sidewalk and the excavation of dirt -about the trees,” on the following morning, and defendants admitted that in the construction of the permanent walk it would be' necessary to excavate in some places thirty inches deep, but alleged this would be done in a prudent manner and asserted its right to remove the earth and construct the Walk as provided in the ordinance, and admitted its purpose so to do. Moreover, defendant by an affidavit filed declared that, “if this injunction and restraining order is dismissed by the court, affiant as the engineer of said city and street commissioner thereof will proceed at once -or as nearly as may be to bring said surface grade down to the established grade and construct a permanent and substantial walk as herein-before described in front of plaintiffs’ premises, providing the elements- will permit.” The answer conceded that the *748portion of the street between lot 1 and the curbing was not at grade as contemplated by section 779 of the Code. That-section in conferring power with respect to permanent sidewalks in cities provides that “they shall have power to provide for the construction, reconstruction and repair of permanent sidewalks upon any street, highway, avenue, public ground, wharf, landing or market place within thef limits of such city or town.; hut the construction of por>manent sidewalks shall not be made until the bed of the same shall have been graded so that, when completed, such, sidewalks will be at the established grade; and to assess the cost thereof on the lots or parcels of land in front of which the same shall be constructed.” This- was incorporated in one of the city ordinances so as to read: “It is. provided, however, that the construction of permanent sidewalks shall not be made until the bed of the same shall have been graded so that when completed the sidewalk shall be at' the established grade.”
i. Municipal cor-construction o£ wa]ks‘ An ordinance of the city required permanent sidewalks to be constructed at grade, and, as the street along lot 1 had not been brought to grade and the time within which plaintiff might have constructed the walk had elapsed, the proceedings of the city, if upheld, would have the effect of denying the plaintiff the opportunity of constructing the walk himself, a privilege expressly conferred on him, and by the resolution of the council, but the ordinances- of the city proceed on the theory that only upon the “failure, neglect or refusal of the owner or owners of the property fronting or abutting on said sidewalk to make said improvements within the time fixed in the resolution and notice” or “in case privilege is not extended by said resolution to the property owner to build said sidewalk the improvement shall be made by the city at the expense of the owner of the abutting property.” Whether the city might have put in the walk without allow*749ing the owner the privilege of doing so can make no difference. See Zalesky v. Cedar Rapids, 118 Iowa, 714" court="Iowa" date_filed="1902-12-17" href="https://app.midpage.ai/document/zalesky-v-city-of-cedar-rapids-7110239?utm_source=webapp" opinion_id="7110239">118 Iowa, 714. It is enough that this was accorded him under an ordinance conferring authority on the city to build at the lot owner’s cost only in event of his failure to do so within the time specified, and, inasmuch as he could not so perform owing to default of the city in not bringing the street to grade, the latter can not insist on constructing the walk.
Though the facts differ from those of Burget v. Town of Greenfield, 120 Iowa, 432" court="Iowa" date_filed="1903-05-16" href="https://app.midpage.ai/document/burget-v-incorporated-town-of-greenfield-7110462?utm_source=webapp" opinion_id="7110462">120 Iowa, 432, the principle is identical. It was there said: “A condition precedent to the construction of a permanent walk was the bringing of the bed of the. same to grade (Code, section 779), and this was to bo done by the town. The council, however, required plaintiff to construct a permanent walk without providing for bringing the bed of' the walk to grade and without doing so in fact.' Neither did the town point out the grade line. These things it was required to do, not only by inference from the statute, but by express provision of its general ordinance above referred to. Where a city has undertaken to avail itself of the provisions of the statute, and has fixed in its general ordinance the mode of procedure, it is limited to the mode prescribed in the ordinance. Zelie v. Webster City, 94 Iowa, 393" court="Iowa" date_filed="1895-04-06" href="https://app.midpage.ai/document/zelie-v-city-of-webster-city-7106744?utm_source=webapp" opinion_id="7106744">94 Iowa, 393. It was therefore impracticable for the plaintiff, 'at the time when the cement sidewalk in question was first ordered by the council, to comply with the order, and he is not in default in not having done so.” Converse v. Town of Deep River, 139 Iowa, 740; Waterbury v. Morphew, 146 Iowa, 313" court="Iowa" date_filed="1910-03-09" href="https://app.midpage.ai/document/waterbury-v-morphew-7113905?utm_source=webapp" opinion_id="7113905">146 Iowa, 313. We do not say that the bringing of the street to grade is a condition precedent to the adoption of a resolution ordering a permanent sidewalk. What we do hold, and so announced in Burget's case, is that this is a condition precedent to the construction of the walk, and, as the city failed to reduce the street to grade within the time plaintiff might have put in the walk, he was not in default in failing to *750make the improvement, this having been prevented by the omission of the city to perform a condition precedent to its construction. To reach any other conclusion would amount to lending our approval to a procedure which in effect would juggle property owners out of the valuable-privilege of constructing the sidewalk along their property which they are bound to keep in repair.
dissolution:' ‘ modification. Something has been said of a resolution adopted September 1, 1908, which after reciting the intention of the city council to put the street to grade and the omission. of a formal order to that effect directed the entire street to be brought to grade and . , _ the street commissioner to complete said work and carry out the order,” but the motion to dissolve was submitted on the theory that the city proposed to excavate and bring the street to grade only in connection with and as essential to the proper construction of the sidewalk. Moreover, a modification of the injunction was-not sought in the motion to dissolve; and, as the defendants, were rightfully -enjoined from proceeding, with the construction of the sidewalk, there was error in sustaining the motion to dissolve. Hughes v. Eckerson, 55 Iowa, 641.
3‘ AME‘ The temporary writ of injunction was issued without-notice to the city, -and it is contended that this- was in violation -of section 4359 of the Code, providing that “an-injunction to stop the general and ordinary business, ... of a municipal corporation . . . can only be granted upon reasonable notice of the time -and place of the application to the party to be enjoined.” The manifest design of this -statute is- that-such business of a municipality shall not be interrupted without the opportunity of being heard. Should a wrif of injunction, owing to oversight or through inadvertence,, be issued in violation of this statute, the court on 'application will set aside the order therefor 'and exact the giving of notice as required as a condition, precedent to its sub*751sequent issuance. The better practice is to move that the order be set aside, rather than that the writ be dissolved. High on Injunction, section 1615. But, if the motion to dissolve is on this ground and presented' promptly, the writ will be dissolved. Hughes v. Eckerson, 55 Iowa, 641" court="Iowa" date_filed="1881-04-07" href="https://app.midpage.ai/document/hughes-v-eckerson-7099387?utm_source=webapp" opinion_id="7099387">55 Iowa, 641.
4. Same. However, the issuance of an injunction without notice may, like other irregularities, be waived. See Williams v. Chicago Exhibition Co., 188 Ill. 19" court="Ill." date_filed="1900-10-19" href="https://app.midpage.ai/document/williams-v-chicago-exhibition-co-6969430?utm_source=webapp" opinion_id="6969430">188 Ill. 19 (58 N. E. 611); 2 High on Injunctions, sections 1580, 1615. This is done by putting in issue the allegations of the petition and submitting the cause on -the merits with or without a motion to dissolve. State v. Douglass, 75 Iowa, 432" court="Iowa" date_filed="1888-10-09" href="https://app.midpage.ai/document/state-v-douglass-7103575?utm_source=webapp" opinion_id="7103575">75 Iowa, 432; Brown v.

5. Same: But final decree might not have been entered in this case. Hpon dissolution of a temporary writ of injunction, the dismissal of the action is sometimes permissible, but it does not follow that decree of permanent injunction may ever be entered upon the overruling of a motion to dissolve. See Fadely v. Tomlinson, 41 W. Va. 606" court="W. Va." date_filed="1896-03-18" href="https://app.midpage.ai/document/fadely-v-tomlinson-6595327?utm_source=webapp" opinion_id="6595327">41 W. Va. 606 (24 S. E. 645).
corporations: injunction: notice: estoppel. • Even though such final decree may not he entered, the showing may be such as to leave no doubt as to the propriety of the writ having issued and such was the showing in the case at bar. The petition was filed September 16, 1908, and the writ of injunc- . # tion issued without notice the same day. No ... ° objection was interposed until October 17th following, when defendant filed an answer. Two days later defendants moved that the injunction be dissolved on the grounds (1) that the answer denied without evasion all the substantial facts of the petition; (2) that the injunction interrupted the excavation of the street and 'construction of the sidewalk without notice; (3) that, on the face of the petition, the injunction ought not to have been granted. This motion was supported by three affidavits and *752hearing thereon, was set for October 23d, but postponed until October 27th, whan plaintiff filed an amendment to the petition in 27 paragraphs and defendant an amendment to the answer in 9 paragraphs. Plaintiff ialso filed five affidavits in resistance of the motion and defendants two affidavits in rebuttal. Under the pleadings and affidavits, there was no dispute concerning .the material facts. The defendants ‘admitted that they were about to commit acts which were conclusively shown by them in the affidavits filed would be unlawful. Having demonstrated by affidavits in support of the motion to dissolve that the temporary writ restrained them from doing unlawful 'acts, the defendants were not in a situation to claim that these could have been any part of the general and ordinary business of the city. Hobbs v. Amader & Sacramento Canal Co., 66 Cal. 161 (4 Pac. 1147). It is no part of the business of a city to perpetrate an unlawful act, and, though under different circumstances it might be lawful, the moment its character is put beyond the pale of controversy and conceded to be unlawful .it ceases to be within the legitimate domain of municipal 'exertion. The showing demonstrated that notice was not necessary, and the motion to dissolve should have been overruled. — Reversed.
