delivered the opinion of the court:
Two defenses are relied upon by the city. The first is, that there is a variance between the allegations of the declaration and the proof, in that the declaration alleges, that the plaintiff stumbled and fell into a catch-basin, and the proof offered shows, that the plaintiff was injured by stepping into a sewer inlet situated several feet from the catch-basin. The second defense is, that the sewer inlet in question was constructed in accordance with a general plan devised through no error in-judgment under the direction of the municipal authorities.
First—As to the variance. It is true, that the second count of the dеclaration charges that the defendant permitted a certain catch-basin below the intersection of said streets to remain open and uncovered, and that it did not place guards or barriers around the same, nor lights so as to give warning and protect passers-by, and that plaintiff fell into said catch-basin. But the first count alleges, that the defendant permitted “a deep and dangerous hole over and into a certain catch-basin below said streets to remain open and uncovered.” Proof, that the defendant fell into a hole, is not at variance with the allegation that he fell into a “hole over and into a certain catch-basin;” the hole was really a sewer inlet, designed to carry the water off into the catch-basin.
But if there was a variance in the respect thus indicated between the declaration and the proof, the question of such variance is not properly raised and preserved in the record. At the conclusion of the plaintiff’s evidence, counsel for defendant moved to strike out the plaintiff’s testimony on the ground of variance between the declaration and the proof, but the motion did not point out what the variance was, or in what it consisted. Where the defendant moves to strike out plaintiff’s evidence on the ground of variance, it is incumbent on him to point out in what the variance consists, so as to enable the court to pass upon the question intelligently, and also to enable the plaintiff to amend his declaration, so as to make it conform to the proof, and to avoid defeat upon a point not involving the merits of the claim. (Libby, McNeill & Libby v. Scherman,
Second—As to the construction of the sewer inlet in accordance with the general plan. The question, sought to be raised upon this branch of the case, arises out of the refusal of the court to give the refused instructions of the defendant, which are set out in the statement preceding this opinion. It is well settled, that municipal corporations have certain powers which are discretionary or judicial in chаracter, and certain powers which are ministerial. The powers of such corporations have also been divided into those which embrace governmental duties, such as are delegated to the municipality by the legislature, and in the exercise of which the municipality is an agent of the State; аnd those powers which embrace quasi private or corporate duties, exercised for the advantage of the municipal locality and its inhabitants. Municipal corporations will not be held liable in damages for the manner in which they exercise, in good faith, their discretionary powers of a рublic, or legislative, or quasi judicial character. But they are liable to actions for damages when their duties cease to be judicial in their nature, and become ministerial. (2 Dillon on Mun. Corp. secs. 949, 832; Tiedeman on Mun. Corp. sec. 324). Official action is judicial where it is the result of judgment or discretion. Official duty is ministerial, whеn it is absolute, certain and imperative, involving merely the execution of a set task, and when the law which imposes it, prescribes and defines the time, mode and occasion of its performance with such certainty, that nothing remains for judgment or discretion. (People v. Bartels,
It has been said, that the work of constructing gutters, drains and sewers is ministerial, and that the corporation is responsible in civil actiоns for damages caused by the careless or unskillful manner of performing the work. (2 Dillon on Mun. Corp. sec. 1049). It is the duty of a municipal corporation, which exercises its power of building sewers, to keep such sewers in good repair, and such duty is not discretionary but purely ministerial. (1 Shearman & Redfield on Negligence, sec. 287; 2 Dillon on Mun. Corp. sec. 1049). The adoption of a general plan of sewerage involves the performance of a duty of a quasi judicial character, but the construction and regulation of sewers and the keeping of them in repair, after the adoption of such general plan, are ministerial duties, and the municipality, which constructs and owns such sewers, is liable for the negligent performance of such duties. (1 Beach on Public Corp. sec. 766; Johnston v. District of Columbia,
By the terms of the City and Village act, which has been adopted by the city of Chicago, the city council in cities has power to lay out, to establish, open, alter, widen, extend, grade, pave or otherwise improve streets, alleys, avenues, sidewalks, wharves, parks and public grounds, and vacate the same; to regulate the openings therein for the laying of gas or water mains and pipes, and the building and repairing of sewers, tunnels and drains, and erecting gaslights; to construct and keep in repair culverts, drains, sewers, and cesspools, and to regulate the use thereof. (Rev. Stat. 1874, chap. 24, art. 5, sec. 63.) The city, being thus required by law not only to construct but to keep in repair its culverts, drains, sewers and cesspools, is liable in damages for a neglect tо perform said duties. It has always been the doctrine of this court, that, while the legal obligation of the city to construct gutters and grade and pave streets is one voluntarily assumed, yet that, when the city- constructs these improvements for the benefit of the public, it then becomes the duty of the city to see that they are kept in repair. (City of Alton v. Hope,
Counsel for the appellant invoke the doctrine, which seems to prevail in the State of Michigan, that, while complаint is made that the original plan of a city improvement is so devised as to render the work dangerous when completed, the fault found is with legislative action, and that a suit grounded upon it is grounded upon a wrong attributable to the legislative body itself; that the wisdom and propriety of local legislative action can not be made a judicial question; that it is and must be a political question, and can arise only between the legislator and his local constituency. The Michigan doctrine is announced in the two cases of City of Detroit v. Beckman,
The rule of exemption, growing out of the discretionary powers with which cities are invested in the matter of arranging plans for the prosecution of public improvements, and where they act under the advice of skilled and experienced persons, is carried too far in the Michigan cases referred to; the rule should not be construed, so as to relieve “the city from liability when the plan devised, if put in operation, leaves the city’s streets in a dangerous condition for public use.” (Tiedeman on Mun. Corp. sec. 350.) Legislative authority only relieves municipal corporations, which make public improvements, frоm responsibility for the necessary and usu,al results of a proper exercise of the powers conferred upon them. (15 Am. & Eng. Ency. of Law, 1154.) But the necessary and usual results of the proper exercise of such powers do not include such negligent and unskillful performance of the work as exposes travelers upon the public streets to unusual dangers. (City of North Vernon v. Vogler,
We do not think, that there was any error in the admission of the evidence of the expert witness who was examined by the plaintiff. His testimony was directed to the point that, if the opening or sewer inlet to a catch-basin is more than one foot wide, it is practicable to put an iron grating over it. It appeared that the witness had been a sewer-builder for the city for eighteen years, and was familiar with the construction of catch-basins, inlets and openings of sewers.
The judgments of the Appellate Court and of the Superior Court of Cook county are affirmed.
Judgment affirmed.
