delivered the opinion of the court:
This appeal, prosecuted by the city of Chicago and duly certified to this court by the trial judge, is from a judgment of the circuit court of Cook County which declared unconstitutional and void sections 79 — 1.4 and 79 — 106 of the Municipal Code of Chicago, insofar as they require the installation of certain safety devices on elevators owned or operated by appellees.
The record reveals that the m appellees own 141 separate units, out of a total of 166 units, housed in six buildings comprising the South Water Produce Market District, a distribution center for fruits, vegetables and produce. Each building is three stories high and has a common roof and basement; the units within the buildings are separated by common walls, are 80 feet deep, and having loading platforms at front and rear on the first floor level. Each unit is separately owned under a co-operative plan and appellees, or their tenants, conduct their businesses from one or more units. Merchandise they buy and sell is stored in the buildings and is distributed to the different levels by means of freight elevators.
Each of the units here involved is improved with an elevator of the same type, viz., an electric traction power freight elevator with hand cable control and electric magnet brake, which travels upwards and downwards in a shaft or hoistway a maximum distance of 33 feet 5 yí inches, (from basement to third floor,) at an approximate speed of 50 feet per minute. These are electric worm gear elevators and all were installed when the buildings were erected some 30 years ago. The electric motor for each elevator is set in a housing located at the top of the shaft; the elevator car is suspended on cables. Power is actuated by a continuous cable which runs in two lines along the side of the shaft from its top to its bottom, a hand pull on either of these lines being sufficient to engage the power and to cause movement in the direction desired. Between the two control lines there is suspended a center line rope which brakes the elevator when pulled downward and it appears that all three of the said lines, or ropes, hang about three feet from the front of the shaft.
There is an opening into the shaft at each level of the building. Those at the first, second and third floor levels have gates which are horizontal sliding panels, center bi-parting, the halves sliding away from one another in a vertical plane. Such gates, or doors, are either wire mesh or solid metal, the latter type having a glass panel in the upper half which permits vision into the shaft. When operated normally the gates close automatically as the car moves away from the floor, but they can be opened manually at any floor even though the car is not at that floor. Because of this feature of the doors and the proximity of the control cables to the front of the shaft, it is possible to reach into' the shaft and control the operation of the elevator from any level regardless of the location of the elevator. This cannot be done if the brake is set on the elevator but the practice of appellees’ employees is to leave the brake unlocked, thus permitting exterior operation from any level. As a result the car may be removed from a level without the knowledge of the employee who took it there, the open doors leave the shaft unguarded, and employees leaning in to reach the controls must maneuver in time to avoid the moving car. At the basement level the shaft doors are of solid steel, hinged on the side and center bi-parting, and also serve as fire doors.
Appellees’ elevators were periodically inspected by the city and were found to comply with existing ordinances up to July 1, 1954. After that date approval was refused and appellees were served with notice to make changes, alterations and repairs necessary for compliance with section 79 — 1.4 of the Municipal Code. This section was first enacted July 16, 1952, and provided as follows: “On or before July 1, 1953, every existing power elevator shall be equipped (or such equipment shall have been contracted for) with hatchway door interlocks of the hoistway unit system type which shall comply with all provisions of this chapter.” Other provisions of the chapter defined a hatchway door interlock as a device “to prevent the operation of the machine to move the car away from a landing unless the hatchway door at the landing is in a closed and locked position; and to prevent the opening of the hatchway door from the landing side except by special key, unless the car is at rest within the landing zone, or is coasting through the landing zone, with its operating device in a stop position.” A hoistway unit interlock system is defined as: “An interlock system which will prevent the operation of the car unless all hatchway doors are locked in a closed position.” Such devices would not permit the method of operation practiced by appellees and their employees.
On July 28, 1954, section 79 — 1.4 was amended to provide that: “On on before July 1, 1954, every existing power elevator, except rope-geared hydraulic elevators, steam elevators and gravity elevators (friction) shall be equipped with hatchway door interlocks of the hoistway unit system type which shall comply with all the provisions of the chapter.” Shortly after the latter enactment, appellees, who had not complied with the original ordinance, commenced this proceeding for a declaratory judgment that the amended ordinance is an improper exercise of the police power which deprives them of their property without due process of law, that the classification which serves to except certain types of elevators is discriminatory and unconstitutional, and that the ordinance is unreasonable and void insofar as it applies to their elevators.
The master, who heard the evidence in the cause, concluded from principles established by the decisions of this court that the city had the power both to pass the ordinance and to give it retroactive effect, and that it was a reasonable and proper exercise of the police power. However, because he could see no reasonable basis for excluding the excepted types from its operation, he concluded section 79 — 1.4 created an arbitrary and discriminatory classification which rendered it void. The trial court, by a judgment entered July 19, 1956, concurred with the latter conclusion of the master, but held in addition that the retrospective application of the ordinance was an improper exercise of the police power, that it was confiscatory and void as applied to appellees’ elevators, and that the resulting public benefits did not justify the damage and burden to appellees. The court refused to' consider a supplemental pleading filed July 13, 1956, which set forth that a further amendment to section 79 — 1.4 had been introduced before the city council, and which prayed that the cause be continued for a reasonable time pending the disposition of the proposed amendment.
The parties agree in the briefs filed in this court that, two months after the entry of the judgment, the city council adopted the proposal referred to and amended section 79 — x-4 by the addition of the following paragraph: “On or before July 1, 1958, every existing rope-geared hydraulic elevator, steam elevator and gravity elevator (friction) shall be equipped with hatchway door interlocks of the hoistway unit system type which shall comply with the provisions of this chapter.” This amendment thus removed the arbitrary classification found to exist when this proceeding was decided. Citing People ex rel. Toman v. Mercil & Sons Plating Co.
Little merit can attach to the present contention of appellees. Nothing in the record supports the charge that the amendatory paragraph added in 1956 was for any purpose other than a legitimate exercise of the police power directed at protecting human life. On the other hand it is shown that hydraulic, steam and gravity elevators, not being powered by electricity, require more extensive conversion to permit compliance with the ordinance, thus causing need for a greater period of time in which to comply. Under the latter circumstance it must be said there existed a reasonable basis for the legislative distinction complained about. We conclude that the issue of an arbitrary classification between elevators became moot with the amendment of 1956, and that the distinction made in such amendment has a reasonable basis.
Appellees concede the regulation of elevators is a field in which the city has been granted authority to exercise its police power, (See: Marcovitz v. Hergenrether,
The power of a governmental body to require changes in existing structures for the protection of health and safety is the subject of an annotation found in
The application of the foregoing principles has produced varied but consistent results within our own jurisdiction. In Masonic Fraternity Temple Assn. v. City of Chicago,
Looking to other jurisdictions we find it was held not unreasonable in Adamec v. Post,
Although appellees have alleged their elevators are “consistent with the highest standards of health and safety,” and have proved compliance with past ordinances, as well as a comparatively low death and accident rate, such factors are no bar to the exercise of the police power granted to the city, nor do they render a requirement for new safety devices oppressive and unreasonable. Based upon advances in engineering, and no doubt upon experience gained during the thirty years appellees’ elevators have been in operation, the city has determined that the greatest protection to human life is to be realized by door interlocks which will prevent the operation of elevators unless hatchway gates are closed, and permit the gates to open only when the elevator car is at the gate level. In requiring all power elevators to be so equipped the city has done no more than to exercise its continuing power to make regulations needful to the common good and general welfare, subject to which all property is held. As pointed out in Clarke v. City of Chicago,
For its concluding point the city argues, and we find correctly so, that the trial court erred when it held section 79 — 106 of the Municipal Code to be void and unenforceable against appellees. It is fundamental that a judgment order must be supported by allegations in the complaint as well as by the evidence. (Stowell v. Satorius,
