delivered the opinion of the court:
Gustаve E. Koy filed a bill in the circuit court of Cook county on November 28, 1913, in behalf of himself and of all other persons similarly situated, to restrain the city of Chicago and its officers from revoking licenses issued to him as a milk dealer and from interfering with the distribution of milk products by him and by others similarly situated, for failure to comply with certain provisions of sections 1273 and 1274 of the Chicago code of 1911, as they were amended by аn ordinance of August 14, 1912.. A preliminary injunction was ordered, but on motion of the' defendants it was dissolved and a demurrer was sustained to the bill, which was dismissed for want of equity. The complainant has appealed to this court, the validity of an ordinance being involved and the court having certified that the public interest required that the appeal be brought to the Supreme Court.
The. bill alleges that the complainant for ten years has conducted a milk business in the city of Chicago, and has furnished to a large number of citizens, and is now delivering, clean, pure, pasteurized milk, and has complied with all ordinances of the city of Chicago relative to purity and cleanliness; that on January 7, 1913, he obtained licenses to conduct his business and run six wagons; that the product handled by him is perishable, and the ordinance requires him to mark his product on the cap on the day on which the milk was pasteurized and dispose of the milk on the day following; that he complies with this requirement, and if he is prevented from disposing of his milk on the day following, as marked on the cap, he loses the entire product not sold, as the ordinance prohibits him from re-pasteurizing and re-capping, and that his daily loss would amount to $168; that it is necessary for him to deliver the milk product at an early hour each day; that there are other persons similarly situated in the business and they handle 135,000 gallons of milk each day, and if they are prevented from selling and delivering the same on the day following the pasteurization the product will become a total loss, amounting to $35,000 a day; that the total value of their business in the city is worth $500,000, and that there are more than twelve hundred persons engaged in the business, scattered over a territory of 191 square miles.
It is further alleged that on August 14, 1912, the city council of the city of Chicago passed an ordinance regulating the producing, handling and sale of pasteurized milk, which amended sections 1273 and 1274 of the Chicago code of 1911. In accordance with paragraph (Ji) of article “B” of section 1273 the complainant installed and is operating a pаsteurizer, and he has complied with the ordinance in regard to notifying the commissioner of health of such pasteurizer and has obtained a permit to operate the same. The milk used by him is obtained from farms which have been inspected by the commissioner of health, and it is such that ninety-nine per cent of the bacteria and all pathogenic bacteria are killed and the milk treated at the tеmperature required .in paragraphs (/) and (i) of article “B” of the ordinance. In all pasteurization the product is heated to the temperature required by the ordinance and fixed by the commissioner of health, and in accordance with paragraph (k) of article “B” of the ordinance all milk is properly labeled on the cap of every package and on tags attached thereto and the day of the pasteurization is plainly marked thereon. In accordance with paragraph (m) the product is cooled at a temperature of forty-five degrees without being exposed to contamination. The apparatus used can be readily cleaned and sterilized, as required by the ordinance. The pasteurized product complies with the provisions of the ordinance and does not contain more bacteria per cubic centimeter than is within such provisions. The department of health has notified the complainant that it is going to enforce paragraph (i) of article “B” of the ordinance, which refers to pasteurization, and is as follows:
“All continuous pasteurizers shall be equipped with feeding pipe which is SO' constructed that the pasteurizer can not be fed in excess of its normal working capacity,—that is, in excess of the working capacity of the machine at which ninety-nine per cent of the bacteria are killed when the required amount of heat is applied. A recording apparatus shall be installed upon all pasteurizers, to record, during operation, the temperature of the pasteurized product as it flоws from the heater. The thermometer of this recording apparatus must be accurate and kept submerged . in the milk in such a way that it is not exposed to escaping steam or other heat except the heated- milk: Provided, that if the pasteurizing is done in bottles or in other final containers, the temperature recording apparatus must be attached and adjusted in a manner so as to accurately record the temperature to which the milk, cream, skim milk or buttermilk is- raised and the duration of time for which said temperature is maintained. The records made by this recording thermometer must be accurate and made in a chamber which is kept under lock and key in the control of the commissioner of health'. The mechanism of the pasteurizer or pasteurizing system shall be such that the three important elements, namely, the temperature, time of exposure and the quantity of milk exposed at one time, can be readily kept under control and observation by the commissioner of health.”
It is further alleged that the recording apparatus required is of no benefit to the appellant, for the reason that he now has and uses thermometers and apparatus by which he can determine at whаt temperature his product is pasteurized and for what length of time the product so' pasteurized'is kept at that temperature and can comply-with the requirements of the ordinance in regard to- properly pasteurizing milk without the recording apparatus mentioned in the ordinance, and that the requirement of the ordinance in this respect is unreasonable and. -unjust and would require the expenditure of between $45 and $220 for useless apparatus which would not benefit the city or the health department in enforcing compliance with the ordinance. The bill further alleged that the ordinance is ambiguous and uncertain; that there is no device which will comply with the requirements of the ordinance; that the only devices on the market to meet the requirements are complicated and expеnsive and cost in the neighborhood of $65, the cheapest costing from $45 up; that on all flash pasteurizers an additional requirement of a controller would be necessary, costing $185 for the cheapest, and that such devices have never been proved to be correct but have been proved to be incorrect. It is further alleged that all the devices offered for sale to meet thе requirements of the ordinance are worthless and do not guarantee compliance with the ordinance because of defects in their construction or operation, which are described, and because of the ease with which they can be manipulated so as to show incorrect results ; that none of these recording devices furnish reliable information as to compliancе with the ordinance unless kept under lock and key, and that it would be impossible for the officers of the health department to- visit the various places throughout the area of the city of Chicago where milk is pasteurized, between the- time of one pasteurization and the next, and the ordinance could not be enforced without stationing an inspector in each place during the entire oрeration of pasteurization, and in such case there would be no necessity of having the recording devices.
. Various technical objections to the bill of complaint as a pleading have been urged by the appellees in their brief which seem to be of considerable force, but since we have arrived at the conclusion that the decree is right upon the merits they will not be further mentiоned. The bill is founded upon the proposition that the ordinance is unreasonable, unjust and oppressive and should therefore be held void. When the legislature has authorized a city council to pass ordinances upon any subject, the power thus conferred must be reasonably exercised. Whether its exercise in a particular case is reasonable is a judicial question, and an unreasonable ordinance will be held void by the courts. The regulation of the sale of milk and its products is essential to the preservation of the public health, and authority for its regulation is clearly given to the city council by paragraphs 50, 53, 66 and 78 of section 1 of article 5 of the Cities and Villages act. (City of Chicago v. Bowman Dairy Co.
It is argued that the apparatus is of no benefit to the appellant because he has, and is using, thermometers and apparatus by which he can comply with the requirements of the ordinance in regard to properly pasteurizing milk at the temperature and for the length of time required in the ordinance without the use of the recording apparatus, and that such apparatus has no effect upon the food product itself. The object of the ordinance is not to benefit persons engaged in the milk business or to enable them to comply with the ordinance in regard to pasteurizing njilk, but is to make sure that the milk offered for sale within the city shall be of a quality which will not be detrimental to the public health. The city having power to require milk to be pasteurized is not limited to the imposition of a penalty for a violation of this requirement, but may prescribe the conditions under which the pasteurization shall be done in order to prevent an evasion of the ordinance and insure that the product shall be such as the ordinance requires. In City of Chicago v. Bowmаn Dairy Co. supra, an ordinance was held to be a valid exercise of the police power which required every glass bottle or jar in which milk or cream was sold or offered for sale to have its capacity blown into it or otherwise permanently and indelibly indicated on it, and the fact that the effect of the ordinance was to' deprive persons of the use of their bottles on hand at thе time the ordinance was adopted did not render it invalid. In City of Chicago v. Schmidinger,
It is contended .on behalf of the aрpellant that the ordinance is, in effect, the same as a requirement that the appellant and other milk dealers shall pay for deputy health inspectors of the city for the purpose of detecting violations of the ordinance, and that this police duty is a purely public burden, which cannot -be cast upon the individuals who happen to be engaged in the business concerned. The cаse of City of Chicago v. Weber,
The appellant insists that the recording device is impracticable ; that the record can be made by using water and heating it, without any milk; that the pointer can be manipulated to show a temperature different from the actual temperature; that the dial can be tаken out and marked by hand, and that the number of dealers and extent of territory covered by them is so great that it would be physically impossible for the officers of the department of health to visit the places where milk is pasteurized and change the dials between the time of each pasteurization and the next. These are questions of judgment and discretion, the determination of which must be left to the legislative department. If the apparatus should not record the temperature accurately at all times or should not indicate the length of time the temperature was maintained, or if it can be manipulated so as not to show an accurate record, these are matters for the city council to consider. Courts cannot overrule the determination by the city council that a particular method of protecting the public health should be adopted unless it is so clearly and manifestly wrong that there can be no doubt about it. A personal inspection of all milk sold in the city would be manifestly a requirement difficult, if not impossible, to carry out. Even though the recording apparatus may be manipulated by a dishonest dealer so as to show an untrue record, the city council may have thought its use better for the protection of the public than a system by which no record was preserved but the health officers were compelled to rely wholly upon the dealer, and we cannot say that they were clearly and unmistakably wrong. Whether officers of the health department shall be provided in sufficient number to visit the places where pasteurization talces place between each pasteurization and the next is also a question for the council.
The decree is affirmed.
iw* affirmed.
