* Motion for rehearing denied, without costs, on January 18, 1944. Action was commenced July 28, 1938, by the city of Milwaukee, plaintiff, against the Public Service Commission of Wisconsin, the town of Greenfield, and the city of West Allis, defendants, to set aside an order of the Public Service Commission establishing rates and rules for extension of water service by the city of West Allis to Lapham-Orchard Sanitary District in the town of Greenfield, Milwaukee county, Wisconsin. The trial court ordered judgment dismissing plaintiffs complaint, and plaintiff appeals.
On the 18th of February, 1938, the city of West Allis made application to the Public Service Commission for the prescription of rates and rules for extension of water service to the Lapham-Orchard Sanitary District in the town of Greenfield, Milwaukee county, Wisconsin. At the hearing the city of *Page 74 Milwaukee appeared in opposition to the application, objecting to the jurisdiction and authority of the commission to hear the application. On the 27th day of May, 1938, the commission entered an order establishing rates for the proposed service. On June 8, 1938, the city of Milwaukee applied to the commission for a rehearing on said order, which application was denied on the 24th day of June, 1938. Thereafter the city of Milwaukee instituted this action.
It is undisputed that the city of West Allis, a municipal water utility, purchases its water from the city of Milwaukee, a municipal water utility, and that the Lapham-Orchard Sanitary District in the town of Greenfield is contiguous to the city of West Allis but does not adjoin the city of Milwaukee. At the trial plaintiff offered testimony to show the additional cost to the city of Milwaukee by reason of the city of West Allis supplying water to the town of Greenfield, and the effect the extension of this service would have upon the Milwaukee utility. The court refused to receive this evidence. No other evidence being offered, the court granted the motion to dismiss plaintiff's complaint and ordered judgment accordingly. The right of the city of West Allis to extend water service to the Lapham-Orchard Sanitary District was granted on a previous application to the Public Service Commission of Wisconsin, and was before this court in Milwaukeev. Public Service Comm. (1939) 232 Wis. 397, *Page 75 287 N.W. 682. The only question before the court at this time is the reasonableness of the rules and rates for this service. This affects the city of West Allis and the patrons in the district to be served. None of them has appealed. The fact that the city of Milwaukee may be selling water to the city of West Allis does not make it a party in interest which entitles it to maintain an action to set aside an order of the Public Service Commission fixing the rates to be charged by the city of West Allis. The court properly rejected the evidence offered by the plaintiff. This case is ruled by Milwaukee v. Public ServiceComm. supra.
Appellant contends that it has a right to have determined in this action the authority of the city of West Allis to extend its water service to the town of Greenfield, which may place additional burdens on Milwaukee's water utility, under its contract, express or implied, to furnish water to the city of West Allis, and that, if the subject matter is not properly before the commission and the court in the proceeding to establish rates for the service rendered to the town of Greenfield, it is properly before the court under the rule that two causes of action can be joined in one complaint, even though there be different forms of relief as against different defendants and different forms of relief in one action, citing Statev. P. Lorillard Co. 181 Wis. 347, 193 N.W. 613.
The position of the appellant cannot be sustained. This is a proceeding before the Public Service Commission to establish rates for service to be rendered by the city of West Allis. Nothing more was before the commission. The commission properly refused to permit appellant to try issues existing between it and the city of West Allis at the hearing. It is proper for a party in interest to bring an action in circuit court to review the reasonableness of the order. It is held in this case that the city of Milwaukee is not affected by the order and so has no interest which entitles it to maintain an action to set the order aside. To hold that the appellant has a right to *Page 76 bring this action and maintain it under the rule of law claimed would be to say that a stranger to a proceeding could come into court at any time and bring an action to review an order of the commission to enable him to try out a difference existing between the third party and some party to the hearing before the commission. The appellant does not come within the rule of law it is attempting to invoke. If a difference exists between the city of Milwaukee and the city of West Allis it must proceed before the Public Service Commission or the courts, as the facts and the law in the case require.
By the Court. — Judgment affirmed.
