Dodge, J".

The question here needing to be decided is a very narrow one. Counsel on both sides are agreed, as are the authorities in this state, that relator, being a telephone company, has by grant of the legislature a franchise to lay or erect its wires in the streets of the city of Milwaukee, but that such city has the power of reasonable police control and regulation over exercise of such franchise. The limits of this power have been suggested in several cases, notably in Marshfield v. Wis. Tel. Co. 102 Wis. 604, 78 N. W. 735; State ex rel. Wis. Tel. Co. v. Sheboygan, 111 Wis. 23, 86 N. W. 657; S. C. 114 Wis. 505, 509, 90 N. W. 441; Wis. Tel. Co. v. Milwaukee, 126 Wis. 1, 104 N. W. 1009. This power of regulation includes the prescribing of those streets upon which it is deemed consistent with the public good that the wires may be placed and those from which they should be excluded (Marshfield v. Wis. Tel. Co., supra); also method of construction so far as public welfare is legitimately concerned (State ex rel. Wis. Tel. Co. v. Sheboygan, supra). The company having this franchise, subject only to such police regulation, has a right to have prescribed, and the municipality owes a duty, upon proper application, to *618prescribe, such restrictions and regulations as it deems necessary. In prescribing the same of course there is a broad field of legislative discretion which may be exercised, but the discretion is limited to that which is reasonably necessary and is consistent with the purpose of the general law giving to the company its right and franchise to conduct its business in and over the highways of the city. The city may not, under the guise of regulation, practically exclude such company. State ex rel. Wis. Tel. Co. v. Sheboygan, supra; Le Feber v. West Allis, 119 Wis. 608, 97 N. W. 203. Of course no duty rests on the city to approve a plan of streets or to prescribe regulations for such corporation until due application therefor is made, for otherwise the city is not informed that any such corporation is in existence or is desirous of using any of the streets.

This duty of the city above outlined is legislative. In Milwaukee, as in most other cities, it is primarily vested in the common council. Hence the specific duty of exercising this legislative discretion, to the end of promulgating reasonable provisions and regulations, rests upon that branch of the city government, and no provision of law or charter has been called to our attention giving to any other officer, board, or commission of the city any power or authority until after the coxuicil acts. As said in the first Sheboygan Case (111 Wis. 23, 41, 86 N. W. 657), when proper application is made it becomes the duty of the common council to act, but, since its act involves exercise of discretion, a court cannot in advance prescribe what that action shall be, but can and will in case of refusal command that some action be taken. They may be commanded to act, but not how to act. It is a principle thoroughly established, however, that courts will not exert their power, by the drastic writ of mandamus, as against public officers, to compel action in favor of an individual which has not prior thereto become definite and been clearly and unequivocally demanded of such officer. Espe*619cially is that principle applicable bere, where generally no duty to act rests either upon the city or any of its officers, until informed of the desire of a company such as the relator for action.

O'Donnell v. Benzenberg, 108 Wis. 435, 84 N. W. 858; State ex rel. Board of Ed. v. Hunter, 111 Wis. 582, 588, 87 N. W. 485.

As we have already said, the common council is the only-branch of the city government which is vested with authority to first promulgate the plan and regulations under which, the relator is to operate, and therefore the only body upon which any legal duty rests. The mayor and the board of’ public works, therefore, are not shown at the present time to-be charged with any legal duty, and, had they separated in their attack upon the proceedings, might well have been dismissed from consideration. But when we turn to the situation presented by the proceedings taken by the relator we-find them barren of any request or demand upon the common council to take any step which the law imposes upon that body. The sole request of' the petition presented to it was-that -it refer the plan accompanying that petition to the board of public works. There is nothing pointed out in statute or charter imposing any such duty on the council. Its-duty was to exercise its legislative discretion and take action to prescribe a plan and regulations under which the relator-might act. But that action has not been requested. Hence,. *620under tbe familiar rule above stated, it is not for tbe court to command wbat tbe relator has not seen fit to give tbe council an opportunity to do before suing out tbis writ.

Tbis objection to tbe proceedings is fundamental, -and may well relieve us from tbe discussion of tbe many objections in detail to tbe pleadings and proceedings witbin tbis action. Of itself it is sufficient to require tbat tbe writ be quashed.

By the 'Court. — Order appealed from is reversed, and cause remanded with directions to tbe circuit court to quash tbe- alternative writ.
