Opinion by
Beaver, J.,The affidavit of defense in this case, held by the court below to be sufficient to prevent judgment, was filed in a suit brought for the recovery of license fees imposed by the plaintiff against the defendant for the maintenance of telephone and telegraph poles and wires upon the streets and highways of the plaintiff borough.
The affidavit sets forth: “ That the said plaintiff is not, and was not during said period mentioned in the statement of claim filed in this case (the period for which license fees were charged), under any additional or incidental liability, of any kind or nature whatsoever, in looking after the safety of said poles and wires and the maintenance thereof; and is not, or was not, under any additional or incidental liability for any injuries to persons or property which might have arisen, or did arise, during said period, or could possibly arise, by reason of the erection of the said poles and wires within the limits of the said borough. That the said charges were made without any kind *353or character of expense or liability having been incurred by the said borough of Collingdale. That the said license charge imposed by the said ordinance is not based upon the cost and expense to said borough for inspection, regulation and supervision of the defendant’s lines and business; and the said charge is more than twenty times the amount that might have been, or could possibly be, incident to such inspection, supervision and regulation, together with all reasonable measures and precautions that might have been, or possibly could be, required to be taken by the said borough for the safety of its citizens and the public, or which might have been, or possibly could be, incurred as expenses for the most careful, thorough and efficient inspection and supervision that might have been made to the said poles and wires and the issuing of said license, and notwithstanding, as above set forth, the fact that the said plaintiff has not and does not maintain any inspection, supervision, or care whatsoever over said poles and wires of the said defendant company, and has not incurred any expense whatsoever on account thereof.”
The facts set forth in this paragraph of the affidavit of defense are practically identical with, if not stronger than, those set forth in the affidavit in Lower Merion Twp. v. Postal Telegraph Cable Co., 25 Pa. Superior Ct. 306, in which we held, following the case of Postal Telegraph Cable Co. v. Taylor, 192 U. S. 64, that an affidavit of defense “is sufficient to prevent judgment which avers'that the license tax was not based upon the cost for inspection by the township,-that it was more than twenty times the amount that might have been, or could possibly be, incident to such inspection,” etc. The averments in the affidavit under consideration being quite as sweeping as those contained in the affidavit in the case above referred to, and the court below having followed our ruling in that case, we are not disposed to convict it of ¿rror for having done so.
In that case, it is true, we were controlled by the decisions of the supreme court of the United States in the cases therein cited and in this case we are not. Hence, it cannot be said that the Lower Merion case rules the present. It is true, also, that there are numerous decisions of the Supreme Court of Pennsylvania and of our own court, in which recoveries under ordinances, imposing a license fee of $1.00 per pole and $2.50 *354per mile of wire, have been sustained. It is to be observed, however, that in none of these cases — excepting the Borough of Taylor case, 192 U. S. 64, which was overruled — was it alleged that the amount of the fee was so grossly disproportioned to the cost of issuing the license and of thorough and efficient police supervision, as it is alleged to be in this case. Nor do any of those cases lay down a rule which forbids inquiry into the reasonableness of the amount of the fee in an action brought therefor. As, in the nature of things, it is ordinarily impossible to determine in advance the exact cost, the municipality is at liberty to make the charge large enough to cover any reasonably anticipated expense, and payment of the fee cannot be avoided because it may appear subsequently that it was somewhat in excess of the actual expense of supervision. Presumably municipal officers will act in good faith and exercise their best judgment and have regard only to the purpose for which the fee may be exacted lawfully in fixing the amount, for that is their duty; but their power is not absolute, nor is their action irreviewable by the courts. “We are not bound to uphold an ordinance adopted ostensibly as a police measure, but used as a mere subterfuge for the purpose of raising revenue. Courts will not sustain municipalities in such abuse of their powers, if it be shown: ” Kittanning Borough v. Kittanning Consolidated Natural Gas Co., 26 Pa. Superior Ct. 355. Unless we are prepared to hold that any municipality has power to fix the amount of the fee at more than twenty times the cost that can possibly be incident to the accomplishment of every purpose for which such fee can be exacted, this appeal should be dismissed and the defendant permitted, if it can, to prove the facts. If the allegation as to the gross disproportion between the fee and the amount of any expense that might have been reasonably and fairly incurred, for the most careful, thorough and efficient inspection and supervision possible and for all measures and precautions that could be required to be taken by the municipality for the safety of its citizens and the public, be proved, there can be but one inference and that is that the ordinance was not adopted as a police measure, but was really intended for revenue purposes, and, therefore, the court ought to declare it unreasonable and void. We apprehend that the defendant may *355find it difficult to 'establish this sweeping allegation, but all that we decide at present is that it should be given the opportunity to do so, if it can.
The order of the court below, discharging the rule for judgment for want of a sufficient affidavit of defense, is, therefore, affirmed and the appeal dismissed without prejudice at the cost of the appellant.
