It is very vigorously claimed by both of the appellants that the single finding of fact made by the court to the effect that the order of August 23, 1912, “is unreasonable” is not a- response to sec. 2863, Stats., which requires that upon trial of an issue of fact by the court, the judge shall state in his decision “the facts found by him.” It is argued that the court should under this provision make findings of the fundamental facts upon which the ultimate conclusion of unreasonableness is based, such as (1) the fair value of the property used by the plaintiff in its business, (2) the reasonable rate of return thereon, and perhaps other facts, such as the amount of the original investment, the cost of reproduction, the going value, the rate of depreciation, etc.
The argument is not without considerable weight, and it is beyond question that it would simplify the question arising on the appeal and make the work of-this court easier if the fundamental facts, upon which the ultimate conclusion of unreasonableness is based, were stated. However we are unable to convince ourselves that such was the intention of the lawmaking power. This action is a purely statutory action, created by the railroad commission law for the sole purpose of providing a court review of an order of the Commission regulating railroad rates or service to determine whether the order is unlawful or unreasonable.
Sub. (e), sec. 1797 — 16, Stats., provides for the bringing of the action, and declares that “in all trials under this section” the burden of proof shall be upon the plaintiff “to show by clear and satisfactory evidence that the order of the,commission complained of is unlawful, or unreasonable, as the case may be.” The court is nowhere directed or empowered to find the lawful or reasonable rate; indeed the power to fix future rates is not a judicial power, though the power to determine whether existing rates are reasonable is judicial in its nature. Madison v. Madison G. & E. Co. 129 Wis. 249, 108 N. W. 65.
*426The court must be convinced that the rate fixed in the order is unlawful or unreasonable, but it is neither required nor expected to find what rate would be reasonable. The fact to be found is a single negative fact, not a number' of affirmative facts. We think, therefore, that the single finding of unreasonableness in the present case satisfies the calls of the statute.
The next claim made by the appellants is that the trial judge based his decision, not upon the evidence before him, but upon the supposed fact that the order in the Woehsner Case rescinded the order of August 23, 1912, ab initio, and thus deprived the last-named order of the statutory presumption of reasonableness.
That the trial judge did this very thing cannot be doubted. In a written opinion filed he said:
“The order directing the sale of thirteen tickets for fifty cents was based upon the Commission’s forecast of the future. The order in the Woehsner Case was based upon the actual results of operation under the order. The finding of the Commission that the order directing the sale of thirteen tickets for fifty cents was unreasonable and that it “would not have been made” if the Commission had understood the nature of the changes then in progress in connection with plaintiff’s businesses ‘prima facie lawful and... reasonable.’ Sec. 1797 — 15, Stats. That finding must stand until it is shown ‘by clear and satisfactory evidence’ that it is ‘unreasonable or unlawful.’ Sub. (e), sec. 1797 — 16, Stats. If upon the record the order in the Woehsner Case is such that ‘reasonable men might well differ with respect to its correctness, (it) cannot be said to be unreasonable.’ Minneapolis, St. P. & S. S. M. R. Co. v. Railroad Comm. 136 Wis. 146, 165, 116 N. W. 905.
“If the court cannot say that the order in the Woehsner Case is unreasonable, then the finding of the Commission in that case takes from the order here in question the statutory presumption of reasonableness. That presumption is based on the sanction which a finding of the Commission gives to it. When that sanction is taken away by the action of the Commission in vacating its former order and determining that such order is unreasonable, the former order is no longer *427supported by such statutory presumption. It is manifest that the court cannot sustain both orders of the Commission. If the statutory presumption in favor of the order in the Woehsner Case is not overcome by clear and satisfactory evidence, the order in the Fare Case must be held to be unreasonable, as the Commission has found it to be.”
The judge then takes up the question whether the evidence shows that the findings in the Woehsner Case are unreasonable and concludes that it does not. On this line of reasoning the conclusion necessarily followed that the order in the Woehsner Case wiped out the order of August 23, 1912 (called the order in the Fare Case), and left the court nothing to do but to declare it unreasonable and set it aside.
To our minds this is an erroneous interpretation of the statute. Both orders may be upheld and both undoubtedly have the statutory presumption of reasonableness. The scheme of the statute is that when the Commission in a proper proceeding makes an order regulating fares, that order conclusively determines the lawful and reasonable rate at the time the order is made, except that it may be reviewed by action brought within ninety days, as the present action was brought.
It is not provided or contemplated that the order may be reviewed in another and different proceeding before the Commission, that is, reviewed as to its reasonableness at the time it was made. Of course upon complaint made at any time to the Commission the subject of the present reasonableness of the rates may be examined and new rates fixed, but this does not mean that the previous order is to be declared void ab initio. Up to the time the new order is made the rates fixed (by the original order are lawful and the making of the new order simply substitutes another rate as the lawful one from that time onward. This seems to us so clear from a study of the statute (secs. 1797 — 14 to 1797 — 16, inclusive) that we shall spend no further time upon the proposition.
The provision that the Commission may “rescind” an or*428der fixing rates previously made by it is manifestly not to be construed as retroactive, that is, that the previous order is to be made void from the beginning. The word “rescind” may have such a meaning, but its more frequent meaning is, to presently nullify, repeal, or vacate. To give it the retroactive meaning contended for would mean that neither carrier nor patron would ever know whether rates were legal or not. A rate supposed by both parties to be legal one year might be discovered to be illegal the next year, with the resulting consequences of liabilities for amounts overpaid or deficiencies in payment, which again would be liable to be upset in the following year.
The question befdre the circuit court was whether the evidence before it clearly and satisfactorily showed that the order of August 23, 1912, was unlawful because unreasonable when made. It would doubtless be entirely competent for this court to send the case back to the circuit court to pass upon this question specifically before passing upon it here; but this case has been pending many years and it seems that public and private interests require that there should be as speedy an end of this litigation as possible, and, as the evidence .is all before us, we have concluded to examine it and ascertain whether it justifies the conclusion that the order in question was unreasonable when made. It may be remarked in passing that if it fixed an unreasonably low fare it was unlawful because the fare must be a reasonable fare.
This examination convinces us that it is not shown by clear and satisfactory evidence that the order of August 23, 1912, was unlawful or unreasonable when made. A reasonable rate is a rate which yields a fair return on the value of the property necessarily employed over and above expenses and depreciation, and a return of seven and one-half per cent, has been approved by this court. Duluth St. R. Co. v. Railroad Comm. 161 Wis. 245, 152 N. W. 887.
Reference to the- report of the proceeding which culminated in the order in question here (found in 10 Wis. R. R. *429Comm. Rep. 1-305) will show that the Commission then figured, the company’s total investment in 1911 to- be $10,900,889 and its surplus of income for that year to be $1,436,847.61, making an excess of $619,280.94 over and above a seven and one-half per cent, return upon the investment (p. 243). From this surplus the Commission calculated that there should be deducted a sum not exceeding $416,469 for wage increases, extension of single-fare privileges, and various other losses and increased expenses likely to follow in the near future (p. 247), leaving a net probable surplus for 1912 over and above the seven and one-half per cent, return on the investment of more than $200,000. They then calculated that the reduction of revenue resulting from the sale of thirteen tickets for fifty cents, instead of'twenty-five tickets for $1 as theretofore, would amount to $171,784, which being deducted from the net .surplus would still leave the seven and one-half per cent, return on the investment intact.
The respondent company very vigorously claims that the investment valuation should have been very largely increased. Any detailed or exhaustive treatment of this subject would involve many pages of discussion of facts and tabulation of figures. The subject was treated yery thoroughly by the Commission in its report of the case, covering more than 300 pages, and we shall content ourselves here with saying that the conclusions of the Commission in this respect were founded on ample evidence and cannot now be set aside. The claim that the Commission was bound in its estimate of value by the conclusions reached in the action brought in the federal court in 1898 by the plaintiff against the city of Milwaukee to declare an. ordinance fixing fares confiscatory (87 Fed. 577) cannot be entertained.
When the state asserted and put into operation its power to fix rates and fares by means of the Railroad Commission it manifestly started with a clean sheet and was. not hampered, by the results of any previous litigation between the *430company and the city. Nor was the Commission bound to allow amounts paid by the plaintiff in purchasing the five separate railways of which the plaintiff’s system is composed. Such amounts do not necessarily represent fair or actual values.
It appears by the evidence that in the summer of 1913 the Railroad Commission of its own motion instituted and conducted an investigation with reference to the service on the plaintiff’s city lines, which will be found reported in vol. 13 Wis. R. R. Comm. Rep. pp. 178-245. In their report o'f this case, at page 239, will be found tables showing the earnings and operating expenses of the plaintiff during the years 1912 and 1913. From these tables it appears that they figured the fair value of the property in 1912 at $11,600,000, upon which there was a surplus of earnings, after payment of expenses, of $1,304,798.54, being an excess of $434,798.54 over and above seven and one-half per cent, return on the value; and that in 1913, on a valuation of $12,000,000, the excess over and above the seven and one-half per cent, was $297,803.60. In this case the Commission say (p. 240) : “It is difficult to see in what respects the Commission went further in the Fare Case than was its plain duty under the circumstances.” More .than a year later the Woehsner Case (15 Wis. R. R. Comm. Rep. 724-751) came before the Commission, and at this time there came to the attention of that' body a number of new facts. It is said in this case (p. 734), “the Commission still believes that under the existing conditions and the knowledge at hand up to December 31, 1911, the above rate \i. e. the rate fixed by the order of August 23, 1912] was fair to the contending parties.”
The Commission then proceeds to state the factors which have contributed to the changed conditions which “exist at the present writing” and which in their judgment call for abrogation of the order of 1912. The most significant of these is the additions to the physical property, which during the years from January 1, 1911, to January 1, 1914, *431amounted to $4,512,818, or an increase of forty-three per cent., during which time the gross revenues remained practically stationary at a little more than $4,000,000, in fact showing a slight falling off in 1914 from the previous year. Of these additions about $1,000,000 was expended in 1912 and nearly $1,600,000 in 1913. Other factors noted by the Commission were (1) the increased demands of the city for paving between the tracks, which were $91,611 in 1912 and rose to $358,758 in 1913; (2) the higher relative cost of maintenance of property; (3) the increase in wages of labor, expense of supervision, and overhead charges; (4) the more extended use of transfers by reason of the opening of crosstown lines, causing an estimated loss in revenues for the year 1914 alone of $80,000; (5) the depressing effect of the extensive use of automobiles, causing an estimated loss in revenue in 1914 of somewhere from $122,500 to $245,000; and finally the effect of the order of August 23, 1912, itself.
We shall not attempt to discuss these factors in detail nor do we here intimate that they were sufficient to justify the Commission abrogating the order just referred to at any time. It appears that in 1918, in a proceeding brought before the Railroad Commission by the plaintiff here, an order was made still futher raising the fares on the plaintiff’s lines by ordering the discontinuance of the sale of tickets at the rate of six for twenty-five cents, and the validity of this order has been challenged in an action which is now in this court on appeal and soon to be heard.
It is sufficient now to observe that the evidence does not make it clear that the order of August 23, 1912, was in any respect unreasonable when made. The conditions then existing appear to have quite fully justified the making of the order. The factors which are claimed to have made the rate of fare then fixed unreasonable are changed conditions which came in after the making of that order, principally during the years 1913 and 1914. Whatever may have been the effect of the changed conditions on the question of the *432present reasonableness of the order, they do not establish the fact that it was unreasonable when made.
By the Court. — Judgment reversed, and action remanded with directions to affirm the order of the Railroad Commission, with costs in favor of the city to be taxed against the plaintiff.
