The opinion of the court was delivered by
Eastwood, J. A. D.The Hudson & Manhattan Railroad Company (hereinafter referred to as “the Railroad”) appeals from the final decision of the Board of Public Utility Commissioners, Department of Public Utilities, State of New Jersey (hereinafter referred to as “the Board”), denying the Railroad’s application for an increase of its intrastate fare from five cents to ten cents. The City of Jersey City (hereinafter referred to as “the City”), protested the fare increase and participated in the hearings before the Board.
The Railroad operates an interurban rapid transit electric railroad transporting passengers between points in the States of New Jersey and New York and intrastate within those states. The Railroad asserts that since’1934 it has operated its railroad at a substantial loss; that its deficit from railroad operations for 1949 was $1,986,579.06-; and that its estimated deficit for 1950 is $1,423,978.75. On November 18, 1949, the Railroad filed with the Board its petition for the aforementioned fare increase—its first application for such an increase during its 40 years of ownership. On March 19, *3991950, the Board scheduled a hearing for April 26, 1950, which, after ten sessions, was concluded on August 2, 1950. The Board handed down its decision on February 15, 1951. The Interstate Commerce Commission lias approved an increase of the Kailroad’s interstate fare from ten cents to fifteen cents, and the Public Service Commission of New York has increased the intrastate fare from five cents to ten cents.
In its decision, determination and order, the Board stated, inter alia:
‘‘While the record contains exhibits purporting to show the investment in tile property as a whole, devoted to interstate and intrastate service, the exhibits are compiled from the books of account of the Company. No evidence in support of the book entries was introduced. We are asked to accept the entries in the books of account of the Company at face value. This we cannot do under the above quoted Decision. (Public Service Coordinated Transport v. State, 5 N. J. 19 ((1950)). (Parenthesis ours.)
Neither evidence of the cost to reproduce the property at the time of the inquiry nor other evidence, on the basis of which a ‘property valuation’ might be established was introduced.”
Tiie Eailroad contends now, as it did consistently before the Board, that:
‘‘The Public Service decision is definitely not applicable to the Hudson and Manhattan Railroad, which has been a deficit carrier for more than 1en years. It is limited to cases where a utility asserts a need for the revenue because it wants a fair return, not to supply revenue to meet costs.
The Public Service decision was upon facts and contentions related to the reasonableness of the rate or amount of return whether equated to stock or properly value (supra, 5 N. J. 223). The Court holds that adequate proof and finding of rate base are essential to a valid conclusion on the reasonableness of the return prior to fixing fares. In the present case, the segregated revenues and expenses applicable to the intrastate New Jersey service showed a long continued absolute loss on the forty-year old original five-cent fare. It follows that no test of rate of return is involved and hence no use exists for a current segregated rate base.
The special deficit theory that should be applied to the Appellant is simply that a rate base need not be made out if the record by competent and adequate proof establishes the revenues, operating expenses, rentals, fixed charges such as interest costs, the reasonableness of such expenses and the failure of revenue estimated to result from the *400increased fare to exceed them. The basis for the theory is obvious: With no return possible, there can be no question of the fairness of the return. Therefore, no rate base is necessary.’’
In its reply brief, the Railroad asserts:
“In view of the deficit under present and proposed fares, finding of a rate base is not necessary, but if required, adequate data were before the Board for the determination of a minimum rate base.”
In considering the pivotal issue here, we are convinced that the Public Service case, supra, is controlling. See also Central R. Co. of N. J. v. Dept. of Public Utilities, 7 N. J. 247 (1951). That such a conclusion is warranted clearly appears in the following language of Chief Justice Vanderbilt in the Public Service case, supra:
“* * * The statutory standard prescribing the rate-making powers of the Board is to be found in R. S. 48:2-21 (5) (1) which provides that the Board may ‘Fix just and reasonable individual rates * * * whenever the Board shall determine any existing rate * * * to be unjust, unreasonable, insufficient or unjustly discriminatory or preferential.’ In any case in which the reasonableness of the fixed rate is challenged and the fulfillment of the statutory standard thereby subjected to judicial review, the court is duty bound to weigh the evidence and resolve for itself the issue of reasonableness.
ífe >¡C Sj* Jj« S»t :{;
The justness and reasonableness of a particular rate of fare can only be determined after an examination of a company’s property valuation which constitutes its rate base; its expenses, including income taxes and an allowance for depreciation; and the rate of return developed by relating its income to the rate base.
s{t * * * * * * *
The determination of an adequate rate base is, as the term applies, fundamental in any rate proceeding. The rate base is the fair value of the property of the public utility that is used and useful in the public service.”
But, the Railroad argues, there was “adequate data * * * before the Board for the determination of a minimum rate base.” The City contends that the only proof adduced by the Railroad were its books of account and records; that it failed to introduce evidence in support thereof in conformity with the holding of the Public Service case, supra, to wit:
*401“The dangers inherent in accepting the books of account at face value in a rate proceeding are apparent. The prescription of a uniform system of accounts by regulatory commissions, such as the Board of Public Utility Commissioners, has been uniformly accompanied by the qualification that in prescribing the system of accounts, the commissioners do not commit themselves to the approval or acceptance of any item set out, in any account for the purpose of fixing rates or in determining other matters before the commission.
Neither this Court nor the Board can accept the books of account of a public utility at face value in a rate case in which reasonableness is always the primary issue.
* * * There must be proof in the record not only as to the amount of the various accounts but also sufficient evidence from which the reasonableness of the accounts can be determined. Indeed, R. S. 48:2-21 (d) specifically provides that ‘The burden of proof to show that the increase, change or alteration (in rates) is just and reasonable shall be upon the public utility making the same.’ Backing such evidence, any determination of rates must be considered arbitrary and unreasonable.”
“It is well recognized that rate-making is a legislative and not a judicial function, and that the Board of Public Utility Commissioners, to which the Legislature has delegated its rate-making power, is vested with broad discretion hi the exercise of that authority. O’Brien v. Board of Public Utility Commissioners, 92 N. J. L. 44 (Sup. Ct. 1918) ; affirmed 92 N. J. L. 587 (E. & A. 1919) ; Atlantic City Sewerage Company v. Board of Public Utility Commissioners, 128 N. J. L. 359 (Sup. Ct. 1942) ; affirmed 129 N. J. L. 401 (E. & A. 1943). For the delegation of the legislative function to be valid under our Constitution it is essential that adequate standards be prescribed by the Legislature and adhered to by its agent, in this instance the Board. Van Riper v. Traffic Telephone Workers’ Federation of New Jersey, 2 N. J. 335 (1949); State Board of Milk Control v. Newark Milk Co., 118 N. J. Eq. 504 (E. & A. 1935).” Public Service Coordinated Transport v. State, supra. The Railroad contends that its objective was to obtain a rate of fare based on its “deficiency theory” and it was not seeking a fare that was intended to yield a return to the stockholders; there*402fore, the Public Service case was not pertinent. With that contention we are not in accord. In view of the position taken by the Railroad at the hearing and the Board’s contention that the Public Service case was controlling, it is unfortunate that it did not insist upon the Railroad producing proof in support of its books and records so that a rate base might be established. It may well be that the Railroad is entitled to some relief. However, the determination of that question remains for the resolution of the Board. R. S. 48:2-47 authorizes the court, where it shall appear equitable and just, to order a rehearing before the Board “upon such terms and conditions as are reasonable,” and “The board shall thereupon proceed to a rehearing on the evidence upon which the order under review was based, and upon such additional evidence, if any, as may be produced. As the result of the rehearing the board may readopt the order or alter, amend, modify or extend it.” In the Central B. Co. case, supra, Mr. Justice Burling, speaking for the Supreme Court, stated:
“* * * We are now presented with the question whether upon a formal rehearing an administrative agency, vested with powers partaking of both legislative and judicial attributes, should consider the record of the original hearing as well as the evidence submitted to it during the course of the rehearing.
There is ho doubt in our minds that the Board must consider the entire record, including the records of both the original hearing and the rehearing. Compare Public Service Coordinated Transport v. State (p. 213), supra.”
Por the reasons above stated, the order of the Board of Eebruary 15,1951, is set aside and the record and proceedings are remanded for rehearing on the evidence upon which that order was based, as well,as upon such additional evidence as may be introduced. The rehearing should be fixed at a reasonably early date and the issue determined as expeditiously as possible.
