In Gene Slagle, Inc., v. Pub. Util. Comm., supra, at page 46, it was held that when an order of the commission changing utility rates has been reversed by this court for failing to adequately set forth the reasons prompting the decision, “the increased rates pursuant to such order could no longer be lawfully charged, and those fates in effect prior to the above order were reinstated by operation of law, and continued in effect until further order of the commission.” The utility raises two issues in this case: whether Slagle applies to this court’s decision in Cleveland Elec. Illuminating Co. v. Pub. Util. Comm. (1975), 42 Ohio St. 2d 403, 330 N. E. 2d 1, and whether Slagle was erroneous and should be overruled. Since the utility-raises substantial questions as to the correctness of Slagle itself, we find it appropriate to begin our consideration with that issue.
I.
The difficulty presented in this case and in Slagle is that the statutory plan for public utility regulation set out in Title 49 of the Revised Code does not specifically prescribe' the immediate effect upon existing rates of this court’s' reversal .of a commission order revising rates; nor do the statutes prescribe a particular procedure to be fol-' lowed. . i '
The process of public utility rate-making in Ohio isi wholly controlled by statute. Any public utility desiring to< establish a rate or to change an existing rate must file ai written application with the commission. R. C. 4909.18. The duty of the commission is to determine the justness *108and reasonableness of the proposed rates, based upon the valuation of the utility’s property, giving due regard to relevant factors such as the necessity for making reservations for surplus, depreciation and contingencies, and such other matters as are proper according to the facts of each case. R. 0. 4909.15.
The process of rate-making frequently involves extensive hearings, voluminous testimony, and the determination of difficult and abstruse technical questions which must be resolved on the basis of complex and often disputed evidence. The function of the commission is to carry through this process, in accordance with the statutory plan, and to fix lawful and reasonable rates based upon the evidence presented.
The function and jurisdiction of this court in an appeal from an order of the commission is limited. Under R. C. 4903.13, our task is to affirm an order of the commission if it is not unreasonable or unlawful. This court has often emphasized the limited nature of that authority.1
Our function is not to weigh the evidence or to choose between alternative, fairly debatable rate structures. That would be to interfere with the jurisdiction and competence of the commission and to assume powers which this court is not suited to exercise. ‘ ‘ * * # The members of this court are neither accountants nor engineers, and manifestly it would be unfair to the litigants and to the commission for the court to pretend that it is in a position to better evaluate the evidence and determine the difficult question of the reasonableness of the order than is the commission.” Dayton v. Pub. Util. Comm. (1962), 174 Ohio St. 160, 162, 187 N. E. 2d 150. Our task is not to set rates; it is only to assure that the rates are not unlawful or unreasonable, and that the rate-making process itself is lawfully carried out.
*109In large measure, the purpose of the decision in Slagle was to affirm the limited nature of this court’s jurisdiction in these types of cases. Our decision was that this court’s reversal of a commission order rendered that order of no further legal effect. Upon a literal reading of the duties of this court under R. C. 4903.13, that decision is a logical result, for the statute directs that the order be “reversed, vacated or modified” if found to be unreasonable or unlawful.
The order which this court reversed in General Telephone Co. v. Pub. Util. Comm. (1972), 30 Ohio St. 2d 271, 285 N. E. 2d 34, and which was later at issue in Slagle, was an order which was defective because the commission had failed to carry out its statutory duty to provide adequate findings of fact and conclusions of law. This court could not modify the order without indulging in extensive examination of the record and improper speculation as to the actual basis for the decisions made by the commission, nor could this court determine that the order was based upon the evidence. Upon a literal reading of R. C. 4903.13, it would appear that this court might only reverse or vacate the order, in the sense of ending the order’s legal effect, while leaving any subsequent proceedings for remedying defects in the order to the judgment of the commission.
In fact, however, upon further reflection and examination of Ohio’s statutory plan for public utility regulation, and of the principles upon which this court’s jurisdiction is based, we are now convinced that our decision in Slagle was in error and must be reversed. Several considerations compel this conclusion.
I A.
The opinion of this court in General Telephone reversed the order of the commission,2 and in CE1, supra (42 Ohio *110St. 2d 403), we reversed in part and affirmed in part. In both cases, this conrt remanded the. canses to the commission. ..
To “remand” is to send a canse back to .the original tribunal for -further proceedings, generally upon orders or directions from the higher court. "When a court acts to remand a cause,- it is not itself finally determining the outcome of the cause, nor is it executing a judgment in favor of one of the parties.3 The judgment is given legal effect when it is executed by the lower tribunal, and the judgment as rendered is that of the tribunal to. which the cause had been remanded. Carey v. Kemper (1887), 45 Ohio St. 93, 11 N. E. 130. Since the effective, final .judgment upon re7 mand is that of the lower tribunal, it is. manifest that this' court’s judgment does not. take effect as a matter of Jaw. In Roberts v. Montgomery (1927), 117 Ohio St. 400, 159 N. E. 475, this court was .called upon- to interpret Section 2 of *111Article IV of the Constitution, which, then as now, confers the jurisdiction of this court in terms virtually identical to R. C. 4903.13, i. e., jurisdiction to “review and affirm, modify, or reverse” the judgment. The court held, in paragraph one of the syllabus, that the authority of this court to remand is “* * * a necessary concomitant of the jurisdiction to review, affirm, modify, or reverse.” That decision concerned an appeal from a Court of Appeals, but the same principle must apply here, since virtually identical jurisdictional language is involved. The holding in Roberts v. Montgomery, supra, necessarily affirms that this court has authority to remand causes to the commission.
That conclusion is also supported by other authority and by accepted practice.
In Ford Motor Co. v. Labor Board (1939), 305 U. S. 364, it was held that a federal Circuit Court of Appeals had inherent authority to remand a cause to a federal board, based upon statutory provisions for review similar to those at bar.4 This court has also frequently recognized and exercised the authority to remand cases to administrative boards. In Superior Metal Products v. Admr., Bur. of Employment Services (1975), 41 Ohio St. 2d 143, 146, 324 N. E. 2d 179, it was stated: “This court holds that the power to reverse and vacate decisions necessarily includes the *112power to remand the cause to the decision maker.” The same principle has been applied to various other types of cases,5 and. has been applied as well in order to remand cases, for further proceedings even without reversal of the decisions below. McDowell v. State (1929), 120 Ohio St. 613, 169 N. E. 299; Young v. Schenck (1856), 6 Ohio St. 110.
This court has impliedly recognized the existence of such authority in appeals from the. commission on numerous occasions.6 We have also specifically held that this court has the authority, and even in some cases.the duty, to remand causes to the commission. In East Ohio Gas Co. v. Pub. Util. Comm. (1938), 133 Ohio St. 212, 12 N. E. 2d 765, paragraph thirteen of the syllabus states
“Where the court determines that certain findings of the Public Utilities Commission are unreasonable and unlawful while others were properly made, and from the record the court is unable to substitute specific findings for those improperly made by the commission, it is the duty of the court to remand the proceedings to the commission, as a fact finding body, with, instructions to carry out the rulings of the court and correct the. findings which were found to be unreasonable and unlawful. ”
All of these considerations conclusively establish that this court does possess the authority to remand causes to the commission, as we did in both General Telephone, supra (30 Ohio St.'2d 271), and CE1, supra.
As was pointed out above, the effective judgment upon remand is the judgment of the lower tribunal. See R. C. *1132505:37 ;an.d¡ 2505,39. That principle applies to. orders of the commission,; -and it therefore follows that the execution of: this, court’s judgment of reversal - and, remand occurs only when, the; commission carries out the- mandate; of thin court by its,order and not, as held in Slagle., at-the moment of this, court’s reversal by operation of law. ■ . : .
IB.
■ In Cincinnati & Suburban Bell Tel. Co. v. Pub. Util. Comm. (1923), 107 Ohio St. 370, 140 N. E. 86, this, court specifically’,held that the. reversal and remand of-a- rate schedule : did-.not act to • automatically reinstate ■ the rates theretofore, in,force. The'court, at page 374, stated:
“ *.*■•* Therefore, when- the order -of the Public Utilities Commission was reversed by this court, and the ■cause remanded generally for further proceedings according to law, the. cause came again before the;Public Utilities Commission.for the exercise by it of.its judgment, apd, .if the record before it was not sufficient to enable it. to intelligently exercise' such judgment, it was its- duty to either itself -supplement that record or permit- the parties interv usted to make such supplement, and then base its conclusion upon such record.”7
■ -Thecircumstances of that case were unusual, as pointed out -in Sldgle. The reversal of the rate schedule was or-i defed- Without’ an accompanying, majority opinion by the court. Nevertheless, the court did recognize the authority to. remand.cases to the commission, and. recognized, as well, that, the reversal and remand did not act to automatically reinstate- thé .previous rate schedule.. ’ ■ ,
-' : A similár, issue was presented in Keco v. Cincinnati & Suburban Bell Tel. Co. (1957), 166 Ohio St. 254, 141 N. E. 2d 465: Ip that!-case, the issue Was whether an .action .for unjust enrichment lies, to- recover an increase in -rates charged by a public utility under -an order of the eommis-f *114sion, where the order is subsequently reversed by the Supreme Court on the grounds that it is unreasonable and unlawful. The court, in Keco, held that an action for restitution did not lie. For the present purposes, it is significant to note t'he dates involved—the increase in rates was granted by an order dated May 28, 1953; on May 25, 1954, this court reversed and remanded the cause; and on June 4, 1954, the commission issued its order reducing the rates. The appellant sought restitution for the period from May 28, 1953 to June 4,1954. Thus, this court’s dismissal of the entire claim to a right of restitution necessarily held that the original rate order remained in effect during the period after this court’s reversal and before the commission’s new order.
The opinion in Keco did not specifically consider the moment at which this court’s reversal and remand of a commission order takes effect, so that the case cannot be considered binding precedent on the issue herein. Nevertheless, that case and the Cincinnati £ Suburban Bell case, supra (107 Ohio St. 370), are persuasive authority and are the only cases on point in Ohio.
1 C-
Most importantly, the holding in Slagle is incompatible with the statutory scheme for regulation of public utilities established by the General Assembly in Title 49 of the Revised Code.
The basic principle of Ohio’s regulatory scheme for uti'ifv ra.tc« is that those rates are to be set by the commission upon hearings and evidence, and that only those rates which have been found to be fair and reasonable after such hearings may lawfully be charged. Utilities are protected by being assured a fair rate of return, while consumers are protected by being assured that service will be adequate and rates reasonable.
The rates fixed by order of the commission then go into.effect immediately unless stayed by the. filing of a •bond during an appeal, and the order establishes the only .rate which the utility may lawfully charge.
*115The. basic, argument in support of the position in Slagle isthat when this court reverses a commission order approvirig a revised rate schedule, the order, and the schedule are then no longer in effect. Therefore, it is argued that B.. C. 4905.32 ¡applies, which provides that: ,
“Ño-;public utility shall charge, demand, exact, receive, or collect-a different rate, .rental, toll, or charge for.any service rendered,, or to be rendered, than that applicable to such service as specified in its schedule filed with the Public Utilities Commission which is in effect at the, time. ’ ’
There are. fundamental practical and statutory objections to. that, construction of the statute., The logical result of that-argument would be that no rate could be charged, since this court had struck down the only rate schedule which was filed and. in effect with the commission. That result would of , course be manifestly unfair and , perhaps disastrous, for .-the unlucky utility.. In other, states, it .has accordingly been held.that the utility in .such, cases.has a right to charge a reasonable rate. Arizona Corp. Comm. v. Mountain States Tel. & Tel. Co. (1951), 71 Ariz. 404, 228 P. 2d. 749; Southern Bell Tel. & Tel. Co. v. Georgia. Pub. Serv. Comm. (1948), 203 Ga. 832, 49 S. E. 2d 38; Hutchinson v. Hutchinson Gas Co. (1928), 125 Kan. 346, 264 P. 68; 73 Corpus Juris Secundum 1010.
_ Presumably, it. was in order to. prevent such an imr permissibly-..burdensome. result ,that Slagle adopted the principle, that’ the effect of reversal was to reinstitute the rates charged by the utility before the order complained :.of. But those .-rates, are ones the commission has rejected as.unreasonable. That .act might b.e based upon some legal fiction that the old 'rates are still constructively or. presumptively filed. Yet, the.practical effect is that this court would bo directly ordering a utility to charge rates found to be unreasonable by the commission, rates which differ from those actually-on file and which are only marginally and technically more defensible than any other past rate schedule.
The statutory framework for utility rate-making, conflicts with such a holding. Various statutes require that *116public utility rates “shall be just, reasonable, and not more than the charges allowed by law or by order of the Public Utilities Commission” (B. C. 4905.22); that a utility’s rates shall hot differ from those “specified in its schedule filed with the Public Utilities Commission which' is in effect at the time” (B. C. 4905.32); and that if the utility “does or causes to be done, any act or thing * * * declared to be unlawful” it is liable in treble damages to the person, firm or corporation injured thereby (B. C. 4905.61).
\ The heart of this statutory plan is that the only proper rate is that set out in the approved rate schedule on file with the commission and open to public inspection, and that this schedule can be chánged only by an order of the commission. ' ■ '' ■ • ■ “
B. C, 4909.17 provides, in part, that:
1“No rate, joint rate, toll, classification, charge, or rental, no change in any rate, joint rate, toll, classification, Charge, or rental, and nó regulation or practice affecting any rate, joint rate, toll, classification, charge, or rental of a public utility’ shall become effective until the Public Utilities Commission,' by order, determines it'to bb júst and reasonable *■* ■
Even more specific is B. C.' 4909.15, which-provides, in part, that after the commission has ordered’that a new ‘fate be substituted' for an existing one “ * * * no change in the rate, fare, toll, charge, rental, schedule,'classification, or service, shall he made, rendered, charged, demanded, exacted, of changed hy such public utility without the order of the'commission, and any other rate, fare, toll, Charge, rental, classification, or service is prohibited J’
/ For this court to require, upon penalty of treble damages, that a public utility change its rates before the commission itself has ordered a change, would he to f eqúiré the Utility to directly violate B. C. 4909.15. ....
Ño such result was intended'by the General Assembly in its delineation of the authorities of the commission and of thiá'cóúrt. Bather, the státutes make clear that-public ■ Utilities are'required to'charge the'rates andfees' stated' in the schedules filed with the commission pursuant to the *117commission’s orders; that the schedule remains in effect until replaced by a further order of the commission; that this court’s reversal and remand of an order of the commission does not change or replace the schedule as a matter of law, but is a mandate to the commission to issue a new order which replaces the reversed order; and that a rate schedule filed with the commission remains in efféct until the commission executes this court’s mandate by an appropriate order. This holding is consistent with the basis Of this court’s jurisdiction, with precedent and established practice, and with the statutory framework for public utility rate-making.
I D.
The difficulty which today’s holding does pose is that the customers of public utilities may be charged a rate found by this court to be unreasonable or unlawful during the period preceding the execution of this court’s mandate by an order of the commission. There are a number of answers to this difficulty.
First, the “unfairness” is often merely technical or wholly illusory. In both General Telephone and GE1, supra, it was the utility which appealed the rate orders. In the former case, the order was found by this court to be technically insufficient, but upon remand the commission reinstituted exactly the same rates which it had originally found reasonable. Slagle, supra. There is no apparent unfairness in charging that same rate in the brief interim period. In CE1, this court found that the rates granted were too low, so that any delay in adopting a new rate schedule would tend to continue rates which this court had found to be unreasonably low. If there is any unfairness in this, it is to the utility and not'to the consumers.
Second, even in cases where this court finds that rates should be reduced, the commission has a clear responsibility to do this promptly. If it becomes apparent that there will be a long delay in establishing new rates, the commission also has authority to temporarily alter rates under the emergency powers of R. C. 4909.16.
Third, the practical problems of administering rate *118hearings and appeals therefrom necessarily cause delays, and there is simply no way that an-immediate and perfect modification of utility rates can-be achieved.-The language quoted with approval in Keco,, supra (166 Ohio St.), at page 259, applies with equal force in this case:
“It may seem inequitable to permit the defendant to retain the difference in the. rates-collected under the May 28, 1953, order of the commission and the rates finally fixed by the commission on June 4, 1954, but absolute equity in a particular case must sometimes give way to the greater overall' good. In adopting a comprehensive scheme- of public utility rate regulation, the Legislature has found. it impossible to do absolute justice under all circumstances. For exámple, under present-statutes a utility may not charge increased rates during proceedings before the commission seeking same and losses sustained thereby may not be recouped. Likewise, a consumer is not entitled to a refund of excessive rates paid during proceedings before the commission seeking a reduction in rates. Thus, while keeping its broad objectives in mind, the Legislature has attempted to keep the equities between the utility and the consumer in balance but has not found it possible to do absolute equity in every conceivable situation.”
II. --
'• - As mentioned above, appellant has- urged that the present case is distinguishable from Slagle, because in that ease the entire order of the commission was struck down for failing to comply with the statutory requirements as to the form of an order, whereas in this case the order was formally sufficient, but was reversed in part because this court found that some of the commission’s findings were unreasonable and unlawful. That distinction would have the paradoxical effect of permitting a utility to charge rates after this court had in fáct found them to be unreasonable and unlawful, but, under Slagle, of forbidding the utility to charge rates which the commission had found to be reasonable and which this court had not actually even considered. In any event, since we find that the rule itself is faulty, *119we need not further consider whether an exception to it should be adopted.
We also need not address the constitutional issues raised by the appellants.8
III.
We hold that the rates in effect for appellant prior to the commission’s November 28, 1973, opinion and order were not reinstated by operation of law when this court reversed that order in part. The June 16,1975, order of the commission, which so held, is unlawful and it is therefore reversed.
Order reversed.
O’Neill, C. J., W. Brown and P. Brown, JJ., concur. Herbert, J., concurs in the syllabus and the judgment only. Corrigan, J., concurs in paragraph two of the syllabus and in the judgment. Celebrezze, J., concurs in paragraph one of the syllabus only.E. g., Ohio Bus Line v. Pub. Util. Comm. (1972), 29 Ohio St. 2d 222, 280 N. E. 2d 907; Akron v. Pub. Util. Comm. (1966), 5 Ohio St. 2d 237, 215 N. E. 2d 366; Mt. Vernon Tel. Corp. v. Pub. Util. Comm. (1955), 163 Ohio St. 381, 127 N. E. 2d 14; Ohio Bell Tel. Co. Pub. Util. Comm. (1951), 155 Ohio St. 526, 99 N. E. 2d 653; Cincinnati v. Pub. Util. Comm. (1950), 153 Ohio St. 56, 90 N. E. 2d 681.
In General Telephone, the syllabus and opinion stated that the order was tto be set aside. “Set aside” and “reverse” are, or course synonomous, both meaning to annul or make void. For example, “reverse” is defined in Black’s Law Dictionary (4 ed.) as “to overthrow, vacate, set aside, make void, annul, repeal, or revoke * * (Emphasis added.)
For example, R. C. 2505.37 provides that:
“When a judgment or final order is reversed, in whole or part, In' the' * * * Supreme Court; the reviewing court-shall render such judgment as .the.court'below should-have rendered,.or remand the cause to that court for such judgment.” ' ■ .
And,.R. C. 25Q5.39 provides tpat: ,
“A court which reverses or affirms a judgment or final order upon appeal on questions ' of ’ law, on which ’it pronounces ’ judgment,' shall not 'issue execution therein, but' shall send a • special • mandate to the court below for execution thereon.” 1 '■ ■
... This latter statute 'by its .-terms applies-to appeals-from-, courts, and does .not mention administrative.agencies. However,.R.- C.-'¡Chapter 2505, which sets out the procedure on appeals, applies to “all proceedings whereby one cburt reviews or retries a cause determined by another court, -an "administrative- officer, tribunal, or commission” - (R. C. 2505.0.1 [A])’•; and R. C. 2505.03 specifically provides that: . ••
“Every final order, judgment,-or decree of a court and, when provided by law, the final order of any administrative officer, tribunal, or commission may be reviewed as provided in Sections 2505.04 to 2505.45, inclusive, of the Revised Code, unless otherwise provided by law. * * *”
' Present R. C. Sections 2505.01, 2505.03, 2505.37, 2505.39, and 4903.13 were all enacted or reenacted in 1935, in an Act to Establish a Simplified Method of Appellate Review (116 Ohio Laws 104). This procedural scheme might arguably be held to apply to appeals from the commission, since no other procedure is provided by law, but that question is not «directly presented here.
The statute in that case provided that “* * * the court * * * shall have the same exclusive jurisdiction to grant to the board such temporary relief or restraining order as it deems just and proper, and in like manner to make and enter a decree enforcing, modifying, and enforcing as so modified, or setting aside in whole or in part the order of the board * * The court there stated, at page 373, that:
“It is familiar appellate practice to remand causes for furtheg proceedings without deciding the merits, where justice demands that course in order that some defect in the record may be supplied. Such a remand may be. made to permit further evidence to be taken or additional findings to. be made upon essential points.”
And, at page 374, the court stated that:
“The ‘remand’ does not encroach upon administrative functions. It means simply that the case is returned to the administrative body in order that it may take further action'in accordance with the applicable law.” (Citations omitted.)

This opinion has been a lengthy one. Its intent was to make fully clear why this court today overrules an opinion rendered without dissent only a year ago. This, court is more accustomed to detecting and correcting the errors of others than its own. It is to be hoped that we will always remain willing to correct them whether found in either place.
