delivered the opinion of the Court.
A writ of certiorari brings to this Court for review a judgment[1] of the Circuit Court of Appeals for the Fifth Circuit denying the validity or applicability of the following section in a franchise granted to respondent by petitioner in 1930. Section IX of that franchise reads as follows:
“If Grantee shall be finally compelled to, or should voluntarily, place [sic] in any rates in the City of Texar-kana, Arkansas, less than the rates granted by this Ordinance then and thereupon the lessened rate shall apply in the City of Texarkana, Texas, and Grantee shall not be authorized or permitted to charge and collect any higher rate.”
Texarkana, Texas, and Texarkana, Arkansas, are adjacent cities divided by the Arkansas-Texas state line. Respondent serves as a public utility for the distribution of gas in

The charter of the Texas city gives authority to grant franchises for the use of its public ways upon terms to be embodied in ordinances, which must expressly provide that the city shall retain the regulation of the business of the utility, the fixing of its rates and the right to inspect its operations. Should these reservations be omitted, they are nevertheless to be considered part and parcel of the franchise.[3] The charter also provides that the city, shall have the power to regulate rates charged by gas com-

3 Sec. 160. “The rights of the City of Texarkana in the use of the public streets, alleys, squares, parks, bridges and all public places are hereby declared to be inalienable to any person, firm or corporation, except by license permit and franchise passed by the city council on the affirmative vote of three-fifths of all the members of said council elected.” Sec. 163. “Said proposed franchise shall contain all the terms and agreements between the parties thereto, and it must expressly set forth that the council shall have the right and privilege of regulating and controlling the operation of all business done thereunder, fixing fares, rates, tolls and charges and inspecting the business and work from time to time as it progresses, and rate regulations shall conform to Section 197 of this charter.” Sec, 163a. “In the event that any franchise or permit is so given by said council, which shall not contain such stipulations therein as provided for in Section 162 of this charter, then it shall, nevertheless, be considered that all of the said stipulations contained in said Sections 162, 163 and 197 are part and parcel of the said contract and franchise, just as though written therein, and the said applicant so accepting such franchise, as well as their heirs, assigns and successors, shall be held and firmly bound thereto, notwithstanding such omissions.”
On May 30, 1930, the gas company secured a similar arrangement adjusting rates from the Arkansas city. There had previously been in effect a franchise of 1923 with rates substantially identical with the Texas 1923 rates. The Arkansas franchise of 1930 was subjected to a referendum and to prolonged litigation. Eventually, on December 1, 1983, a final order set aside the 1930 ordinance of the Arkansas city and established the rates of the 1923 ordinance as effective for the consumers of the Arkansas city from 1930 to the date of the decree. This
4 Sec. 196. “That the city council shall have the power to regulate by ordinance the rates and compensation to be charged by all water, gas, light and telephone companies, corporations or persons using the streets and public grounds of said city and engaged in furnishing water, gas, light and telephone service to the public, and to prescribe reasonable rules and regulations under which such commodities shall be furnished and services rendered, and to fix penalties to enforce such charges, rules and regulations; provided, that the city council shall not prescribe any rate or compensation which will yield less than ten per cent per annum net on the actual costs of the physical properties, equipments and betterments. Said city council may also fix the charges which may be collected for transporting passengers and baggage in vehicles engaged in public service.”
In Texarkana, Texas, the consumers have paid, since 1930 the rates fixed in that ordinance, which are substantially higher than those finally determined as applicable to the Arkansas consumers. The gas company in October, 1933, sought from the Texas city council rates still higher than those granted by the 1930 ordinance. The company gave notice that on November 23, 1933, a new and higher schedule of rates than those provided in the 1930 agreement would be established in the Texas city. The Texas city sought and obtained in the state court an injunction against this increase. This is still effective. This suit was removed to the federal district court for Texas. The bill was amended on January 15, 1934, to set up an additional cause of action against the gas company by reason of the entry of the decree on December 1,1933, in the Arkansas litigation. As this decree was a final order determining that the Arkansas consum

The situation from the standpoint of the Texas city might be summarized by saying that it seeks for its consumers the lower 1923 Arkansas rates instead of the Texas 1930 rates, from the effective date of the Arkansas, resolution of May 30, 1930, to February 16, 1934. This refund is claimed because the Arkansas consumers obtained these lower rates by the Arkansas decree of December 1, 1933, and the voluntary act of the gas company in collecting the lower rates from the date of the decree to February 16, 1934. On final affirmance of the Arkansas litigation, it seeks refunds for its consumers from February 16, 1934, to December 4, 1936, of the difference between the Texas 1930 rates and the Arkansas December 22, 1933, rates.-' This refund is claimed because of the decree of December 4, 1936,[7] validating for the Arkansas consumers the rates of the 1933 resolution. These rates were sub

Another bill was filed by the Texas city in May, 1934, seeking substantially the same relief as that sought in the proceeding heretofore detailed. The reasons for the filing of this second suit and its purpose are not material to the present proceeding. The two actions were consolidated. Later motions, pleadings and the decree in the two cases are the same.
The gas company filed answers.to the bills set out above and a counterclaim seeking higher rates. Section IX was challenged as invalid because of conflict with the provisions of the city charter, the laws and constitution of Texas. It was asserted that the section was not a binding contract on either party to the franchise and further asserted that if § IX was valid, it was inapplicable to any of the three periods for which the Texas city sought relief and refund. The district court granted the city’s motion to strike the answers and counterclaim and, the gas company declining to amend, decreed that § IX was a binding contract between the parties; that it was inapplicable to the period prior to December 1, 1933; that refund should be made from December 1, 1933, to February 16, 1934; and that the suit was premature as to the period after February 16, 1934, because an appeal was pending in the Circuit Court of Appeals for the Eighth Circuit at the time the second amendment was filed by the Texas city on December 30, 1936. The Circuit Court of Appeals reversed and remanded with directions to dismiss
Abdication or delegation of regulatory power. By the act to incorporate the city of Texarkana, Texas, the legislature granted a special charter which contained delegations of power to the municipality to contract for utilities and to regulate gas rates, and prohibitions against the granting of a franchise without specific reservation of this power of future regulation.[9] The respondent takes the position that since § IX not only requires the application of lower Arkansas rates to Texas consumers but provides that the gas company “shall not be authorized or permitted to charge and collect any higher rate,” the Texas city has abdicated power to raise the Texas rates above the Arkansas rates. As the Texas city is forbidden to give up the power to regulate rates, the section, says the company, is invalid.
The city agrees that any delegation or abdication of complete power to regulate rates would be unlawful and any provision of a franchise leading to that result invalid under the decisions of Texas.[10] It is the petitioner’s po

9 The provisions are set out in notes 3 and 4, supra.
10 Uvalde v. Uvalde Electric & Ice Co., 250 S. W. 140 ; Texas Gas Utilities Co. v. Uvalde, 77 S. W. 2d 750 ; Nairn v. Bean (Com. 1932), 48 S. W. 2d 584 , 586; cf. Railroad Cornm’n v.

Nor, in this view, can it be said there is delegation as distinct from abdication of the power to regulate. It is true, extra-state action determines that the rate shall lessen, but the council has power over the rates at all times. The Arkansas rate is a mere measuring rod, as though the rate fluctuated with temperature or consumption. Even if § VIII-A[11] is valid!, in the face of §§ 163, 163a and 196 of the charter, it is inapplicable, by its terms, to the power of the'.city to increase rates.
The obligation of the utility under section IX." As the lower court determined § IX is wholly invalid as a delegation and abdication by the city of its rate making powers, there was no occasion for it to consider whether the
11 Section VIII-A. “In consideration of the granting of this franchise, it is mutually agreed and understood by and between the parties hereto that before the City Council of said City shall apply for a reduction in rates, or before the Southern Cities Distributing Company, its successors or assigns, shall make application for an increase in rates, either party shall give to the other party one year’s notice in writing of its intention to so apply for an increase or decrease in rates, and no application for increase or decrease in rates shall be acted upon or considered unless said one year’s notice is first given before making such application.”
It cannot be said that any opinion of the Supreme Court of Texas settles the problem of whether a utility is bound to a contract for a schedule of rates when the municipality is not. That court, in 1925, in Dallas Railway Co. v. Geller, did state that an ordinance on rates is a contract.[16] There had been a franchise with a fixed

18 It was slated in petitioner’s brief and not denied that after the decision in Uvalde v. Uvalde Elec. & Ice Co., 250 S. W. 140 , discussed in the next paragraph, briefs were filed in the Supreme Court in the Geller case arguing the effect of the Uvalde decision.
19 Lower Colorado River Authority v. McGraw, 83 S. W. 2d 629 , 638; 125 Texas 268 .
The case of Uvalde v. Uvalde Electric & Ice Co., 1923,[20] is suggested as an authority against interpreting a rate contract, invalid as to the city, as binding upon the utility. Uvalde, without power to contract for rates, did so contract. The utility raised the rates without permission. The court was of the view that “the power to regulate rates and the power to stipulate by contract for a term of 10 years for rates, cannot coexist.” Looking at the contract in this way and without discussion of the effect of the attempted agreement on the utility, an injunction against the new rates was refused. That case appears rather a precedent for the rule that where a city is not authorized to contract as to rates but only to regulate them, any effort to contract is nugatory. As indicated above, it has been cited by the Supreme Court of Texas as authority for the right of a municipality to contract when so empowered.
.This Court has had other occasions to consider the rights of Texas utilities under the provisions of the Texas statutes and constitution. In San Antonio Traction Co. v. Altgelt[21] we assumed a rate contract between the city and the street railway, and ruled that it was subject to
20 250 S. W. 140 . Compare Texas Gas Utilities Co. v. Uvalde, 77 S. W. 2d 750 , 752.
These conclusions of this Court are inapplicable here for two reasons: first, the subsequent opinion of the Supreme Court of Texas in the Getter case indicates that regulatory and contract power may be exercised concurrently in that state; second, the charter of Texarkana, Texas, gives it specific power to enter into franchise agreements with rate regulation reserved to the city.[25] The
22 Constitution of State of Texas, Bill of Rights, Vernon’s Texas Statutes 1936, Art. I, p. XXV, § 17. “No person’s property shall be taken, damaged or destroyed for or applied to public use without adequate compensation being made, unless by the consent of such person; and, when taken, except for the use of the State, such compensation shall be first made, or secured by a deposit of money; and no irrevocable or uncontrollable grant of special privileges or immunities, shall be made; but all privileges and franchises granted by the Legislature, or created under its authority shall be subject to the control thereof.”

25 §§ 163, 163a, 196, notes 3 and 4, supra.
Applicability. The trial court determined that § IX was not to1 be applied to the period prior to December 1, 1933; that it should be applied to the period December 1, 1933, to February 16, 1934, and that the effort to recover refunds for the period after February 16, 1934, was premature. The Circuit Court of Appeals thought the section, if valid, generally inapplicable. We are of the opinion that the language of the section was intended to and does make applicable to each Texas consumer the same rates that Arkansas consumers are charged for similar uses and quantity, when the Arkansas rates are lower than the rates granted Texas consumers by the ordinance of the City of Texarkana, Texas, of June 13, 1930. This flows from the words in § IX “place in any rates” less than the Texas ordinance rates. '
The lower rates for Texas are to be effective only when the utility is “finally compelled to, or should voluntarily, place in” effect the lower rates for Arkansas. When a rate is voluntarily placed in effect in Arkansas, the Texas consumers are immediately entitled to the same rate. We construe “finally compelled” as meaning the entry by a court of the final order which makes effective a challenged rate order. No right to demand the lower rate and no cause of action to enforce the right arises until that time. When such order is entered, however, the Texas consumers are entitled to have the lowered rate applied to their consumption for the same period of time
Leave to file a supplemental petition to bring to date the controversy over the refund of rates, collected subsequent to February 16', 1934, should be granted, upon the return of the case to the District Court, on motion of the City of Texarkana, Texas. The present action is an appropriate proceeding for the settlement of the entire rate controversy and the refund of such sums as may be determined, ultimately, to be due the Texas consumers.[27] Where there is a good cause of action stated in the original bill, a supplemental bill setting up facts subsequently occurring which justify other or further relief is proper. If the original decree in the trial court had not been entered, this supplemental petition would simplify the controversy.[28] We think this procedure is equally applicable after remand for further proceedings.[29]
