No brief was filed for appellees in No. 190. Mr. Chief Justice White delivered the opinion of the court: At the time these suits were begun the appellants were engaged in supplying electricity or gas to the municipal corporations who are the appellees. This service was being rendered by virtue of ordinances conferring franchises to use the city streets during twenty-five years in two of the cases, and twenty years in the other. The ordinances contained a schedule of maximum rates. After they were in effect a few years the three suits which are before us were begun against the cities, with the object of preventing the enforcement [541] of the maximum rates specified in the ordinances, on the ground that such rates were so unreasonably low that their continued enforcement would deprive the corporations of remuneration for the services by them being performed, and in fact, if enforced, would result in the confiscation of their property, in violation of the due process clause of the 14th Amendment to the Constitution of the United States. In the three cases the court granted a temporary injune-, (N.S.) 1151, 33 Sup. Ct. Rep. 729, Ann. tion restraining the enforcement of the Cas. 1916A, 18; Cedar Rapids Gaslight maximum rates, and allowed an order Co. v. Cedar Rapids, 223 U. S. 655, 56 permitting, pending the suits, a higher charge. The cases were submitted upon the pleadings, and without the taking of testimony upon issues which presented the contention that the ordinances were contracts, and therefore the maximum rates which they fixed were susceptible of continued enforcement against the corporations, although their operation would be confiscatory. In one opinion, applicable to the three cases, the court stated its reasons for maintaining this view, but directed attention to the fact that no proof had been offered concerning the confiscatory character of the rates, and pointing out that, as such subject might become important on appeal, it would be necessary to restore the cases to the docket for proof in that regard unless the situation was remedied by agreement between the parties. Thereupon the pleadings were amended so as to directly present, separately from the other issues in the case, the right of the cities to enforce the ordinance rates in consequence of the contracts, without reference to whether such rates were, in and of themselves, confiscatory. Upon its opinion as to the existence of contracts and the power | to make them, as previously stated, the court entered decrees enforcing the ordinance rates which are now before us for review because of the constitutional question involved.

S. 178, 194, 62 L. ed. 649, 662, P.U.R.1918C, 640, 38 Sup. Ct. Rep. 2178); and (b) that where, however, the public service corporations and the governmental agencies dealing with them have power to contract as to rates, and exert that power by fixing by contract rates to govern during a particular time, the enforcement of such rates is controlled by the obligation resulting from the contract, and therefore the question of whether such rates are confiscatory becomes immaterial (Freeport Water Co. v. Freeport, 180 U. S. 587, 593, 45 L. ed. €79, 686, 21 Sup. Ct. Rep. 493; Detroit v. Detroit City R. Co. 184 U. S. 368, 46 L. ed. 592, 22 Sup. Ct. Rep. 410; Knoxville Water Co. v. Knoxville, 189 U.

S. 399, 63 L. ed. 669, 6 A.L.R. 1648, P.U.R.1919D, 239, 39 Sup. Ct. Rep. 349). It follows that, as the rates here involved are conceded to be confiscatory, they cannot be enforced unless they are secured by a contract obligation. The existence of a binding contract as to the rates upon which the lower court based its conclusion is, therefore, the single issue upon which the controversy depends. Its solution turns, first, upon the question of the power of the parties to contract on the subject, and second, if they had such power, whether they exercised it. Two propositions are indisputable: (a) That although the governmental agencies having authority to deal with [542] the subject may fix and enforce reasonable rates to be paid public utility corporations for the services by them rendered, that power does not include the right to fix rates which are so low as to be confiscatory of the property of such corporations (Reagan v.

That was a [543] As to the first, assuming, for the sake of the argument only, that the public service corporations had the contractual power, the issue is, Had the municipal corporations, under the law of Iowa, such authority? Its possession must have been conferred, if at all, by § 725 of the Iowa Code of 1897, which deals with that subject. That statute came before the supreme court of Iowa for consideration in the very recent case of Woodward v. Iowa R. & Light Co. "It will be noted from the foregoing that the legislative power to fix rates is conferred by this section upon the city council. The legislative power thus conferred is a continuing one, and may not be abridged or bartered away by contract or otherwise. There was suit by the town of Woodward to com-, poses,1 [and to regulate and fix the rent conferred upon the city council in all "The defendant's franchise in the town of Woodward was granted in June, 1912, by ordinance duly enacted by the city council and duly approved by vote of the electors, as required by 8 720 of the Code. Section 6 of the ordinance which granted the franchise specified the rates to be charged by the defendant to consumers. The term of the franchise was twenty-five years.
