Mr. Justice Hays
delivered the opinion of the court.
This is an action brought by Norman E. Berman as a taxpayer and resident of City and County of Denver and as a patron of The Denver Tramway Corporation, a Delaware corporation, on behalf of himself and others similarly situated, against City and County of Denver, a municipal corporation, and The Denver Tramway Corporation, to have ordinance No. 96, series of 1948, declared to be void and of no effect, and the enforcement of same enjoined.
Said ordinance is entitled, and in so far as pertinent, provides as follows:
“A bill for an ordinance concerning the Denver Tramway Corporation; granting to the Denver Tramway Corporation, its successors and assigns, authority for the elimination of rail lines on streets described herein; granting revocable licenses or permits for the operation of buses along and upon certain streets described herein; granting authority to operate trolley coaches or motor buses in lieu of rail lines on streets described herein; adjusting fares and providing for certain operating and regulatory matters.
"Be it Enacted by the Council of the City and County of Denver:
"Whereas, The Denver Tramway Corporation now maintains and operates a transit system composed in part of rail lines and trolley coach lines, operating under and by virtue of Ordinance No. 3 of 1885 and Ordinance [221]*221No. 36 of 1888 and composed in part of lines of gasoline buses operating under revocable permits, over, along and upon certain streets, alleys, viaducts, bridges, public ways and places in the City and County of Denver; and
“Whereas, due to the growth of the City of Denver, the convenience and necessity and the comfort of the inhabitants of the City of Denver require that certain portions of the transit system be changed and modernized to comply with the changed conditions, and to secure the public safety and convenience of the inhabitants of the City of Denver; and
“Whereas, The Denver • Tramway Corporation has heretofore presented to the City Council certain ordinances with respect to the modernization and improvement of its system, and the City and the Company are desirous of completing the modernization of said system at as early a date as possible by converting the remaining rail lines to trolley coach or gasoline bus operation; and,
“Whereas, it is estimated that the program as outlined will require an expenditure of money in excess of six and one-half million dollars ($6,500,000.00), and in order that the company may attract the capital necessary to complete this program and to meet increased expenses, additional revenue in a substantial amount is needed immediately; and,
“Whereas, in order that a more flexible and workable arrangement may be had with respect to future relations between the City and the Company, it is the stated intention and desire of both:
“(1) That additions, extensions and improvements (other than those hereinafter specifically set forth) and various standards of service will be mutually agreed upon from time to time in order to provide adequate and convenient service to the people of Denver;
“(2) That as promptly as possible the City and the Company will co-operate in attempting to agree upon a just, legal and proper valuation of the properties of [222]*222The Denver Tramway Corporation, in order that a just and proper return may be realized through the operations of the Company; and
“(3) That in order to insure a more flexible and workable relationship between the City and the Company, a thorough investigation will be made of the service at cost principle, or some similar plan, in an endeavor to agree upon some such plan to the mutual advantage of the City, the people of Denver, and the Company.
“Now, Therefore, with full regard for and in consideration of the matters and things hereinabove set out, and with the intent and purposes of serving the convenience, necessity and safety of the inhabitants of the City and County of Denver:

“Section 13. In the opinion of the Council, this ordinance is necessary for the immediate protection and preservation of the public health, convenience, safety and general welfare, and it is enacted for that purpose, and shall be in full force and effect immediately after the passage and final publication.”
Defendants’ motions to dismiss the complaint upon [227]*227the ground that the same failed to state a claim against them, or either of them, upon which relief could be granted, were sustained and the judgment of dismissal which followed, is before us for review on writ of error.
The errors upon which plaintiff relies for reversal of the judgment are in substance: That the trial court erred in holding and ruling that the council of City and County of Denver had jurisdiction and authority to pass the above ordinance; and, in particular, in holding that the council had the legislative power to regulate the charges for service by public utility corporations operating within City and County of Denver.
We shall hereafter refer to plaintiff in error as plaintiff; City and County of Denver as City; The Denver Tramway Corporation as Tramway; and the city council of City and County of Denver as council.
It is contended by plaintiff that the people of City and County of Denver have exclusive power to grant franchises to public utility corporations and to regulate the charges for service, and that no such power is vested in the muncipality known as City and County of Denver or in its legislative department, its council. On the other hand, defendants Tramway and City contend that the council had full power and authority to pass said ordinance and to regulate such rates.
Prior to December 1, 1902, the date when Article XX of the Constitution, pursuant to which City and County of Denver exists, became effective upon the proclamation of the then governor, power to license and regulate utility corporations and their rates was vested by the state legislative charters in the council of said city. S. L. ’66, p. 95; S. L. ’74, p. 264; S. L. ’83, p. 60; S. L. ’85, p. 82; S. L. ’89, p. 127; and S. L. ’93, p. 131.
Section 4 of article XX of the Constitution, provides inter alia:
“The people of the City and County of Denver are hereby vested with and they shall always have the [228]*228exclusive power in the making, altering, revising or amending of their charter * * *.
“No franchise relating to any street, alley hr public place of the said city and county shall be granted except upon the vote of the qualified taxpaying electors, and the question of its being granted shall be submitted to such vote upon deposit with the treasurer of the expense (to be determined by said treasurer) of such submission by the applicant for said franchise. * * *”
Section 5 provides, inter alia: “The citizens of the City and County of Denver shall have the exclusive power to amend their charter or to adopt a new charter, or to adopt any measure as herein provided * * (Emphasis supplied)
Section 6 of said article, as amended November 5, 1912, provides in part: “The people of each city or town of this state, having a population of two: thousand inhabitants as determined by the last preceding census taken under the authority of the United States, the State of Colorado, or said city or town, are hereby vested with, and they shall always have, power to make, amend, add to or replace the charter of said city or town, which shall be its organic law and extend to all of its local and municipal matters.”
After article XX was adopted by the people of the State of Colorado in 1902, and prior to the adoption of the first people’s charter in 1904, the council, in October, 1903, passed ordinance No. 87, granting to Colorado Eastern Railroad Company the right to occupy certain streets and alleys in City and County of Denver, either as a grant or as a mere permit or license. The validity of said ordinance was questioned in Ward v. Colorado Eastern Railroad Co., 22 Colo. App. 332, 125 Pac. 567, wherein the Court of Appeals determined that after the effective date of said article XX, the power to regulate utilities and their rates was transferred from the city council to the qualified taxpaying electors of the new [229]*229municipality; that the pertinent provisions of article XX were self-executing; that the adoption of a charter was not required to give effect thereto; and in connection therewith said:
“The prime purpose of the constitutional amendment was to bestow upon the inhabitants of the city of Denver, and certain surrounding territory, a very greatly increased measure of home rule, and the object of the provision now under consideration was to give the taxpaying electors of the aforesaid territory absolute control over the granting of franchises. It must be clear that the legislature in framing and submitting the amendment, and the people in adopting it, had these purposes in mind. Therefore, it cannot be assumed that either the legislature or the people deliberately incorporated in or omitted from the amendment provisions calculated to work powerfully against and greatly delay the adoption of the charter for which the amendment provided, and which was one of its important purposes.
“ ‘We reach the conclusion, without hesitancy or misgiving, that immediately upon the taking effect of art. XX, the power to grant franchises like the one in question was thereby transferred from the city council to the qualified tax-paying electors of the new municipality. Hence it follows that the ordinance of 1903 was null and void, and ‘upon authority we hold that the ordinance in the case at bar was void, and conferred no authority whatever upon the defendant, and cannot be invoked to give it protection.’ D. & S. Ry. Co. v. Denver City Ry. Co., 2 Colo. 683.’”
The opinion in the above case was affirmed by us in Colorado Eastern R.R. Co. v. Ward, 59 Colo. 589, 151 Pac. 1196.
In a later case, in dealing with the same subject matter, we said: “* * * The purpose of the article was to enlarge the powers beyond those usually granted by the Legislature, and to bestow upon the people of the munic[230]*230ipaility ‘every power possessed by the Legislature in the making of a charter for Denver.’ Denver v. Hallett, 34 Colo. 393, 397, 83 Pac. 1066. And, subsequently, in Londoner v. Denver, 52 Colo. 15, 22, 23, 119 Pac. 156, referring to the Denver-Hallett case, we further declared: ‘By that decision we determined that the powers enumerated in section 1 of article XX of the Constitution do not constitute a limitation of the powers conferred upon the municipality; and, moreover, the article conferred upon such people (of the City and County of Denver) every power possessed by the Legislature in making a charter for Denver.’” City and County of Denver v. Mountain States Telephone & Telegraph Co., 67 Colo. 225, 184 Pac. 604. (Emphasis supplied)
Pursuant to the authority vested in the people of City and County of Denver by said article XX, as hereinabove shown, there was adopted March 29, 1904, at a special city election called for such purpose, the first people’s charter, which included section 268 (section 280 of the 1927 Compilation), which provides: “All power to regulate the charges for service by public utility corporations, is hereby reserved to the people, to be exercised by them in the manner herein provided for initiating an ordinance.” (Emphasis supplied) Denver Municipal Code, 1927, p. 141, §280.
The construction to be given this section gives rise to the principal point in controversy herein. It is contended by plaintiff that under a proper interpretation of the section, the exclusive power to regulate rates in Denver is vested in the people "of the City and County of Denver, while defendants contend that the City through its council has concurrent power with the people in respect to such regulation.
In support of defendants’ contention it is argued with much vigor that the words “all power,” as used in said section 280, does not mean “all power” but “is a very elastic word having many meanings,” and “doubtlessly means ‘full’ or ‘complete’ power” and “was doubtlessly [231]*231inserted in section 280 as a warning to public utilities seeking franchises. It says to such public utilities that in the last analysis, the people retain the right to fix rates.”
The above quotations were taken from the brief of the city attorney, but such argument has been approved and emphasized by counsel for Tramway in their brief. We are not prepared to place such a strained and unusual construction upon the word “all” as that given to it by defendants. We find that the word “all” appears approximately 400 times in the charter and approximately 33 times in article XX, and in each instance (except where its meaning is specially qualified as in section 209), in so far as we are able to determine, the word was given a very comprehensive meaning, was used in its popular and ordinary sense, and included everything and excluded nothing. The contention of counsel for defendants to the effect that the word “all” as used in section 280 does not mean “all,” but merely a part, of the power to regulate charges for service by public utility corporations, is manifestly weakened by the fact that they also contend that the word “all” as used in section 18 of the Speer Amendment hereinafter set forth (section 209 of the 1927 charter), means “all” even though the phrase “all legislative powers” is limited therein by the word “possessed,” and by the phrase “except as otherwise provided by this amendment.”
We think there is no escape from the conclusion reached by the late Mr. Justice Denison in his concurring opinion in City and County of Denver v. Mountain States Telephone & Telegraph Co., supra, when he said: “I cannot agree with the proposition that the power to regulate rates is not expressly granted by such language. An express grant of all power is an express grant of every power, and the ratification of Charter Sec. 280 is an express grant.” (Emphasis supplied)
The above conclusion that “all power” means “exclusive power” and “every power,” is fortified by the [232]*232further fact that in the 1904 charter, provision was made in chapter IX thereof, for the city itself -to acquire, maintain, improve, and operate public utilities. Section 293 (formerly 263) expressly authorized the council “to fix the rates for service to be rendered in each public utility, work or way * * *.” The failure of the charter convention to use any similar language in section 280 with respect to privately owned utilities operating under franchises seems conclusive that it was not the intention of the charter framers to grant the council any power relative to regulating charges for service by private utility companies.
It next is contended that if section 280 is construed as above, then and in that event “the Speer amendment repealed section 280 as an exclusive grant of power, and after the passage of the amendment in 1916, the power became concurrent.” This contention presents the question as to whether or not there is an irreconcilable conflict between section 18 of the Speer Amendment (section 209 of the 1927 Compilation), and section 280, which was adopted as a part of the original charter in 1904. Section 18 of the Speer Amendment was originally section 4 of the 1904 charter, and provided inter alia: “All legislative powers conferred by the constitution upon the city and county except as otherwise provided, shall be vested exclusively in a council, consisting of a board of supervisors and a board of aldermen. * * *”
Later-, a commission form of government was adopted and the above section amended February 14, 1913, to read: “All legislative powers possessed by the City and County, except as otherwise provided, shall be vested in a council of five commissioners, hereinafter designated as commissioner of property, commissioner of finance, commissioner of safety, commissioner of improvements, and commissioner of social welfare. * * *” (Emphasis supplied)
Said section 4 was again amended May 17, 1916, by [233]*233the so-called Speer Amendment, which created the mayor form of government, and was designated therein, as above indicated, as section 18 thereof, now section 209, and as amended, reads in part: “All legislative powers possessed by the City and County of Denver, conferred by article XX of the Constitution of the state of Colorado, or contained in the charter of the City and County of Denver, and otherwise existing by operation of law, except «s otherwise provided by this amendment, shall be vested in a board of councilmen to consist of nine members.” (Emphasis supplied)
It will be observed that in both the 1913 and 1916 amendments the word “possessed” follows the phrase “all legislative powers” thereby plainly indicating that some legislative powers were not “possessed” by the council. This interpretation of section 209 is in harmony with our construction of section 280 to the effect that the legislative power to regulate rates of utility corporations in Denver is one of those powers which the council does not possess. So construed, no repugnancy exists between the sections, both are given effect, and consequently, no part of section 280 is repealed by implication or otherwise.
The next argument advanced by the Tramway is that: “Moreover, under section 281 of the charter, the right to grant temporary permits is expressly recognized. It is submitted, that for that section to be effective by necessary implication temporary rights in relation to temporary permits must be authorized. The city so argues in its brief and we concur, and we think this court must also come to the same conclusion.”
Section 281 to which the above contention relates, provides: “The council may grant a license or permit at any time, in or to any street, alley or public place, provided, such license or permit shall be revocable at any time, and such right to revoke shall be expressly reserved in every license or permit which may be granted hereunder.”
[234]*234A similar contention to that above set forth was made in Ward v. Colorado Eastern R.R. Co., supra, and the, Court of Appeals, contrary to such contention, held: “It is contended on behalf of defendant that the ordinance of 1903, even if void as a franchise, nevertheless constitutes a valid permit or license which remained good as against plaintiff, and as against the city, until the same was revoked by the authority that attempted to make the grant, namely, the city. Under the law existing prior to the adoption of art. XX, this contention may have been sound, that is, the council, having under the previous law, authority to make the grant, a defective attempt by it to grant a franchise might operate as a license or permit. But the law with reference to grants of this character was so radically and fundamentally altered by the constitutional amendment as to make prior decisions on this point inapplicable. The council, being wholly without authority to grant a franchise in 1903, its abortive attempt so to do conferred no right whatever upon the defendant company. D. & S. Ry. Co. v. Denver City Ry. Co., supra. Especially is this true where the attempted grant was designed to confer a right on the company to construct the main line of its road over the streets of the city, the council being without power to make grants of this character, we are not called upon, under the facts disclosed by the record in this case, to consider and determine its power and authority to grant permits for local or limited incidental privileges such as that involved in the case of McPhee & McGinnity v. U. P. Ry. Co., 158 Fed. 6, to which our attention has been directed.”
Section 281, above mentioned, was before us for interpretation and construction in Baker v. Denver Tramway Co., 72 Colo. 233, 210 Pac. 845, which concerned the validity of ordinance No. 74, series of 1921, purporting to authorize the Tramway to operate its street cars upon Downing Street, a street not mentioned in its franchise of May 15, 1906. Notwithstanding the fact that the [235]*235franchise under which it was then operating was adopted pursuant to the initiative provisions of the charter and voted upon by the people of the City and County of Denver, the Tramway insisted, as here, that the city council had authority, under the provisions of section 281 of the charter, to enlarge and extend its franchise privilege by the issuance of a temporary permit and revocable license for the operation of said street cars, upon the above named street. In rejecting such argument, we said:
“The right given by this ordinance was to lay a track in a street as a part of the main line, a right which is in'no sense incident to the original franchise. If it be a franchise, it cannot be taken out of the constitutional inhibition by calling it a license. That the right to use the streets of the city for street railroads is a franchise is a matter not open to dispute. If, by a permit of this kind,' the city council can grant the right to run cars on a street as a part of the main line, it can in effect enlarge the franchise, and wholly defeat the purpose of the people who placed the restrictions as to franchises in the Constitution.
# ❖ ❖
“We are of the opinion that the city council had no authority to grant to the defendant company the rights which the ordinance purports to give. To uphold such an ordinance is to approve a palpable attempt to evade a provision of article XX of the state Constitution, which reads as follows:
“ ‘No franchise relating to any street, alley or public place of the said city and county shall be granted except upon the vote of the qualified taxpaying electors.’
“If the charter provision for revocable permits authorizes the council to grant permits, which are in effect franchises, such provisions are invalid as in contravention of the Constitution. Just what such permits may cover, we are not now called upon to determine.”
It next is contended by the Tramway, in which [236]*236the City joins, that: “Practical interpretation by the city in the past, of which the court may take judicial notice, eliminates any legal question of the power of the council to regulate fares and charges.”
It is urged under the above heading that: “In many instances in the past twenty-five years the city council has regulated the charges' by public utilities by ordinance without any initiated action by taxpaying electors. The present rates of the Telephone Company were fixed by the Council without initiated action by ordinance No. 140, passed in September, 1947. The 1930 ordinance fixing the fares for the Tramway, expressly repealed by the ordinance here questioned, was passed by ihe city council without initiated action.”
Attention also is called to the passage by the city council of certain taxicab ordinances without initiated action.
From the above circumstances, said to exist, but not found in the record, defendant Tramway, reaches the following conclusion, in which the City concurs: “The fact that many years ago some ordinances were adopted after initiated action, and that in the last twenty years all such ordinances have been adopted without initiated action, merely indicates that the city authorities have interpreted the charter provisions as permitting the enactment of such ordinances both by the council and through the initiative.”
The obvious and conclusive answer to the above argument is that the people of City and County of Denver, in whom is vested the exclusive power to grant, franchises and regulate rates, are not bound by abortive attempts of the council to do so. “ ‘Contemporary construction can never abrogate the text; it can never fritter away its obvious sense; it can never narrow down its true limitations; it can never enlarge its natural boundaries.’ Story on Const., sec. 7.” People ex rel. Seeley v. May, 9 Colo. 80, 10 Pac. 641; People ex rel. v. Prevost, 55 Colo. 199, 209, 134 Pac. 129; Koenig, [237]*237County Treasurer v. Jewish Consumptives’ Relief Society, 98 Colo. 253, 255, 55 P. (2d) 325; People ex rel. v. Hinderlider, 98 Colo. 505, 507, 57 P. (2d) 894; Montgomery v. City and County of Denver, 102 Colo. 427, 436, 80 P. (2d) 434.
A further answer to such contention is that section 6 of article XX of the Constitution was amended November 5, 1912, and as amended it was declared, inter alia:
“It is the intention of this article to grant and confirm to the people of all municipalities coming within its provisions the full right of self-government in both local and municipal matters and the enumeration herein of certain powers shall not be construed to deny such cities and towns, and to the people thereof, any right or power essential or proper to the full exercise of such right.
“All provisions of the charters of the City and County of Denver * * * as heretofore certified to and filed with the Secretary of State * * * which provisions are not in conflict with this article, * * * are hereby ratified, affirmed and validated as of their date.” S. L. ’13, p. 671. (Italics supplied)
One of the provisions of the original charter which was by the above amendment “ratified, affirmed and validated” was section 280, which reserved the exclusive power to regulate utility rates in the people of the City and County of Denver. Thereafter the general assembly adopted an act known as “Public Utilities Law,” S. L. ’13, p. 464, which provided among other things: “Section 14. The power and authority is hereby vested in The Public Utilities Commission of the State of Colorado, and it is hereby made its duty to adopt all necessary rates, charges, and regulations to govern and regulate all rates, charges and tariffs of every public utility of this State as herein defined. * * *”
After the passage of said public utilities law controversy arose as to what agency had jurisdiction to [238]*238regulate utility rates in the City and County of Denver. It was contended on behalf of the Public Utilities Commission and the Mountain States Telephone and Telegraph Company that the commission had such jurisdiction, and City and County of Denver, for itself and on behalf of its citizens, contended that the people of City and County of Denver alone had such power. The controversy reached this court, and the question was decided January 14, 1919, in City and County of Denver v. Mountain States Telephone & Telegraph Co., supra, adverse to the contentions here made by defendants.
It was there held in substance: That by article XX every power theretofore possessed by the state legislature in the making of a charter for Denver was bestowed upon the people of the municipality; that said article created a new agency for regulating utilities operating within the city; that the power to regulate must be exercised “only to the extent and in the manner ■and form prescribed”; that the people of City and County of Denver were vested with exclusive power to make, alter, revise, or amend the charter, and in the exercise of which power adopted section 280 of the charter; that their right to do so was ratified, affirmed and validated by the adoption of the home rule amendment in 1912; and that section 280 of the charter “was in substantial'effect written into the constitution.”
The following excerpts from the opinion in the above case, are especially pertinent to the present inquiry.
“The granting of the right by the city to a public service corporation to use the streets of the municipality or the granting by the General Assembly to such a corporation the right to use the highways of the state, is the exertion of the proprietary power of the sovereign. The regulation, however, of the business of such public service corporation, whether performed by the Legislature or the municipality, is an exertion of the governmental power of the sovereign. Indeed, the governmental regulation of a business, whatever its character, [239]*239is always the exertion of the police power, and, therefore, law making. In the exercise of this power no agent can exhaust it and no vested right may be acquired therein. Such governmental power is inherent in the sovereign and may be exerted, withdrawn and re-exerted according to the 'judgment, whim or caprice of the sovereign. The ever-existing, inherent and inalienable power resides in the sovereign, to wit, the whole people of Colorado, to regulate the business of every public utility operating within the limitations of the state and to make and to remake, as changed conditions may require, a maximum schedule of rates to be charged for the service rendered by such utility.”

“However, were the law otherwise, the Constitution has expressly authorized the people of the municipality to regulate the charges for service by public utilities operating therein. Prior to the adoption in 1912 of the amendment to article XX of the Constitution, the City and County of Denver had attempted, at least, to exercise the power of regulating public utilities. Section 280, supra, of its charter had been enacted and such charter with that section therein was on file in the office of the Secretary of State. The constitutional amendment expressly approved, ‘ratified, affirmed and validated’ such charter and each and every provision thereof ‘not in conflict with’ Article XX. It further declared that such charter and the ordinances made pursuant thereto in local and municipal matters shall supersede within the territorial limits of the municipality, any law of the state in conflict therewith. This provision of the charter meaning section 280 was in substantial effect written into the Constitution.” (Emphasis supplied)
The case, Denver v. Telephone, etc. Co., supra, was taken to the Supreme Court of the United States on writ of error and dismissed by that court in Mountain States Telephone and Telegraph Co. v. Denver, 251 U. S. 545, 40 Sup. Ct. 219, 64 L. Ed., 407. Such disposition [240]*240was in harmony with the decision of that court in Home Telephone Co. v. Los Angeles, 211 U. S. 265, 29 Sup. Ct. 50, 53 L. Ed., 176, upon which our decision in the telephone case was largely based.
The contention that any agency other than the people of the City and County of Denver, through the initiative, has authority to regulate rates or grant franchises in Denver, has never been legally supportable since the rendition 'of the opinion in the telephone case, supra, and this is not changed by the contemporaneous construction which the council may have from time to time placed upon the applicable provisions of the charter.
Section 280 of the charter not only reserves to the people of Denver the power to regulate rates, but prescribes the exact method by which such regulation shall be accomplished, to wit: “In the manner herein provided for initiating an ordinance.” The section to which the above relates is section 273, which provides in part: “Section 22. Any proposed ordinance may.be submitted to the council by petition therefor of qualified electors equal in number to at least five per cent, of ]fche last preceding vote for mayor, and such proposed ordinance shall be passed without alteration by the council, * * * or the council shall refer such proposed ordinance to the qualified electors at the next municipal election held not less than sixty days after such petition is filed * * * »
The above method of exercising the legislative power to regulate charges of utility companies is exclusive; any attempt to regulate same by any other method is ultra vires, and void; “ '* * * that where the mode in which their power on any given subject can be exercised is prescribed by their charter, the mode must be followed. The mode in such cases constitutes the measure of power.’ ” Keese v. City of Denver, 10 Colo. 112, 122, 15 Pac. 825; Durango v. Pennington, 8 Colo. 257, 7 Pac. 14; Sullivan v. City of Leadville, 11 Colo. 483, 18 Pac. 736; Cordilla v. Pueblo, 34 Colo. 293, 294, 82 Pac. 594; Weaver [241]*241v. Canon Sewer Co., 18 Colo. App. 242, 245, 70 Pac. 953; Sauer v. Town of Gillett, et al., 20 Colo. App. 365, 78 Pac. 1068; State ex rel. v. Burr, 79 Fla. 290, 84 So. 61; City of Ft. Scott v. Eads etc. Co., 117 Fed. 51, 54, 54 C. C. A. 437.
The prescribed method “must be followed as it excludes all others by implication of law and a material departure therefrom is not a colorable compliance.” Willman v. Corsicana (Tex. Civ. App.), 213 S.W. (2d) 155.
The aims, objects and purposes of the long and involved ordinance here considered, as stated by counsel for the Tramway in their brief and not denied by the City, is:
“That the passage of the ordinance was advisable to enable the City and the Tramway to agree with respect to future relations, and particularly ■ upon the nature of the improvements to be made from time to time; upon the just, legal and proper valuation of the Tramway’s properties in order that a just and proper return may be realized by it on its operations; and upon a more flexible working arrangement between the City and the Tramway in a mutual endeavor to agree upon some plan of rate fixing which would operate to the advantage of the city, the people and the Tramway.
“Upon these findings of the council, the provisions of the ordinance relating to the change in fare were adopted. Certain routes and reroutes of operation by trolley coaches and trackless trolleys in lieu of operations by rail were determined upon; a license was granted for the operation and rerouting of motor busses over other lines; and all of these were agreed to constitute the modernization program * * (Emphasis supplied)
The ordinance here considered makes provision for the Tramway to file its written acceptance of all contractual provisions in the ordinance within ten days •from the date thereof. It is assumed that such was done [242]*242within the time and manner specified. It is not indicated what parts are, and what parts are not, considered contractual in their nature so as to require an acceptance thereof to make them binding.
With respect to the granting of franchises, the regulation of rates, and the extension and enlargement of franchise privileges under the authorities above cited, such enumerated powers can only be exercised through the initiative upon a vote of the qualified taxpaying electors as by charter provided, and cannot be made the subject of a contract between the City and Tramway. Such attempts “to agree upon some plan of rate fixing” cannot be permitted to supercede, abrogate, or cast aside mandatory provisions of the organic law of the City.
Nothing appearing in the record or the briefs to justify a departure from our former decisions, we conclude that the adopted ordinance here considered constitutes an attempt to grant, extend and enlarge franchise privileges and to regulate charges for service by the Tramway, a public utility corporation, operating within City and County of Denver, contrary to, and in violation of, article XX of the Constitution as amended, and the charter adopted pursuant thereto, and that the same is void and of no effect.
We find no merit in other questions advanced. The judgment of the trial court is reversed. Further proceedings, if any, shall be in harmony with the views herein expressed.
