This is an action in declaratory relief by which the plaintiff and respondent, the City of San Diego, seeks to enjoin the defendants and appellants, Otay Municipal Water District and its officers, from operating a water system in and furnishing water to inhabitants of the City of San Diego; and by which three land owners, who intervened in the action, seek a determination dеclaring invalid the proceedings taken by the water district which resulted in the formation of an improvement district that included their property. The court enjoined the construction or operation of any water works by the defendant within the city’s territory without its consent; enjoined the issuance of bonds for the construction or operation of suсh water works without the city’s consent; but did not pass upon the issue raised by the interveners with respect to the validity of the improvement district which contemplated such construction and operation. The interveners also appeal from an order denying their motion for a new trial. The latter appeal should be dismissed as the order in question is not appealable. (Code Civ. Proc., § 963;
Reeves
v.
Reeves,
The plaintiff is a chartered city. The defendant water district was organized under the Municipal Water District Act of 1911. (Stats. 1911, ch. 671, pp. 1290 et seq.) There are approximately 60,000 acres within its boundaries. In 1957, 4,000 of these were annexed to the City of San Diego. In 1959, under proceedings provided by the statute, an improvеment district' was formed within the water district which covered 12,000 of these acres, including the 4,000 theretofore annexed to the City of San Diego, and the issuance of bonds *675 for the construction of a distribution system to furnish water to the land within the improvement district was authorized. At the time in question the territory within the boundaries of the latter district was sparsely populatеd; was not furnished water either by the City or the water district; and the land therein was substantially undeveloped, although a portion thereof was used for dry farming.
Shortly after formation of the improvement district the City brought this action to prevent the water district from furnishing water to the inhabitants of the annexed area and from constructing a water distribution system within that area fоr that purpose, contending that these functions are municipal affairs over which it has exclusive control by virtue of the state Constitution and the provisions of its charter, and that the water district might not engage therein without its consent.
The constitutional sections relied upon provide: (1) that “Any municipal corporation may establish and operate public works for supplying its inhabitants with . . . water. . . .” (Cal. Const., art. XI, § 19) and, (2) that cities organized under charters are empowered “to make and enforce all laws and regulations in respect to municipal affairs, subject only to the restrictions and limitations provided in their several charters. ...” (Cal. Const., art. XI, § 6).
The charter provisions in question are contained in sections 1 and 103.1 of the charter and declare that the city “. . . may own and operate public utility systems, including the joint or sole operation and ownership of utilities for the purchase, development, and supply of water . . . for the use of the City and its inhabitants. . . .” (Stats. 1931, ch. 47, p. 2840, § 1), and that
“No person, firm or corporation shall establish and oрerate works for supplying the inhabitants of The City of San Diego with . . . water . . ., or establish and carry on any business within said City which is designed to or does furnish services of a public utility nature to the inhabitants of said City, without the consent of said City. ...” (Stats. 1953, ch. 106, p. 4005.)
It now is settled that, absent any constitutional or statutory inhibition, the authority conferred by general law upon a public corporation to act within a prescribed area, does not terminate
per se
upon the annexation of a part of that area by a city possessing similar authority; that the issue
*676
presented concerns the intent of the Legislature in the premises; and that the probability of a potential conflict between corporations possessing dual authority, of itself, does not establish an intent against its existence.
(Henshaw
v.
Foster,
*677
The Charter of the City of San Diego, as well as the act under which the defendant water district was organized (Stats. 1911, eh. 671, pp. 1290 et seq.) and the annexation statute by which the overlapping territory in question became a part of the City (Gov. Code, § 35100 et seq.) all are state laws.
(Whitmore
v.
Brown,
In
San Ysidro Irr. Dist.
v.
Superior Court,
“Petitioners [irrigation district] argue that since the district is a public agency created under legislative authority, it cannot properly be said to be exercising a ‘franchise . . . which is of a kind that is within the jurisdiction of such board or body [the legislative body of the city] to grant or withhold. ’ However, the district is exercising a franchise for the distribution of water within the territory which it serves, and that territory is now entirely within the territorial limits of the city. Petitioners admit in their supplemental brief that ‘local legislative bodies may grant franchises for public utilities which are within the jurisdiction of the particular city аnd which are desired as a means of providing services to the inhabitants of that city. ’ While the city cannot create an irrigation district such as petitioner district, the district is exercising a franchise within the territorial limits of such city for the distribution of water, and the franchise so exercised is ‘of a kind that is within [its] jurisdiction ... to grant or withhold. ’ Since the franchise exercised by the district falls within the express terms of section 811, no good reason ap-
*679 pears why the city might not proceed by quo warranto under that section against the district to establish that it now ‘unlawfully holds or exercises’ that franchise.”
The authority of the city referred to in the cited case by which it could grant or withhold the exercise of the irrigation district’s franchise to deliver water within the territorial limits of the former was that contained in section 103.1 of the charter, to which reference heretofore has been made. For the purpose at hand, no valid distinction exists between an irrigation district and a municipal water district. It thus appears that the aforesaid holding by the Supreme Court is determinativе of the issue under consideration and supports the decision of the trial court in the premises.
The foregoing expressed conclusion renders unnecessary a decision upon the complex question whether the power of the water district to furnish water to the inhabitants thereof in furtherance of its general purpose, may not be еxercised within that part of the district annexed to the city because of the constitutional provision, i.e., article XI, section 6, of the California Constitution, declaring that the powers of a charter city with respect to municipal affairs are subject only to the limitations and restrictions contained in its charter. 2
*680
In the case at bar, not оnly did the court determine that the water district may not deliver water to the territory annexed to the city without the latter’s consent, but also determined that the district and its board of directors should not issue bonds for the purpose of ‘1 constructing, operating and installing water facilities” within that portion of the district included in the boundaries of the City of San Diego, unlеss consent for such construction, installation and operation ‘‘is first obtained from plaintiff.” However-, the charter provision in question does not purport to control the authority of the water district to issue bonds for the construction of water facilities. Moreover, there is no indication in the Water District Act that an improvement district within a water district may not include territory annexed to a city. Neither is there any statutory requirement that, under a situation such as is presented by the facts in this case, the consent of the city first must be obtained before proceedings may be undertaken to form an improvement district which includes annexed territory or to issue bonds in connection therewith. Furthermore, as the validity of the bond issue in question might be attacked only in a proceeding maintained by an elector or taxpayer of the district, the city was foreclosed from questioning the same through the instant action.
(Orcutt
v.
Pasadena Land & Water Co.,
The interveners, who arе taxpayers within the district and the owners of two parcels of property within the annexed area, also appeal from the judgment because the court failed to adjudicate the issues presented by their complaint in intervention with respect to the validity of the improvement district, the contemplated issuance of bonds, and thе action of the water district’s board of directors in the premises. They claim that the proceedings taken to form the improvement district did not conform to the requirements of the statute, and also that the provisions thereof respecting its formation deny them due process of law. The complaint in intervention contained three causes of action; the first thereof, in substance, adopted the allegations of the plaintiffs’ complaint ; and the remaining two causes of action contained allegations purportedly sustaining their attack upon the validity *681 of the improvement district. The court made no findings with respect to the latter allegations.
In view of the restricted nature of the proceedings instituted by the city, it is evident that the contentions advanced by the interveners extend the scope of the remedy sought through the original complaint and, under the general rule that an intervener may not broaden the scope of the procedure or remedy offered the original plaintiff, may not be considered in the instant action.
(Wright
v.
Jordan,
Furthermore, the interveners had no authority to bring an action to annul the existence of the improvement district because of a failure to comply with the law under which it purportedly was incоrporated, or because of the unconstitutionality of that law. Such a remedy is not available to a taxpayer as such; may be obtained only through a proceeding in quo warranto instituted by the Attorney General;
*682
and the complaint in intervention, insofar as it sought such relief, did not conform to the requirements of the law in the premises.
(San Ysidro Irr. Dist.
v.
Superior Court, supra,
The judgment is mоdified by striking therefrom that part thereof which enjoins the defendant from issuing bonds, i.e., paragraph 5 of the judgment, and as modified is affirmed. The appeal from the order denying the interveners’ motion for a new trial is dismissed. None of the parties shall recover costs on appeal.
Griffin, P. J., and Shepard, J., concurred.
The petition of defendants and appellants for a hearing by the Supreme Court was denied April 18, 1962.
