Petitioner asks that this court by mandate direct respondent, registrar of voters of Los Angeles County, *127 to omit a proposed initiative ordinance from the ballot to be used at the general election to be held November 7, 1950. The principal provisions of the proposed ordinance, in substance and effect, are (1) the repeal of resolutions of the Los Angeles County Board of Supervisors which designate, and pursuant to which the county has acquired, a site for municipal and superior courts buildings; (2) a declaration of the will of the people that such site be used for parking or some other useful purpose; and (3) a designation of another site for a building or buildings to house the courts. It appears also that as a necessary incident of the foregoing provisions, the ordinance would require the withdrawal by the county from, or abandonment of, contracts heretofore made for, or as preliminary to, the construction of the courts buildings on the already acquired site.
Respondent has joined issue by demurrer to the petition, and the proponents 1 of the proposed initiative ordinance have filed a demurrer and answer. Upon the facts pleaded, as admitted by the demurrers and by the answer, we have concluded that the proposed ordinance deals with administrative matters which, under state law, are committed solely to the board of supervisors; therefore, the ordinance is not within the initiative function and the peremptory writ should issue.
By state law 2 boards of supervisors are required to provide “suitable quarters” for superior and municipal courts. Such state law leaves to the boards of supervisors to determine, in *128 each case, what is required to constitute “suitable quarters.” It is undisputed that suitable quarters for such courts are wanting and are needed in Los Angeles County, and that the board of supervisors has so determined. Some three years prior to the filing of the proposed initiative ordinance, the board of supervisors decided upon an area north of Temple Street, bounded on the east by North Broadway, as a site for a municipal courts building and a superior courts building. On June 26, 1947, the Los Angeles city planning commission duly approved the site proposed by the supervisors for the municipal courts building and on August 26, 1948, the commission duly approved the site for the superior courts building. 3 Between October 14, 1947, and July 6, 1948, the board of supervisors adopted a series of resolutions designating and directing acquisition of the area north of Temple Street as a site for the courts buildings. Pursuant to these resolutions, and in performance of the duty enjoined by the state law, the property was acquired at a cost of $1,550,085.61. The board appropriated and allocated funds aggregating $10,699,700 for construction of the buildings on the acquired site; of such funds it has spent $54,517.62 budgeted under the Accumulative Capital Outlay Act (Stats. 1937, ch. 717; Stats. 1949, ch. 14) “for the purpose of constructing” the superior courts building, and $484,883.98 appropriated from general funds “for purposes directly connected with the construction of said courts building. ’ ’ It employed architects who prepared plans for the buildings; it has paid the architects $170,654.40 for their services in respect to the municipal courts building and $507,305.34 for their services in respect to the superior courts building; further fees which it has agreed to pay the architects are payable as construction of the buildings progresses. (The possible liability of the county for further fees or damages in the event that the partially completed project is abandoned is as yet undetermined.) After public hearing the city planning commission duly approved the extent of such buildings and their situation on the area selected as a site. The board of supervisors called for bids for construction of the superior courts building and entered into a contract with the board of the Retirement Association 4 of the county of Los *129 Angeles whereby the latter agreed to erect the municipal courts building and to lease it to the county. (The amount of liability, if any, oh this contract in the event of withdrawal or abandonment by the county is another undetermined matter.)
At this stage in the carrying out of the project, on August 25, 1950, the initiative petition now in question was filed with the respondent. The area, designated by the proposed initiative ordinance as a substitute site for the location of any new courthouse or courts building is south of Temple Street, bounded on the east by North Broadway, immediately across Temple Street from a portion of the site designated and acquired by the board of supervisors.
It is observed that the act of the board of supervisors in determining that “suitable quarters” for the superior and municipal courts were wanting and were needed, and that the provision of such quarters entailed the procurement of a suitable site and the construction of adequate buildings, does not appear to have been challenged by referendum or otherwise, and is not attacked by the proposed initiative ordinance. It is only the designation of the site which has already been acquired, and, perforce incidentally, the making of the architectural and construction contracts which are extant, that are attacked. Under the circumstances of this case, are these matters within the reach of the initiative?
The powers of initiative and referendum in Los Angeles County apply only to acts which are legislative in character, and not to executive or administrative acts. (See
Housing Authority
v.
Superior Court
(1950),
It seems obvious beyond the reach of serious argument that the board of supervisors cannot perform the duty of providing “suitable quarters” for the courts without selecting and designating the sites of the buildings to house the courts, as well as the character and size of the buildings. The determination of what is “suitable” as quarters for the courts necessarily includes the selection of a site as well as ascertainment of the extent and character of accommodations which a building or buildings must contain. Prescribing’ the policy and duty was the legislative act of the state; carrying out the policy by performing the duty is an administrative function delegated by the state to the local governing body, the board of supervisors. “The governing body of the [local political subdivision] ... by its resolution did not make a law but thereby acted in an executive or administrative capacity as an instrumentality of the state to make operative the provisions of a state law already existing.”
(State
v.
Butler
(1945),
Here the state has acted to establish the basic policy and has vested the responsibility for carrying out that policy in a board of supervisors. The steps which the board has taken to carry out the state policy—the determination that for “suitable quarters” it was necessary or expedient to erect new buildings rather than to continue to use existing *131 buildings, the fixing of sites for the buildings to make them convenient for the purpose to be served, the determination of the size of the buildings, the arrangement of space therein to provide courtrooms, jury rooms, judges’ chambers and all the other details which enter into implementing the legislative act of the state—viewed as parts of the entire project, are all inextricably interwoven and related. We are satisfied that, regardless of what might be the character of a particular step in another context, such steps appear here, in the respects in which they are sought to be interrupted and repealed or controlled by the initiative ordinance, to be predominantly and controllingly administrative in character.
The proponents of the initiative measure rely upon the following cases as establishing that the selection of the sites of the courts buildings is a legislative matter:
Hopping
v.
Council of City of Richmond
(1915),
The Hopping
(supra,
As pointed out in
Newsom
v.
Board of Supervisors
(1928),
If the selection of sites of courts buildings were subject to referendum, the electors could nullify every determination of the board of supervisors to erect buildings for the courts and thereby nullify the legislative policy and prevent execution of the duty imposed upon the board of supervisors. Furthermore, a small group, or various small groups, of electors, by repeated initiative proposals for a change of site, could interfere with the supervisors’ attempts to furnish quarters for the courts at any time, even when the period for referendum had passed. Thus, such small group or groups of electors could not merely place the board of supervisors in a strait jacket (see
Housing Authority
v.
Superior Court
(1950),
supra,
It is to be observed also that difficulties resulting from the use of the initiative here proposed are apparent from a consideration of the requirements of the state Planning and Conservation Act (2 Deering’s Gen. Laws, Act 5211c). That act requires that every city and every county adopt a master plan for the development of the area. (§10.) The plan may include, among other things, the locations and arrangement of public buildings. (§44.) The master plan is to be prepared and adopted by the planning commission of the political subdivision. (§ 35.) Before adopting or substantially amending the plan, the commission must hold a public hearing thereon. (§61.) The legislative body of the city or county shall adopt such parts of the master plan “as may practicably be applied to the development of the city or county for a reasonable period of time next ensuing” (§70) and shall “upon recommendation of the planning commission” determine reasonable means for putting it into effect (§71). Before recommending the plan or any amendment to the legislative body, the planning commission shall hold at least two public hearings, and before adopting the plan the legislative body shall hold at least one public hearing. (§72.) The legislative body shall not change the plan without referring the proposed change to the planning commission for a report *135 (§72) and the planning commission must hold public hearings on such proposed changes (§74). The legislative body shall not construct or authorize a public building in an area for which the plan has been adopted without submitting the location and character of such building to the planning commission for a report, and the legislative body can overrule the commission’s disapproval of a proposed public building only by a two-thirds vote. (§73.)
The above prescribed procedure must be followed by the board of supervisors when it is proposed to change the site of a public building. (See
Newsom v. Board of Supervisors
(1928),
supra,
All material contentions advanced by the proponents of the initiative ordinance are necessarily disposed of by our holding that such ordinance deals with matters which are not within the initiative function.
For the reasons above stated, it is ordered that the peremptory writ of mandate issue forthwith directing the respondent to omit the proposed initiative ordinance from the ballot.
Gibson, C. J., Shenk, J., Edmonds, J., Carter, J., Traynor, J., and Spence, J., concurred.
Real Parties’ in Interest petition for a rehearing was denied October 26, 1950. Carter, J., voted for a rehearing.
Notes
The proponents of the initiative ordinance allege that they constitute the “Los Angeles County Courthouse Committee [and that it] is an unincorporated association of twenty-three civic leaders, business men and lawyers of the County of Los Angeles, . . . the majority of whom are citizens . . . and registered voters of said county; said Committee was organized in 1949 for the purpose of obtaining for the County of Los Angeles a single courthouse site . . . for the future construction thereon of a single building or adjacent and connecting buildings, to house the Superior and Municipal Courts and the County Law Library, in lieu of three separate, scattered sites theretofore selected by the Board of Supervisors, for the construction thereon of three separate buildings for said functions.” The committee admits the prior acquisition by the county of the site selected by the board of supervisors and “admits that all of the site selected by the proposed Ordinance is privately owned except for a strip from Broadway to Hill Street with a frontage of about fifty-six (56) feet immediately north of the law library property,” which “law library property,” it is also admitted, “the Board of Law Library Trustees of the County of Los Angeles has held title to” since July 20, 1950, and which was acquired “for the purpose of constructing thereon a separate building for ... [a] County law library” at a cost (for the land) of “about $580,333.”
See post, p. 131.
See discussion of the California Planning and Conservation Act (Deering’s Gen. Laws, Act 5211c), post, p. 70. The city of Los Angeles has a comprehensive zoning plan (Ordinance 90500) and the county of Los Angeles has a master plan (Ordinance 1494).
The county retirement association, which consists of all county employes (Gov. Code, § 31552), is managed by a retirement board of five *129 members (Gov. Code, § 31520). The lease agreement between the Los Angeles retirement board and the county of Los Angeles was entered into under a state law which permits investment of funds of a retirement association in “ [r]eal property or improvements . . . acquired for sale or lease to the county in which the retirement system is established” (Gov. Code, § 31595, par. (e)). Such an investment requires unanimous approval by the retirement board and approval of four-fifths of the board of supervisors. (Gov. Code, § 31601.) It also requires that the property and the plans of the proposed building be examined by an appraiser appointed by the retirement board and board of supervisors; the appraiser must determine whether the investment will return the statutorily permitted rate of interest. (Gov. Code, § 31603.)
