*840 Opinion
The Director of the Department of Food and Agriculture of the State of California (the Director) appeals from an order awarding attorney’s fees pursuant to Code of Civil Procedure section 1021.5 1 to respondents as the successful parties in litigation which challenged the validity of mandatory minimum retail milk prices in the state. Respondents are the Consumers Cooperative of Berkeley, a California corporation, and the Consumers Union of the United States, a nonprofit membership organization.
I
In the late 1930’s the Legislature enacted the Milk Stabilization Act, which authorized the Director to set minimum prices for milk at the producer, wholesale, and retail levels. (See
Jersey Maid Milk Products Co.
v.
Brock
(1939)
Over a period of years, changes in milk production, marketing, and distribution undercut the original justifications for mandatory minimum wholesale prices, and in 1973 and 1974 minimum wholesale prices were suspended throughout most of the state.
In the early 1970’s, various consumer groups and others began urging unsuccessfully that there was also no longer any need for mandatory minimum retail milk prices. During 1974 and 1975, respondent Consumers Cooperative of Berkeley, Inc. (Cooperative), a consumer-owned retail food chain, respondent Consumers Union (Union) and other consumer groups submitted several petitions requesting the Director to suspend the retail milk price regulations.
There was little response to these petitions. In April 1975, the Director did suspend minimum retail prices only in the Sacramento area; however, *841 despite requests by various groups, the department made no public comment regarding the effect of the experiment, and refused requests by these consumer groups to release a draft of a report documenting the positive impact and lack of adverse consequences of the suspension.
Early in 1976, Cooperative decided to challenge the legality of the minimum milk retail price regulations through litigation. On February 13, 1976, it began to sell milk at eight cents per half gallon below the minimum price then set for its marketing area. On February 15, the Director obtained a temporary restraining order prohibiting Cooperative from selling milk at prices below the mínimums. On March 10, a preliminary injunction was issued; however, the court limited the effectiveness of the injunction to 120 days and stated that Cooperative had “made a colorable showing that it will prevail at a trial on the merits . . . .”
Cooperative and Union then filed a cross-complaint and a cross-complaint in intervention seeking an injunction against the continued enforcement of minimum retail milk price orders, and a declaration that the statewide minimum retail milk pricing program was unconstitutional. The Director demurred to both cross-complaints on various grounds; the demurrer was overruled except with respect to one cause of action.
The Director also filed a complaint pursuant to former Food and Agriculture Code section 62642 against Cooperative, seeking civil penalties of $19,000.
Respondents commenced discovery. During a deposition in July 1976, the Director stated that he had never considered that the suspension of retail milk prices in the state was warranted. He also testified that while suspension of milk prices on a statewide basis was an “ongoing viable alternative in an analytical sense,” he was not giving the matter specific consideration at that time.
In August 1976, however, L. R. Walker, chief of the department’s Bureau of Milk Stabilization and Bureau of Milk Marketing Enforcement testified during a deposition that the department was considering holding hearings on retail price suspension.
The parties then entered into settlement negotiations. Two weeks before the September 1976 trial date, the parties agreed to a memorandum of understanding as follows. The trial date would be continued to November 15, 1976. If the Director failed to notice formal public hearings on the statewide suspension of minimum retail milk prices by that date, the action would be *842 tried. If the Director conducted hearings and suspended minimum prices by January 1, 1977, respondents would drop their challenges to the statutory and administrative procedures as moot. In addition, pursuant to a separate agreement, the Director’s “companion action” for civil penalties was to be dismissed, with Cooperative remitting a payment of $500 to the Director.
In November, the Director issued notice of hearings. During November and December, respondents, among others, appeared at various administrative hearings, presenting testimony in favor of suspension. On December 30, 1976, the Director issued orders suspending minimum retail milk price regulations throughout the state.
On March 14, 1977, respondents moved for an award of attorney’s fees on the ground that they were the prevailing parties in this litigation. The trial court concluded, inter alia, that the action “set in motion the machinery by which milk prices ultimately were suspended,” and that respondents were entitled to fees. 2 After an additional hearing, the court awarded fees in an amount in excess of $200,000. The award included compensation for services rendered in the civil penalty action and at the suspension hearings.
II
First, the Director contends that the trial court erred in overruling its demurrers to the cross-complaint and cross-complaint in intervention. The Director reasons that the overruling of the demurrers was “erroneous and prejudicial since it allowed the lower court to retain jurisdiction in the matter and ultimately make the award of attorney’s fees.”
To overcome respondents’ argument that the rulings on the demurrer are not cognizable in this appeal, the Director relies in part on the rule that although an order overruling a demurrer is nonappealable, it is reviewable on appeal from the final judgment entered in the action. (See, e.g.,
Miller
v.
Pacific Constructors, Inc.
(1945)
Relying on
Nadeau
v.
Helgemoe
(1st Cir. 1978)
In
Folsom
v.
Butte County Assn. of Governments, supra,
It should be noted, however, that the cases which the Supreme Court cites,
Bonnes
v.
Long
(4th Cir. 1979)
We need not decide in this case whether our Supreme Court has impliedly rejected the applicability of the second prong of the Nadeau test in this state. Even if that test were applicable, it would not require this court to analyze each of appellant’s contentions with respect to the overruling of the demurrers. The trial court unquestionably concluded that respondents’ claims were not frivolous or groundless when it granted only a limited preliminary injunction, expressly noting that respondents had made a colorable showing that they would prevail at a trial on the merits of the case. 4 We are also satisfied that the litigation was not frivolous or groundless.
Ill
Next, the Director contends the trial court erred when it concluded that there was a causal connection between this action and the suspension of retail milk prices.
In order to justify a fee award, there must be a causal connection between the lawsuit and the relief obtained.
(Westside Community for Independent Living, Inc.
v.
Obledo, supra,
In general, whether plaintiffs have met the statutory requirements for an award of fees pursuant to section 1021.5 is a matter for the discretion of the trial court. (See
Press
v.
Lucky Stores, Inc.
(1983)
Appellant first attacks the court’s causation determination on the ground that the only evidence upon which the court relied was the statements in the declarations of L. R. Walker and Lawrence Shepard that they believed the litigation was the catalyst in bringing about the suspension of prices; appellant contends that those statements were inadmissible, either as hearsay or for lack of personal knowledge of the declarant.
It is true that an affidavit made on information and belief is hearsay and not proof of the facts stated therein.
(Jeffers
v.
Screen Extras Guild, Inc.
(1955)
Appellant also argues that the trial court’s causation determination is contrary to “emerging legal policies” which dictate that courts should be cautious in awarding fees when the action at issue has led to a quasi-legislative change. Despite appellant’s policy arguments, it is settled that fees may be awarded when there is a causal connection between a plaintiff’s action and the result sought, even if that result comes about through legislative action. (See, e.g.,
Folsom
v.
Butte County Assn. of Governments, supra,
32 Cal.3d at pp. 686-687;
State of California
v.
County of Santa Clara
(1983)
Finally, appellant suggests that the court’s causation determination creates a conflict with the requirement that the Director’s suspension decision must satisfy certain procedural and evidentiary requirements, and with the presumption that the Director met these requirements in making his decision. However, appellant’s characterization of the trial court’s determination is inaccurate. The trial court expressly rejected any contention that the ultimate decision to suspend was caused by threat of suit; rather it determined that the litigation set in motion the process which eventually resulted in the suspension.
IV
Next, appellant contends that the trial court abused its discretion in determining the amount of the fees awarded. Appellant’s primary objection is to the award of fees for services performed in conjunction with the administrative proceedings, on the ground that California law precludes a fee award in such proceedings. In addition, appellant objects to the award for services rendered in the civil penalty action, on the ground that it was a separate' action in which respondents were unsuccessful. Finally, appellant objects to compensating Attorney Martilla at $60 per hour without distinguishing between time spent before and after her admission to the bar.
A. Fees for Services at Administrative Hearings
As has already been discussed, among the requirements of section 1021.5 is that the party to whom fees are awarded must be “successful.” (5) It is settled, however, that a party need not prevail on every claim presented in an action in order to be considered a successful party within the meaning of the section. (See, e.g.,
Ligon
v.
State Personnel Bd.
(1981)
Once it has been determined that a party is successful and is otherwise entitled to fees under section 1021.5, the court must calculate the amount to be awarded. (See
Press
v.
Lucky Stores, Inc., supra,
34 Cal.3d at pp. 322-323.) The starting point of every award must be a calculation of the attorney’s services in terms of the time expended on the case.
(Id.,
at p. 322.) When computing the time expended, the court should ordinarily consider only time reasonably spent on the merits of the action, and should not include peripheral activities
unless
they may be shown to have contributed to the result reached.
(Mandel
v.
Lackner
(1979)
Under federal law, the hours reasonably expended on an action may include services performed in closely related administrative proceedings. In
Chrapliwy
v.
Uniroyal, Inc.
(7th Cir. 1982)
We recognize that while federal statutes authorize fees “in any action or proceeding” (see, e.g., 42 U.S.C. § 1988), California law more narrowly provides that fees may be awarded “in any action. ...” Relying on that difference and on
Consumer Lobby Against Monopolies
v.
Public Utilities Com.
(1979)
First, a recent decision of the United States Supreme Court,
Webb
v.
Board of Education of Dyer County
(1985) — U.S. — [
In
Webb,
the court emphasized that under the Civil Rights Attorney’s Fees Awards Act (42 U.S.C. § 1988), the determination of the hours “reasonably
*848
expended” upon an action is a matter for the discretion of the trial court.
(Webb, supra,
at pp. --- [85 L.Ed.2d at pp. 241-242, 105 S.Ct. at pp. 1928-1929].) Section 1988 authorizes a fee to the prevailing party in “any action or proceeding” to enforce certain statutes, including 42 United States Code section 1983. At issue in
Webb
was the fee claim of a teacher who had prevailed in a section 1983 action challenging his termination, and who argued that his award should include fees for services performed on administrative proceedings before the local school board. First, the court held that because those proceedings were optional rather than a necessary prerequisite to the section 1983 action, they were not “proceedingfs] to enforce” that section within the meaning of section 1988. The court also rejected the teacher’s alternative theory that the time spent on the administrative proceedings was time “reasonably expended” on the civil rights action itself, because he had made no showing that “any discrete portion of the work product from the administrative proceedings was work that was both useful and of a type ordinarily necessary to advance the civil rights litigation to the state it reached before settlement.”
(Webb, supra,
at p. — [
Furthermore, in Consumer Lobby Against Monopolies v. Public Utilities Com., supra, 25 Cal.3d 891, our Supreme Court held simply that the Public Utilities Commission may not award attorney’s fees pursuant to section 1021.5 in rate-making proceedings, as the section only authorizes an award by a court in an action. (Id., at p. 910.) Neither that narrow holding nor the language of section 1021.5 itself precluded the trial court from determining that the award of fees in this action should include compensation for services rendered in the administrative proceedings, on the ground that those proceedings were in effect part of this action because of the terms of the settlement agreement between the parties.
When the trial court included fees for the services rendered in conjunction with the administrative proceedings, it described those proceedings and this action as “intertwined inextricably.” The court’s description is accurate. According to the memorandum of understanding which settled this action for all practical purposes, respondents’ promise to abandon their claims was contingent in part on the occurrence of those administrative hearings, and the fact that respondents would participate in the hearings was implicit in the agreement. Given the terms of the memorandum, it is also apparent that the legal services performed in those proceedings were both useful and *849 necessary to the ultimate resolution of the action, and directly contributed to that resolution. Under the circumstances, it was well within the range of the trial court’s discretion to determine that the attorney time expended in the administrative hearings was in effect time “reasonably expended” in the action itself. The award was proper. 5
B. Fees for Civil Penalty Action
Appellant also argues that the fee award should not include time spent on the civil penalty action, because it was a separate action in which respondents did not prevail. We disagree. First, a trial court may, in its discretion, determine that time reasonably expended on an action includes time spent on other separate but closely related court proceedings. (See, e.g.,
Bartholomew
v.
Watson
(9th Cir. 1982)
As for the principles applicable when a plaintiff has prevailed on some claims but not others,
Hensley
v.
Eckerhart, supra,
Next, the court instructed, the trial court must determine what fee is reasonable. After multiplying hours reasonably expended times a reasonable *850 rate, the trial court may adjust that product upward or downward in light of the results obtained, among other factors. If plaintiff failed to prevail on claims unrelated to his successful claims, work on the unrelated claims cannot be deemed to be expended in pursuit of the ultimate successful result. In contrast, where a plaintiff’s claims for relief involve a common core of facts or are based on related legal theories, the court should focus on the significance of the overall relief obtained in relation to the hours reasonably expended; where plaintiff has obtained “excellent results,” his or her attorney should recover a fully compensatory fee. (Id., at pp. 434-435 [76 L.Ed.2d at pp. 51-52].)
In light of the foregoing principles, we consider the award of fees for work on the civil penalty action. It is clear that fees were not inappropriate merely because the penalty action was technically a separate action. While that action was not a necessary prerequisite to this action, the two were closely related and involved identical issues. Notwithstanding respondents’ agreement to pay $500 in return for the dismissal of the penalty action, it is apparent that respondents ultimately obtained the precise result which they sought in the instant action, i.e., the suspension of minimum retail milk prices statewide. Under the circumstances, we conclude that the trial court did not abuse its discretion when it determined that the award of fees in this action should include compensation for the work performed on the penalty action.
C. Determination of Reasonable Hourly Rate
Finally, appellant objects to the court’s finding that the 928 hours which Luana Martilla expended in this action were compensable at $60 per hour. Appellant contends that the trial court failed to distinguish between her services before admission to the bar and those thereafter.
When a party is entitled to attorney’s fees under section 1021.5, the trial court must determine a “touchstone” or “lodestar” figure based on a “ ‘careful compilation of the time spent and reasonable hourly compensation for each attorney . . . involved in the presentation of the case. ’ [Citations.]”
(Press
v.
Lucky Stores, Inc., supra,
34 Cal.3d at pp. 321-322.) The court may then increase or reduce that figure by the application of a “multiplier,” after considering other factors about the lawsuit.
(Id.,
at p. 322, and fn. 12.) The experienced trial judge is the best judge of the value of professional services rendered in his or her court. Provided that the court’s determination of that value is based on the lodestar adjustment method, that determination will not be disturbed on appeal unless the ap
*851
pellate court is convinced that it is clearly wrong.
(Serrano
v.
Priest
(1977)
Ms. Martilla’s declarations stated both when she commenced participation in this litigation, and when she passed the bar examination. The record also includes a declaration from an experienced trial lawyer stating that he had read Martilla’s declarations and resume and concluded that $60 an hour was a reasonable fee for her services. Given that record, we must conclude that the trial court did consider when Martilla passed the bar in arriving at a total hourly value for her services. We note also that although respondents requested a trebling of the lodestar or touchstone figure, the trial court concluded that no enhancement was warranted. 6 We find no abuse of discretion in the court’s fee determination.
V
Appellant contends and respondents concede that the judgment must be modified to eliminate provisions relating to enforcement of the award. The court’s anticipation of possible collection problems was premature. (See
Committee to Defend Reproductive Rights
v.
Cory
(1982)
The order appealed from is modified to delete those provisions which direct appellant and others to take steps to effectuate payment of the fee award from certain sources, which declare the fee award to be costs within the meaning of section 1028, and which declare funds appropriated for the operating expenses of the Department of Food and Agriculture to be funds appropriated within the meaning of section 1028. In all other respects, the order is affirmed.
White, P. J., and Merrill, J., concurred.
Notes
Unless otherwise indicated, all further California statutory references are to the Code of Civil Procedure.
Initially, the court awarded fees pursuant to the substantial benefit doctrine. Subsequently, it concluded that respondents were also entitled to fees pursuant to section 1021.5 which became effective January 1, 1978. (See
Woodland Hills Residents Assn., Inc.
v.
City Council
(1979)
Because the Legislature relied heavily on federal precedent when enacting section 1021.5, California courts frequently look to federal decisions when interpreting that section.
(Westside Community for Independent Living, Inc.
v.
Obledo
(1983)
While the court made that statement before the cross-complaints were actually filed, respondents had filed a lengthy memorandum in opposition to the order to show cause re preliminary injunction, in which their arguments were similar to the allegations of their cross-complaint, filed shortly thereafter.
We are aware that in
Beach Colony II
v.
California Coastal Com.
(1985)
Respondents were also awarded attorney’s fees for their work on the fee issue itself; in making that award, the court diminished the touchstone figure by half.
