OPINION

PANELLI, J.

In this case we are called upon to determine whether, as plaintiffs allege, the 1984 Robbins-McAlister Financial Responsibility Act (Stats. 1984, ch. 1322), when considered in relation to the relevant provisions of the Insurance Code pertaining to automobile insurance, fails to provide drivers with adequate procedural due process of law. For the reasons set forth below we hold that plaintiffs' concerns are legally without merit, and are more properly addressed to the Legislature than to the courts.

I. Legislative Framework

California first enacted a financial responsibility law in 1929, which, like those that followed, required all drivers to be "financially responsible" (usually by means of insurance) for any injury they caused while driving. However, enforcement of the requirement was triggered only when the driver was at fault in an accident causing either bodily injury, or property damage in excess of $100 (later amended to $200). Even then, there was no sanction for failing to have insurance if the driver was able to post a bond in an amount determined by the Department of Motor Vehicles (DMV) to be sufficient to meet the likely liability. Failure to either post a bond or provide proof of financial responsibility resulted in suspension of driving privileges.

In 1931, we held this law constitutional as against a substantive due process challenge, specifically that not all drivers could afford to comply with the law, and that negligent wealthy drivers could continue to drive but that not so negligent but less affluent drivers could have their licenses suspended. ( Watson v. Department of Motor Vehicles (1931) 212 Cal. 279 [ 298 P. 481].)

In 1974, the financial responsibility law was amended to require the posting of a bond or the filing of proof of financial responsibility whenever a driver was involved in an accident resulting in either bodily injury, or property damage exceeding $200, regardless of fault. That too was held to be constitutional in light of an uncodified statute declaring that the purpose of the law was not so much to deter negligent drivers, but rather to insure that everyone, negligent or not, was able to compensate for any harm they caused while driving. (Stats. 1974, ch. 1409, § 1, held constitutional in Anacker v. Sillas (1976) 65 Cal.App.3d 416, 421-422 [ 135 Cal.Rptr. 537].)

In 1984, the Legislature, concerned that too many motorists still were not financially responsible, enacted the Robbins-McAlister Financial Responsibility Act (1984 Act). In addition to the requirements of prior enactments, the 1984 act allows a peace officer to request proof of financial responsibility "whenever a notice to appear is issued" for any alleged moving violation. (Veh. Code, § 16028) Failure to provide such proof is itself an infraction. ( Ibid.) However, if it is established that the driver actually was financially responsible at the time in question notwithstanding the lack of written evidence, the citation will be dismissed. (Veh. Code, § 16028, subd. (e).) If such proof is not forthcoming, the driver is subject to a fine ranging from $100 to $240. (Veh. Code, § 16028, subd. (a).) Moreover, within 60 days of that conviction, the driver must provide proof of financial responsibility (and maintain it for three years) or the driver's license will be suspended. (Veh. Code, § 16034)

From the foregoing, it is clear that the 1984 Act significantly increased the need for insurance. Now, for the first time, failure to have written evidence of financial responsibility is itself an offense. Nonetheless, the full implications of the financial responsibility laws cannot be understood without reference to the Insurance Code.

California is a so-called "open rate" state, that is, rates are set by insurers without prior or subsequent approval by the Insurance Commissioner (Commissioner). (Ins. Code, § 1850.) This is not to say, however, that there is absolutely no regulation of the rates. California law does require that rates not be "excessive, inadequate or unfairly discriminatory." (Ins. Code, § 1852) No rate is excessive unless: "(1) such rate is unreasonably high for the insurance provided and (2) a reasonable degree of competition does not exist in the area with respect to the classification to which such rate is applicable." ( Ibid.) Risk classifications are permissible if based on any reasonable (i.e., actuarially sound), and not prohibited, ground. (Ins. Code, § 1852, subd. (d).) Although the term "unfairly discriminatory" is not defined in Insurance Code section 1852, section 11628 of that code prohibits discrimination by an insurer with regard to issuance of policies, or the terms of such policies, on the basis of "race, language, color, religion, national origin, ancestry, or location within the same geographic area." "Geographic area" is defined as an area "not less than 20 square miles," and is made up by combining a series of contiguous zip code zones. Under the statutory scheme, different geographic areas may be treated differently.

Although insurers need not file their rates with the Commissioner, nor obtain approval of rates, the Commissioner may on his own initiative investigate rates. (Ins. Code, § 12924.) Moreover, a person objecting to a rate or classification may file a complaint with the insurer and, if dissatisfied with the insurer's response, file a complaint with the Commissioner. (Ins. Code, § 1858.)

The Commissioner may, at his option, dismiss the complaint without investigation. ( Ibid.) In fact, the Commissioner routinely does so if the complaint fails to come within his perceived jurisdictional powers. A common example of a routinely dismissed complaint is one alleging a refusal by an insurer to provide coverage to an applicant. If the Commissioner does investigate, he may hold public hearings, issue findings, and assess penalties. The decisions of the Commissioner are subject to judicial review. (Ins. Code, § 1858.6.) Should the Commissioner make a determination that the rates are excessive or are not excessive, then the complainant, on request, is entitled to know the basis of such determination. (Ins. Code, § 1858.7.) In this regard, plaintiffs allege that only once in the last decade has the Commissioner declared a rate to be excessive.

In California, in addition to the regular and customary sources for the purchase of insurance coverage which most are familiar with, drivers may be insured through the California Automobile Assigned Risk Plan (CAARP). (Ins. Code, § 11620 et seq.) By statute this plan is available to any driver otherwise entitled to insurance but who has been unable in good faith to obtain it within the past 60 days. (Ins. Code, § 11620; Cal. Admin. Code, tit. 10, ch. 5, subch. 3, art. 8, § 2430.) All insurers are required to participate in the program. (Ins. Code, § 11620) CAARP offers the statutorily required minimum insurance plus optional medical and uninsured motorist coverage. (CAARP, §§ 2406-2408.)

The CAARP rates are set by the Commissioner after public hearings, and are based on a number of classifications (including geographical area). There is a rate differential of $600 between drivers with no accidents or traffic violations in the last three years and those with twelve or more "points" during that period. (Prior to 1987, the differential was $200.) Under CAARP, the highest annual premium for "good drivers" (i.e., those with zero points) is for youthful drivers in the highest rated geographic areas (e.g., South Central Los Angeles). The annual premium for these drivers is $662. For adult drivers in the highest rated geographic area who have zero points, the annual premium is $516. CAARP provides that the premium can be paid in five installments provided a 25 percent deposit is made. In order to use the installment plan an additional $2 fee per installment is charged. (CAARP, § 2443.1.)

In most parts of the state, CAARP rates are higher than those offered by voluntary insurers. However, in certain areas, including the area in which all plaintiffs reside (South Central Los Angeles), CAARP is allegedly less expensive than non-CAARP insurance. It appears that statewide, approximately 35 percent of those with CAARP insurance are drivers with no points.

Being placed with CAARP is really a "nondecision." That is, no entity "decides" to place a driver in the program. Rather, placement in the plan results as a condition of being "unable to procure [insurance] through ordinary means." The inability to procure insurance by ordinary means is, of course, the result of determinations made by individual insurers to refuse to provide coverage to the driver in question. Hence, eligibility for CAARP is not reviewable because there is no decision to review.

II. Factual and Procedural Background of this Litigation

Despite the above differences, all of the named plaintiffs shared some common characteristics. As previously noted, all lived in South Central Los Angeles. None of them had been involved in an accident or had a traffic violation within the last three years or since they started driving. All have had difficulty finding insurers willing to issue them a policy, and none had found private insurance at premiums below those offered by CAARP. Plaintiffs felt that it was unfair to lump them with bad drivers for insurance purposes notwithstanding their clean driving records, and to be charged correspondingly higher premiums as a result. Many could not afford insurance even under the CAARP or would have difficulty paying the CAARP premiums.

The action was brought on behalf of the named plaintiffs and "all others similarly situated," specifically, licensed drivers who do not have the required "insurance or proof of insurance" and "all who have been fined or lost their licenses" pursuant to Vehicle Code section 16034 The class has not been certified.

The defendants are (in their official capacities) George Meese, former Director of the DMV, James Smith, Commissioner of the California Highway Patrol, John Van De Kamp, Attorney General, and Sherman Block, Sheriff of Los Angeles County. Neither the Commissioner nor any private insurer has been named a party defendant in the action.

Plaintiffs filed their complaint on Friday September 13, 1985, and requested a temporary restraining order enjoining the operation of the 1984 Act. The trial court refused to issue the restraining order, but set a hearing date for plaintiffs' motion for a preliminary injunction.

In support of their motion for preliminary injunction, plaintiffs submitted a number of declarations and exhibits. This evidence tended to establish that the level of competition among automobile insurers found elsewhere in the state was lacking in South Central Los Angeles. Most "mainstream" insurers were allegedly refusing to write policies in that area, or would only insure those who already had insurance. Many of the insurers who did offer insurance for the area were said to be "sub-standard," that is, they specialized in high risk customers and hence charged the highest rates. Insurance by mail was also available, but plaintiffs did not discuss this option except to note that such companies "provide no service through agents or offices for acquiring insurance, servicing policies, or handling claims."

Defendants submitted no evidence in opposition to plaintiffs' motion. However, this court may (as did the trial court) infer from enactment of the 1984 Act itself that the Legislature had determined that substantial harm was being caused by uninsured drivers, especially if their victims were not themselves insured.

The trial court denied plaintiffs' motion, finding that a balance of hardships favored defendants. Plaintiffs then petitioned the Court of Appeal for supersedeas. That court denied the petition. We granted the subsequent petition to this court for review, and stayed enforcement of the 1984 Act. We also transferred the appeal, then pending before the Court of Appeal, to this court.

III. The Questions Presented

The scope of our task is greatly narrowed not only by the limited attack made by plaintiffs, but also by the various concessions made by defendants. First and foremost, plaintiffs have expressly and repeatedly confined themselves to two main legal theories: (1) By providing no mechanism whereby a driver can question and challenge (a) an insurer's decision not to issue a policy or (b) the rate thereof, and by effectively making the ability to drive contingent on having insurance, the state is denying drivers procedural due process of law; and (2) By effectively requiring drivers to carry insurance, by allowing insurers to decide who will or will not be able to obtain private insurance, and by failing to provide adequate guidelines to insurers in making their decision, the Legislature has unconstitutionally delegated its authority to insurers.

Similarly, defendants also concentrate on two major points. First, they contend that since the appeal is from a denial of a preliminary injunction we can affirm the trial court solely by balancing the equities without reaching the merits of plaintiffs' claims. Second, they argue that even if we reach the merits and find that there is a procedural due process interest involved, CAARP meets all constitutional standards, and hence the 1984 Act is constitutional. (1) As defendants correctly note, at this stage of the proceedings, i.e., denial of a preliminary injunction, the trial court must be affirmed unless it abused its discretion in making its determination. ( IT Corp. v. County of Imperial (1983) 35 Cal.3d 63, 69 [ 196 Cal.Rptr. 715, 672 P.2d 121].) In exercising its discretion, the trial court must consider "two interrelated factors," specifically, the likelihood that plaintiffs will prevail on the merits at trial, and the comparative harm to be suffered by plaintiffs if the injunction does not issue against the harm to be suffered by defendants (or in this case the people of the State of California) if it does. ( Id. at pp. 69-70.)

Although there is no data quantifying the harm to be caused by issuing the injunction, there is no doubt that the victims of accidents caused by uninsured drivers suffer greatly, especially if these victims do not themselves have medical or uninsured motorist coverage. Against that unquantified harm, the trial court weighed the effect of the law on plaintiffs. Many members of the putative class were undoubtedly faced with fines and threatened with or actually subjected to suspension of their licenses. Without considering the merits, the trial court found that the balance of hardships favored defendants, and therefore denied the injunction.

In doing so, the trial court considered the reasoning of the Michigan Supreme Court in Shavers v. Kelly (1978) 267 N.W.2d 72 [ 267 N.W.2d 72]. That case raised similar issues to those raised here, and is discussed in detail infra. At this point it is necessary only to point out that the Michigan court agreed with plaintiffs' legal position but stayed the effect of its decision for 18 months so that the Legislature could enact appropriate corrective legislation. Inferentially, then, even after the plaintiffs in that case won on the merits the Michigan court must have found that a balance of hardships favored defendants.

However, the procedural posture in Shavers is strikingly different from that in the instant case. In Shavers, the law in question, a no-fault plan which effectively required all drivers to carry insurance, had been in effect, and enforced, for four and one-half years. For the Michigan court to enjoin enforcement would therefore have changed the status quo. In contrast, the 1984 Act had only been in effect for a short time when the trial court heard the preliminary injunction motion. Hence, in the case at bench, an injunction would have maintained the status quo. We therefore conclude that reference to Shavers is of limited value with regard to a balancing-of-hardships analysis.

We conclude that the trial court did not err insofar as it found that the balance-of-hardships analysis favored defendants. However, as previously stated, the trial court must also consider the likelihood of plaintiffs' ultimate success on the merits in determining whether to issue a preliminary injunction. Although consideration of this issue does not entail final adjudication of the ultimate rights in controversy ( Cohen v. Board of Supervisors (1985) 40 Cal.3d 277, 286 [ 219 Cal.Rptr. 467, 707 P.2d 840]), it does affect the showing necessary to a balancing-of-hardships analysis. That is, the more likely it is that plaintiffs will ultimately prevail, the less severe must be the harm that they allege will occur if the injunction does not issue. This is especially true when the requested injunction maintains, rather than alters, the status quo. ( Continental Baking Co. v. Katz (1968) 68 Cal.2d 512, 528 [ 67 Cal.Rptr. 761, 439 P.2d 889].) We believe it is the mix of these factors that guides the trial court in its exercise of discretion.

(2) On review, a trial court's order with regard to a preliminary injunction may be affirmed if either the balance-of-hardships analysis or plaintiffs' likelihood of success considerations would alone support the ruling. ( Cohen, supra, 40 Cal. 3d at pp. 286-287.) However, if the trial court relies on but one of the foregoing, the reviewing court must determine whether that reliance conclusively supports the trial court's determination regardless of the remaining considerations.

Although the balance of hardships favors defendants in this case, we cannot say that it tilts so sharply in their favor that it supports the trial court's order irrespective of the likelihood of plaintiffs' success on the merits, especially where, as here, the trial court's order denying the motion had the effect of altering the status quo. Normally, it would be appropriate to remand the case to the trial court for consideration of the latter question. However, plaintiffs have argued, and we agree, that there exist no contested factual questions necessary to resolve the case. In addition, the legal issues have been exhaustively briefed by the parties and numerous amici. In light of these factors and the importance of the case, we take the unusual, but practical, step of reaching and resolving the merits ourselves.

IV. Discussion

A. Procedural Due Process.

(3) It is well established in California that the privileges conferred by a driver's license constitute an important property right ( Rios v. Cozens (1972) 7 Cal.3d 792 [ 103 Cal.Rptr. 299, 499 P.2d 979]; Bell v. Burson (1971) 402 U.S. 535 [29 L.Ed.2d 90, 91 S.Ct. 1586]), although not so fundamental a right as to trigger a strict scrutiny analysis ( Hernandez v. Department of Motor Vehicles (1981) 30 Cal.3d 70 [ 177 Cal.Rptr. 566, 634 P.2d 917]). It is equally clear that before any criminal sanction is imposed for failure to establish financial responsibility, such as a fine, the state must comply with a panoply of procedures. Moreover, under the 1984 Act, a license can be suspended only after such an adjudication. Hence, at one level, there is ample "due process" before any sanctions are imposed for lack of financial responsibility.

But it is plaintiffs' contention that the foregoing process comes too late. The critical moment, according to plaintiffs' theory, occurs when they attempt to obtain insurance from the private insurance market and are unable to do so. (4) Plaintiffs assert that they have a substantive right either to participate in the private insurance market or to obtain coverage from the private insurance market and it is this right which cannot be impaired without procedural protection. Plaintiffs contend they have a procedural due process right to examine and challenge the decisionmaking process of private insurers.

Plaintiffs' position finds support in Shavers v. Kelly, supra, 267 N.W.2d 72. In Shavers, the Michigan Supreme Court reviewed a legislatively enacted no fault insurance law, which required all drivers to establish their financial responsibility in order to register or operate a motor vehicle. In most other respects, the legislative framework encompassing financial responsibility and insurance regulation was generally similar to that now in place in California. Michigan also had a program similar in many respects to CAARP.

The Shavers court began its consideration by holding that insurers were instruments of the state in carrying out Michigan's no-fault policy, and hence acts by insurers were state acts. Since drivers had a right not to be arbitrarily or capriciously denied by state actions the state-mandated insurance (at fair and equitable rates), the court held that procedural due process was required. At a minimum, that required the state to provide a meaningful way for drivers to challenge an insurer's coverage or rate-setting decision. The court also went on to consider the effect of the Michigan assigned risk program, but concluded that the program did not cure the constitutional infirmity.

Although defendants in the instant case attempt to distinguish Shavers, there is no reasoned way to do so. Thus, if we applied the reasoning of that case here, we would be compelled to find that plaintiffs would likely prevail on the merits. However, we are not persuaded by the reasoning in Shavers, and decline to follow that case in two crucial respects. First, we cannot agree that the acts of private insurers in setting rates or denying coverage are state acts. Second, because of the foregoing, we cannot concur in the Michigan court's summary consideration and rejection of the assigned risk program as a constitutional alternative to meeting due process requirements.

We turn first to the state-action question. We have never held that a private company in a competitive industry is a state agent, or that its decisions on how to price and market its product constituted state action. To the contrary, only in extreme cases of pervasive state regulation coupled with a state-guaranteed monopoly have we equated private decisions with state action.

There are many products and services the use of which is obligatory to the enjoyment of a state-protected property right, such as fire extinguishers for buildings, or smog control devices or mufflers for cars. The state generally should be able to rely on such products to be supplied by the marketplace, and the suppliers should not become state agents on the ground that state law has created or expanded the demand for their product or mandated its use. Rather, it is only when state law encourages the decisionmaking procedure in question, or when a statute permits that which had been prohibited by common law, that the decisions of private parties can potentially be considered state actions. (See Garfinkle v. Superior Court (1978) 21 Cal.3d 265, 278-279 [ 146 Cal.Rptr. 208, 578 P.2d 925] [holding that nonjudicial foreclosure is not state action despite its statutory authorization]; Kruger v. Wells Fargo Bank (1974) 11 Cal.3d 352, 361-362 [ 113 Cal.Rptr. 449, 521 P.2d 441, 65 A.L.R.3d 1266] [refusing to find that the action of a bank in asserting a statutory right of setoff constituted state action].)

Even though the acts of insurers in setting rates and their decisions whether to provide coverage are not state actions, as we have already stated the state's decision to impose a fine or suspend a license is a state action. We must, therefore, consider what process is due to insure that this limited state action is not performed arbitrarily or capriciously.

Plaintiffs contend that the only way to guarantee access to insurance, at "fair and equitable" rates (although not necessarily affordable rates), is to provide the procedural process they request. Defendants do not strongly challenge plaintiffs' contention that by effectively requiring drivers to carry insurance, the state may have a duty to make insurance available to drivers in a manner that is neither arbitrary nor capricious. However, they argue that one way to meet that duty is through the CAARP. We agree.

We are persuaded that we must look to the CAARP in deciding whether the 1984 Act comports with procedural due process. As part of our analysis, we take note of the assessment by the Shavers court of Michigan's Assigned Risk program. That court identified three problems: (1) there was a "statutory presumption that the rates charged will be higher than the rates for motorists in the open marketplace. M.C.L. § 500.3365; M.S.A. § 24.13365." (267 N.W.2d at p. 89.); (2) the rates set by the program were subject to the same procedural and substantive inadequacies as those found in the private market; and (3) there was no way to challenge placement in the program "with its presumptively higher rates." ( Ibid.) Having recited these problems, the court summarily concluded that the program was inadequate to meet due process requirements.

We cannot dispose of CAARP as easily. In determining whether procedural due process is afforded plaintiffs, it is axiomatic that we look only to the asserted state duty and cognizable state action. (See Garfinkle, supra, 21 Cal.3d at pp. 281-282; Kruger, supra, 11 Cal.3d at pp. 366-367.) Thus, if the state provides a program to satisfy its duty, and that program is procedurally adequate, then the "state action" is constitutional. Inasmuch as we have determined (contrary to the Shavers court) that the acts of private insurers do not constitute state actions, we need not consider CAARP in relation to private insurance. Rather, we must look to CAARP standing alone to determine whether it meets the required procedural due process standards.

In our judgment, CAARP effectively guarantees that insurance is offered and available to all eligible drivers in the state. Further, CAARP requires the program's rates to be set by the Commissioner after public hearings. (Ins. Code, § 11620, CAARP, § 2404.) Thus, a plan is in place to meet the state's asserted duty, and the plan is, on its face, procedurally sound. The burden is therefore squarely on the plaintiffs to establish an infirmity in CAARP. In attempting to meet that burden, plaintiffs put forth five arguments (including the three mentioned in Shavers). We ultimately conclude that none has merit.

First, plaintiffs allege that CAARP was originally designed to be used by bad drivers. As a consequence, plaintiffs assert that CAARP rates are "presumptively" higher than those of private insurers. In support, they point to the hearsay words of an official in the Commissioner's office: if CAARP rates are lower than those of private insurers, "something is wrong."

Defendants dispute the accuracy of plaintiffs' premise, but either way it is agreed that 35 percent of those insured through CAARP are drivers with no points and hence are presumptively good drivers. Because of the number of good drivers in the program, CAARP premiums significantly differentiate between drivers with no points and others. (CAARP, § 2460.3 subd. (g).) In addition, even if "something is wrong," as plaintiffs assert, their remedy is through the Commissioner, who may investigate private insurance rates to determine if they are "excessive" or revise the rates set in CAARP. Plaintiffs have made some showing that a "reasonable degree of competition does not exist in [South Central Los Angeles] with respect to the classification to which such rate is applicable." (Ins. Code, § 1852) That is half of the necessary statutory showing required to obtain relief from the Commissioner.

Second, plaintiffs claim that CAARP "stigmatizes the driver vis-a-vis future insurance opportunities." The only evidence on point is a declaration by an experienced, licensed insurance agent who serves the South Central Los Angeles community. However, that declaration does not show that, for purposes of future insurance opportunities, an insurer treats a CAARP driver any differently from a previously uninsured driver. Therefore, we cannot find that CAARP results in unconstitutional state-mandated stigmatization.

Third, plaintiffs complain that they cannot challenge CAARP rates, another concern of the Shavers court. This is true on an individual premium basis at the time of application. However, unlike private insurance rate-setting systems, CAARP rate criteria are set out publicly, so the application of rate classification to an individual premium is a ministerial task and easily verified by the applicant. On a larger scale, rates are set periodically by the Commissioner after public hearings. Consequently, ample process is afforded with regard to CAARP rates and premiums.

Fourth, plaintiffs note that coverage under the CAARP is limited and they cannot choose their carrier. If they desire additional insurance, they must take out a separate and allegedly expensive supplemental policy with another insurer. Even if true, this additional insurance is not required by law, and so the need to obtain it is purely self-imposed. Further, plaintiffs specify no reason, and we can discern none, why the inability to choose a particular insurer renders CAARP constitutionally infirm. This allegation therefore can have no effect on plaintiffs' constitutional challenge.

Finally, as in Shavers, plaintiffs complain that they cannot challenge their placement in CAARP. But as we noted earlier, there is no single decision consigning someone to that program; only individual decisions of insurers to refuse to insure, or to charge rates that the applicant finds unacceptable. Thus, plaintiffs' objection is not to CAARP as such, but to the Commissioner's failure to police the insuring decisions and rate schedules of the private insurers.

In sum, because the acts of private insurers do not constitute state actions, plaintiffs have no procedural due process right to review or challenge an insurer's decision concerning the denial of coverage or the premiums charged. Although state action is involved in the suspension of a license or the imposition of a fine for failure to establish financial responsibility, the scope of the state's alleged duty can at most extend to a duty to provide plaintiffs with the required amount of insurance at rates that are neither arbitrary nor capricious. We therefore conclude that CAARP provides the required access to insurance in a manner that comports with procedural due process.

B. Delegation of Power.

Plaintiffs' second argument is dealt with more easily. (5) They contend that the current regulatory structure in California constitutes a delegation of legislative authority to the private insurance industry, which determines who can purchase insurance (and thus who must resort to CAARP) and what rates they must pay. Such a delegation, plaintiffs maintain, is invalid unless accompanied by clear standards to guide the exercise of the delegated power, and adequate safeguards to limit the exercise of discretion.

However, the great weight of California authority has found a delegation of legislative power to industrial or professional associations only where statutes gave such groups the power to initiate or enact rules that acquired the force of law. Other decisionmaking authority, even if the decision had a significant impact on a person's daily life, has not constituted a delegation.

The exception to the rule is Rosner v. Peninsula Hospital Dist. (1964) 224 Cal.App.2d 115 [ 36 Cal.Rptr. 332]. In Rosner, a hospital adopted an emergency resolution requiring all staff doctors to carry malpractice insurance, and refused staff privileges to Dr. Rosner because he lacked such coverage. The Court of Appeal struck the resolution because it effectively delegated the determination of who could obtain staff privileges to the insurance industry, and it did so without providing adequate safeguards or standards. However, Rosner was rejected in a later Court of Appeal decision also concerning a requirement that all staff doctors carry medical malpractice insurance. ( Wilkinson v. Madera Community Hospital (1983) 144 Cal.App.3d 436 [ 192 Cal.Rptr. 593].) The Wilkinson court, relying on our post- Rosner decision in Wilke Holzheiser, Inc. supra, 65 Cal.2d 349, held that the purported delegation was really no delegation at all. Insurance companies had always been entitled to determine who they would insure. The hospital's rule in no way "authorized a private entity to do anything other than what it was already entitled to do." (144 Cal.App.3d at pp. 445-446.)

We adhere to the longstanding rule that a statute does not delegate legislative authority to a private industry unless it empowers that industry to initiate or enact rules that have legal force. A statute that merely permits a private seller to decide to whom to sell, and at what price, is not unconstitutional.

V. Conclusion

In reaching this conclusion, we are not insensitive to plaintiffs' position. There is a certain appeal to plaintiffs' complaint that those with good driving records, who could possibly afford insurance if they lived in a more affluent area, are unable to obtain insurance in the area where they actually live. As a consequence, they face relatively heavy fines and suspended licenses for a traffic infraction that would otherwise be but a minor annoyance. There is also some persuasive force to plaintiffs' concern that the lack of procedural safeguards in the area of private insurance, which might provide a guaranty that such insurance is offered at fair and equitable rates, leads to a feeling of helplessness among those unable to afford or obtain private insurance. However, their case should be made to the Legislature, not to this court. So long as the legislatively mandated system meets minimum procedural due process standards, as we found it does, we cannot look behind the enacted framework to replace the Legislature's social judgment with our own. To do so would be an egregious violation of the separation of powers.

Our order of December 5, 1985, enjoining enforcement of the provisions of Vehicle Code sections 16028 through 16035 is vacated. The order of the trial court denying the motion for a preliminary injunction is affirmed. The case is remanded for further proceedings consistent with the foregoing opinion.

Lucas, C.J., Arguelles, J., Kaufman, J., and Feinerman, (Robert), J., concurred.
