Opinion
TOBRINER, J.
In 1971, plaintiff Donna R. Schlichting instituted the underlying class action against defendant Civil Service Employees Insurance Company, seeking to recover damages resulting from the defendant’s refusal to pay benefits allegedly owed under a “medical expense” clause contained in an insurance policy. Plaintiff’s complaint alleged that although defendant had agreed to reimburse insureds for all medical expenses incurred as a result of a covered automobile accident, defendant had adopted the practice of refusing to pay any such medical expenses that were also covered by separate health insurance, such as Blue Shield. In response, the insurer defended its practice on two grounds: (1) that in agreeing “to reimburse” insureds for medical expenses, it had clearly and unambiguously limited its obligation to out-of-pocket medical expenses, and (2) that Blue Shield and other health insurance plans constituted “automobile medical payments insurance” within the meaning of an exclusionary clause of its policy.
In the present proceeding, defendant insurer seeks a writ of mandate or prohibition to compel the trial court to vacate two pretrial orders rendered in favor of the plaintiff class in the underlying action. In the initial of the two orders, the trial court granted plaintiff’s motion for partial summary judgment, rejecting as a matter of law defendant’s proposed interpretation of the insurance policy. In the second order, rendered concurrently with the partial summary judgment order, the court ruled, inter alia, that defendant should initially bear the cost of notifying absent class members of the pendency of the action.
Defendant maintains that each of the challenged orders is constitutionally defective under principles of federal due process. Defendant argues that the partial summary judgment order is invalid on the ground that due process precludes a court from ever rendering a decision “on the merits” in a class action before notification to absent class members of the pendency of the action. Defendant asserts that the order requiring it [366]*366initially to bear the cost of notice fails on the ground that requirements of due process prohibit a trial court from ever compelling a defendant “to finance” a lawsuit against itself.
As we shall explain, we have concluded that, contrary to defendant’s assertions, neither court order at issue here succumbs to constitutional attack. First, although defendant now claims that the trial court should have deferred a decision on the partial summary judgment motion until absent class members had been notified of the action, defendant never raised such an objection prior to the trial court’s ruling on the motion. Instead, defendant confined its opposition to a substantive argument on the merits of plaintiff’s motion. Under these circumstances, we conclude that defendant waived whatever constitutional right it may have enjoyed to require the court to postpone determination of the summary judgment motion until after class notification.
Second, while defendant maintains that a trial court lacks authority to order a defendant to bear the initial burden of notifying absent class members of the pendency of the suit, as we explain both a statutory provision of the California Consumer Legal Remedies Act (Civ. Code, § 1781, subd. (d)), and this court’s seminal decision in Vasquez v. Superior Court (1971) 4 Cal.3d 800, 820 [94 Cal.Rptr. 796, 484 P.2d 964, 53 A.L.R.3d 513], explicitly recognize that in a class action proceeding in this state, trial courts are empowered to “direct either party to notify each class member” of the pendency of the action. (Italics added.) Although defendant further contends that this statutorily authorized procedure violates its due process rights, the relevant constitutional authorities establish that the trial court order clearly conformed with governing principles of both substantive and procedural due process.
Accordingly, we conclude that the requested writ should be denied.
1. The facts and proceedings below.
In April 1971, plaintiff Donna R. Schlichting was injured in an automobile accident in Daly City, California. At the time of the accident, plaintiff held a comprehensive automobile and personal liability policy issued by defendant insurance company. Under part II of the policy, entitléd “Expenses for Medical Services,” the insurer agreed “[/jo reimburse [the named insured] for all reasonable [medical] expenses incurred within one year from the date of [an] accident” (italics added) for [367]*367bodily injuries sustained in such an accident. An additional provision of part II, entitled “Other Insurance,” provided, however, that “[i]f the insured has automobile medical payments insurance with another insurer against a loss covered by Part II” (italics added), the insurer’s liability would be reduced in proportion to such other available automobile medical payments insurance.
At the time of the accident, plaintiff did not have any other automobile insurance to cover her medical expenses. She had, however, purchased health insurance from California Physicians’ Service (Blue Shield), and under that insurance plan Blue Shield paid a portion of the medical expenses which plaintiff incurred as a result of the automobile accident.
In May 1971, plaintiff filed a claim with defendant insurer requesting payment of all medical expenses incurred as a result of the accident, including approximately $350 in medical expenses which were covered under the Blue Shield policy. The insurer, while agreeing to pay the out-of-pocket medical expenses which plaintiff had personally paid, rejected the $350 claim for the expenses covered by Blue Shield, taking the position that the medical payment coverage of its policy did not encompass such expenses.
In October 1971, plaintiff filed the underlying class action against defendant insurer on behalf of herself and similarly situated insureds who, within the preceding four years (the applicable statute of limitation period), had had claims for medical payment reimbursement denied by defendant under similar circumstances.1 The complaint set forth the facts described above, attached the insurance policy under which plaintiff was assertedly covered, and alleged that the insurer had breached the contract [368]*368in failing to pay all medical expenses plaintiff had incurred as the result of a covered accident.
Shortly thereafter, defendant filed an answer to the complaint, conceding that plaintiff was insured under the policy attached to the complaint and interposing a general denial to the remainder of the complaint’s allegations. In addition, defendant set forth in its answer a number of ostensible “affirmative defenses” to the action; only two of these affirmative defenses are of significance for this proceeding.2 In its twelfth affirmative defense, defendant asserted that plaintiff’s complaint rested on a misinterpretation of the insuring clause of the medical expense section of the policy, and alleged that the policy’s use of the term “reimburse” made it clear that the insurer’s liability was limited to out-of-pocket medical expenses paid by its insured. In its thirteenth affirmative defense, defendant alleged that plaintiff’s Blue Shield policy constituted “other automobile medical payments insurance” within the meaning of the “other insurance” clause of the policy.
After the filing of the pleadings, the parties repeatedly attempted to agree upon a mutually acceptable stipulation of facts upon which the legal issues of the case could be decided,3 but defendant in June 1975 finally indicated that it would not concur in any such stipulation. Plaintiff’s attorneys thereafter began the task of attempting to identify the members of the class in preparation for bringing the case to trial. For several weeks during the summer of 1975, plaintiff’s attorneys examined defendant’s insurance records for the years 1969-1971 and identified 172 [369]*369insureds who had had claims rejected under circumstances similar to the plaintiff’s case. At this time, however, defendant informed plaintiff that, despite the pendency of the action, defendant had destroyed all records pertaining to pre-1969 medical payment claims.
Shortly thereafter, plaintiff filed the two pretrial motions that ultimately gave rise to the instant writ proceeding. On November 28, 1975, plaintiff filed a motion for certification of the suit as a class action and for an order notifying class members of the suit’s pendency. In this motion, plaintiff advised the court that her attorney had, through review of the records made available by defendant, identified 172 members of her class, but additionally informed the court that defendant had destroyed the relevant records with respect to pre-1969 claims; plaintiff accordingly requested that, at least with respect to notifying potential class members who could not readily be identified because of the destruction of records, defendant should bear the cost of notice, by means of publication or otherwise.
The following week, plaintiff filed an additional pretrial motion, pursuant to section 437c of the Code of Civil Procedure, seeking partial summary judgment with respect to the issues raised by defendant’s twelfth and thirteenth affirmative defenses. As a practical matter this motion requested the court to resolve the principal legal issue presented by the case, namely, whether or not the policy obligated defendant to pay medical expenses which had been incurred by an insured as the result of a covered accident but which were also included within a separate health insurance policy.
Defendant filed separate oppositions to plaintiff’s motions. In response to the request for partial summary judgment, defendant did not claim that the motion was premature or that its consideration should be postponed until absent class members had been notified of the action, but instead simply contested the merits of the motion, arguing that plaintiff’s interpretation of the policy’s medical expense clause was incorrect. In answering plaintiff’s class certification motion, defendant did not assert that it could not properly be required to bear any cost of notice, but merely suggested that the class should be defined in somewhat narrower terms than plaintiff had proposed.
The trial court held a hearing on plaintiff’s pretrial motions on December 17, 1975, and December 31, 1975, and on January 19, 1976, the [370]*370trial court filed the two orders that are challenged in this proceeding. In one order, the trial court granted plaintiff’s motion for partial summary judgment, concluding that plaintiff’s proposed interpretation of the insurance policy was correct as a matter of law, and consequently that defendant’s principal “affirmative defenses” were without merit.
In the other order, the court first certified the case as a class action, indicating that the parties had entered into a stipulation approved by the court as to the proper designation of the class represented by plaintiff. Then, after indicating the form and nature of the notice that was to be given to absent class members, the order directed defendant to “do all work necessaiy for the mailing and publication of notice of pendency of class action” and provided that, as an initial matter, defendant should bear the expense of the cost of notice. The order also stipulated, however, that the cost of notice was a “recoverable cost to the prevailing party in this action” and indicated that, if defendant ultimately prevailed in the action, it would be entitled to recover from plaintiff notice costs up to at least $10,000.4
After the trial court rejected a flurry of subsequent motions urging reconsideration and modification of the January 19 orders,5 defendant [371]*371filed the instant writ proceeding, seeking a writ of mandate or prohibition to compel the trial court to vacate its pretrial orders insofar as such orders granted partial summary judgment to plaintiff class and directed defendant to bear the initial expense of notifying the absent class members of the pendency of the action. Concluding that the issues raised by the petition involved questions of general significance for class action litigation throughout the state, we exercised our discretion and issued an alternative writ. (See, e.g., Babb v. Superior Court (1971) 3 Cal.3d 841, 851 [92 Cal.Rptr. 179, 479 P.2d 379]; Vasquez v. Superior Court, supra, 4 Cal.3d 800, 806-807; Trani v. R. G. Hohman Enterprises, Inc. (1975) 52 Cal.App.3d 314, 316 [125 Cal.Rptr. 34].) Both parties concede that the question of the validity of the trial court’s orders is properly before us. We turn first to defendant’s attack on the partial summary judgment order.
2. By failing to object to the trial court’s determination of plaintiff’s motion for partial summary judgment prior to class notification, defendant waived any right it may have had to postpone such a ruling until after such notice was provided.
In this proceeding, defendant challenges the trial court’s partial summary judgment order solely on procedural grounds, and raises no question as to the substantive merits of that ruling. Accordingly, the validity of the trial court’s interpretation of the insurance policy is not before us and we express no view on that matter. Defendant argues only that, under the due process clause of the federal Constitution, a trial court lacks authority to pass on the merits of a plaintiff’s substantive claim in a class action before notification of the pendency of the action to the absent class members; since the partial summary judgment order in this case was entered prior to such notification, defendant maintains that the order is constitutionally defective.
[372]*372Defendant’s argument is premised largely on two California Court of Appeal decisions, Home Sav. & Loan Assn. v. Superior Court (1975) 42 Cal.App.3d 1006 [117 Cal.Rptr. 485] (Home I) and Home Sav. & Loan Assn. v. Superior Court, supra, 54 Cal.App.3d 208 (Home II). As our court noted last year in summarizing the Home I and Home II decisions in People v. Pacific Land Research Co. (1977) 20 Cal.3d 10, 16 [141 Cal.Rptr. 20, 569 P.2d 125], those decisions concluded “that a defendant in a class action has a due process right to secure a determination of the issues relating to the suitability of the action as a class matter as well as the composition of the class and the form of notice to the members, prior to determination of the merits of the action.”
As we explained in Pacific Land Research, in arriving at this conclusion the Home decisions reasoned that “unless a decision on the merits is postponed until after the class issues are decided, a defendant is subject to ‘one-way intervention,’ which would allow potential class members to elect whether to join in the action depending upon the outcome of the decision on the merits.” (Id.) The Home decisions considered this consequence fundamentally unfair to defendants, noting that while a defendant would be bound by an adverse ruling under collateral estoppel principles, the defendant would not necessarily gain a commensurate victory if it prevailed, since the ruling in its favor would not be binding on class members who had no notice of the proceeding.
In Pacific Land Research we found it unnecessary to examine the validity of the Home decisions’ conclusion that such asserted unfairness to defendants amounts to a denial of due process so as to preclude a trial court from pursuing such a procedure over a defendant’s objection. (Cf. Bernhard v. Bank of America (1942) 19 Cal.2d 807, 812 [122 P.2d 892]; Cartt v. Superior Court (1975) 50 Cal.App.3d 960, 968-969 [124 Cal.Rptr. 376].) In Pacific Land Research we concluded that, even assuming that the reasoning of the Home decisions was sound, such reasoning did not apply to a consumer protection action, such as that case, brought by the Attorney General on behalf of the general public. Consequently, we held in Pacific Land Research that in such a public consumer protection action a trial court could pass on the merits of the case, over a defendant’s objection, even though the allegedly defrauded consumers on whose behalf restitution was sought had not been notified of the action and consequently would not be bound, under res judicata or collateral estoppel principles, by a decision in defendant’s favor. (See 20 Cal.3d at pp. 17-20.)
[373]*373In the instant case, unlike Pacific Land Research, the propriety of the trial court’s action arises in the context of a traditional privately initiated class action, rather than an Attorney General-instituted consumer protection action. Nevertheless, as in Pacific Land Research, we have determined that we again need not pass on the soundness of the Home decisions’ due process analysis because, even if we assume arguendo that such analysis is correct, the partial summary judgment order at issue here nonetheless must be upheld since defendant waived whatever rights may be afforded by the Home decisions.
As we have seen, after plaintiff filed its motion for partial summary judgment defendant did not object to the trial court’s entertainment of the motion prior to class certification but instead simply contested the motion on the merits; at no time prior to the court’s ruling did defendant urge the prematurity of the motion. Not until defendant’s argument on the merits had been rejected by the trial court did defendant complain of the procedural posture of the case and raise the due process argument upon which it now relies. Under these circumstances, we believe that defendant waived whatever due process rights it may have had to object to the court’s resolution of the partial summary judgment motion prior to class notification.
Previous class action authorities, including the Home II decision relied upon by defendant, uniformly support our conclusion that a defendant waives whatever due process rights it may possess when it voluntarily accedes to a trial court decision on the merits of an issue before notice is provided to absent class members. (See, e.g., Home II, supra, 54 Cal.App.3d 208, 212; Colwell Co. v. Superior Court (1975) 50 Cal.App.3d 32, 34-35 [123 Cal.Rptr. 228]; Roberts v. American Airlines, Inc. (7th Cir. 1975) 526 F.2d 757, 762-763, cert. den. (1976) 425 U.S. 951 [48 L.Ed.2d 195, 96 S.Ct. 1726]; Katz v. Carte Blanche Corporation (3d Cir. 1974) 496 F.2d 747, 758-762; Haas v. Pittsburgh National Bank (W.D.Pa. 1974) 381 F.Supp. 801, 805-806.)
As the decisions recognize, there are many reasons why a defendant may be willing, indeed even eager, to forego class notification prior to adjudication of some, or even all, of the principal legal issues in a case. In some cases, for example, a defendant may decide that the sending of notice itself will be detrimental to its interests, sullying its reputation or perhaps leading some class members to be less willing to continue an ongoing relationship with the defendant. In other cases, a defendant may [374]*374want to avoid discovery or other litigation expenses entailed in notification which may be eliminated if the plaintiff’s claim is rejected on the merits at an early stage of the proceeding. Indeed, in the instant case, it may well have been just such considerations (see fn. 3, ante) that led defendant to contest plaintiff’s partial summary judgment motion on the merits, rather than seeking postponement of the court’s consideration of the motion until after notice of the action had been sent to absent class members.
Having chosen to submit the issue to the trial court on the merits, defendant can hardly claim that it is “fundamentally unfair” in a due process sense to accord the trial court’s decision binding effect. Even though a determination of the partial summary judgment issue in its favor may not have been legally binding on unnotified class members, defendant assumed that risk by not raising a timely objection to the trial court’s resolution of the motion before class notification. As the Home II court noted: “If a defendant chooses to run the risk of collateral estoppel on an unfavorable judgment, it is defendant’s right to due process that it hazards . . . .” (54 Cal.App.3d at p. 212.) In the instant case, defendant voluntarily hazarded the risk of an adverse decision on the merits of the pártial summary judgment motion, and may not properly interpose a belated, after-the-fact objection to the trial court’s entertainment of the motion.
Accordingly, we reject defendant’s procedural attack on the trial court’s partial summary judgment order.
3. The trial court did not violate defendant’s due process rights in ordering it to bear the initial cost of notifying the plaintiff class of the pendency of the action.
In addition to challenging the trial court’s partial summary judgment order, defendant attacks the validity of the class certification order insofar as that order requires it initially to bear the cost of notifying absent members of the plaintiff class of the pendency of the action. Pointing out that in most civil actions such notice costs are initially borne by the plaintiff, defendant argues both that the trial court lacked authority to shift such notice costs to a defendant and that, even if the court possessed such authority, its order violates due process by requiring a defendant “to finance” a lawsuit against itself.6
[375]*375In support of its initial contention, defendant relies heavily on one passage from the United States Supreme Court decision in Eisen v. Carlisle & Jacquelin (1974) 417 U.S. 156 [40 L.Ed.2d 732, 94 S.Ct. 2140] (Eisen IV), in which the Supreme Court reversed a federal district court order imposing the cost of notice on a defendant in a federal class action. The Eisen IV court stated: “In the absence of any support under rule 23 [the federal rule governing class action procedure], petitioner’s efforts to impose the cost of notice on respondents must fail. The usual rule is that a plaintiff must initially bear the cost of notice to the class. The exceptions cited by the district court related to situations where a fiduciary duty pre-existed between the plaintiff and defendant as in a shareholder derivative suit. Where, as here, the relationship between the parties is truly adversary, the plaintiff must pay for the cost of notice as part of the ordinary burden of financing his own suit.” (Fn. omitted.) (417 U.S. at pp. 178-179 [40 L.Ed.2d at p. 749].)
Defendant erroneously relies on Eisen IV. As the above quotation from Eisen IV clearly indicates, the Supreme Court’s conclusion that the federal district court had erred in ordering the defendant to bear notice costs in that case rested directly on the terms of rule 23 of the Federal Rules of Civil Procedure. In the absence of specific authorization for such cost-shifting in the provisions of the governing federal rule, the Eisen IV court indicated that the trial court should not properly have cast the very substantial cost of notice involved in that case upon the defendant.
Contrary to the present defendant’s assertion, however, nothing in Eisen IV suggests that any absolute constitutional barrier obstructs such a preliminary cost-shifting order. Indeed, the Supreme Court’s most recent class action decision, Oppenheimer Fund, Inc. v. Sanders (1978) 437 U.S. 340 [57 L.Ed.2d 253, 98 S.Ct. 2380] makes it clear that even under the federal rule a federal district court, in appropriate circumstances, is empowered to require a defendant to bear some of the expense entailed in identifying and notifying absent class members. Thus, the relevant federal authorities [376]*376go no further than to hold that, under the present provisions of federal rule 23, a plaintiff in a federal class action is normally required to bear the “burden of financing his own suit.”
In California, in contrast to the federal realm, the Legislature has specifically authorized trial courts in class actions to impose the cost of notice upon either the plaintiff or the defendant. Civil Code section 1781, subdivision (d), a provision of the Consumer Legal Remedies Act enacted in 1970 to facilitate consumer class actions, explicitly provides that “[i]f the action is permitted as a class action, the court may direct either party to notify each member of the class of the action.” (Italics added.)
Although section 1781, subdivision (d) does not directly apply to the present case because insurance is technically neither a “good” nor a “service” within the meaning of the act (Civ. Code, § 1761, subds. (a), (b)), we expressly held in Vasquez v. Superior Court, supra, 4 Cal.3d 800, 820, that the class action procedures prescribed by the Consumer Legal Remedies Act could and should appropriately be utilized by trial courts in all class actions.7 Numerous decisions since Vasquez have confirmed the applicability of the act’s procedures in class actions which do not strictly fall within the aegis of the act. (See, e.g., Anthony v. General Motors Corp. (1973) 33 Cal.App.3d 699, 703, 707 [109 Cal.Rptr. 254]; Carlson v. Superior Court (1973) 33 Cal.App.3d 640, 649, fn. 1, 651 [109 Cal.Rptr. 240].) Moreover, in enumerating the various provisions of the Consumer Legal Remedies Act by which trial courts should be guided, we specifically identified in Vasquez section 1781, subdivision (d), and its authorization of the imposition of notice costs on either party in a class action. (4 Cal.3d at p. 820.) Thus, under Vasquez, California trial courts clearly possess general authority to impose notice costs on either party, plaintiff or defendant, in a class action.
[377]*377Defendant contends, however, that even if the trial court was authorized under state law to impose notice costs upon it, the order nonetheless fails under the federal due process clause. The gist of defendant’s argument appears to be that insofar as section 1781, subdivision (d), and the Vasquez decision authorize a court to require a defendant “to finance” a lawsuit against itself, the statute and Vasquez deny a defendant “due process of law.” Although defendant does not articulate its constitutional argument in any depth, and indeed does not even indicate whether the alleged constitutional violation flows from a denial of “substantive” or of “procedural” due process, we explain that the order at issue here is not a denial of due process in either sense.
To begin with, neither section 1781, subdivision (d), nor the trial court order at issue here is vulnerable to a substantive due process challenge. As our court has observed on many occasions in recent years, the adoption of efficient class action procedures unquestionably rationally relates to the vindication of a wide range of legitimate public purposes. (See, e.g., Daar v. Yellow Cab Co. (1967) 67 Cal.2d 695, 714-715 & fn. 14 [63 Cal.Rptr. 724, 433 P.2d 732]; Vasquez v. Superior Court, supra; Southern California Edison Co. v. Superior Court (1972) 7 Cal.3d 832, 841-842 [103 Cal.Rptr. 709, 500 P.2d 621].) Thus, in Vasquez we emphasized: “Protection of unwary customers from being duped by unscrupulous sellers is an exigency of the utmost priority in contemporary society. ... A class action by consumers produces several salutary byproducts, including a therapeutic effect upon those sellers who indulge in fraudulent practices, aid to legitimate business enterprises by curtailing illegitimate competition, and avoidance to the judicial process of the burden of multiple litigation involving identical claims.” (4 Cal.3d at p. 808.)
A class action procedure authorizing a trial court to impose notice costs upon a defendant in a particular case serves the same general public policies. In the absence of such a cost-shifting procedure, the class action mechanism might frequently be completely frustrated since the representative plaintiff, whose individual claim will ordinarily be relatively small, may often be unable to afford the initial cost of notifying all absent members of the pendency of the action. (See Note, Managing the Large Class Action: Eisen v. Carlisle & Jacquelin (1973) 87 Harv.L.Rev. 426, 441-442; Comment, Cost Allocation in California Class Actions (1976) 13 Cal. Western L.Rev. 65, 83.) Under such circumstances, a defendant who may have improperly inflicted a small financial loss upon a great number [378]*378of people could succeed in defeating a class action suit without regard to the strength of the plaintiff’s claim. (Cf. Southern California Edison Co. v. Superior Court, supra, 7 Cal.3d 822, 841-842.) In light of the public interest in establishing a procedure that permits such actions to be decided on their merits, such a cost-shifting procedure is neither arbitrary nor irrational and thus does not abridge substantive due process guarantees.
Although defendant vigorously contends that it is unconscionable to require a defendant “to finance” a lawsuit against itself, we know of no principle of law that precludes the state from providing for a division or shifting of litigation costs, prior to judgment, to effectuate legitimate public policies.8 Indeed, notwithstanding defendant’s protestations, the instant order is by no means unusual in requiring a defendant, prior to judgment, to bear some litigation expenses which may aid the plaintiff’s lawsuit.
The widely used civil discovery procedures, for example, very often require a defendant, prior to judgment, to expend significant funds to retrieve and identify information which will prove beneficial to a plaintiff’s case. Although a defendant may, of course, seek a court order to compel the plaintiff to pay such costs (Code Civ. Proc., § 2019, subd. (b)(1)) any such shifting of discovery expenses lies within the sound discretion of the trial court (see Greyhound Corp. v. Superior Court (1961) 56 Cal.2d 355, 383-384 [15 Cal.Rptr. 90, 364 P.2d 266]) and in many cases defendants are required initially to bear substantial discovery costs, costs which might.be characterized as helping “to finance” the plaintiff’s lawsuit.9
Moreover, in a myriad of other contexts, the Legislature has enacted specific provisions which authorize a trial court, prior to judgment, to [379]*379impose the initial cost of various litigation expenses upon either or both of the parties to the litigation. (See, e.g., Evid. Code, §§ 731, subd. (c) (compensation of court-appointed expert witness); 752, subd. (b) (compensation of court-appointed interpreter); 753, subd. (b) (compensation of court-appointed translator); 894 (compensation of court-appointed blood test expert); Wat. Code, §§ 2040-2048 (allocation of reference expenses; see City of Los Angeles v. City of San Fernando (1975) 14 Cal.3d 199, 296-297 & fn. 104 [123 Cal.Rptr. 1, 537 P.2d 1250]).) These numerous examples of well-established procedures authorizing a trial court to allocate prejudgment costs between the parties refute defendant’s contention that the order at issue denies defendant substantive due process.
Defendant apparently contends, however, that even if the notice cost order does not violate substantive due process principles, the order nevertheless violates procedural due process. Although defendant fails to set forth its argument with any clarity, the thrust of the contention appears to be that the trial court order—imposing the initial cost of notice on defendant—constitutes at least an interim and, in view of plaintiff’s limited resources, probably a permanent, “taking” of defendant’s property, and that the authorization of such a “taking” prior to final judgment denies defendant procedural due process.
Although defendant cites no authority in support of its contention that a trial court order regulating parties’ respective responsibilities for on-going litigation expenses constitutes a “taking” or “deprivation” of property, even assuming that such a taking is involved here we find no denial of procedural due process. Although defendant accurately observes that recent constitutional decisions hold that even interim deprivations or takings of property trigger procedural due process requirements (see, e.g., Randone v. Appellate Department (1971) 5 Cal.3d 536, 551-552 [96 Cal.Rptr. 709, 488 P.2d 13]; Fuentes v. Shevin (1972) 407 U.S. 67, 84-86 [32 L.Ed.2d 556, 572-573, 92 S.Ct. 1983]), defendant errs in suggesting that any such taking is unconstitutional unless preceded by a final court judgment. On the contrary, the recent decisions have affirmed that a deprivation is clearly constitutional if, prior to the taking, the party facing deprivation obtains notice and a meaningful hearing as to the propriety of the deprivation. (See, e.g., Skelly v. State Personnel Bd. (1975) 15 Cal.3d 194, 208-211 [124 Cal.Rptr. 14, 539 P.2d 774]; Beaudreau v. Superior Court (1975) 14 Cal.3d 448, 458-459 [121 Cal.Rptr. 585, 535 P.2d 713].)
[380]*380In the instant case, of course, before the trial court issued its order defendant received notice and a full hearing on the issue of who should bear the cost of notifying absent class members of the pendency of the suit. Because defendant has failed to include a transcript of the hearing in the instant record we cannot determine with specificity what issues were discussed by the parties and the court; defendant, however, does not contend that it was denied a complete opportunity to argue against plaintiff’s request that defendant bear the initial cost of notice burden. Under these circumstances we must assume that the trial court considered the wide range of factors that other courts have identified as relevant to the cost allocation decision (see Cartt v. Superior Court, supra, 50 Cal.App.3d 960, 974, fn. 21; Berland v. Mack (S.D.N.Y. 1969) 48 F.R.D. 121, 131-132; Lamb v. United Security Life Company (S.D.Iowa 1972) 59 F.R.D. 25, 38-43),10 and, in light of such factors, exercised its discretion in favor of requiring defendant to bear the cost of notice.11
Defendant appears to argue, however, that despite the fact that it was afforded full notice and a hearing on the cost of notice issue, procedural due process requisites were not satisfied because the court order shifted the initial cost of notice prior to the court’s final determination of the merits of the action. As the numerous statutory procedures governing the imposition of discovery and expert witness costs illustrate, however, procedural due process is not offended by a court order which—after notice and hearing on the factors relevant to the interim cost allocation decision—imposes some of the on-going litigation costs on a defendant [381]*381without a final determination on the merits of the case. Although, as the decisions cited above indicate, the trial court’s preliminary view of the strength of plaintiff’s claim may be a proper factor in the court’s allocation of notice costs, a final judgment on the merits is not a due process prerequisite to an interim court order imposing litigation costs on a defendant. (Cf. Oppenheimer Fund, Inc. v. Sanders, supra, 437 U.S. 340 [57 L.Ed.2d 253, 98 S.Ct. 2380].)
Moreover, the trial court order in the present case is. particularly invulnerable to a procedural due process challenge for, as we have seen, at the time the trial court issued the order the court had already rendered partial summary judgment for plaintiff on two of the principal legal issues raised in the case. Although additional factual questions remained to be litigated, the partial summary judgment order, rejecting defendant’s interpretation of its insurance policy, realistically assured the plaintiff class at least a partial victory in its lawsuit. Under similar circumstances, the United States Supreme Court in Mills v. Electric Auto-Lite (1970) 396 U.S. 375, 389-390 [24 L.Ed.2d 593, 605, 90 S.Ct. 616], expressly recognized that plaintiffs who obtain a partial summary judgment are “entitled to an interim award of litigation expenses. . . .” Thus defendant completely fails to show that the trial court order imposing notice costs on defendant violated due process.
4. Conclusion.
As we have explained, we have concluded that neither of the two pretrial class action orders at issue in this case succumbs to defendant’s constitutional attack. First, in failing to object to the trial court’s consideration of plaintiff’s summary judgment motion prior to class notification, defendant waived any valid constitutional objection it may have had to the trial court’s consideration of the motion at that stage. Second, contrary to defendant’s contention, the trial court order requiring defendant to bear the initial cost of notifying absent class members of the pendency of the action did not violate either substantive or procedural due process.
Accordingly, the alternative writ previously issued is discharged and defendant’s request for a peremptory writ is denied. Plaintiff (real party in interest) shall recover its costs.
