ORDER

This matter comes before the court upon defendant’s motion for summary judgment. The court heard argument on June 28, 2013. Mark Merin appeared for plaintiffs; Krista Whitman appeared for defendant County of Sacramento. Following hearing, the court allowed brief supplemental filings, after which the matter was submitted. After considering the parties’ briefing and arguments at the hearing, the court GRANTS defendant’s motion for summary judgment.

I. BACKGROUND

On February 8, 2011, plaintiffs Sacramento County Retired Employees Association (“SCREA”), Prestwich, Rogers, Harding, Abernathy, Remson and Flores (collectively “plaintiffs”) filed a putative class action complaint against the County of Sacramento (“County”) on behalf of four subclasses 1 of retired Sacramento County employees, challenging the County’s decision to reduce or terminate a health and dental insurance subsidy for several classes of employees. Compl., ECF No. 1. Plaintiffs allege that since 1980, defendant has provided medical and dental insurance subsidies that assisted County retirees with their medical and dental insurance premiums through the Sacramento County Employee Retirement System (“SCERS”). ECF No. 1 ¶2. From 1993 to 2002, the Sacramento Coun *1153 ty Board of Supervisors (“Board”) provided the subsidies “by resolution and set the amount at the highest HMO premium for non-Medicare eligible retirees.” Id. The Board froze the subsidy in 2008 at a maximum of $244 per month for medical insurance and a flat rate of $25 per month for dental insurance premiums, without distinguishing between former employees based on management status or union representation. Id. In 2007, the Board adopted its Retiree Medical and Dental Insurance Program Administrative Policy for 2008, eliminating subsidies for employees who retired after May 31, 2007. Id. ¶ 4. Six unions representing their members who were County employees challenged this action before the California Public Employment Relations Board (“PERB”), which issued a decision on June 30, 2009; according to the complaint, PERB ordered defendant to rescind the subsidy cut. (ECF No. 1 ¶¶ 4-5.) The Board did so, but only for those current and prospective retirees who were represented by the unions in the claim before the PERB. Id. ¶ 8. In 2010, the Board reduced the medical insurance subsidy to a maximum of $144 per month and eliminated the dental insurance subsidy for employees who had retired prior to June 1, 2007. Id. ¶¶ 3, 7. In 2011, the medical insurance subsidy was reduced to a maximum of $80.64 per month. Id. ¶ 3.

Plaintiffs allege four causes of action on behalf of themselves and their putative subclasses: 1) violation of the contract clause of Article I, Section 10 of the U.S. Constitution; 2) violation of the contract clause of Article I, Section 9 of the California Constitution; violation of the Equal Protection Clause of the Fourteenth Amendment to the U.S. Constitution; and 4) violation of the equal protection clause of Article I, Section 7 of the California Constitution. Id.

Defendant filed a motion to dismiss in lieu of an answer on April 1, 2011, arguing there was no express contract, it could not be bound by an implied contract, and it had a rational basis for treating the unionized employees differently. ECF No. 8.

On March 31, 2012, 2012 WL 1082807 , this court denied the motion to dismiss, relying chiefly on the California Supreme Court’s decision in Retired Employees Association of Orange County., Inc. v. County of Orange, 52 Cal.4th 1171, 1194, 134 Cal.Rptr.3d 779 , 266 P.3d 287 (2011) {“REAOC III ”), 2 which found that “under California law, a vested right to health benefits for retired county employees can be implied under certain circumstances from a county ordinance or resolution.” Id. at 1194 , 134 Cal.Rptr.3d 779 , 266 P.3d 287 . See ECF No. 33 at 5. The court also concluded that whether the County could rationally treat the plaintiffs and their putative classes differently than the unionized employees who secured a favorable PERB decision was a question of fact not susceptible to resolution on a motion to dismiss. Id. at 10.

Defendant filed its answer on April 12, 2012. ECF No. 34.

The parties have stipulated to vacating the deadline for filing a class certification motion pending resolution of the instant motion for summary judgment. ECF No. 47.

II. EVIDENTIARY ISSUES

Under Rule 56 this court may consider only admissible evidence in support of or in opposition to summary judgment. “It is well settled that only admissible evidence may be considered by the trial court in ruling on a motion for summary *1154 judgment.” Beyene v. Coleman Sec. Servs., Inc., 854 F.2d 1179 , 1181 (9th Cir.1988); FED. R. CIV. P. 56(c)(2). A court cannot consider inadmissible hearsay in opposition to a motion for summary judgment. Orr v. Bank of America, 285 F.3d 764, 773-74 (9th Cir.2002).

A. Defendant’s Request For Judicial Notice

The County has asked the court to take judicial notice of a number of official records, including SCERS resolutions regarding the health insurance subsidies; staff reports to the Board, also on the topic of the health insurance subsidies; and the PERB decisions stemming from the County’s changes to the subsidies. Defendant’s Req. for Jud. Notice, ECF No. 44.

Under Rule 201 of the Federal Rules of Evidence, a court may take judicial notice of an adjudicative fact which “must be one not subject to reasonable dispute in that it is either (1) generally known ... (2) or capable of accurate and ready determination by resort to sources whose accuracy cannot reasonably be questioned.” Courts have taken judicial notice of a Board of Supervisors’ resolution and of administrative decisions. Merced Irrigation Dist. v. Cnty. of Mariposa, 941 F.Supp.2d 1237, 1261-62 (E.D.Cal.2013) (taking judicial notice of Board of Supervisors’ resolution as matter of public record); Lee v. City of Los Angeles, 250 F.3d 668, 689 (9th Cir.2001) (stating a court may take judicial notice of matters of public record); Mack v. S. Bay Beer Distrib., Inc., 798 F.2d 1279 (9th Cir.1986), disapproved on other grounds by Astoria Fed. Sav. & Loan Ass’n v. Solimino, 501 U.S. 104 , 111 S.Ct. 2166 , 115 L.Ed.2d 96 (1991) (taking judicial notice of an administrative board decision). As plaintiffs do not contest their authenticity, this court takes judicial notice of the documents contained in ECF Nos. 44-1 through 44-5.

B. Plaintiffs’ Exhibits

Plaintiffs’ counsel has submitted a number of exhibits attached to his declaration, including a copy of an article from The Sacramento Bee; a report submitted to the County by CPA Richard Green; the United States Governmental Accounting Standards Board (GASB) Statement 45, referenced in Mr. Green’s report; and literature issued by the County’s Department of Employee Relations and Benefits to new retirees. In addition, counsel reports on the results of questionnaires he mailed to SCREA members in an effort to determine their understanding of the nature of the health insurance subsidy.

The newspaper article plaintiffs offer is hearsay: even if the statement plaintiffs seek to admit satisfies some hearsay exception, the author of the article has not provided a declaration affirming what County Counsel Ryan said. Larez v. City of Los Angeles, 946 F.2d 630, 642 (9th Cir.1991); Green v. Baca, 226 F.R.D. 624, 637-38 (C.D.Cal.2005). At oral argument, counsel conceded the article is hearsay; it is disregarded.

Plaintiffs counsel also attests to the results of a questionnaire he mailed to SCREA members. The results of surveys are not automatically inadmissible; criticisms of the format of the questions or the manner in which the survey was taken generally go to weight, rather than admissibility. See Fortune Dynamic, Inc. v. Victoria’s Secret Stores Brand Mgmt., 618 F.3d 1025, 1036 (9th Cir.2010). In this case, because counsel has not provided the questions, the court is unable to evaluate their format or content. At oral argument, counsel described the questionnaire as “elaborate” and did not dispute opposing counsel’s characterization that it called *1155 for narrative answers. As the court cannot determine from counsel’s description how he derived his conclusions from the narrative responses to the questionnaires, the court will not consider the summary. See Gibson v. Cnty. of Riverside, 181 F.Supp.2d 1057, 1071 (C.D.Cal.2002) (declining to consider a chart under Rule 1006 when the county “ha[d] not even detailed with any particularity the methods employed in the investigation or its results.” (emphasis in original)).

Moreover, even though counsel said he mailed the questionnaire to all the SCREA members he could locate, he does not explain what percentage of County retirees are SCREA members. Accordingly, the fact that 85 percent of those responding believed they were entitled to a lifetime subsidy is of no weight.

III. ANALYSIS

A. Standard

A court will grant summary judgment “if ... there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” FED. R. CIV. P. 56(a). The “threshold inquiry” is whether “there are any genuine factual issues that properly can be resolved only by a finder of fact because they may reasonably be resolved in favor of either party.” Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 250 , 106 S.Ct. 2505 , 91 L.Ed.2d 202 (1986). 3

The moving party bears the initial burden of showing the district court “that there is an absence of evidence to support the nonmoving party’s case.” Celotex Corp. v. Catrett, 477 U.S. 317, 325 , 106 S.Ct. 2548 , 91 L.Ed.2d 265 (1986). The burden then shifts to the nonmoving party, which “must establish that there is a genuine issue of material fact....” Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 585 , 106 S.Ct. 1348 , 89 L.Ed.2d 538 (1986). In carrying their burdens, both parties must “cit[e] to particular parts of materials in the record ...; or show [] that the materials cited do not establish the absence or presence of a genuine dispute, or that an adverse party cannot produce admissible evidence to support the fact.” FED. R. CIV. P. 56(c)(1); see also Matsushita, 475 U.S. at 586 , 106 S.Ct. 1348 (“[the nonmoving party] must do more than simply show that there is some metaphysical doubt as to the material facts”). Moreover, “the requirement is that there be no genuine issue of material fact.... Only disputes over facts that might affect the outcome of the suit under the governing law will properly preclude the entry of summary judgment.” Anderson, 477 U.S. at 247-48 , 106 S.Ct. 2505 (emphasis in original).

In deciding a motion for summary judgment, the court draws all inferences and views all evidence in the light most favorable to the nonmoving party. Matsushita, 475 U.S. at 587-88 , 106 S.Ct. 1348 ; Whitman v. Mineta, 541 F.3d 929, 931 (9th Cir.2008). “Where the record taken as a whole could not lead a rational trier of fact to find for the non-moving party, there is no ‘genuine issue for trial.’ ” Matsushita, 475 U.S. at 587 , 106 S.Ct. 1348 (quoting First Nat’l Bank of Arizona v. Cities Serv. Co., 391 U.S. 253, 289 , 88 S.Ct. 1575 , 20 L.Ed.2d 569 (1968)).

B. Undisputed Facts

As the admissible facts are generally undisputed, the court refers to the Coun *1156 ty’s Statement of Undisputed Facts and in some instances to Plaintiffs’ Separate Statement of Undisputed Facts as the sources of the following factual recitation. The court discusses the impact of any relevant disputed facts in the discussion of the merits below.

In 1977, the County’s Board of Retirement 4 approved a $25 a month health insurance subsidy for retirees for the year 1978 only, but discontinued it for the year 1979. In 1980, the Sacramento County Board of Supervisors approved a plan to provide a premium subsidy to retirees, not to exceed $30 a month, to be paid from the excess earnings account of the retirement fund, which would be subject to annual reaffirmation by the Board of Retirement. Pl.’s Response to Def.’s Statement of Undisputed Facts, ECF No. 48-1 ¶ 1. The resolution giving effect to the subsidy stated it was payable only so as long as there were excess earnings available in the retirement fund. ECF No. 48-1 ¶ 1. The Board of Retirement adopted the resolution and approved it on an annual basis until 1993. Id.; Def.’s Response to PL’s Statement of Undisputed Facts, ECF No. 50 ¶¶ 2-4.

In 1993, the Board of Supervisors issued a resolution that did several things, effective June 30, 1994: it adopted Government Code section 31592.4; changed the funding source for the retirees’ subsidy so it would be paid from excess earnings from the Sacramento County Employees’ Retirement System; noted this arrangement would mean that health care subsidies would remain non-taxable to retirees; and finally resolved it would make annual determinations of the level of the retiree health benefit subsidy, if any. ECF No. 48-1 ¶ 2; ECF No. 44-2 at 18-19; ECF No. 50 ¶ 13. The Board subsequently adopted governing rules for the Retiree Health Care Benefits Program. ECF No. 44-2 at 36-43. Beginning in 1994, the Board adopted a policy to govern eligibility for, and access to, health insurance plans and subsidies for the subsequent year. ECF No. 48-1 ¶ 4.

In 2003, the funding source changed from excess earnings from the SCERS system to allocated charges to County departments. ECF No. 48-1 ¶ 3; ECF No. 44-3 at 83.

In 2006, the Board made changes to the Retiree Medical and Dental Program Administrative Policy, but later rescinded the changes. ECF No. 48-1 ¶ 5.

On June 5, 2007, the Board adopted a Retiree Medical and Dental Insurance Program Administrative Policy for 2008, which provided that those who retired on or before May 31, 2007 would continue to receive the subsidy, but which eliminated the subsidy for all those retiring after May 31, 2007. ECF No. 48-1 ¶ 6; ECF No. 44-4 at 19-20, 26. This change to the policy of providing subsidies to retirees interrupted the practice that had until then been in place for 27 continuous years. ECF No. 50 ¶ 1.

Six unions filed unfair labor practice charges, challenging the County’s failure to meet and confer with union representatives before eliminating the medical and dental insurance subsidy for current employees. ECF No. 48-1 ¶ 6; ECF No. 44-5 at 10. In January 2008, an Administra *1157 tive Law Judge (ALJ) held hearings on all the cases and issued Proposed Decisions in each, concluding generally that the County breached its duty to meet and confer with a number of unions. ECF No. 44-5 at 20-21, 45, 67. The ALJ proposed that the County cease and desist from unilateral implementation of the policy and make those affected by the changes whole. Id. In June 2009, PERB upheld the ALJ’s decisions, finding that the County committed an unfair labor practice by unilaterally implementing the changes in eligibility to participate in the subsidy program without fulfilling its obligation to bargain in good faith, ordering the County to rescind the change, and to make whole those impacted by the unlawful change. ECF No. 44-5 at 4, 26, 50-51. The County complied with the PERB order. ECF No. 1 ¶ 8.

On June 10, 2008, while a final PERB decision was pending, the Board adopted its annual Retiree Health Policy for the year 2009, making no eligibility changes. On August 25, 2009, it adopted the Policy for 2010, reducing the subsidy to a maximum of $144 a month. On September 28, 2010, the Board approved the policy for 2011, this time reducing the subsidy to $80.64. ECF No. 48-1 ¶ 9.

For the last twenty years, since 1993, the Board’s Retiree Health Policies have expressly stated that the Retiree Health Program does not create any contractual, regulatory or other vested entitlement to health care benefits; since 2003, the policies also state that subsidies, if provided, are not a vested benefit. ECF No. 48-1 ¶¶ 12-13. In addition, in the years that the subsidies were approved by the Board of Retirement, the resolutions provided the payments would terminate after one year unless extended. ECF No. 48-1 ¶ 14.

In addition, pension payroll inserts mailed from 1983 to 1997 informed retirees about Board action on the subsidies, always observing that extensions of the subsidy were effective for the period of a year. Decl. of Suzanne Likarich & Ex. 45, ECF No. 43-1. From 1983 to 1986, the inserts say “[t]his extension was granted, effective [date], for a period of one year.” ECF No. 43-1 at 1-3. In 1987 and 1989, the inserts say “[t]his extension was approved for a period of one year.... ” Id. at 4-5. 5 In 1989, the inserts not only notified retirees that the extension was for the period of a year, but also that the subsidy is not a vested benefit and is “provided subject to annual review by the Board and may be cancelled whenever the Board deems it appropriate.” ECF No. 43-1 at 5, 7-9. In 1992, the insert notified retirees that the health insurance subsidy had been reduced, though it was extended at this reduced level for a year. ECF No. 43-1 at 10. During this same time period, letters *1158 from the County’s retirement administrator stated that the plan “does not create any contractual, regulatory, or other vested right or entitlement to either present or future retirees ... to any particular level of subsidization of health care costs, or to subsidization at all.” See, e.g., ECF No. 43-1 at 13, 15, 18. Similarly, employee handbooks stated generally that the subsidy is provided on a year-to-year basis, may be cancelled or not renewed by the Board at any time, and is not a vested benefit; retirement checklists and planning guides provided the same information. See, e.g., ECF No. 43-1 at 24, 26, 38; ECF No. 43-2 at 23 (stating that the insurance offset “[i]s not a vested benefit and may be changed or discontinued by the Board of Supervisors”).

SCREA itself sent periodic newsletters to its members and letters to the Board of Retirement and thereafter to the Board of Supervisors, recognizing that the subsidy “must be reapproved on an annual basis or “respectfully requesting that your Board authorize the continuance of the Health Insurance Premium Subsidy ... and give consideration to increasing the subsidy amount....” ECF No. 43-2 at 56, 62, 64.

C. First and Second Causes of Action

Defendant argues that plaintiffs cannot succeed on a claim under either the state or federal contract clauses because there was no contract between the County and its employees to provide a full health insurance subsidy to employees after their retirement. Def.’s Mem. P. & A, ECF No. 41 at 11.

Plaintiffs argue both that there is an implied contract and implied contractual term, arising from the County’s enactment of the Retiree Premium Subsidy and from “a multitude of acts,” including the County’s practice since 1980 of enacting resolutions providing the subsidy, the county’s intent to use excess earnings to provide a subsidy, the County’s adoption of Government Code section 31592.4 to permit the payment of the subsidy in conformance with the Internal Revenue Code, and the County’s adoption of task force recommendations designed to enhance the County’s ability to guarantee continued subsidies. Pis.’ Mem. P. & A., ECF No. 15 at 9, 16.

i. The Contract Clauses

The constitutions of the United States and California forbid the state from passing laws that impair the obligation of contracts. U.S. CONST. ART. I, § 10, cl. 1; CAL. CONST., ART. 1, § 9. To succeed on the Contract Clause claim, a plaintiff must show that “he or she has a contract with the state, which the state, through its legislative authority, has attempted to impair.” Univ. of Hawaii Prof'l. Assembly v. Cayetano, 183 F.3d 1096 , 1101 (9th Cir.1999). The first inquiry has three parts: “ ‘whether there is a contractual relationship, whether a change in law impairs that contractual relationship, and whether the impairment is substantial.’ ” RUI One Corp. v. City of Berkeley, 371 F.3d 1137 , 1147 (9th Cir.2004) (quoting Gen. Motors v. Romein, 503 U.S. 181, 186 , 112 S.Ct. 1105 , 117 L.Ed.2d 328 (1992)); Hanford Exec. Mgmt. Emp. Ass’n v. City of Han-ford, No. 1:11-cv-0828-AWI-DLB, 2012 WL 603222 , at *6 (E.D.Cal. Feb. 23, 2012); Fourth La Costa Condominium Owners Ass’n v. Seith, 159 Cal.App.4th 563, 584 , 71 Cal.Rptr.3d 299 (2008) (applying same analysis to California contract clause claim). Defendant’s motion addresses only the contractual relationship and relies on several recent cases to argue that no such relationship exists. Plaintiffs counter that the same cases demonstrate there are disputed issues of material fact as to the existence of the contractual relationship, precluding summary judgment.

*1159 ii. Retired Employees of Orange County and its Progeny

The relevant body of case law begins with a suit filed in the Central District by an association of Orange County retirees, challenging that county’s decision to discontinue “pooling” the retirees with active employees to set rates for health care benefits, which ultimately led to higher premiums for the retirees. Retired Emp. Ass’n of Orange Cnty., Inc. v. County of Orange, 632 F.Supp.2d 983 (C.D.Cal.2009) (REAOC I). The district court rejected the retirees’ argument that an implicit promise to continue the pooling arrangement arose from the Memorandum of Understanding (MOU) in that case and reasoned that only “explicit language in statutes or legislative enactments” gives rise to contractual obligations. Id. at 986 .

The retirees appealed to the Ninth Circuit, which certified the following question to the California Supreme Court: “Whether, as a matter of California law, a California county and its employees can form an implied contract that confers vested rights to health benefits on retired county employees.” See Retired Emp. Ass’n of Orange Cnty. v. County of Orange, 610 F.3d 1099, 1101 (9th Cir.2010) {REAOC II).

The California Supreme Court’s decision answering the certified question is the first of the cases cited by both parties. In that case, REAOC III, the court concluded:

52 Cal.4th at 1176-77 , 134 Cal.Rptr.3d 779 , 266 P.3d 287 . The court began its analysis with an examination of California’s law of contracts, observing that contracts may be either express or implied and that even a written contract may include implied terms “derived from experience and practice.” Id. at 1178-79 , 134 Cal.Rptr.3d 779 , 266 P.3d 287 (quoting Scott v. Pac. Gas & Elec. Co., 11 Cal.4th 454, 463 , 46 Cal.Rptr.2d 427 , 904 P.2d 834 (1995)). It continued that implied terms generally are treated the same as express terms, “provided that, ‘as a general matter, implied terms should never be read to vary express terms.’ ” Id. at 1179, 134 Cal.Rptr.3d 779 , 266 P.3d 287 (quoting Carma Developers (Cal.), Inc. v. Marathon Dev. California, Inc., 2 Cal.4th 342, 374 , 6 Cal.Rptr.2d 467 , 826 P.2d 710 (1992)). The court then turned to the certified question, which asked the court to decide, as relevant here, whether counties can form implied contracts with their employees and whether implied contracts can create vested rights. Id. at 1179, 134 Cal.Rptr.3d 779 , 266 P.3d 287 . 6

In answering the first question, the court said that “[w]here the relationship [between the county and the employees] is governed by a contract, a county may be bound by an implied contract (or by implied terms of a written contract), as long as there is no statutory prohibition against *1160 such an agreement.” Id. at 1183 , 134 Cal. Rptr.3d 779 , 266 P.3d 287 (emphasis and parentheses in original). The court then turned to Government Code section 25300, which provides that a county board of supervisors may fix compensation of county employees by resolution or ordinance, and concluded that “a court must look to Board resolutions, including those resolutions approving or ratifying MOU’s ... to determine the parties’ contractual rights and obligations.” Id. at 1184-85 , 134 Cal.Rptr.3d 779 , 266 P.3d 287 . The court added it did not need to decide whether a county may form an implied contract on terms of compensation, because the retirees argued they sought recognition of an implied term of a contract; it continued, “[t]hat matters of compensation must be addressed by resolution does not necessarily bar recognition of implied terms concerning compensation.” Id. at 1185 , 134 Cal.Rptr.3d 779 , 266 P.3d 287 . Nevertheless, the court said that a resolution by a county board generally does not establish contract rights because a resolution is generally a means to effect policy. Id. It gave two examples of when legislation does create contracts. First, “[w]here ... the legislation is itself the ratification or approval of a contract, the intent to make a contract is clearly shown.” Id. at 1187 , 134 Cal.Rptr.3d 779 , 266 P.3d 287 . Second, ‘“a legislative intent to grant contractual rights can be implied from a statute if it contains an unambiguous element of exchange of consideration by a private party for consideration offered by the state.’” Id. at 1186 , 134 Cal.Rptr.3d 779 , 266 P.3d 287 (quoting Cal. Teachers Ass’n v. Cory, 155 Cal.App.3d 494, 505 , 202 Cal.Rptr. 611 (1984)). The court concluded that “legislation in California may be said to create contractual rights when the statutory language or circumstances accompanying its passage clearly ... evince a legislative intent to create private rights of a contractual nature enforceable against the [governmental body].” Id. at 1187, 134 Cal. Rptr.3d 779 , 266 P.3d 287 (internal citation, quotation omitted, alteration in original). The court cautioned, however, that “[a] court charged with deciding whether private contractual rights should be implied from legislation ... should ‘proceed cautiously both in identifying a contract within the language of a ... statute and in defining the contours of any contractual obligation,’ ” so that “neither the governing body nor the public will be blindsided by unexpected obligations.” Id. at 1188-89 , 134 Cal.Rptr.3d 779 , 266 P.3d 287 (quoting Nat’l R.R. Passenger Corp. v. Atchison, Topeka & Santa Fe Ry. Co., 470 U.S. 451, 466 , 105 S.Ct. 1441 , 84 L.Ed.2d 432 (1985)). Accordingly a court must presume that legislation is not intended to create contractual or vested rights; the party who claims an ordinance creates a contract has the burden of overcoming the presumption. Id. at 1186, 134 Cal.Rptr.3d 779 , 266 P.3d 287

In the second part of its opinion, the California Supreme Court rejected the county’s argument that it was impermissible to infer vested rights 7 and said that “[vjesting remains a matter of the parties’ intent” and can arise by implication. Id. at 1189-90 , 134 Cal.Rptr.3d 779 , 266 P.3d 287 . It noted that whether the retirees had a contractual right to be part of a unified pool that vested when they retired was beyond the scope of the Ninth Cir *1161 cuit’s question, but said that “as with any contractual obligation that would bind one party for a period extending far beyond the term of the contract of employment, implied rights to vested benefits should not be inferred without a clear basis in the contract or convincing extrinsic evidence.” Id. at 1191 , 134 Cal.Rptr.3d 779 , 266 P.3d 287 .

After receiving the Supreme Court’s decision, the Ninth Circuit remanded the case to the district court “for further proceedings consistent with the answer provided by the California Supreme Court.” Retired Emp. of Orange Cnty. v. County of Orange, 663 F.3d 1292 (9th Cir.2011) {REAOC IV). The district court again rejected the retirees’ claim. Retired Emp. of Orange Cnty. v. County of Orange, Case No. SACV 07-1301 AG (MLGx), 2012 U.S. Dist. LEXIS 146637 (C.D.Cal. Aug. 13, 2012) (REAOC V). An appeal of this ruling is pending in the Ninth Circuit. Retired Emp. of Orange Cnty. v. County of Orange, No. 12-56706 (9th Cir. Sep. 17, 2012) {REAOC VI).

In another recent case, Harris v. County of Orange, 682 F.3d 1126 (9th Cir.2012), the Ninth Circuit considered a challenge to Orange County’s determination to restructure the retirees’ grant to be applied to their health insurance premiums, brought not by REAOC, but by a different group of retirees. The terms and conditions of the grant were contained in sections of the MOU between the county and its active and retired employees and in personnel resolutions for those employees not represented by a union. Id. at 1129 . After the county adopted changes to the grant, the retirees filed suit, alleging that the grant was an implied term of the MOU and that they had a contractual right to receive it because its terms were part of the respective MOUs in effect when they retired. Id. at 1130 .

The Ninth Circuit first opined that “[i]n order to state a claim for a contractual right to the Grant, the Retirees must plead specific resolutions or ordinances establishing that right.” Id. at 1134 . It said the retirees had not done so, but had asked the court to take judicial notice of a number of MOUs, two of which were accompanied by board resolutions adopting them. Id. at 1135 . The Circuit found these MOUs did not help the retirees satisfy the pleading requirement because “[tjhere are no terms or provisions in the MOUs, or in the Board resolutions adopting them, that guarantee the Grant will continue as the Grant existed in the MOUs in place on the dates of retirements. Further, the referenced MOUs, including those adopted by the Board of Supervisors, contain durational language.” Id. at 1135 . Typical of the durational clauses was this language: “This Memorandum of Understanding sets forth the terms of agreement reached ... for the period beginning July 23, 1993 through June 23, 1994.” Id. at 1135 n. 4.

The retirees in Harris argued that the durational terms were “merely generic statements” that should not be considered for purposes of a motion for judgment on the pleadings. The Ninth Circuit disagreed:

Id. at 1135 . The Circuit did find that the district court should have granted the re *1162 tirees leave to amend because there were other MOUs adopted by the board that might provide a basis for their claim. Id.

The Ninth Circuit returned most recently to the issue of public employee rights in Sonoma County Association of Retired Employees v. Sonoma County, 708 F.3d 1109 (9th Cir.2013). In that case, the Association alleged the county had breached an obligation to provide vested healthcare benefits in perpetuity. The district court dismissed the original complaint because the Association had not identified resolutions or ordinances creating an express contract for healthcare benefits. Id. at 1113 . The Association then sought to amend, offering copies of resolutions, MOUs and ordinances, and stating it would provide evidence of the county’s intent “through the testimony of the employees who drafted the County’s resolutions and policies, and through a member of the Board of Supervisors, who would testify as to the Board’s promises and intent....” Id. The district court nevertheless dismissed the complaint without leave to amend and the Association appealed.

On appeal, the Circuit began by examining REAOC Ill’s resolution of the certified question and from that distilled the pleading requirements for the claim before it: the “complaint must plausibly allege that the County: (1) entered into a contract that included implied terms providing healthcare benefits that vested for perpetuity; and (2) created that contract by ordinance or resolution.” Id. at 1115 . 8 The Circuit found the Association had satisfied the first of the requirements by alleging that the board had ratified MOUs, which included provisions for county contributions toward retiree health premiums for those hired after 1990 who had worked for the county for at least ten years; and that the benefits were vested for perpetuity based on the county’s “long-standing course of conduct” and claims that employees who had drafted various documents would testify about the background and intent. Id. at 1116 . It found, however, that the Association had not plausibly pointed to a resolution or ordinance that created the contract implying the benefits and so returned the case to the district court to permit plaintiffs to amend the complaint. Id. at 1118 .

in. Application of Law to this Case

a. Alleged Express Contract

As noted above, in the complaint, plaintiffs allege “there existed a contract between the COUNTY and its employees (now Plaintiff retirees) to provide a substantial health subsidy to its employees upon their retirement, which constituted deferred compensation during the employment relationship that vested upon retirement.” ECF No. 1 ¶¶ 50, 55 (capitalization in original). In their opposition to the motion for summary judgment, plaintiffs argue there is an implied contract arising from “a multitude of acts.” They acknowledge that the legislation effectuating the subsidy “does not itself expressly provide for indefinite entitlement to the subsidy,” but argue that implied terms can be inferred from evidence derived from experience and practice. ECF No. 48 at 10.

In their Separate Statement of Undisputed Facts, plaintiffs aver that under various contracts between the County and the County-sponsored medical plans, SCERS was required to maintain a minimum level of subsidy for the retirees’ medical coverage. ECF No. 48-2 ¶ 5. They cite to a report provided to the Board of Supervi *1163 sors by the Retiree Health Benefit Task Force concerning Government Code section 31592.4. The report said that “[ejxisting contractual arrangements -with your Board and the Sacramento County-sponsored medical plans require a minimum level of subsidies for SCERS retirees’ medical plan coverage,” and suggested that should the subsidies be discontinued, these contractual rights might be violated. ECF No. 44-2 at 3. Plaintiffs have not presented copies of any such contracts, or pointed to anything else in the record supporting their claim that these contracts existed, or explained how their alleged status as third party beneficiaries of such contracts fits within the framework of the REAOC cases. Plaintiffs thus have not raised a disputed issue of fact regarding the existence of an explicit contract. Moreover, the same report provided to the Board of Supervisors confirms this conclusion; it says that “[p]rovision of these health benefit subsidies has been on an ‘annual review’ basis. They are not legally considered ‘vested’ benefits. They may be lowered or eliminated entirely whenever the SCERS Board deems it to be prudent, appropriate and necessary, e.g., whenever excess interest earnings are inadequate or nonexistent. Annuitants are advised annually of the tentative nature of these benefits.” ECF No. 44-2 at 1.

b. Retirement Fund Earnings

Next, plaintiffs have presented the declaration of John L. Benbow, who served on the County Board of Retirement from 1980 through 1986 and who avers that the Retirement Board would intentionally underestimate the expected earnings of the retirement fund every year, which then resulted in a surplus when compared to actual earnings, which in turn were used to fund the health insurance subsidy. ECF No. 48-8 ¶¶ 2-4. Benbow avers that he does not know when this practice was discontinued and asserts his belief that the Retirement Board’s actions reflect County policy. ECF No. 48-8 ¶ 6. Plaintiffs have presented no other evidence suggesting that this practice was in fact County policy; nor do they point to any authority that a practice admittedly discontinued at some unknown time gives rise to an implicit promise to fund the subsidy in perpetuity. Moreover, even Benbow describes this method as a matter of policy and says nothing about the Board’s ratification of the practice in ordinance or resolution. See REAOC III, 52 Cal.4th at 1185 , 134 Cal.Rptr.3d 779 , 266 P.3d 287 (“ ‘Policies, unlike contracts, are inherently subject to revision and repeal ....’”) (quoting Natl R.R. Passenger Corp., 470 U.S. at 466 , 105 S.Ct. 1441 ).

c. Legislation

Former County Executive Robert E. Smith declares he believes and believed that legislation drafted by the Retiree Health Insurance Task Force and adopted by the Board in 1991 would guarantee retirees’ access to the subsidy and provides a letter expressing that belief; he does not, however, attach the legislation he discussed in that letter. Deck of Robert E. Smith, ECF No. 48-17 ¶ 3. At argument, plaintiffs clarified that the legislation Robert E. Smith referenced was the County’s adoption of the resolution making the provisions of Government Code section 31592.4 operative in the county which, according to the report, would bring the County in compliance with IRS requirements. See ECF No. 44-2 at 2. Plaintiffs have presented nothing else showing that the County’s ultimate determination to make Government Code section 31592.4 operative and Task Force’s examination of ways to fund the premium subsidy “if any” translates to a contractual promise to fund the subsidy in perpetuity. ECF No. 44-2 at 18. Indeed, the Resolution adopting the *1164 Rules for the Retiree Health Care Benefits Program says that the Board deems it “necessary to comply with federal tax law in order to preserve the tax qualified status of the retirement plan; and also intend to provide the benefits established hereunder without creating any contractual, regulatory or other vested entitlement thereto in present or future retirees.... ” ECF No. 44-2 at 36. The Rules adopted by this resolution also say that they were intended to ensure that the annual subsidy complies with federal law and “to prevent the vesting ... of any right to payment of the cost of future health care benefits....” ECF No. 44-2 at 38.

Gary Cassady was a member of the Retiree Health Insurance Task Force, which contracted with a consulting group to provide twenty-year cost estimates for retiree health plans. The task force also prepared legislation, which the Board enacted in 1993, effective 1994. Deck of Gary Cassady, ECF No. 48-9 ¶¶2, 4, 6. Although Cassady says he believed that the legislation “would effectively guarantee” the subsidy because it would be drawn from a more stable funding source, the legislation itself says that the Board and its retirement system deem it necessary to comply with federal tax law and “intend to provide the benefits established hereunder without creating any contractual, regulatory or other vested entitlement thereto in present or future retirees, their spouses or dependants.” Compare ECF No. 48-9 ¶ 5 with ECF No. 48-11 at 5. As noted, the resolutions adopted in the wake of this report explicitly deny any intent to create a vested benefit. Mr. Cassady’s declaration does not establish a disputed issue of fact. See Virtusio v. Fina. Indus. Reg. Auth., No. 12-cv-00602 NC, 2013 WL 1899830 , at *6 (N.D.Cal. May 7, 2013) (“‘The issue is whether the employer’s words or conduct, on which an employee reasonably relied, gave rise to that specific understanding.’ ”) (quoting Guz v. Bechtel Nat. Inc., 24 Cal.4th 317, 342 , 100 Cal.Rptr.2d 352 , 8 P.3d 1089 (2000)) (emphasis in original).

d. GASB Provisions

In 2006, the County sought the opinion of CPA Richard Green about the impact of Government Account Standards Board (“GASB”) provisions on the retiree health insurance program. Deck of Mark Merin, ECF No. 48-3 ¶ 3. Plaintiffs’ counsel quotes selectively from Mr. Green’s analysis to suggest that the GASB accounting requirements imposed an obligation on the county. In the introduction to the report, however, Green said, “[b]ecause funding the Program requires annual authorization from the County Board of Supervisors and there are no vested benefits associated with the Program nor have the County management made any guarantees or promises to continue the Program, we believe the County does not have a legal obligation to continue the Program.” ECF No. 48-5 at 2. Green concluded that for purposes of accounting and financial statement reporting, the plan exists as a mutual understanding between the County and the retirees. Id. at 3. Even this latter conclusion does not raise a disputed issue of fact as to the County’s intent, as there is no indication in the evidence that Green was authorized to speak for the County. See City of San Diego v. Haas, 207 Cal.App.4th 472, 495 , 143 Cal.Rptr.3d 438 (2012) (statements by city’s retirement board could not give rise to implied contract for benefits because the court could “only look to whether the City Council, and not SDCERS, intended to grant vested rights .... ”).

e. Retiree Declarations

Plaintiffs have also offered declarations from retirees, who say that they were assured that the subsidy would become vest *1165 ed upon retirement and that they accepted County employment in part on that promise or that retirement counselors assured them “not to worry about language pertaining to discontinuation of the subsidy, because there was no reason to suspect it would be discontinued as long as retirement benefits remained the same, even if the County experienced a “ ‘bad’ year” or that retirement counselors did not inform retirees of the potential that the subsidy might be discontinued.” See, e.g., Decl. of Penelope Clark, ECF No. 48-12 ¶ 2; Decl. of Judy Cook, ECF No. 48-13 ¶¶2-3; Decl. of Donald Savage, ECF No. 48-15 ¶ 2. Plaintiffs have presented only one unequivocal statement from a human resources employee that the subsidy would vest upon retirement; the other, attributed to a retirement counselor, explicitly acknowledged that the benefit had to be renewed from year-to-year, but claimed that this was merely a formality. This falls short of the “significant probative evidence tending to support [their] claim that material, triable issues of fact remain.” Sanchez v. Vild, 891 F.2d 240, 242 (9th Cir.1989) (internal citation, quotation omitted). Moreover, plaintiffs have not shown that these County employees were authorized to speak for the County or otherwise bind it.

f. Recruitment

In addition, Robert T. Smith, who was employed by the County Health Department, notes that it was difficult to recruit medical personnel because of the County’s low salaries and that the subsidy was used as a recruiting tool. Decl. of Robert T. Smith, ECF No. 48-19 ¶¶2-4. 9 Smith’s vague claim that the benefits were used as a recruiting tool is not supported by any recruiting materials prepared by the County promising the subsidy in perpetuity.

g. Implied Promise

None of the evidence reviewed above creates a disputed issue of material fact on the question whether the County created a contract that provided the subsidy to retirees with an implied term that the subsidy was vested in perpetuity. The undisputed evidence shows that although the Board consistently ordered the subsidy to be paid over a period of time, it did so by adopting a policy, not a MOU or other contract. See REAOC III, 52 Cal.4th at 1187 , 134 Cal.Rptr.3d 779 , 266 P.3d 287 (“Where, for example, the legislation is itself the ratification or approval of a contract, the intent to make a contract is clearly shown.”). 10 See also Requa v. Regents of the Univ. of Cal., 213 Cal.App.4th 213, 227 , 152 Cal.Rptr.3d 440 (2013) (finding that Livermore Laboratory retirees sufficiently pleaded the existence of an implied contract for health benefits by showing the Regents authorized insurance coverage for retirees and offered to provide that coverage to Livermore retirees through benefit booklets and handbooks published by their authorized representatives).

*1166 It is true that a course of conduct may show an implied promise, but “the very heart of this kind of agreement is an intent to promise,” Gorlach v. The Sports Club Co., 209 Cal.App.4th 1497, 1507 , 148 Cal.Rptr.3d 71 (2013) (internal citation omitted), and so the conduct alleged to provide the implied contract must give rise to the specific understanding sought to be enforced. Guz v. Bechtel Nat’l., Inc., 24 Cal.4th 317, 352 , 100 Cal.Rptr.2d 352 , 8 P.3d 1089 (2000); see also Foley v. Interactive Data Corp., 47 Cal.3d 654, 679 , 254 Cal.Rptr. 211 , 765 P.2d 373 (1988); CAL. CIV. CODE § 1621. The County has presented evidence showing it did not have the intent to promise. Plaintiffs’ belief that they were entitled to receive the benefit for life is insufficient. Gateway Rehab & Wellness Center, Inc. v. Aetna Health of Cal., Inc., No. SACV 13-0087-DOC (MLGx), 2013 WL 1518240 , at *3 (C.D.Cal. Apr. 10, 2013) (stating that “ ‘the assumption, intention or expectation of either party alone, not made known to the other, can give rise to no inference of an implied contract’ ”) (quoting Travelers Fire Ins. Co. v. Brock & Co., 47 Cal.App.2d 387, 392 , 118 P.2d 25 (1941)). The course of conduct in this case does not give rise to the specific understanding that the subsidy was part of the contractual exchange of labor for compensation in light of the County’s continued stance that the subsidy was not guaranteed. Plaintiffs have offered nothing suggesting that a course of conduct with explicit restrictions can give rise to a unrestricted specific understanding. See Harris, 682 F.3d at 1135 (stating that the durational clause in a MOU “surely cannot be the source of a claim that the benefits survive indefinitely”).

Plaintiffs argue that in Sonoma County , the Ninth Circuit rejected Harris when, as here, a plaintiff relied on implied in fact contract rights. Plaintiffs read Sonoma County in too limited a fashion. In discussing Harris , the Ninth Circuit recognized that “the express terms of the MOUs and resolutions at issue do not establish a specific end date to healthcare benefits, and the Association alleges that the right to healthcare benefits in perpetuity is an implied term of a contract, not an express contractual right.” Sonoma Cnty., 708 F.3d at 1119, n. 7 . The court thus did not say a durational clause is irrelevant when a party alleges that there is an implied term granting retirees the right to benefits in perpetuity.

h. Collective Bargaining

At hearing, plaintiffs argued that the subsidy is a mandatory subject of bargaining. Under California Government Code section 3505, “[t]he governing body of a public agency ... shall meet and confer in good faith regarding wages, hours, and other terms and conditions of employment with representatives of such recognized employee organizations ... and shall consider fully such presentations as are made by the employee organization ... prior to arriving at a determination of policy or course of action.” See Coachella Valley Mosquito & Vector Control Dist. v. California Public Emp’t. Relations Bd., 35 Cal.4th 1072, 1083 , 29 Cal.Rptr.3d 234 , 112 P.3d 623 (2005). Indeed, the PERB upheld the ALJ’s conclusion that the County’s refusal to bargain constituted an unfair labor practice. Yet the fact that something might be a mandatory subject of bargaining does not mean a bargain was struck or that the subject of bargaining becomes part of a contract absent the Board’s adoption of an MOU including terms guaranteeing the subsidy. As noted above, plaintiffs have presented no MOUs in opposition and their own evidence shows that the subsidy was not a bargained-for provision: retired Deputy Sheriff Robert Denham, Jr. avers that he attended at least five different bargaining sessions, *1167 and that one of the top demands was retiree health benefits because the bargaining units wanted to ensure that benefits were protected. Decl. of Robert Denham, Jr., ECF No. 48-14 ¶¶ 2-3. At each session, the County refused to discuss the subsidy, taking the consistent position that the subsidy “would not be in the contract and would not be a subject of bargaining.” ECF No. 48-14 ¶ 4. This position is manifested by the policies themselves, which say nothing about any bargained-for exchange. None of plaintiffs’ evidence clearly evinces the County’s intent to enter into a contract for payment of the health insurance premium subsidy in perpetuity.

Defendant is entitled to summary judgment on the first and second causes of action.

D. Third and Fourth Causes of Action

Section one of the Fourteenth Amendment provides that no state shall “deny to any person within its jurisdiction the equal protection of the laws.” U.S. CONST, amend. XIV, § 1. Section 7(a) of Article I of the California Constitution provides: “A person may not be ... denied equal protection of the laws.... ” CAL. CONST, art. I, § 7(a). “California courts read the rationality review component [of] the Equal Protection clause contained in Article I, section 7, of the California Constitution as ‘coextensive with its federal counterpart.’ ” Katz v. Children’s Hosp., 28 F.3d 1520 , 1529 n. 9 (9th Cir.1994) (quoting Dept. of Developmental Servs. v. Ladd, 224 Cal.App.3d 128, 129 , 273 Cal.Rptr. 485 (1990)); see also Safeway Inc. v. City & Cnty. of San Francisco, 797 F.Supp.2d 964, 971 (N.D.Cal.2011) (“The equal protection provision of the California constitution is substantially the same as the equal protection clause of the Fourteenth Amendment to the United States Constitution and, thus, may be analyzed under the same standard.”).

States may “treat different classes of persons in different ways”; however, classifications “must be reasonable, not arbitrary, and must rest upon some ground of difference having a fair and substantial relation to the object of the legislation, so that all persons similarly circumstanced shall be treated alike.” Reed v. Reed, 404 U.S. 71, 75-76 , 92 S.Ct. 251 , 30 L.Ed.2d 225 (1971) (internal citations and quotation omitted); see also Creighton v. Regents of the Univ. of Cal., 58 Cal.App.4th 237, 246 , 68 Cal.Rptr.2d 125 (1997) (“Equal protection requires that persons similarly situated with respect to the legitimate purpose of the law receive like treatment.”).

Here, rational basis scrutiny applies. Nordlinger v. Hahn, 505 U.S. 1, 10 , 112 S.Ct. 2326 , 120 L.Ed.2d 1 (1992) (“unless a classification warrants some form of heightened review because it jeopardizes exercise of a fundamental right or categorizes on the basis of an inherently suspect characteristic, the Equal Protection Clause requires only that the classification rationally further a legitimate state interest.”). “In general, the Equal Protection Clause is satisfied so long as there is a plausible policy reason for the classification, the legislative facts on which the classification is apparently based rationally may have been considered to be true by the governmental decisionmaker, and the relationship of the classification to its goal is not so attenuated as to render the distinction arbitrary or irrational.” Id. at 11 , 112 S.Ct. 2326 (internal citations omitted).

Defendant here argues that the employees covered by the PERB decisions are not similarly situated to the non-unionized employees because the latter group of retirees are former members of unions that challenged the change in benefits and *1168 were covered by the PERB ruling directing the County to make them whole. ECF 54. Plaintiffs suggest this distinction does not matter, because frequently the non-unionized employees held the same jobs, but are now treated differently, and the County has applied “an across-the-board denial of the subsidy to both union and non-union retirees.” ECF No. 53 at 1.

In the Eleventh Circuit ease of Marshall v. Western Grain Co., Inc., 838 F.2d 1165 (11th Cir.1988), the plaintiffs were union members who were not given severance pay when they were laid off, even though other employees who did not have a collective bargaining agreement did receive severance pay. The union employees, all but one of whom were African American, brought a Title VII action, alleging racial discrimination. Id. at 1165-66 . The Eleventh Circuit said that plaintiffs had not stated a claim of discrimination under Title VII, recognizing that “because of their unique status in the workplace, bargaining unit employees are never similarly situated with non-bargaining unit employees. The unique treatment that employers give to bargaining unit members is, of course, reflected best by the collective bargaining agreement.” Id. at 1170 (footnote omitted; emphasis in original). The court in Marshall recognized that an employer may not modify the provisions of the collective bargaining agreement (CBA) concerning wages, hours and other conditions of employment without bargaining. Id. at 1170-71 . It concluded that

Id. at 1171 (emphasis in original); see also Davis v. Ineos ABS (USA) Corp., Civil Case No. 09-773 JGW, 2011 WL 1114409 , at *3-4 (S.D.Ohio Mar. 24, 2011) (noting that union employees are not similarly situated to non-union employees in Title VII cases because “an employer must often go through a complex process in order to discipline an employee covered by a collective bargaining agreement”). The Eleventh Circuit has applied Marshall when evaluating whether non-union employees are similarly situated to union employees as part of an equal protection challenge. Donnell v. Lee Cnty. Port Auth., 509 Fed.Appx. 903, 905-06 (11th Cir.2013) (unpublished).

Plaintiffs argue that Marshall is not persuasive, as the Eleventh Circuit distinguished it in National Labor Relations Board, v. United States Postal Service., 888 F.2d 1568 (11th Cir.1989). 11 In that case, the NLRB sought information about discipline imposed on supervisors who had engaged in gambling, but the Postal Service resisted, citing Marshall among other *1169 reasons. The court said that the information the NLRB requested had some bearing on whether the union employees were unjustly disciplined even though the supervisors had different responsibilities, as “the same rule prohibiting gambling activities is applicable to both unit employees and to supervisors.” Id. at 1571. Plaintiffs here argue the County has applied an across-the-board denial of the subsidy to both union and non-union employees alike, making this case more like National Labor Relations Board than Marshall . (ECF No. 53.) However, nothing in National Labor Relations Board implicated the employer’s reaction to and/or accommodation of a CBA. In contrast, in Marshall as in this case, the County has presented evidence that its actions were restricted by the considerations and limitations inherent in collective bargaining.

This court thus finds Marshall to have some persuasive force, as long as its pronouncement, that “bargaining unit employees are never similarly situated with non-bargaining unit employees,” is not read as a blanket statement that applies without respect to the facts of a given case. In California, under the Meyers-MiliasBrown Act (“MMBA”), the County has a duty to bargain with employees’ unions before changing wage or working conditions: “ ‘The duty to bargain requires the public agency to refrain from making unilateral changes in employees’ wages and working conditions until the employer and employee association have bargained to impasse....’” Coachella Valley, 35 Cal.4th 1072, 1083 , 29 Cal.Rptr.3d 234 , 112 P.3d 623 (quoting Santa Clara Cnty. Counsel Attorneys Ass’n v. Woodside, 7 Cal.4th 525, 537 , 28 Cal.Rptr.2d 617 , 869 P.2d 1142 (1994)). Plaintiffs have not pointed to a similar duty to bargain with non-union employees. And in this case, it was the County’s failure to bargain that led to the PERB action. The remedies available to union employees means they are not similarly situated to non-union employees.

While one putative sub-class in this case consists of unionized employees whose unions pursued the action before PERB, both equal protection claims as pled compare the employees whose subsidy was reinstated because of the PERB action to those who did not appear before PERB. The one subclass cannot claim they were denied their right to equal protection given the way the issue is framed in the complaint.

Even if the non-unionized employees were similarly situated, plaintiffs still have not rebutted the County’s showing that the disparate treatment had a rational basis. Under that highly deferential level of review, the County “has no obligation to produce evidence to sustain the rationality of a statutory classification,” because “[t]he burden is on the one attacking the legislative enactment to negative every conceivable basis that might support it.” Heller v. Doe, 509 U.S. 312, 320 , 113 S.Ct. 2637 , 125 L.Ed.2d 257 (1993). Here the County complied with the PERB order to make the unionized employees whole, which satisfies the rational basis test.

Plaintiffs argue generally that the distinction between union and non-union employees was not rational because PERB ordered the County to make all the employees affected by the change whole. ECF No. 48 at 23. This argument is puzzling, for it suggests, without any citation to authority, that the non-unionized employees were somehow in privity with the union members or that PERB had the authority to issue sweeping orders unconstrained by the unfair labor practice before it.

The California Legislature created PERB “to adjudicate unfair labor practice charges: ‘[t]he initial determination as to *1170 whether the charges of unfair practices are justified and, if so, what remedy is necessary to effectuate the purposes of this chapter, shall be a matter within the exclusive jurisdiction of the board.’ ” San Diego Mun. Emp. Ass’n v. Superior Court, 206 Cal.App.4th 1447, 1456 , 143 Cal.Rptr.3d 49 (2012) (quoting Cal. Gov’t Code § 3541.5) (emphasis omitted); see also 8 Cal.Code Regs. § 32615(a) (“A charge may be filed alleging that an unfair practice or practices have been committed.”). Nothing suggests that PERB has the authority to adjudicate questions unrelated to unfair labor practices before it or that a finding of an unfair labor practice can somehow be construed as a finding that the County had an implied contract to provide a vested health care subsidy to all its employees. This argument does not advance plaintiffs cause. Defendant is entitled to judgment on these claims.

IT IS THEREFORE ORDERED that defendant's motion for summary judgment (ECF No. 40) is GRANTED and this case is CLOSED.

. Subclass one consists of "[r]etirees who retired before June 1, 2007, and who were not represented by a union before the PERB who are currently receiving a maximum health insurance subsidy off-set of' $80.64 each month.” Compl., ECF No. 1 ¶ 8. Subclass two consists of "[r]etirees who were informed in 2007 that they would need to retire on or before May 31, 2007, in order to be eligible to receive the health insurance subsidy and who did retire prior to June 1, 2007, with the intent to remain eligible for the health insurance subsidy for the duration of their retirement who are now receiving a maximum medical insurance premium off-set for $80.64 each month.” Id. Subclass three consists of "[rjetirees who retired after May 31, 2007, who were not represented by a union before the PERB and who are currently receiving no health or dental insurance subsidy off-set as a result of the changes enacted by the Sacramento County Board of Supervisors.” Id. Subclass four consists of "[rjetirees who were represented by a union before the PERB who are receiving a maximum medical insurance subsidy of $244 each month with an additional $25 subsidy for dental insurance premiums plus 7% interest as a result of the PERB ruling.” Id.

Plaintiffs dispute this fact, noting that the inserts say that the subsidy is provided subject to annual review by the Board, "the understanding being that the amount of the subsidy might change depending upon the cost of the insurance premiums and the availability of funds for the subsidy.” ECF No. 48-1 ¶ 15. The court quotes directly from representative inserts, finding their language undisputed.

Apr. 10, 2013) (stating that any disputed fact that a party does not support with admissible evidence is insufficient to defeat summary judgment); FED. R. CIV. P. 56(c)(1)(A) (stating that a party asserting that a fact is disputed must support the assertion by citing to particular parts of material in the record).

. As the County does not argue that there cannot be an implied vested right to health care, this court does not discuss the third part of the California Supreme Court's analysis, answering whether any such implied vested contractual rights can include health benefits.

. A vested right is one that is "already possessed or legitimately acquired,” generally after a person "has rendered services” in reliance on another's representations. Contractual rights arise from the parties’ bargain or are implied by their conduct. Hanford Exec. Mgmt. Emp. Ass’n., 2012 WL 603222 , at *7. "In the context of public employment, vested contractual rights are the exception, not the rule.” Id. at *8.

. The Circuit in the decision cited here addresses only two of the REAOC cases; the decision refers to the Supreme Court decision identified in this order as REAOC III as REAOC II, and to the Circuit’s 2010 decision identified here as REAOC II, as REAOC I.

. The court disregards Robert T. Smith’s statement that employees detrimentally relied on the idea that the subsidy was vested and so did not transfer to jobs with better retirement health benefits. To the extent the statement is within Mr. Smith’s personal knowledge, it is based on hearsay.

. At argument plaintiffs’ counsel asserted that every time the county approved an MOU including the subsidy, this was an implied understanding of the contractual obligation. Plaintiffs have presented no evidence of any MOUs the County adopted, with or without the subsidy. Plaintiffs also claimed that the yearly Resolutions adopting the retirees’ subsidy were probably simply boilerplate, adopted with little thought but have again provided no evidence supporting this claim.

. Plaintiffs also cite to two California federal district court cases they say suggest Marshall is unpersuasive within the Ninth Circuit. See ECF 53 at 2. The court has reviewed both cases, which declined to follow certain other cases relied on in Marshall ; those courts’ determinations, however, were based on factual distinctions evident in determining whether or not to certify a class and do not signal that Marshall runs afoul of any established Ninth Circuit precedent. See California State Employees’ Ass’n v. California, 1985 U.S. Dist. LEXIS 15974 , 1985 WL 397 (N.D.Cal.1985); Walthall v. Blue Shield of California, 1977 U.S. Dist. LEXIS 13773 , 1977 WL 15423 (N.D.Cal.1977).
