ORDER (1) DENYING MOTION FOR REMAND OR DISMISSAL, (2) GRANTING REQUESTS FOR JUDICIAL NOTICE AND (3) DENYING MOTION FOR RULE 19(a) JOINDER
ALSUP, District Judge.

INTRODUCTION
Asserting four state-law claims, plaintiff County of Santa Clara moves for joinder of additional defendants and, based on such joinder, for remand to state court for lack of subject-matter jurisdiction. As an alternative to remand, it moves for dismissal due to lack of jurisdiction. Santa Clara and the defendants, all pharmaceutical manufacturers, separately have requested judicial notice of certain facts. The requests for judicial notice are unopposed and are GRANTED. The motion for remand or dismissal is DENIED; this Court has federal-question subject-matter jurisdiction. *1024 The Rule 19(a) motion for joinder is DENIED.

STATEMENT
Defendants make pharmaceuticals, including common medicines such as Tums, Excederin and the antibiotic, Zithromax (Compl.śś 19-21).[1] They provide these medications to distributors who sell them to public hospitals and health-care clinics (Br.2). As required by state law, Santa Clara County pays the cost of drugs given to many indigent and other patients at such medical facilities, including the Santa Clara Valley Medical Center. See Cal. Welf. & Inst.Code § 17000. In 2004, the county spent more than $30 million on prescription and over-the-counter medications given to outpatients at such facilities (Compl.śś 1, 3, 7).
The federal government sets maximum prices at which such medications can be sold to public health-care institutions for use in outpatient treatment (Com pl.śś 26-27). 42 U.S.C. 256b. Santa Clara sued defendants in Alameda County Superior Court, claiming they had bled the county's finances with overcharges for these medicines. Santa Clara asserted four claims on behalf of itself and similarly afflicted California counties: violations of the state's unfair-competition law and false-claims act, for an accounting that would reflect the amount of overcharges and for unjust enrichment (Compl.śś 68-87). Defendants removed the action here claiming diversity and federal-question jurisdiction (Notice of Removal of Action 1). Santa Clara made a timely motion for remand.

ANALYSIS
1. JUDICIAL NOTICE.
Santa Clara requested judicial notice of a publication in the Federal Register describing federal price limitations on prescription medications (Pl.'s Req. 1). Defendants requested judicial notice of six different matters: a description of the price-control regime on a Department of Health and Human Services web site; a report by the same department; the Pharmaceutical Pricing Agreement (the standard drug-pricing contract between the government and drug makers participating in the price-control program); complaints filed in two federal lawsuits; and a list of California cities by the League of California Cities (Defs.' Req. 1-3).
Under Federal Rule of Evidence 201, a court must take judicial notice of adjudicative facts if a party requests it to, if it supplies the necessary information to decide the request and if the facts are "not subject to reasonable dispute" because they are "capable of accurate and ready determination by resort to sources whose accuracy cannot reasonably be questioned."
The time has passed for parties to object to the requests. They have not done so. Both sides have met their Rule 201 requirements. This order takes notice of the requested matters.
2. FEDERAL-QUESTION JURISDICTION.
District courts have jurisdiction over civil cases arising under the Constitution, laws and treaties of the United States. 28 U.S.C. 1331. When such a case is filed in state court, defendants may remove it to federal court. 28 U.S.C. 1441(b). Federal courts must construe the removal statute strictly. Shamrock Oil & Gas Corp. v. Sheets, 313 U.S. 100, 108-09, 61 S.Ct. 868, 85 L.Ed. 1214 (1941).
*1025 Federal-question jurisdiction arises most obviously for rights of action conferred by a federal statute or constitutional provision. Section 1331 also confers jurisdiction when an issue of federal law undergirds a claim otherwise based in state law. Such a claim, however, may only be removed to federal court if it meets certain conditions: (1) it must raise a stated federal legal issue, (2) determination of the federal issue must be necessary to resolution of the claim, (3) the federal issue must be actually disputed, (4) the federal issue must be substantial, and (5) the federal court must be able to entertain the claim "without disturbing any congressionally approved balance of federal and state judicial responsibilities." Grable & Sons Metal Prods., Inc. v. Darue Eng'g & Mfg., ___ U.S. ___, 125 S.Ct. 2363, 2366-68, 162 L.Ed.2d 257 (2005). If only one of several state claims satisfies the requirements for removal on federal-question grounds, then any other purely state claims in the same complaint may also be determined by the federal court under its supplemental jurisdiction. 28 U.S.C. 1441(c). This order now analyzes whether the Grable and Sons requirements are met here.
The instant case raises two stated federal legal issues: one contractual and one statutory. All the claims asserted by Santa Clara explicitly involve allegations that it was victimized by drug prices in excess of those allowed under a federal statute, 42 U.S.C. 256b, and under the Pharmaceutical Pricing Agreement, a contract between the federal government and the manufacturers (see Compl. śś 2, 7, 34; Defs.' Req. for Judicial Notice, Exh. B).[2] The contract, by its own terms, must be "construed in accordance with Federal common law" (Pharmaceutical Pricing Agreement at § VII(g), Defs.' Req. for Judicial Notice, Exh. B). Both violations of the federal statute and breaches of the federal contract raise obviously federal issues. See Boyle v. United Techs. Corp., 487 U.S. 500, 504, 108 S.Ct. 2510, 101 L.Ed.2d 442 (1988) ("[O]bligations to and rights of the United States under its contracts are governed exclusively by federal law."); Illinois v. City of Milwaukee, Wis., 406 U.S. 91, 100, 92 S.Ct. 1385, 31 L.Ed.2d 712 (1972) ("[Section] 1331 jurisdiction will support claims founded upon federal common law as well as those of a statutory origin.").
Contrary to Santa Clara's assertions at the hearing, determination of at least one of the stated federal issues is necessary. The alleged misconduct undergirding Santa Clara's claims distills to this: defendants purported to sell drugs in accordance with the federal-government's price prescriptions yet actually charged more. This conduct injured Santa Clara because it was obligated for those overcharges under state law. See Cal. Welf. & Inst.Code § 17000 (counties responsible for indigent medical care). For this case to be resolved on its merits, at least one of the federal issues embedded in the complaint must be addressed. There is simply no other way.
The necessity of determining the federal issues was hotly disputed by the parties in the briefs and at the hearing. This order therefore carefully examines each claim, demonstrating why it requires determination of at least one federal issue. Again, even if only one of the claims falls under *1026 federal-question jurisdiction, all may be heard here. See 28 U.S.C. 1441(c).
First, Santa Clara claims that it is entitled to an accounting. It wants this remedy so it may determine whether it paid more than allowed under the federal price-control statute and the Pharmaceutical Pricing Agreement (Compl.ś 74). An essential element of a claim for accounting is that there is a balance due from the defendant that can only be ascertained by an accounting. St. James Church of Christ Holiness v.Super. Ct. in and for L.A. County, 135 Cal.App.2d 352, 359, 287 P.2d 387 (1955). The only way in which Santa Clara claims that a balance is due is by asserting that defendants charged in excess of the amount required by federal statute and contract. The only methods to determine the proper price are to construe or interpret the relevant federal statutes and contract. The accounting claim therefore requires determination of a federal issue.
Second, Santa Clara claims that defendants engaged in "an unfair, unlawful, and deceptive scheme to collect inflated charges that exceed the . . . ceiling price . . . and unlawfully and fraudulently charged . . . substantially more than the . . . ceiling price." Plaintiff claims this violated the state unfair-competition law (Compl.ś 77). See Cal. Bus. & Prof.Code § 17200. An unfair-competition claim is made out if the alleged conduct was either unfair, fraudulent or unlawful. An allegation that defendants violated Section 17200 by unlaw ful conduct obviously requires determination of whether they violated the federal price-control statute or contract. An allegation that they acted fraudulently or unfairly also requires determination of a federal issue because it boils down to claims that defendants said they were providing the federally mandated discounts but did not (see Compl. śś 76-79).
Santa Clara asserts that its allegations of unfair and fraudulent conduct provide theories of liability independent of any federal-law issue (Br. 13-14; Reply 4). It claims that defendants acted unfairly and fraudulently when they allegedly "misrepresented and failed to disclose . . . the true facts regarding their prices" (Reply 4). Liability under the unfair and fraudulent prongs of Section 17200 does not always require violation of a separate law. Cel-Tech Communications, Inc. v. L.A. Cellular Tel. Co., 20 Cal.4th 163, 180, 83 Cal.Rptr.2d 548, 973 P.2d 527 (1999). If, for example, Santa Clara had alleged that defendants were not required to provide the discounts yet falsely claimed to be providing them nevertheless, its claim of unfair or fraudulent acts would not have turned on a federal issue. Santa Clara, however, did not assert any such thing. The only reasons it has given for believing that defendants behaved unfairly or fraudulently were that they failed to give required discounts. The Section 17200 claim therefore requires determination of whether defendants violated any federal statutory or federal contractual obligation to provide the discounts and, if they did, by how much they overcharged.
Third, Santa Clara asserted a violation of the state False Claims Act. See Cal. Gov't Code § 12651. The county alleges that defendants did one or more of the following: (1) falsely billed in excess of the amount owed for medications, (2) made false records to support such claims, (3) falsely sought to avoid obligations to pay money back to Santa Clara or (4) benefited from inadvertent false billings for drug payments, discovered their falsity and yet failed to rectify the errors (Compl.ś 82). In theory, perhaps, such a claim could be made out independent of any federal issue. For instance, Santa Clara could have alleged that defendants were not required to provide the discounts yet nevertheless *1027 falsely claimed to have done so. The county, however, has not made any such accusation. In fact, it repeatedly stated that discounts were required. The only basis on which it claims the billings were false are that the manufacturers were required by federal law and contract to provide lower prices. If there was a false billing that did not turn on the federal price limits, Santa Clara may seek leave to amend its claim. Until it does so, there is no way around the federal issues.
Fourth, Santa Clara alleges unjust enrichment. Unjust enrichment requires that the defendant improperly obtained a benefit. Recovery consists of restitution of the ill-gotten gains to the party who rightfully should have them. See Kossian v. Am. Nat'l Ins. Co., 254 Cal.App.2d 647, 649-51, 62 Cal.Rptr. 225 (1967); see also 1 B.E. Witkin, Summary of Cal. Law § 1013 (10th ed.2005). In alleging unjust enrichment, Santa Clara claims defendants "agreed to supply drugs . . . at prices no greater than the . . . ceiling price . . . [yet] failed and refused to comply with that agreement[] and[,] as a result [,] defendants have retained monies to which they are not entitled" (Compl.ś 85). Whether they failed to comply with the agreement requires a determination of (1) the price limits and (2) whether defendants had any federal statutory or contractual obligation to comply with them. There is simply no way to ignore federal law.
The stated federal issues are disputed in the instant case. Defendants claim to dispute plaintiff's interpretations of "average manufacturer price" and "best price," terms used to determine the proper drug prices (Opp. 5, see Pharmaceutical Pricing Agreement I(a)-(b) (defining both terms), Defs.' Req. for Judicial Notice, Exh. B). See also 42 U.S.C. 1396r-8(k)(1) (definition of average manufacturer price); 42 U.S.C. 1396r-8(c)(1)(C)(i)-(ii) (definition of best price). Defendants also claim that they disagree with Santa Clara over the proper interpretation of the statute dictating how to calculate maximum prices, 42 U.S.C. 1396r-8.
The pricing issues in the instant case are substantial questions of federal law. There are two ways to judge the substantiality of a federal issue. First, if it has legal substance and some prospect of success, it survives. Hagans v. Lavine, 415 U.S. 528, 536-38, 94 S.Ct. 1372, 39 L.Ed.2d 577 (1974) (holding that constitutional claims are insubstantial "only if its unsoundness so clearly results from the previous decisions of this court as to foreclose the subject and leave no room for the inference that the questions sought to be raised can be the subject of controversy"). The Hagans rule also applies to purely statutory cases. See Mackey v. Pioneer Nat'l Bank, 867 F.2d 520, 523 (9th Cir.1989) (addressing the 1986 Comprehensive Omnibus Budget Reconciliation Act).
Courts have fashioned an alternative way to evaluate substantiality: the importance of the federal issue. Under this approach, the following issues have been found to be substantial: those that directly affect the functioning of the federal government, those in an area reserved for exclusive federal jurisdiction, and those that impact a complex federal regulatory scheme. Grable & Sons, 125 S.Ct. at 2368 (holding that construction of IRS notice requirements were substantial because they would have a direct impact on tax collection); Hunter Douglas, Inc. v. Harmonic Design, Inc., 153 F.3d 1318, 1329 (Fed.Cir.1998) (holding that the validity and enforceability of patents, under exclusive federal jurisdiction, are substantial enough to warrant federal-question jurisdiction over a state-law tort claim); Broder v. Cablevision Systems Corp., 418 F.3d 187, 195 (2d Cir.2005) (holding that interpretation *1028 of complex federal cable-television-rate statutes was substantial).
This order next examines the merit of the arguments in the instant case that are based on federal law. Then, it determines the likely impact of resolving the federal issues.
There is no decision directly deciding whether defendants' statutory-construction and contractual-interpretation arguments are substantial. This order finds, however, that defendants raise sufficiently plausible issues to withstand remand. In fact, a substantial amount of judicial ink already has been spilled over the meaning of a term that may be significant in the instant case. See Pharm. Research & Mfrs. of Am. v. Thompson, 251 F.3d 219, 224-26 (D.C.Cir.2001) (addressing meaning of "payment" in Medicaid statute). The Medicaid statute considered by the District of Columbia Circuit and the Medicaid statute now before this court apparently use "payment" in the same way. The definition of this term could be significant in the instant case because the only drugs that are covered by the discount program are those "purchased by the [health-care provider] for which payment is made by the State under the State plan for medical assistance under [the Medicaid statute]." 42 U.S.C. 256b(a)(3) (emphasis added). If a drug is not one "for which payment is made by the State" then it presumably is not subject to the price-control statute. Whether or not a drug used in Santa Clara's public health-care facilities is subject to the price controls could determine both liability and damages. Construction of the statute is therefore a substantial issue. Another heavily litigated federal case makes clear that there are significant disputes over how to determine the maximum price. See, generally, In re Pharm. Indus. Average Wholesale Price Litig., 230 F.R.D. 61 (D.Mass.2005).
Interpreting the federal statute and contract at issue here may significantly affect federal interests. Determination of the federal issues in this case could heal or injure the complex regulatory scheme of distributing outpatient medications to the poor and other disadvantaged people. Although the instant case currently is confined to the claims of just one county, it is a putative statewide class action and the federal issues have the potential to affect many people: approximately 12,000 healthcare providers participated in the price-control program in 2003, spending $3.4 billion for outpatient drugs (Dep't of Health and Human Services, Office of Inspector Gen., Deficiencies in the Oversight of the 340B Drug Pricing Program at 1 (Oct.2005), Defs.' Req. for Judicial Notice, Exh. C).
Santa Clara claims the issues are insubstantial. It argues that, if it wins the instant lawsuit, Medicaid reimbursements would not change. This argument is not lethal to defendants' removal. The important federal interest in price controls involves much more than the administration and amount of Medicaid reimbursements. They involve the broader issue of who should pay for indigent medical care in a nation hobbled by the lowest rate of health insurance coverage in the Western world. Santa Clara urged this Court to adapt a ruling by the District Court of Minnesota, claiming the decision bolstered its argument that the issues are insubstantial (Reply 7). See Minnesota v. Pharmacia Corp., No. 05-1394, 2005 WL 2739297 at *4 (D.Minn. Oct. 24, 2005). Santa Clara mistakenly cites the case for the proposition that the Medicare issues in that case were insubstantial (Reply 7). In fact, the district court in the portion of Pharmacia quoted by Santa Clara was addressing the proper "balance of federal and state judicial responsibilities." See Pharmacia, 2005 WL 2739297 at *4.
*1029 The substantiality of the federal issues in this case is driven home by conflict within the federal government itself over how to calculate the ceiling price. These calculations evidently involve more than mechanical and undisputable interpretations of federal law (see Deficiencies in the Oversight of the 340B Drug Pricing Program at ii ("[O]versight of the program is . . . hindered by the lack of detailed, written procedures for calculating 340B ceiling prices. Consequently, the 340B ceiling prices calculated by [the Centers for Medicare & Medicaid Services] . . . yielded incorrect ceiling prices."), Defs.' Req. for Judicial Notice, Exh. C).
The final sub-issue relevant to federal-question jurisdiction is whether hearing this lawsuit would disturb "any congressionally approved balance of federal and state judicial responsibilities." See Grable & Sons, at 2368. This Court might pause before finding federal-question jurisdiction here if unfair-competition cases previously had been heard only in state court. Such Section 17200 cases, however, are already endemic in federal court, as Santa Clara effectively concedes (Reply 10 ("U[nfair-competition law] claims are often predicated on federal law.")). See, e.g., Lockyer v. Dynegy, Inc., 375 F.3d 831, 841 (9th Cir.2004) (unfair-competition claim predicated on federal issues subject to exclusive federal jurisdiction; holding unaffected by subsequent amendment at 387 F.3d 966, 968 (9th Cir.2004)); Nat'l Credit Reporting Ass'n v. Experian Info. Solutions, Inc., No. C 04-01661 WHA, 2004 WL 1888769, at *3, 2004 U.S. Dist. LEXIS 17303 at *10 (N.D.Cal. July 21, 2004) (denying remand of Section 17200 claim).
Santa Clara nevertheless argues that "shifting" cases to federal court premised on pharmaceutical companies' overcharges would disrupt a the proper federal-state balance (Reply 10). See Grable & Sons, 125 S.Ct. at 2368. There is, however, no congressionally approved balance of judicial responsibilities in this arena. During the approximately 13 years that the price controls have been in place, both state and federal courts have heard cases related to the statutes directly governing them. See, e.g., Univ. Med. Ctr. of S. Nev. v. Shalala, 173 F.3d 438 (D.C.Cir.1999) (on whether plaintiff had standing to sue over its eligibility for discounts); Pharmacia Corp., 2005 WL 2739297 at *4 (motion to remand granted in dispute about overcharges); Wisconsin v. Abbott Labs., 390 F.Supp.2d 815, 825 (W.D.Wis.2005) (same); Montana v. Abbot Labs., 266 F.Supp.2d 250, 263 (D.Mass.2003) (remanding two overcharge cases and retaining federal jurisdiction over two others); and, generally, In re Pharm. Indus. Average Wholesale Price Litig., 230 F.R.D. 61 (heard under federal jurisdiction).[3]
Santa Clara argued in its briefs that Merrell Dow Pharmaceuticals, Inc. v. Thompson, 478 U.S. 804, 817, 106 S.Ct. 3229, 92 L.Ed.2d 650 (1986), requires a different result here. At hearing, counsel for Santa Clara also cited three of the decisions named immediately above: Montana v. Abbot Laboratories (a later decision in the Montana case), and Wisconsin v. Abbott Laboratories.
In Merrell Dow, the Supreme Court held that there was no federal jurisdiction over state tort claims merely because they borrowed a duty of care from a federal statute. The federal statute at issue in Merrell Dow conferred no independent right of action and had not preempted *1030 state law. Counsel here notes that, as in Merrell Dow, there is no independent right of action under the drug price-control statute and that it did not preempt state regulation. Merrell Dow did not, however, bar federal jurisdiction over state claims in the absence of preemption or a federal cause of action. It merely held that there is no "welcome mat" inviting federal jurisdiction for such cases. Grable & Sons, 125 S.Ct. at 2370. What barred federal jurisdiction in Merrell Dow was that it would have attracted a "horde of original filings and removal cases" to federal court. Such a stampede would have bruised federal comity. Ibid. The Montana decision to remand Minnesota's case to state court was issued before Grable and Sons and rested on the once-common interpretation of Merrell Dow that it barred federal jurisdiction over state-law claims that used, as a standard, a federal law for which Congress had not provided a right of action. Montana, 266 F.Supp.2d at 257. The Grable and Sons Court held that interpretation incorrect. For this reason, the Montana court's ruling is not persuasive.
Counsel for Santa Clara also argued that Pharmacia and Wisconsin persuasively found that federalizing a case such as this one would upset the proper balance of judicial responsibilities.[4] This order disagrees. The Wisconsin court's first rationale was that the state had as much of an interest in Medicaid drug prices as did the federal government. This analysis confounds two aspects of the Grable and Sons analysis: judicial balance and the substantiality of the federal interest. Whether the federal interest is strong is a question for the substantiality analysis, not the balance analysis. The instant case is also distinct: it involves a federal contract whereas none was at issue in Wisconsin. The instant case therefore has a higher quotient of federal interest. The Wisconsin court's second rationale was that allowing federal jurisdiction would disrupt the balance of judicial responsibilities to a degree more akin to that feared in Merrell Dow than that feared in Grable and Sons. Like Merrell Dow, the instant case uses a federal standard to measure violation of state-law statutory and common law. But, unlike Merrell Dow, the instant cases may involve interpretation of a federal contract under federal common law, the type of task that already falls to federal courts. The Wisconsin court also reasoned that, although many drug-pricing cases already were in federal court, this did not reflect the proper balance because those removals took place before Grable and Sons. This proves little because, if Grable and Sons actually changed the law to deprive those courts of jurisdiction, they could have remanded them to state court sua sponte. See, e.g., Csibi v. Fustos, 670 F.2d 134, 136 n. 3 (9th Cir.1982) ("[L]ack of subject matter jurisdiction can be raised by a court's own motion at any time. . . . [I]t is the duty of the federal courts to assure themselves that their jurisdiction is not being exceeded."); White v. Gittens, 121 F.3d 803, 806 (1st Cir.1997) ("[A] court has an obligation to inquire sua sponte into its subject matter jurisdiction, and to proceed no further if such jurisdiction is wanting."). They have not, so far as counsel have identified, done so. This order also disagrees with the Wisconsin court's suggestion that moving all state cases involving drug pricing to federal court would work a disruption akin to that feared by the Merrell Dow Court. See Wisconsin, 390 F.Supp.2d at 823-24. In Merrell Dow, the plaintiffs claimed negligence, breach of warranty, strict liability, fraud and gross negligence. 478 U.S. at 805, *1031 106 S.Ct. 3229. For some of these claims, violation of a statute often proves both duty and breach. Allowing such a slim connection to federal law to create Section 1331 jurisdiction would have moved many garden-variety tort claims from state to federal court. The same can hardly be said in the instant case. Violation of federal law will rarely be a presumptively conclusive element of claims for accounting, unjust enrichment, false claims or unfair competition. The instant drug-pricing case probably falls somewhere between Grable and Sons, on the one hand, and Merrell Dow, on the other.
As a final matter, this Court notes that the federal-question decisions in Wisconsin and Pharmacia were not essential in granting the motions for remand. In each case, removal had been procedurally defective and provided an independent and adequate reason to remand to state court. Wisconsin, 390 F.Supp.2d at 824; Pharmacia, 2005 WL 2739297 at *2.
There is no reason to believe that allowing federal jurisdiction over cases such as the instant one would tip the balance of federal-state judicial responsibilities. As noted above, such cases already have been heard in both federal and state fora. Furthermore, complaints such as the instant one tend to be class actions, reducing any increase in the number of additional cases such jurisdiction would put into federal courts.
Finally, this order's determination that there is federal jurisdiction comports with the requirement that the removal statute be construed strictly. Shamrock Oil & Gas, 313 U.S. at 108-09, 61 S.Ct. 868; see Duncan v. Stuetzle, 76 F.3d 1480, 1484-91 (9th Cir.1996) (analysis identical to this order's consideration of the necessity of the federal issue).
In summary, this order diagnoses the instant action as terminally federal in nature. The district court has federal-question jurisdiction over the complaint.
3. MOTION FOR JOINDER
Santa Clara moves for necessary joinder of three medical distributors under Federal Rule of Civil Procedure 19(a).
It seems obvious that this Rule 19(a) argument is a tactic in Santa Clara's larger remand strategy. By deeming the wholesalers part of this case, in a sort of nunc pro tunc way, the county hopes to defeat the diversity basis for removal (see Br. 6 "[T]he propriety of the Court's jurisdiction based upon diversity of citizenship is ordinarily determined at the time the Complaint is filed, unless the joinder of a party would defeat diversity jurisdiction, in which event the action must be remanded or dismissed."). That strategy would fail, in all events, for the reason that federal-question removal jurisdiction is sufficient without regard to diversity. A separate stand-alone motion for joinder has been made, however. This order therefore must address it.
The heart of Rule 19(a) is a disjunctive analysis. If either of two prongs is satisfied, joinder is mandatory. First, if complete relief cannot be had between the parties, joinder is required. Second, the court must join the non-party if it has a legally protected interest in the subject of the action and disposition in its absence would either (1) impede or destroy its ability to protect that interest or (2) leave the parties subject to a "substantial risk" of multiple or inconsistent obligations. FRCP 19(a).
Santa Clara seeks to join McKesson Corp., AmerisourceBergen Corp. and Cardinal Health, Inc. These wholesalers contract with the counties to provide defendants' medications. They allegedly failed to pass on the requisite discounts (Br.2, 9).
*1032 Joinder of the distributors is not required to accord complete relief among Santa Clara and defendants. Santa Clara claims that it needs the Court to order the distributors to sell pharmaceuticals at discounted prices (Br.11-12). This Court's inability to issue such orders absent joinder does not preclude complete relief among the parties already present. It only prevents complete relief as between Santa Clara and the wholesale distributors. This argument therefore collapses.
Santa Clara also claims that complete relief would require a constructive trust to be imposed upon the distributors so that they would not dissipate the overcharges Santa Clara paid to them. Even assuming that a constructive trust is a proper remedy here, imposition of one would not be necessary. Defendants have more than enough assets to satisfy any judgment in this case.
Santa Clara also claimed at the hearing that full relief is impossible without joinder because the distributors' non-party status would hamper its discovery efforts (see also Reply 15). Santa Clara did not back up this claim with any example of the discovery that (1) is so important that without it complete relief cannot be afforded and (2) the distributors would be more likely to give up if they were joined. This argument borders on the frivolous.
Plaintiff argues that its request for an accounting cannot be accomplished without joinder (Br.8). An accounting is an equitable remedy by which a party opens its books so that the other side may calculate amounts owed. In the instant case, the amount owed, if any, to Santa Clara by defendants can be determined in two steps. First, calculate the proper price of the drugs using defendants' sales records and price calculations prescribed by federal statute and contract. Second, determine for which purchases the health-care providers sought reimbursement. All of this information is held either by Santa Clara, its health-care providers or defendants. There is no need to pry into distributors' books outside of normal civil discovery. Santa Clara's accounting-remedy argument therefore does not justify joinder under Rule 19.
The county additionally claims that, without joinder, it would have no way to determine whether defendants met their purported obligation to "ensure that distributors pass along the discounts" (Br.8). Why not? Santa Clara made no persuasive effort to explain. Again, normal civil discovery seems likely to solve this problem. Furthermore, this alleged problem could not present a difficulty in according relief. It merely would make it more difficult for Santa Clara to prove liability. This argument is therefore rejected.
Santa Clara also argues that joinder is necessary to protect the distributors because of the scope of discovery to which they will be subjected: "[b]ecause the distributors will have the burden of producing all of the relevant evidence [,] they must also have the ability to defend themselves afforded to litigants" (Reply 14). It is silly to suggest that the distributors will have the burden of producing "all of the relevant evidence." Furthermore, Santa Clara can point to no way in which these discovery issues would impact the distributors' interests implicit in this litigation, namely their contracts with Santa Clara and defendants. This argument fails.
Santa Clara additionally claimed at the hearing and in its briefs that, if the distributors are not joined, disposition of the action will impair their ability to protect the interests they have in contracts with Santa Clara due to the effects of collateral estoppel (Br.10-11). These arguments were dead on arrival.
The collateral estoppel doctrine stands for the principle that when a final judgment has determined an ultimate issue *1033 of fact, it is conclusive in any subsequent lawsuit based on different claims but involving a party to the prior litigation. Ashe v. Swenson, 397 U.S. 436, 443, 90 S.Ct. 1189, 25 L.Ed.2d 469 (1970); Montana v. United States, 440 U.S. 147, 153, 99 S.Ct. 970, 59 L.Ed.2d 210 (1979). Even some entities that were not party to the original litigation may be bound by it. This generally applies, however, only when they effectively were represented in the first litigation and had interests closely aligned with the actual party. See, e.g., Sea-Land Servs., Inc. v. Gaudet, 414 U.S. 573, 593-94, 94 S.Ct. 806, 39 L.Ed.2d 9 (1974) ("[B]eneficiaries are bound by the judgment with respect to the interest which was the subject of the fiduciary relationship.") (internal citation omitted).
Santa Clara has presented no facts to suggest that the instant case could have any collateral-estoppel effect on the distributors. The distributors do not have a representative and closely aligned relationship with defendants in the context of this litigation. Their interests actually might be antagonistic to one another, given the possibility that each might blame the other for any alleged overcharges. Furthermore, Santa Clara wants it both ways: in one sentence, it asserts that the distributors would be bound by preclusion and â   in the very next sentence â   it asserts that they must be protected because defendants would not properly represent their interests (Br.11). Like a fatal drug interaction, the combination of these arguments mortally wounds this motion for joinder.[5]
Santa Clara pretends to worry about defendants, asserting that they may be subject to a substantial risk of inconsistent judgments if the distributors must be sued in a separate lawsuit. It does not specify, however, how any judgments would be inconsistent. Presumably, the judgment in any action solely against distributors would be binding only upon the distributors and would not require any remedy necessitating action on the part of the manufacturers.
Plaintiff also argues that, if it is not granted its Rule 19 motion for joinder, it will be "required" to file a second action against the distributors. Not so. Rule 19 is not the only procedure to get distributors into the case. Rule 20 is another way to do so. Santa Clara is free to file a motion under the more permissive standards of Rule 20. Santa Clara is always free to bring a normal motion to amend. The accompanying case management order will invite Santa Clara to do so.
Santa Clara has not made a sufficient showing that joinder is necessary to force distributors into this lawsuit. The Rule 19(a) motion is therefore denied.

CONCLUSION
This order holds that the instant case is removable because there is federal-question jurisdiction. It therefore has no need to address diversity-jurisdiction issues raised by both sides. The motions for remand and, in the alternative, for dismissal are DENIED for the reasons stated above. Joinder is unnecessary so the Rule 19(a) motion also is DENIED.
IT IS SO ORDERED.
NOTES
[1]  For purposes of this order, all factual allegations in the complaint are deemed true. Defendants have not in any way responded to those allegations; a formal answer is not yet required.
[2]  Santa Clara states that its claim for violation of the California False Claims Act does not mention any violations of federal law (Reply 4, n. 5). This is misleading. The claim incorporates all 80 of the preceding paragraphs of the complaint "as through set forth in full herein" (Comp.ś 81). Those 80 paragraphs provide a rash of allegations that defendants trampled federal laws.
[3]  Although the decision from the District Court of Massachusetts is captioned with the defendant name Abbot Laboratories, the corporation is actually named Abbott Laboratories (with two t's), after its home base in Abbott, Illinois. The decision of the District Court of Wisconsin is correctly captioned.
[4]  Pharmacia quoted Wisconsin but added no new analysis. See 2005 WL 2739297 at *4. All references to the analysis of Wisconsin apply equally to Pharmacia.
[5]  Because there is no possibility that collateral estoppel would prevent the distributors from fully litigating any separate disputes with Santa Clara, its reliance upon Takeda v. Northwestern National Life Insurance Co., 765 F.2d 815 (9th Cir.1985), and Aguilar v. Los Angeles County, 751 F.2d 1089 (9th Cir.1985) is misplaced. See Takeda 765 F.2d at 821 (premising joinder of a party on the possibility that it might be collaterally estopped from litigating the same issues in future litigation) and Aguilar, 751 F.2d at 1092-94 (same).
