*850In the underlying action, appellant Paula Boyd asserted claims against respondent David Freeman predicated on allegations of wrongful foreclosure. The trial court sustained Freeman's demurrer to Boyd's first amended complaint without leave to amend, reasoning that the doctrine of res judicata barred her claims, in view of a judgment in favor of Freeman and against Boyd in a prior action. We conclude that the doctrine did not foreclose Boyd's claims because the prior judgment was not on the merits. We therefore reverse and remand for further proceedings.
*851RELEVANT FACTUAL AND PROCEDURAL BACKGROUND
In 2005, Boyd executed a promissory note in favor of attorney Freeman secured by a deed of trust for a property in Glendale. Later, Freeman initiated foreclosure proceedings that culminated in a July 16, 2012 foreclosure sale, at which Freeman became owner of the Glendale property.
In June 2012, while the foreclosure proceedings were pending, Boyd initiated her prior action against attorney Freeman (L.A. Super. Ct. Case No. BC486054). Her original complaint asserted claims for legal malpractice, breach of contract, breach of fiduciary duty, fraud, and declaratory relief, predicated on allegations that after Boyd hired Freeman to represent her in a matter, he made a "usurious" loan to her secured by the Glendale property. According to the complaint, in 2007, after Freeman attempted to arrange for a foreclosure sale of the property, Boyd and Freeman entered into a settlement agreement. The complaint asserted that Boyd's claims were for "violations that ... continued to occur after the settlement," alleging that Freeman "continued to use his legal status and his usurious loan terms to try to take the property illegally and wrongfully from [Boyd]." Although the complaint contained no claim for unlawful foreclosure in connection with the then-pending foreclosure, it alleged that Freeman had violated Civil Code section 2924f, which is a provision of the statutory scheme regulating nonjudicial foreclosure sales ( Civ. Code, § 2924 et seq. ).1
On July 16, 2012, shortly before the foreclosure sale, Boyd submitted an ex parte application for a temporary restraining *168order to enjoin the foreclosure sale. The application asserted that the notice of default misstated the amount due on the note, in contravention of Civil Code section 2924, subdivision (b)(1). The trial court denied the application.
Freeman demurred to the complaint, contending that Boyd's claims were time-barred under the applicable statutes of limitations. In addition, Freeman argued that the claims failed because the complaint's allegations regarding the 2007 settlement, viewed along with the note and trust deed, demonstrated *852the nonusurious nature of the loan. The trial court sustained the demurrer, but afforded Boyd leave to amend her claims, with the exception of her request for declaratory relief.
In March 2013, Boyd filed her first amended complaint. The complaint asserted a claim for breach of fiduciary duty predicated on allegations that Freeman had breached his professional obligations as an attorney in making the secured loan to Boyd, a claim for breach of fiduciary duty predicated on allegations that the loan was usurious, and a claim for restitution under the unfair competition law (UCL; Bus. & Prof. Code, § 17200 et seq. ) predicated on violations of the California Consumers Legal Remedies Act (CLRA; Civ. Code, § 1750 et seq. ) and Freeman's other alleged misconduct.2 The restitution claim sought recovery of the Glendale property, alleging, inter alia, that Freeman's misconduct resulted "in claims of foreclosure rights not in compliance with California law," as well as "a purportedly lawful but in fact void [t]rustee's sale ...."
Freeman demurred to the first amended complaint on the grounds that its claims were untimely under the applicable statutes of limitations, and were otherwise legally untenable. The trial court sustained the demurrer to the first amended complaint without leave to amend, concluding that it stated no viable claims. In October 2013, the court entered an order dismissing the prior action, from which Boyd noticed an appeal.
In an unpublished opinion ( Boyd v. Freeman (May 19, 2015, B253500) 2015 WL 2393991, 2015 Cal.App.Unpub. LEXIS 3449 ), we affirmed the order of dismissal, agreeing with the trial court that the claims in the first amended complaint were time-barred insofar as they relied on a breach of fiduciary duty, and that the UCL claim failed insofar as it relied on the CLRA, as that statute is inapplicable to loans for the purchase of real estate. In determining that leave to amend had been properly denied, we noted that Boyd had not shown that she could state a claim for wrongful foreclosure. We stated: "[A]lthough [Boyd] refers broadly to 'irregularities in the ... sale' " and inadequacy of the sale price, she offers no allegations detailing the purported misconduct, and no legal authority showing that any such misconduct supports the proposed claims ...."
On July 16, 2015, Boyd commenced the underlying action. Her first amended complaint (FAC) contains claims for wrongful foreclosure, vacation of the trustee's sale and the trustee's deed upon sale, unjust enrichment, and *853quiet title, based on allegations that Freeman "caused an illegal, fraudulent or willfully oppressive sale" of the Glendale property. The FAC alleges that the secured note was void-and thus provided no basis for the sale-because it *169fraudulently stated it had been arranged by a mortgage broker; that Freeman's notice of default overstated the amount in default; that he contravened Civil Code section 2924f by failing to post timely written notices of the foreclosure sale, and "in other particulars"; and that he bought the property at the sale for less that its true value.
Freeman demurred to the FAC, contending that under the doctrine of res judicata, the order of dismissal in Boyd's prior action barred the claims in the FAC. After sustaining the demurrer without leave to amend, the trial court entered a judgment in favor of Freeman and against Boyd. This appeal followed.
DISCUSSION
Boyd contends the trial court erred in sustaining the demurrer to the FAC without leave to amend. For the reasons discussed below, we agree.
A. Standard of Review
"Because a demurrer both tests the legal sufficiency of the complaint and involves the trial court's discretion, an appellate court employs two separate standards of review on appeal. [Citation.] ... Appellate courts first review the complaint de novo to determine whether or not the ... complaint alleges facts sufficient to state a cause of action under any legal theory, [citation], or in other words, to determine whether or not the trial court erroneously sustained the demurrer as a matter of law. [Citation.]" ( Cantu v. Resolution Trust Corp. (1992) 4 Cal.App.4th 857, 879, 6 Cal.Rptr.2d 151, fn. omitted ( Cantu ).) "Second, if a trial court sustains a demurrer without leave to amend, appellate courts determine whether or not the plaintiff could amend the complaint to state a cause of action. [Citation.]" ( Id. at p. 879, fn. 9, 6 Cal.Rptr.2d 151.)
Under the first standard of review, "we examine the complaint's factual allegations to determine whether they state a cause of action on any available legal theory. [Citation.] We treat the demurrer as admitting all material facts which were properly pleaded. [Citation.] However, we will not assume the truth of contentions, deductions, or conclusions of fact or law [citation], and we may disregard any allegations that are contrary to the law or to a fact of which judicial notice may be taken. [Citation.]" ( Ellenberger v. Espinosa (1994) 30 Cal.App.4th 943, 947, 36 Cal.Rptr.2d 360.)
Under the second standard of review, the burden falls upon the plaintiff to show what facts he or she could plead to cure the existing defects in the *854complaint. ( Cantu, supra, 4 Cal.App.4th at p. 890, 6 Cal.Rptr.2d 151.) "To meet this burden, a plaintiff must submit a proposed amended complaint or, on appeal, enumerate the facts and demonstrate how those facts establish a cause of action." ( Ibid. )
B. Governing Principles
The key issues concern whether the order of dismissal in the prior action barred the claims in the FAC under the doctrine of res judicata or a related doctrine. The term "res judicata" is often used as an umbrella term encompassing the principles of claim preclusion and issue preclusion, viewed as two separate aspects of a single doctrine. ( DKN Holdings LLC v. Faerber (2015) 61 Cal.4th 813, 824, 189 Cal.Rptr.3d 809, 352 P.3d 378 ( DKN Holdings ).) "Claim preclusion, the ' " 'primary aspect' " ' of res judicata, acts to bar claims that were, or should have been, advanced in a previous suit involving the same parties. [Citation.] Issue preclusion, the ' " 'secondary aspect' " ' historically called collateral estoppel, describes the bar on *170relitigating issues that were argued and decided in the first suit." [Citation].) ( Id . at p. 824, 189 Cal.Rptr.3d 809, 352 P.3d 378, quoting Boeken v. Philip Morris USA, Inc. (2010) 48 Cal.4th 788, 797, 108 Cal.Rptr.3d 806, 230 P.3d 342 ( Boeken ).)
Unlike issue preclusion, claim preclusion is directed at "entire causes of action." ( DKN Holdings , supra , 61 Cal.4th at p. 824, 189 Cal.Rptr.3d 809, 352 P.3d 378.) Generally, "[c]laim preclusion arises if a second suit involves: (1) the same cause of action (2) between the same parties (3) after a final judgment on the merits in the first suit." ( Ibid . ) In contrast, "issue preclusion applies: (1) after final adjudication (2) of an identical issue (3) actually litigated and necessarily decided in the first suit and (4) asserted against one who was a party in the first suit or one in privity with that party." ( Id . at p. 825, 189 Cal.Rptr.3d 809, 352 P.3d 378.)
Our focus is on the bar rule of claim preclusion, which limits litigation by plaintiffs. ( Busick v. Workmen's Comp. Appeals Bd. (1972) 7 Cal.3d 967, 973, 104 Cal.Rptr. 42, 500 P.2d 1386.) Under this rule, "a judgment for the defendant serves as a bar to further litigation of the same cause of action." ( Mycogen Corp. v. Monsanto Co. (2002) 28 Cal.4th 888, 896, 123 Cal.Rptr.2d 432, 51 P.3d 297 ( Mycogen Corp .), fn. omitted.) The rule "promotes judicial economy and avoids piecemeal litigation by preventing a plaintiff from ' " 'splitting a single cause of action or relitigat[ing] the same cause of action on a different legal theory or for different relief.' " ' [Citation.]" ( Ivanoff v. Bank of America, N.A. (2017) 9 Cal.App.5th 719, 727, 215 Cal.Rptr.3d 442 ( Ivanoff ), quoting Mycogen Corp. , supra , 28 Cal.4th at p. 897, 123 Cal.Rptr.2d 432, 51 P.3d 297.)
For purposes of the bar rule, California law identifies a single cause of action as "the violation of a single primary right." ( *855Crowley v. Katleman 1994) 8 Cal.4th 666, 681, 34 Cal.Rptr.2d 386, 881 P.2d 1083.) "The plaintiff's primary right is the right to be free from a particular injury, regardless of the legal theory on which liability for the injury is based. [Citation.] The scope of the primary right therefore depends on how the injury is defined. A cause of action comprises the plaintiff's primary right, the defendant's corresponding primary duty, and the defendant's wrongful act in breach of that duty. [Citation.]" ( Federation of Hillside & Canyon Assns. v. City of Los Angeles (2004) 126 Cal.App.4th 1180, 1202, 24 Cal.Rptr.3d 543.) Thus, under the bar rule, a complaint may contain several counts, each of which relies on a different legal theory, yet collectively assert only a single violation of a specific primary right, that is, a single cause of action. ( Boeken, supra, 48 Cal.4th at p. 798, 108 Cal.Rptr.3d 806, 230 P.3d 342.) Whether the facts alleged in a complaint constitute the violation of a single primary right, or more than one such right, requires an examination of the harm asserted, in conjunction with relevant judicial precedent. ( Ivanoff , supra , 9 Cal.App.5th at p. 728, 215 Cal.Rptr.3d 442 ; Sawyer v. First City Financial Corp. (1981) 124 Cal.App.3d 390, 399-403, 177 Cal.Rptr. 398 ( Sawyer ).)
The bar rule is properly raised as a defense on demurrer when all relevant facts "are within the complaint or subject to judicial notice."3 ( *171Carroll v. Puritan Leasing Co. (1978) 77 Cal.App.3d 481, 485, 143 Cal.Rptr. 772 ; see Barker v. Hull (1987) 191 Cal.App.3d 221, 226-227, 236 Cal.Rptr. 285.) Furthermore, that defense may be invoked even when the prior judgment resulted from the sustaining of a demurrer, provided that the judgment was "on the merits." ( Kanarek v. Bugliosi (1980) 108 Cal.App.3d 327, 330, 331, 334, 166 Cal.Rptr. 526.) Whether the prior judgment was on the merits depends upon the facts of the case and the reason for the ruling. ( Ibid . ) A judgment based upon the sustaining of a demurrer for technical or formal defects is not on the merits and thus is not a bar to the filing of the new action. ( Goddard v. Security Title Ins. & Guar. Co. (1939) 14 Cal.2d 47, 52, 92 P.2d 804.) "On the other hand, it is generally held that a demurrer which is sustained for failure of the facts alleged to establish a cause of action, is a judgment on the merits. However, this is true only if the same facts are pleaded in the second action [citation], or if, although different facts are pleaded, the new complaint contains the same defects as the former." ( Kanarek v. Bugliosi , supra , 108 Cal.App.3d at p. 334, 166 Cal.Rptr. 526.) *856Under the bar rule, a prior judgment based on the statute of limitations ordinarily is not on the merits. In Mid-Century Ins. Co. v. Superior Court (2006) 138 Cal.App.4th 769, 773, 41 Cal.Rptr.3d 833 ( Mid-Century Ins. Co .), the plaintiff sued his insurer for breach of contract, negligence, bad faith, and fraud, alleging that the insurer mishandled his insurance claim relating to damage resulting from the 1994 Northridge earthquake. After the trial court sustained a demurrer to the complaint without leave to amend because the applicable limitations period had run, the Legislature enacted a statute extending the limitations period for some lawsuits arising from the Northridge earthquake. ( Id . at pp. 773-774, 41 Cal.Rptr.3d 833.) Relying on that statute, the plaintiff initiated a second action against the insurer in which he asserted the same claims. ( Ibid . ) The insurer requested judgment on the pleadings, arguing that the doctrine of res judicata barred the second action. ( Ibid . ) When the trial court denied that request, the insurer sought relief by writ. ( Ibid . ) Affirming the denial of judgment on the pleadings, the appellate court concluded that the judgment in the first action on the basis of the statute of limitations was not "on the merits." ( Id . at pp. 774, 776-777, 41 Cal.Rptr.3d 833.)
In Koch v. Rodlin Enterprises (1990) 223 Cal.App.3d 1591, 1593, 1594-1596, 273 Cal.Rptr. 438 ( Koch ), the plaintiff initiated a lawsuit, alleging that the defendants had created and sold subdivision land in violation of the California Subdivision Map Act ( Gov. Code, §§ 66410 - 66499.37 ). When the defendants sought summary judgment on the claims on the basis of the applicable statute of limitations, the plaintiff requested leave to amend the complaint to include a fraud claim, which he contended was not time-barred. ( Koch v. Rodlin Enterprises at p. 1594, 273 Cal.Rptr. 438.) The trial court granted summary judgment and denied leave to amend. ( Ibid . ) The plaintiff then filed a second action for fraud against the defendants, who successfully demurred on the ground of res judicata, and secured a judgment in their favor. ( Id . at p. 1595, 273 Cal.Rptr. 438.) Reversing, the appellate court held that "[t]ermination of an action by a statute of limitations is ... a *172technical or procedural, rather than a substantive, termination." ( Id . at p. 1596, 273 Cal.Rptr. 438.)
Under the bar rule, a judgment due to a demurrer to potentially curable defects in the complaint's allegations also is not on the merits. In Keidatz v. Albany (1952) 39 Cal.2d 826, 827, 249 P.2d 264 ( Keidatz ), the plaintiffs, after buying a newly-constructed home, brought an action to rescind the contract on the basis of fraud. A demurrer was sustained to the complaint, as the plaintiffs had engaged in undue delay in seeking rescission, and the complaint lacked allegations sufficient to state a fraud claim for damages. ( Id . at p. 829, 249 P.2d 264.) Although the plaintiffs were granted leave to amend, they failed to file an amended complaint, and judgment was entered against them. ( Ibid . ) They then commenced a second action, seeking damages rather than rescission. ( Id . at pp. 827-828, 249 P.2d 264.) Their complaint asserted a fraud claim for damages, and contained new allegations necessary for such a claim but absent *857from their prior complaint. ( Id . at p. 828, 249 P.2d 264.) Relying on the bar rule, the defendant successfully secured summary judgment. ( Id . at p. 829, 249 P.2d 264.) Our Supreme Court reversed, concluding that the newly alleged facts barred the application of claim preclusion. ( Id . at pp. 828-829, 249 P.2d 264.)
C. Analysis
Upon sustaining Freeman's demurrer to the FAC, the trial court concluded that Boyd's actions involved the same primary right, as both actions challenged Freeman's conduct in connection with the foreclosure sale, and sought recovery of the Glendale property. In so ruling, the court observed that Boyd's complaints in the first action contained allegations asserting Freeman's noncompliance with the nonjudicial foreclosure scheme, which constituted a key basis for her claims in her second action.
Although we agree that both actions involved one primary right in common-namely, the right associated with the nonjudicial foreclosure scheme-the judgment in the first action was not on the merits with respect to that primary right, and thus did not bar Boyd's second action.4 In sustaining the demurrer underlying the judgment in the first action, the trial court ruled primarily that Boyd's claims were time-barred, which is not a determination "on the merits." ( Mid-Century Ins. Co. , supra , 138 Cal.App.4th at p. 774, 41 Cal.Rptr.3d 833 ; Koch , supra , 223 Cal.App.3d at pp. 1596-1598, 273 Cal.Rptr. 438.)5
*173*858Freeman invokes a principle he terms "the rule against splitting a cause of action," which he maintains is distinct from the doctrine of res judicata, and requires no prior judgment on the merits for its application. He argues that the demurrer was properly sustained because the FAC involved "a single primary right, asserted in two successive proceedings, in violation of the theory of primary right, and thus in violation of the rule against the splitting of a cause of action," even though the judgment in the first action was not on the merits. The crux of his contention is that Boyd's second action is an impermissible "effort to circumvent ... the rulings ... in the [f]irst [l]awsuit denying her leave to amend." We disagree.
Under California law, the rule against splitting a cause of action is not independent of the doctrine of res judicata. ( Hamilton v. Asbestos Corp. (2000) 22 Cal.4th 1127, 1146, 95 Cal.Rptr.2d 701, 998 P.2d 403.) As our Supreme Court has explained, the rule against splitting a cause of action reflects the application of the primary right theory, and "is in part a rule of abatement and in part a rule of res judicata." ( Ibid., italics omitted.) " '[W]hen a plaintiff attempts to divide a primary right and enforce it in two suits,' " the primary right theory prevents this result in two ways: " '(1) if the first suit is still pending when the second is filed, the defendant in the second suit may plead that fact in abatement ...; [and] (2) if the first suit has terminated in a judgment on the merits adverse to the plaintiff, the defendant in the second suit may set up that judgment as a bar under the principles of res judicata [citation].' "6 ( Ibid ., italics omitted, quoting Panos v. GreatWestern Packing Co. (1943) 21 Cal.2d 636, 638-640, 134 P.2d 242 ). So understood, the rule against splitting a cause of action incorporates the bar rule of claim preclusion. For that reason, the former reflects policy considerations similar to those underlying the latter, namely, the reduction of vexatious litigation and the conservation of judicial resources. ( Weikel v. TCW Realty Fund II Holding Co. (1997) 55 Cal.App.4th 1234, 1250-1251, 65 Cal.Rptr.2d 25.)
*174Boyd's second action did not contravene the rule against splitting a cause of action, as the judgment in her first action was not "on the merits"
*859with respect to the key primary right underlying her claims in the second action. In the absence of a judgment on the merits, the bar rule of claim preclusion did not disallow Boyd's new claims for unlawful foreclosure predicated on additional factual allegations. ( Keidatz , supra , 39 Cal.2d at pp. 828-829, 249 P.2d 264.) Nor did the denial of leave to amend in the first action do so. As our Supreme Court has explained, "[i]f ... new or additional facts are alleged that cure the defects in the original pleading, it is settled that the former judgment is not a bar to the subsequent action whether or not plaintiff had an opportunity to amend his complaint." ( Id . at p. 828, 249 P.2d 264 ; see Sterling v. Galen (1966) 242 Cal.App.2d 178, 184, fn. 2, 51 Cal.Rptr. 312 ["The fact that defendants' general demurrers were sustained without leave to amend in the first action is not, of course, determinative of the question of res judicata"].)
Freeman's reliance on Ricard v. Grobstein, Goldman, Stevenson, Siegel, LeVine & Mangel (1992) 6 Cal.App.4th 157, 8 Cal.Rptr.2d 139 ( Ricard ) is misplaced, as that decision is founded on principles not applicable here, notwithstanding its reference to the policy considerations underlying the rule against splitting of a cause of action. There, the plaintiffs sued a law firm, seeking punitive damages. ( Ricard , supra , 6 Cal.App.4th at p. 159, 8 Cal.Rptr.2d 139.) After sustaining demurrers to portions of the complaint and first amended complaint, the trial court struck the request for punitive damages without leave to amend. ( Ibid . ) The plaintiffs then sought to file a second amended complaint requesting punitive damages on the basis of a new claim for conspiracy to commit fraud, but the trial court denied leave to file it. ( Ibid . ) While the initial action was pending and without the filing of a notice of a related case as required under local rules, the plaintiffs commenced a second action in a different district of the same superior court. ( Ibid . ) The new action was limited to the identical claim for conspiracy to commit fraud and request for punitive damages they had unsuccessfully sought to add to their complaint in the first action. ( Ibid . ) In the second action, the law firm demurred on the ground that the complaint was "another patent attempt to circumvent the ... ruling" in the first action. ( Ibid . ) After the second action was transferred to the superior court district in which the first action was pending, the trial court there sustained the demurrer without leave to amend and entered a judgment of dismissal. ( Id . at pp. 159-160, 8 Cal.Rptr.2d 139.)
The plaintiffs appealed from the judgment in the second action, contending that the sustaining of the demurrer on the basis of collateral estoppel-that is, issue preclusion-was improper, as there was no final judgment on the merits in the first action. ( Ricard , supra , 6 Cal.App.4th at pp. 159-160, 8 Cal.Rptr.2d 139.) The appellate court concluded that collateral estoppel was not the actual basis for the ruling, as the trial court had expressly characterized the ruling in the first action as " 'just an interlocutory order.' " ( Id . at pp. 161, 162, 8 Cal.Rptr.2d 139.) The appellate court further concluded that the dismissal of the second action was proper in *860view of the trial court's statutory authority to strike "any pleading not drawn or filed in conformity with ... an order of the court" ( Code Civ. Proc., § 436, subd. (b) ) and its "inherent discretionary power" to dismiss sham claims ( Lyons v. Wickhorst (1986) 42 Cal.3d 911, 915, 231 Cal.Rptr. 738, 727 P.2d 1019 ).7 *175( Ricard , supra , at p. 162, 8 Cal.Rptr.2d 139.) The appellate court stated: "With almost frightening candor appellants acknowledge that the present suit was filed solely to circumvent the court's prior adverse ruling. Consequently, it could properly be struck ...." ( Ibid . ) In so concluding, the appellate court discussed the theory of primary rights and remarked that the second action "split [the plaintiffs'] cause of action in violation of the policy against misuse of court time." ( Ibid . ) The appellate court further observed that the plaintiffs' appropriate course of action was to seek review of the adverse ruling in the first action by appeal or writ proceeding. ( Ibid . )
Nothing in Ricard suggests the existence of a doctrine properly denominated a "rule against splitting a cause of action" permitting a court to sustain a demurrer in the absence of a prior judgment on the merits. The holding in Ricard relied on the trial court's statutory and inherent authority to strike complaints that circumvent a prior court order. Although the appellate court alluded to the rule against splitting a cause of action, its remark, viewed in context, conveyed only that a policy consideration underlying that rule-rather than the rule itself-supported the sustaining of the demurrer in the second action.
Furthermore, the rationale in Ricard is inapplicable here because Boyd's second action improperly circumvented no court order. As explained above, although there was a final judgment in the first action, it was not on the merits. In the absence of such a judgment, the bar rule of claim preclusion did not prevent Boyd from asserting the claims in the FAC, even though she had been denied leave to amend in the first action. ( Keidatz , supra , 39 Cal.2d at pp. 828-829, 249 P.2d 264.) Furthermore, unlike the plaintiffs in Ricard , Boyd contravened no court rules in initiating the underlying action; on the contrary, she engaged in conduct ordinarily regarded as unexceptional.
Friedman v. Stadum (1985) 171 Cal.App.3d 775, 217 Cal.Rptr. 585, upon which Freeman also relies, is inapposite, as it contains no discussion of res judicata or the rule against splitting a cause of action. There, an attorney and his client brought an action for defamation against an expert witness they had previously hired. ( Id . at p. 777, 217 Cal.Rptr. 585.) After the expert witness secured a judgment in his favor in the defamation action-but before that judgment became *861final-the expert witness commenced a malicious prosecution action against the attorney and his client. ( Id . at pp. 777-778, 217 Cal.Rptr. 585.) The attorney then successfully demurred to the malicious prosecution claim on the ground that it was premature, due to a pending appeal in the defamation action. ( Id . at p. 778, 217 Cal.Rptr. 585.) Affirming, the appellate court concluded that the expert witness could not demonstrate an element required for a malicious prosecution claim, namely, "that the underlying proceeding [had] terminated in his favor." ( Id. at pp. 778, 779, 217 Cal.Rptr. 585.) That conclusion implicates neither res judicata nor the rule against splitting a cause of action. In sum, the demurrer to the FAC was improperly sustained.8 *176*862DISPOSITION
The order of dismissal is reversed, and the matter is remanded for further proceedings in accordance with this opinion. Boyd is awarded her costs on appeal.
