Fraudulent or unfair business practices

Section 17200 prohibits unlawful, unfair, or fraudulent business acts or practices; a breach of contract alone is insufficient under its unlawful prong, and a UCL claim requires an unfair or deceptive act.

Dameron Hospital Assoc. v. Geico General Ins. Co. · filed 2025-06-24

The UCL protects California's consumers by prohibiting any “unlawful, unfair or fraudulent business act or practice.” Cal. Bus. & Prof. Code § 17200. As relevant here, when assessing UCL claims, the Court considered whether a defendant’s actions are unlawful or unfair. ... Under the unlawful prong of the UCL, a plaintiff must allege more than a common law violation of breach of contract. ... Common law violations for breach of contract do not offend the UCL, and therefore, Plaintiff’s claims under this prong are not viable. ... While there is no exact definition of unfairness under the UCL, California courts have generally proscribed “unfair” or “deceptive” acts, even if those acts are not “unlawful.” ... And while J.M.’s agreement has not been deemed an unenforceable contract of adhesion and therefore may be valid, Plaintiff does not identify any unfair or deceptive acts that would invoke the UCL.

Section 17200 prohibits unlawful, unfair, or fraudulent business acts or practices, and each prong is a separate theory of liability.

Albrigo v. Chobani, LLC · filed 2025-07-11

The UCL prohibits any “unlawful, unfair or fraudulent business act or practice.” Cal.Bus. & Prof. Code § 17200. “Each prong of the UCL is a separate and distinct theory of liability[.]” Kearns, 567 F.3d at 1127 (citing South Bay Chevrolet v. General Motors Acceptance Corp., 72 Cal. App. 4th 861 (1999)). ... In sum, Plaintiff has sufficiently pled that the inclusion of stevia extract, monk fruit extract, and MCA in products labeled “Only Natural Ingredients” is likely to deceive a reasonable consumer under the UCL and FAL. Therefore, Defendant’s motion to dismiss is DENIED on these claims.

Section 17200 prohibits unlawful, unfair, or fraudulent business acts or practices, and a violation of almost any federal, state, or local law may support a claim under its unlawful prong.

RL Liquidators LLC v. Amazon.com Services LLC · filed 2025-07-15

RL does not state a UCL claim. The UCL prohibits “any unlawful, unfair or fraudulent business act or practice.” Cal. Bus. & Prof. Code § 17200. Under the “unlawful” prong, “[v]iolation of almost any federal, state, or local law may serve as the basis for a UCL claim.” ... But RL neither states a WCPA claim nor specifies other statutes to support its claim. As for the “unfair” and “fraudulent” prongs, RL relies on factual allegations that are not set forth in the UCL section of its complaint. Thus, Amazon did not have “fair notice” to “defend itself effectively” against these formulations of the UCL claim.

Section 17200 defines unfair competition to include unlawful, unfair, or fraudulent business acts or practices, with each prong providing an independent theory of liability.

Snowman v. FCA US LLC · filed 2025-07-24

The California UCL proscribes “unfair competition,” which is defined as “any unlawful, unfair or fraudulent business act or practice[.]” Cal. Bus. & Prof. Code § 17200; see In re Toyota RAV4 Hybrid Fuel Tank Litig., 534 F. Supp. 3d 1067, 1100 (N.D. Cal. 2021). Each of the “unlawful,” “unfair,” and “fraudulent” prongs of the UCL provides a separate theory of liability and an independent basis for relief.

Section 17200 defines unfair competition to include unlawful, unfair, or fraudulent business acts or practices, and a UCL claim may proceed when it is based on a business practice allegedly violating another law.

Floyd v. Saber Fitness Hegenberger, LLC · filed 2025-07-31

“Unfair competition” includes “any unlawful, unfair or fraudulent business act or practice and unfair, deceptive, untrue or misleading advertising.” Cal. Bus. & Prof. Code § 17200. ... Here, construing all evidence in the light most favorable to Floyd, the Court finds that a reasonable jury could find that Saber’s business practices were unlawful. Under the Unruh Act, Floyd is a member of a protected class. TAC ¶¶ 22–23; Opp. at 14:5–6. As discussed above, a reasonable jury could find that Saber discriminated against Floyd based on his protected characteristics. Because Floyd’s UCL claim is directly tethered to Saber’s alleged violation of the Unruh Act, the UCL claim also survives summary judgment. See Candelore v. Tinder, Inc., 19 Cal. App. 5th 1138, 1155 (2018) (explaining that a violation of the Unruh Act constitutes violation of the UCL’s unlawful prong). Therefore, summary judgment in Saber’s favor is not warranted.

Section 17200 prohibits business practices that are unlawful, unfair, or fraudulent, and a claim may be based on any or all three prongs.

Pitre v. Kevita, Inc. · filed 2025-08-08

“Because the UCL is written in the disjunctive, it established three varieties of unfair competition—acts or practices which are unlawful, or unfair, or fraudulent. ... “An act can be alleged to violate any or all of the three prongs of the UCL—unlawful, unfair, or fraudulent.” ... The Court will dismiss Pitre’s UCL claim. As stated above, she has not plausibly alleged that KeVita’s labels are “fraudulent.” Nor has she established that KeVita’s conduct was “unlawful” or “unfair”: her claims under both prongs depend on the allegation that KeVita is “promising a health benefit that the Product cannot confer” because consumers must drink more than three cans of KeVita’s Sparkling Lemonade to improve gut health. ... Plaintiff has not plausibly alleged that consumption of that amount of KeVita’s product is actually required.

Section 17200 creates a cause of action against unlawful, unfair, or fraudulent business practices, including an unfair practice even if no other law prohibits it.

Barton v. The Procter & Gamble Company · filed 2025-08-08

The UCL prohibits “any [1] unlawful, [2] unfair or [3] fraudulent business act or practice.” ... The “unfair” prong of the UCL creates a cause of action for a business practice that is unfair even if not proscribed by some other law. ... The Court agrees, and finds these allegations are too conclusory and insufficient to plausibly allege a UCL claim under the “unfair” prong. ... The Court GRANTS the motion to dismiss the UCL claim premised on the “unfair” prong. ... Plaintiffs are entitled to proceed with the UCL under the unlawful prong based upon an alleged violation of the CLRA (Civil Code § 1770) since the affirmative misrepresentation claim is moving forward, see supra. ... Based on the reasoning above, the Court GRANTS the Motion as to the UCL claim premised on the unfair prong with prejudice, and DENIES the Motion as to the rest of the claims.

California law prohibits “any unlawful, unfair, or fraudulent business act or practice.” Cal. Bus. & Prof. Code § 17200. “Section 17200 incorporates other laws and treats violations of those laws as unlawful business practices independently actionable under state law.” Causey v. Portfolio Acquisitions, LLC, No. 2:10-cv-2781-KJM-EFB PS, 2013 WL 246916, at *3 (E.D. Cal. Jan. 22, 2013). A § 17200 claim can be based on a violation of almost any federal, state, or local law. Id. (citing Saunders v. Super. Ct., 27 Cal. App. 4th 832, 838–39 (1994)) ... Here, the Court finds Plaintiffs do not raise serious questions as to the merits of this claim. First, as discussed above, the Court finds Plaintiffs do not raise serious questions regarding the underlying claims. Second, while the Court is sympathetic to Plaintiffs’ argument about building equity in their home, in light of the evidence Defendant presents regarding the letters that were sent directly to Plaintiffs’ property between 2015 to the present, the Court finds Plaintiffs argument about unfairness unavailing.

Section 17200 permits challenges to business practices as unlawful, unfair, or fraudulent, including practices that violate another law.

Gutierrez · filed 2025-09-22

The UCL prohibits “any unlawful, unfair[,] or fraudulent business act or practice.” Cal. Bus. & Prof. Code § 17200. ... A plaintiff may pursue a claim under California’s UCL via any or all of three prongs: the “unlawful” prong, which bars practices that are forbidden by any other law; the “unfair” prong, which bars unfair conduct; and the “fraudulent” prong, which bars practices that are likely to deceive the public. ... In sum, the Court finds Statements 1-7 are not nutrient content claims and Plaintiff therefore fails to state a UCL unlawful claim as to Statements 1-7. The Court further finds that Plaintiff has sufficiently pled that Statements 8-10 are implied nutrient content claims. Because nutrient content claims are not permitted on food intended for use by infants and children less than 2 years of age, the Product is intended for use for infants and children 12-36 months old, and Plaintiff has sufficiently pled that Statements 8-10 are implied nutrient content claims, Defendant’s motion to dismiss should be denied on Plaintiff’s UCL unlawful claim as to Statements 8-10. ... Here, as set forth above, the Court finds Plaintiff adequately pleads a claim under the “unlawful” prong of the UCL for Statements 8-10. The Court therefore similarly finds Plaintiff adequately establishes a claim under the unfair prong. Accordingly, Defendant’s motion to dismiss Plaintiff’s unfair UCL claim should be denied.

Section 17200 permits liability under unlawful, unfair, or fraudulent business-practice prongs; an unlawful-prong claim requires pleading another statutory or common-law violation, and equitable relief requires no adequate remedy at law.

Vargas v. Lockheed Martin Corporation et al. · filed 2025-10-20

The UCL prohibits “unlawful, unfair[,] or fraudulent business act[s] or practice[s].” Cal. Bus. & Prof. Code § 17200. As “[e]ach of these three adjectives captures a separate and distinct theory of liability,” Rubio v. Cap. One Bank, 613 F.3d 1195, 1203 (9th Cir. 2010) (internal quotation marks omitted), a business practice can violate one prong or all three, Berryman v. Merit Prop. Mgmt., Inc., 152 Cal. App. 4th 1544, 1554 (2007). A UCL claim brought under the unlawful prong “borrows violations of other laws and treats” them as unlawful business practices that are “independently actionable under section 17200.” Farmers Ins. Exch. v. Superior Ct., 2 Cal. 4th 377, 383 (1992). Accordingly, to state a UCL claim under the unlawful prong, a plaintiff must plead a violation of another statute or common law. Moreover, because the UCL provides for only equitable remedies, Nationwide Biweekly Admin., Inc. v. Superior Ct., 9 Cal. 5th 279, 292 (2020), a plaintiff must also establish that there is “no adequate remedy at law available,” Philips v. Ford Motor Co., No. 14-cv-02989-LHK, 2015 WL 4111448, at *16 (N.D. Cal. July 7, 2015) (citing Knox v. Phoenix Leasing, Inc., 29 Cal. App. 4th 1357, 1368 (1994)).

California’s UCL prohibits “any unlawful, unfair, or fraudulent business act or practice.” ...

Under the UCL's fraudulent prong, a business practice is fraudulent when consumers are likely to be deceived; common-law fraud is not required.

Hughes v. Ester C Co. · filed 2013-03-15

The term “fraudulent,” as used in the UCL, “does not refer to the common law tort of fraud.” ... Thus, for a business act or practice to be deemed “fraudulent” under the UCL, a plaintiff must allege that “consumers are likely to be deceived by the defendant’s conduct.” ... Thus, plaintiffs sufficiently state a cause of action under the “fraudulent” prong of the UCL.

Deno v. State Farm General Insurance Company · filed 2022-09-08

The UCL defines “unfair competition” to include “any ‘unlawful, unfair, or fraudulent business act or practice.” ... The statute’s “coverage is sweeping, embracing anything that can properly be called a business practice and that at the same time is forbidden by law.” ... “By proscribing ‘any unlawful’ business practice, section 17200 ‘borrows’ violations of other laws and treats them as unlawful practices that the unfair competition law makes independently actionable.” ... Consequently, “[c]onduct that is independently actionable under some other law can form the basis of a UCL claim.” ... “That is enough under the UCL.”

Section 17200 defines unfair competition to include unlawful, unfair, or fraudulent business acts or practices, with each prong providing a separate theory of liability.

Ray v. U.S. Bank Trust, N.A. · filed 2023-05-01

Section 17200 prohibits unfair competition, which is defined as, inter alia, “any unlawful, unfair or fraudulent business act or practice.” Cal. Bus. Prof. Code § 17200. Because section 17200 “is written in the disjunctive, it establishes three varieties of unfair competition—acts or practices which are unlawful, or unfair, or fraudulent....” Cel–Tech Communications, Inc. v. Los Angeles Cellular Telephone Co., 20 Cal. 4th 163, 180 (1999). To state a claim under the unlawful prong, a plaintiff must allege facts that show that any of a defendant’s business practices—or conduct which can be characterized as a business practice—violates the law, meaning any civil or criminal, federal, state or municipal, statutory, regulatory, or court-made law. California v. McKale, 25 Cal. 3d 626, 632 (1979). Conduct is “fraudulent” if it is likely to deceive any member of the public. Weinstat v. Dentsply Int’l., Inc., 180 Cal. App. 4th 1213 n. 8 (2010). Whether a business practice is “unfair” requires an analysis of whether (i) there exists substantial consumer injury, (ii) the injury is not outweighed by countervailing benefits to consumers or competition, and (iii) the injury was not reasonably avoidable by the consumer. Camacho v. Auto. Club of So. Cal., 142 Cal. App. 4th 1294, 1403 (2006).

Section 17200 covers unlawful, unfair, or fraudulent business practices; a UCL claim may rest on a violation of another law, and the available remedies are restitution and injunctive relief.

Jiminian v. PHH Mortgage Services · filed 2026-01-16

Under the UCL, unfair competition includes any “unlawful, unfair or fraudulent business act or practice.” Cal. Bus. & Prof. Code § 17200. Therefore, there are three prongs under which a claim may be established under section 17200. ... Further, a claim under section 17200 may rest on a violation of another law. ... Plaintiffs are correct that the allegations alleged in claims one through four can provide the predicate for a violation of the UCL as alleged in count 5. ... Because Plaintiffs have sufficiently pleaded a violation of section 2923.5, and because the remedies provided in section 2924.19 are not exclusive, see § 2924.19(g), the undersigned finds that Plaintiffs have sufficiently alleged the unlawful prong to establish a UCL violation. However, as Defendants correctly note, only restitution and injunctive relief are available under the UCL.

The fraudulent prong of section 17200 requires likely public deception; a failure to disclose supports a claim only when there is a duty to disclose.

Brakke v. Economic Concepts, Inc. · filed 2013-01-15

But California cases have recognized “ ‘[i]n order to be deceived, members of the public must have had an expectation or an assumption about’ the matter in question” (Daugherty v. American Honda Motor Co., Inc., supra, 144 Cal.App.4th at p. 838), and “[a]bsent a duty to disclose, the failure to do so does not support a claim under the fraudulent prong of the UCL” (Berryman v. Merit Property Management, Inc. (2007) 152 Cal.App.4th 1544, 1557 [62 Cal.Rptr.3d 177]). Given the representations in ECI’s marketing materials and opinion letters that its 412(i) plan “ ‘more likely than not’ ” would qualify for favorable tax treatment, plaintiffs do not explain how they can allege they could reasonably expect or assume the IRS would never disqualify their plan or revise its interpretation of the tax laws. Nor do plaintiffs explain how they could amend the complaint to allege ECI would have a duty to inform clients of the possibility of a future change in tax law.

Pleading requirements for UCL claims

Section 17200’s unlawful, unfair, and fraudulent prongs are separate, and the unfair-practices prong independently supports UCL relief; a UCL claim alleging a unified fraudulent course must satisfy Rule 9(b)’s particularity requirement in federal court.

Section 17200 claims based on deceptive advertising require particularized pleading of reasonable reliance, evaluated from the viewpoint of a reasonable consumer.

Stemmelin v. Matterport, Inc. · filed 2020-11-07

Rule 9’s heightened pleading requirement plays substantive role here. California’s unfair competition and false advertising laws sound in fraud and require a plaintiff’s reliance on a misrepresentation to be reasonable under the circumstances. See Kwikset, 51 Cal. 4th at 326–27; Hobart v. Hobart Estate Co., 26 Cal. 2d 412, 447 (1945). Under the unfair competition and false advertising laws, this requirement manifests as the “reasonable consumer” test. We evaluate deceptive advertising from the viewpoint of a reasonable consumer and so require the plaintiff to offer a reasonable interpretation of the ad likely shared by ordinary consumers in general, as opposed to a particular subset of consumers viewing the ad unreasonably. The complaint’s failure to allege more than that Stemmelin saw an ad and purchased a product prevents us from evaluating whether Stemmelin reasonably relied, as ordinary consumers Becerra, 945 F.3d at 1228–31. The claims under California’s false advertising and unfair competition law fail under Rule 9.

Unlawful business practices

The UCL's unlawful prong borrows violations of other laws, so a plaintiff who cannot state a claim under the borrowed law cannot state a UCL claim either.

(PS) Matthews v. Caliber Home Loans · filed 2020-01-31

California’s unfair competition law prohibits “unlawful, unfair[,] or fraudulent” business acts or practices. See Cal. Bus. & Prof. Code §§ 17200, et seq.; Korea Supply Co. v. Lockheed Martin Corp., 29 Cal. 4th 1134, 1143–44 (2003) (describing how § 17200 covers a “wide range of conduct” and embraces “anything that can properly be called a business practice and that at the same time is forbidden by law.”). “The UCL's ‘unlawful’ prong looks to other sources of substantive law . . . borrow[ing] violations of other laws and treats them as unlawful practices that the unfair competition law makes independently actionable.” Beaver v. Tarsadia Hotels, 816 F.3d 1170, 1177 (9th Cir. 2016). Here, Plaintiff’s ninth cause of action under the UCL alleges Defendants committed unlawful acts “[b]y recording the [notice of default] and [notice of trustee sale] in violation of California Civil Code § 2924(a)(6).” (ECF No. 9 at ¶ 116.) Defendant counters that because Plaintiff’s claim is predicated on the same facts as his fraud claims (See Section I.A. and B. above), his UCL claim likewise fails. The Court agrees. A plaintiff who “cannot state a claim under the ‘borrowed’ law . . . cannot state a UCL claim either.” Lopez v. Stages of Beauty, LLC, 307 F. Supp. 3d 1058, 1070 (S.D. Cal. 2018).

Cal. Civ. Code §§ 1738.13, 1738.15. The contract was in writing, it complied with the statutory requirements, and Belden paid Bosinger commissions in accordance with the written contract.

However, the Court finds that Washington’s claim under the “unfair” prong of the UCL does not survive dismissal. “The unfair prong of the UCL prohibits a business practice that violates established public policy or if it is immoral, unethical, oppressive or unscrupulous and causes injury to consumers which outweighs its benefits.”

Plaintiff’s second claim is governed by the UCL, which prohibits “any unlawful, unfair or fraudulent business act or practice.” Cal. Bus. & Prof. Code § 17200. Defendant argues that if Plaintiff cannot plead a Song-Beverly claim, then she necessarily cannot plausibly state a UCL claim. (Mot. at 9.) However, because the Court holds that Plaintiff has sufficiently pled a Song-Beverly claim, it holds that Plaintiff has also stated a claim for violation of the UCL, as she plausibly states that Defendant is engaged in an unlawful business practice.

The UCL prohibits “any unlawful, unfair or fraudulent business act or practice and unfair, deceptive, untrue or misleading advertising.” Cal. Bus. & Prof. Code § 17200. The UCL provides a separate theory of liability under each of the three prongs: “unlawful,” “unfair,” and “fraudulent.” ... For the “unlawful” prong, the “UCL “borrows” violations of other laws as unlawful practices and then provides an independent action.” ...

Section 17200 covers unlawful, unfair, and fraudulent business practices; its unlawful prong can be supported by violations of other laws without private rights of action, and credit damage can satisfy the loss-of-money-or-property requirement for relief under §§ 17203–17204.

Scott v. Healthcare Management Solutions, LLC, et al. · filed 2026-03-31et seq.

California’s unfair competition law (“CUCL”) defines “unfair competition” as “any unlawful, unfair or fraudulent business act or practice and unfair, deceptive, untrue or misleading advertising.” Cal. Bus. & Prof. Code § 17200 et seq. There are three different theories of liability: unlawful business practices, unfair business practices, and fraudulent business practices. ... The laws relied upon by a plaintiff under the unlawful prong need not provide the plaintiff with a right of action because the CUCL makes violations of these laws “independently actionable.” ... Either violation is sufficient to support a violation of the unlawful prong of the CUCL. ... The Court additionally concludes Scott adequately pled a violation of the CUCL’s unfair prong. ... Therefore, Scott adequately pled a violation of the unfair prong. ...

The unlawful prong of the UCL prohibits “anything that can properly be called a business practice and that at the same time is forbidden by law.” ...

Section 17200’s unlawful-business-practice theory cannot support state court injunctive relief for billboard conduct that California law cannot regulate on an Indian reservation.

People Ex Rel. Department of Transportation v. Naegele Outdoor Advertising Co. · filed 1985-05-02

This action is premised upon the language of Business and Professions Code section 17200 which defines “unfair competition” to include any “unlawful” business practice. Desert admits that if Naegele’s conduct is not forbidden by law, there is no unfair competition. We have concluded that California law cannot be applied to regulate the billboards at issue. And, even if Naegele’s conduct could somehow be construed as violative of federal law, state court injunctive relief under the theory of unfair competition is inappropriate.

Section 17200 applies to any unlawful act or practice, so a single instance of unfair conduct may support a claim.

Podolsky v. First Healthcare Corp. · filed 1996-10-29

Business and Professions Code section 17200 was once applicable only to unlawful business practices, requiring proof of a pattern or course of conduct, not just a single transaction. (State of California ex rel. Van de Kamp v. Texaco, Inc. (1988) 46 Cal.3d 1147, 1169-1170 [252 Cal.Rptr. 221, 762 P.2d 385].) That section was amended in 1992, however, to state that it applies to any unlawful “act or practice,” presumably permitting invocation of the UCA based on a single instance of unfair conduct. (Bus. & Prof. Code, § 17200, italics added; see Historical and Statutory Notes, 5 West’s Ann. Bus. & Prof. Code (1996 pocket supp.) § 17200, p. 30.) Even under the prior version of Business and Professions Code section 17200, however, we believe that declarations from several persons who had virtually identical experiences when admitting family members to various FHC nursing homes over a three-year period is sufficient to at least raise an inference that such a pattern or course of conduct exists. Whether this is actually so is for the trier of fact to determine.
