Few statutes appear in more California business lawsuits than Business and Professions Code § 17200, the Unfair Competition Law (UCL). Plaintiffs attach a UCL count to almost everything — contract disputes, employment claims, advertising fights — because the statute is broad and its four-year clock often outlives other claims. But the UCL is also narrower than it looks: its remedies are limited, and there is no right to a jury. Whether you are asserting a claim or defending one, understanding both halves is essential.
The three prongs: unlawful, unfair, fraudulent
Section 17200 prohibits "any unlawful, unfair or fraudulent business act or practice." Each word is an independent theory:
- Unlawful. The UCL "borrows" violations of virtually any other law — federal, state, or local, civil or criminal — and makes them independently actionable as unfair competition. A Labor Code violation, a licensing violation, or a violation of a consumer statute can each anchor a UCL claim even if the borrowed statute provides no private right of action of its own.
- Unfair. The most elastic prong. In disputes between competitors, California courts tether the claim to the antitrust laws: the conduct must threaten an incipient antitrust violation, have effects comparable to such a violation, or otherwise significantly threaten or harm competition. In consumer cases, courts have applied several competing tests, including one that weighs the harm to consumers against the utility of the practice. This prong reaches conduct that is not technically illegal but offends established public policy.
- Fraudulent. Conduct likely to deceive members of the public. This is easier to plead than common-law fraud — no intent to deceive or actual reliance by the public is required — though a named plaintiff alleging deception must still show its own reliance and resulting injury.
Who can sue: the standing gate
Since Proposition 64 (2004), a private UCL plaintiff must have suffered injury in fact and "lost money or property" as a result of the challenged practice. Ideological plaintiffs and uninjured competitors are out. For businesses, this usually means showing diverted sales, lost customers, or money paid because of the practice. Public officials — the Attorney General, district attorneys, and other authorized local officials — can also sue under the UCL and seek civil penalties private parties cannot.
What you can recover — and what you cannot
This is where the UCL surprises people. Private plaintiffs are limited to two remedies:
- Restitution — return of money or property the defendant took from the plaintiff or in which the plaintiff has a vested interest. In Korea Supply Co. v. Lockheed Martin Corp. (2003) 29 Cal.4th 1134, the California Supreme Court held that nonrestitutionary disgorgement — stripping a defendant of profits it did not take from the plaintiff — is not available.
- Injunctive relief — an order stopping the practice, often the real point of a competitor suit.
Compensatory damages, lost profits as damages, and punitive damages are not recoverable under the UCL. There is no jury trial right; UCL claims are equitable and tried to the court. Attorney fees are not automatic either, though a successful plaintiff whose case enforces an important public right may seek fees under Code of Civil Procedure § 1021.5. Because of these limits, the UCL usually travels alongside other claims — false advertising under § 17500, tort claims, contract claims — rather than alone.
The four-year statute of limitations
UCL claims must be brought within four years (Business and Professions Code § 17208). Notably, that period applies even when the borrowed law underlying an "unlawful" prong claim has a shorter limitations period — one reason plaintiffs add a UCL count to revive the practical effect of an otherwise stale theory. Defendants should not assume a UCL claim dies with the underlying claim's deadline.
Defending a 17200 claim
Common pressure points for the defense: attack standing (no lost money or property traceable to the practice), attack the borrowed statute (if the predicate violation fails, the "unlawful" claim fails with it), and attack the remedy (plaintiffs often plead the UCL while actually seeking damages the statute does not allow). Because the claim is equitable, federal courts also generally require plaintiffs to show they lack an adequate remedy at law before obtaining equitable relief — a meaningful hurdle when the same facts support a damages claim. A focused motion early in the case can strip a UCL count down or out entirely, which changes settlement leverage. Our business litigation practice approaches UCL counts with exactly that triage, and businesses worried about their own advertising and sales practices can get ahead of exposure through a compliance review.
