Reported / Citable
Background
Consumer Protection Group, LLC sued Signal Brands, Ross Stores, and Guess under Proposition 65, alleging that certain clutches and wallets exposed consumers to diisononyl phthalate, or DINP, without the required warning. Proposition 65 permits private parties to act in the public interest after giving government agencies and alleged violators a statutory 60-day notice.
A different private enforcer, CA Citizen Protection Group, had brought an earlier action concerning DINP in Guess cosmetic bags and similar products. That case ended in a court-approved consent judgment whose covered products expressly included Guess clutches and Guess or Nine West wallets. The judgment released warning claims involving DINP exposure from those products. The trial court sustained the defendants’ demurrer without leave to amend, concluding that the prior judgment barred the later suit and that the later plaintiff’s own presuit notices were defective.
The Court’s Holding
The Second District affirmed on claim-preclusion grounds. It held that ordinary res judicata principles apply to court-approved Proposition 65 consent judgments. Although the two enforcement entities were separate, they were in privity because each purported to represent the same public interest in enforcing Proposition 65, rather than vindicating a distinct personal injury.
The later plaintiff argued that the first enforcer lacked authority to bind it because the first 60-day notice named only a cosmetic bag, not the clutch and wallet products. The court rejected that as a basis for collateral attack. The consent judgment itself covered the disputed products, the Attorney General received notice of the proposed settlement, and the approving court entered a final judgment. Any claimed deficiency in the earlier notice did not eliminate that judgment’s preclusive effect in this separate case.
Because the plaintiff did not show that another element of claim preclusion was missing or identify an amendment that could avoid the prior release, dismissal without leave to amend was proper. The court did not decide whether the plaintiff’s own presuit notices independently failed Proposition 65’s requirements.
Key Takeaways
- A court-approved Proposition 65 consent judgment can preclude a later private-enforcement action covering the same products, chemical, defendants, and public interest.
- Separate private enforcers may be in privity because both act as representatives of the public for the claims being prosecuted.
- A later enforcer generally cannot avoid preclusion by collaterally attacking an asserted defect in the first enforcer’s 60-day notice.
- Product definitions and release language in a proposed consent judgment deserve close attention because they may reach beyond the item highlighted in the initiating notice.
- The court left unresolved the separate question whether the later enforcer’s own notices were defective.
Why It Matters
Businesses resolving Proposition 65 claims gain meaningful finality when a consent judgment clearly defines covered products and released claims and is approved through the statutory process. Defense counsel should compare any new demand with prior judgments at the level of product, chemical, exposure theory, and released parties before litigating the merits.
Private enforcers, meanwhile, should investigate existing settlements before serving notices or filing suit. Objections to an earlier settlement’s scope or notice should be raised during that action’s approval process when possible; waiting to challenge the judgment in a duplicative enforcement case may be too late. Settlement counsel should also make the product definitions and release boundaries unmistakable, preserve proof of notice to public prosecutors, and ensure the approval record supports the breadth of relief requested.
