The California Court of Appeal affirmed a lower court's decision to dismiss a lawsuit filed by Consumer Protection Group, LLC (CPG) against Signal Brands, LLC, Ross Stores, Inc., and Guess ?, Inc. The case, docketed as B345531, involved claims under California's Proposition 65, which mandates warnings for products containing harmful chemicals. The ruling affects consumers and advocates concerned about chemical exposure and product safety.
CPG alleged that the defendants failed to warn consumers about exposure to Diisononyl phthalate (DINP) in certain clutch and wallet products. The trial court dismissed the case after sustaining a demurrer, citing two main reasons: the res judicata effect of a prior settlement involving a different private enforcer and defects in CPG's presuit notices.
In the dispute, CPG contended that it was not in privity with the California Citizen Protection Group, LLC (CCPG), which had previously settled a similar Proposition 65 claim involving the same products. CPG argued that since CCPG's notice only identified a cosmetic bag and not the clutch and wallet, it should not be bound by the earlier settlement. The case reached the California Court of Appeal after CPG's initial complaint was dismissed, and it was granted leave to amend, but the amended complaint was also dismissed without leave to amend.
In its ruling, the court upheld the trial court's decision, stating, "CPG is in privity with CCPG because they both purport to represent the public interest." The court emphasized that common-law res judicata principles apply to Proposition 65 consent judgments, effectively barring CPG's claims. The ruling noted that even if the prior judgment was erroneous, it still held res judicata effect.
The court also addressed CPG's argument regarding the adequacy of its presuit notices, which the trial court found to be defective due to improper contact information. However, the appellate court did not need to rule on this issue since the res judicata claim was sufficient to affirm the dismissal.
This ruling has significant implications for private enforcers of Proposition 65 and consumers. It reinforces the idea that once a settlement is reached in a Proposition 65 case, it can prevent subsequent claims on similar grounds, even if the new enforcer did not participate in the original case. This could discourage new lawsuits aimed at enforcing consumer safety standards under Proposition 65.
Moving forward, the ruling sets a precedent that may limit the ability of private enforcers to bring new claims if a prior settlement exists, potentially impacting how Proposition 65 is enforced. CPG may seek to appeal the decision to a higher court, but details on any potential appeal were not available in the court filing.
