Advising on compliance and defending Proposition 65 claims

Advising on and defending Proposition 65 claims are a key aspect of our integrated product safety, compliance and recall practice. For decades, we’ve advised food, beverage, manufacturing and consumer product companies on Prop 65 matters, including high profile claims that threaten brands and nuisance claims that impact on profitability.

Officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, we help to resolve Prop 65 legal matters in line with your commercial goals. We provide counsel and advocacy to manufacturers, distributors and retailers across almost every product line, particularly in food and beverages.

Our involvement in delivering successful legal strategies for key litigations and settlements underlines our capability.

In the first instance, we can help you to reduce Prop 65 risk through strong compliance programs firmly grounded in the law, supporting and not hindering operational needs and industry requirements. This is about achieving compliance without disrupting your business. Programs can start in the R&D stage, with our team bringing experience throughout the development cycle.

Our advice draws on wide experience in areas including supply chain dynamics, negotiating and drafting terms for upstream suppliers, and downstream distributors.

“We couple confident advocacy with technical fluency in specific areas such as product chemistry, testing methodologies, and exposure analysis”

We also work to solve enforcement actions before they grow into serious problems or penalties. When complicated claims arise, we’re at the forefront of addressing such matters based on an up-to-date understanding of the Act’s workings, new plaintiff theories, and the expanding chemicals list. We also leverage strong industry relationships to your advantage. This can include liaising with the State Attorney General's Proposition 65 Enforcement Division lawyers.

We couple confident advocacy with technical fluency in specific areas such as product chemistry, testing methodologies, and exposure analysis. Our approach is to develop creative and cost-effective litigation defenses aimed at withdrawal of claims, a win in court, or favorable settlement.

Our work can include helping you to protect safe product lines from claimants who consistently look for new opportunities to attack, in areas such as dietary metals and acrylamide, furfuryl alcohol, and fluorinated compounds like PFOS and PFOA. We’re also well versed in plaintiff bar tactics that can involve private party litigation.
