For companies that manufacture or sell products in California, Proposition 65, a law that relates to the disclosure of certain chemicals in products, raises a host of compliance issues and potentially expensive litigation claims. Complying with the law means keeping up with the new amendments and judgments regarding Proposition 65, formally known as the Safe Drinking Water and Toxic Enforcement Act of 1986, that surface every month. To mitigate the risk of pricey Proposition 65 litigation and settlements, clients including manufacturers, distributors and retailers turn to Duane Morris.

Drawing on the resources of an international firm with a national product safety and compliance bench, Duane Morris lawyers experienced with Proposition 65 claims counsel companies, identifying potential exposure, offering informed risk-management audits and tools for compliance and, if necessary, efficiently litigating claims.

While Proposition 65 does not ban the use of any particular chemicals, it does mandate that (1) businesses may not discharge certain chemicals into sources of drinking water, and (2) businesses must provide a "clear and reasonable warning" before exposing people to minute quantities of specified chemicals that are potential carcinogens or reproductive toxins. California published and regularly updates "The List" of chemicals "known to the state to cause cancer or reproductive toxicity"—on the website of the California Office of Environmental Health Hazard Assessment (OEHHA) ( The list currently has more than 800 chemicals and continues to grow.

Proposition 65 can be very costly to businesses selling products in California. The law's unique enforcement scheme, which empowers plaintiffs to file a Proposition 65 lawsuit against a business that fails to provide the requisite warnings and rewards the filer with a share of any penalties resulting from a settlement or judgment, also allows a plaintiff to file suit even if he or she has suffered no harm and has never been to the defendant's premises or used its products. These matters call for an experienced Proposition 65 legal team.
