In a split decision, the California Supreme Court on Wednesday declined to review a state appeals court ruling against major manufacturers of lead paint that held them liable for hundreds of millions of dollars in remediation costs to remove the dangerous product from homes.

The decision leaves in place a ruling by the Sixth District Court of Appeals last November, which concluded that Sherwin-Williams Co., NL Industries Inc. and ConAgra Grocery Products Co. “must have known” that lead paint posed a risk of serious harm to children even while they promoted its sale.
