The U.S. Supreme Court has declined to grant cert for a petition filed by Johnson & Johnson on behalf of its Ethicon subsidiary to review a case in California that will cost the company more than $300 million. The outcome highlights the differential hazards of advertising and promotion in various U.S. states, with California state law allowing fines of up to $2,500 for each violation of state law, an amount that can quickly tally into the hundreds of millions.
