After a 13-year battle that broke new legal ground, the San Francisco City Attorney’s Office and nine other California cities and counties won a historic $1.1 billion judgment against several large manufacturers for aggressively marketing lead paint for indoor use, even long after the companies were aware of its disastrous health consequences for children. In 2017 an appellate court upheld the judgment as applied to over two-thirds of the San Francisco homes affected by lead paint. In 2018, the U.S. Supreme Court declined to hear the companies’ challenge to the judgment against them. SFALP worked on this litigation for over ten years, making it one of the clinic’s longest-running cases. The case has affirmed the breadth of California’s public nuisance law, which is a critical part of the City’s ongling climate change and opioids litigation.
