Attorney General Curtis Hill argued in a brief filed this month that the cities of San Francisco and Oakland should not be able to use the common law of “public nuisance” to force five fossil fuel companies to pay for the harms the cities say the companies created by contributing to global climate change. Leading an 18-state coalition, Indiana filed its amicus brief on May 17. In the brief, Attorney General Hill urged the Ninth Circuit of the U.S. Court of Appeals to dismiss the lawsuit filed by the State of California on behalf of the two cities against the five named companies.
