SPRINGFIELD – California’s ability to regulate the pollution limits of cars and light trucks should not be limited by the federal government, Illinois’ top lawyer argued in a joint court filing Friday, because those standards positively affect the health of his constituents. Attorney General Kwame Raoul joined a group of 22 other states, the District of Columbia and two cities in suing the federal government after it moved Thursday to revoke the most populous state’s ability to set stricter emission specifications than those required by President Donald Trump’s Administration. The lawsuit is testing the waters for how federal and state powers will be weighed when setting environmental policies to combat climate change.
