The US Supreme Court today rejected a bid by Ohio and other states to stop California from implementing its own clean air rules, a legal right that California has had since the 60s which Donald Trump has repeatedly tried and failed to remove.
Ever since the 1960s, California has been able to set its own clean air rules, as long as they are at least as strict as federal clean air rules. California was granted this waiver in the Clean Air Act as recognition of its unique air quality challenges.
The challenge was brought by Ohio and 16 other republican-led states who sought to end the California’s long-supported state’s right to protect its residents from dirty air. The Courts ruled that the law should stand.
