The Trump administration has asked the Supreme Court to strike down the Affordable Care Act, the landmark health care law that enabled millions of Americans to get insurance coverage. At issue is whether the law’s individual mandate was rendered unconstitutional because Congress reduced the penalty for remaining uninsured to zero and, if so, whether that would bring down the entire law. A federal appeals court last year ruled that the mandate was unconstitutional but punted back to the district court on whether the entire law is invalid or some parts can survive. In a late-night filing, the government’s top lawyer before the Supreme Court argued that once the law’s individual coverage mandate and two key provisions are invalidated, the rest of the law “should not be allowed to remain in effect.” It’s not clear if justices will hear arguments before the November election. This will be the third time the court has heard a significant challenge to the law.
