The U.S. Supreme Court agreed to consider a challenge to the subsidies that are a linchpin of President Barack Obama’s health-care overhaul, accepting a case that suddenly puts the law under a new legal cloud. Two years after upholding much of the law by a single vote, the justices today said they will hear a Republican-backed appeal targeting tax credits that have helped more than 4 million people afford insurance.A ruling blocking those credits might unravel the Affordable Care Act, making other provisions ineffective and potentially destabilizing insurance markets in much of the country. The high court’s decision to hear the case comes days before the start of the law’s second open-enrollment season. A decision will come by June.- Bloomberg
