By David Morgan and Aruna Viswanatha WASHINGTON (Reuters) - A U.S. federal judicial panel on Tuesday dealt a potentially devastating blow to President Barack Obama's healthcare law, throwing out a provision that provides millions of Americans with subsidies for private health insurance. The 2-1 decision, which could lead to a new showdown over Obamacare before the U.S. Supreme Court, would prevent the administration from offering premium tax credits to people who purchase insurance through the federal insurance marketplace that serves most of the 8 million consumers who have signed up for private coverage for 2014. The judges from the U.S. Court of Appeals for the District of Columbia stayed the ruling to allow for an appeal. The Obama administration said it would appeal to the full circuit court, a process that could take up to six months, and stressed the ruling would have no impact on consumers receiving monthly subsidies now.
