Procedural problem could derail Obamacare lawsuit

Could the latest high-stakes challenge to Obamacare be stumbling just short of the goal line? For the last two years, four challengers have waged a pitched battle with the Obama administration over whether the Affordable Care Act authorizes subsidies that make insurance affordable for millions of people. The stakes are huge: Without the subsidies, more than 8 million Americans would lose their insurance. The case, King v. Burwell, has reached the doors of the Supreme Court. Yet now, just weeks before the much-anticipated oral argument, questions suddenly have surfaced about whether the challengers can be in court at all.
