A three judge panel with two Republicans and one Democrat hearing the suit just ruled that those states that did not establish a state exchange, 36 in all including NC, are not eligible for premium subsidies for their health insurance. The vote was 2-1 with both Republicans voting to ban the subsidies, those judges were appointed by Bush I and Bush II.
This means that those people who are covered under the Affordable Care Act and are receiving a discounted premium rate will see those subsidies disappear in the future.
The decision will be appealed to the full DC Court of Appeals. Should it be upheld, it would probably take the election of a Democratic governor in 2016 and the approval of a state health exchange in North Carolina for those presently covered and those covered in the future to get their subsidies back.
