On Friday the U.S. House of Representatives filed a federal lawsuit challenging several aspects of how the Obama administration has implemented the 2010 Affordable Care Act. You can read the plaintiffs’ full case here (pdf) against two cabinet secretaries and the agencies they lead. The main arguments are that the Obama administration broke the law by delaying the employer mandate to provide health insurance, and also by providing certain payments to health insurance companies without having Congress appropriate those funds. The first point was expected, but the second argument surprised even those who have closely followed the political battle over Obamacare. Sarah Kliff explained the challenged payments and how they fit into the law. Ashley Parker reported for the New York Times, “If the lawsuit is successful, poor people would not lose their health care, because the insurance companies would still be required to provide coverage – but without the help of the government subsidy, the companies might be forced to raise costs elsewhere.”

In contrast, the legal challenge to delaying the employer mandate is more “symbolic,” as that provision of the Affordable Care Act will have gone into effect by the time this lawsuit works its way through federal courts.

House Republicans voted to authorize this lawsuit shortly before going on a long summer recess. Iowa’s four representatives split on party lines, with Republicans Tom Latham (IA-03) and Steve King (IA-04) supporting the measure and Bruce Braley (IA-01) and Dave Loebsack (IA-02) opposed, along with every other House Democrat present. At the time, the lawsuit was perceived as House Speaker John Boehner’s way of deflecting conservative sentiment toward drafting articles of impeachment. At times this fall, Congress-watchers wondered whether the lawsuit would go forward, as two major law firms worked on the case for a while before declining to participate in litigation. A conservative legal scholar eventually took the case.
