With the Senate’s February 2, 2011 procedural vote against H.R. 2, which was passed by the House of Representatives on January 19, 2011 to repeal the Patient Protection and Affordable Care Act (PPACA), some members of Congress will be looking for other methods to block the implementation of national health care reform. This timely policy brief from the Robert Wood Johnson Foundation and Health Affairs details what actions members of Congress might take to block or stall the implementation of the PPACA, including repealing specific parts of the law, using a rarely used Congressional authority to block implementing regulations, conduct oversight hearings, and various ways to repeal or withhold funding for implementation of the law.
