Shares of health insurers, hospitals, and healthcare companies fell on Dec. 17 in the aftermath of a ruling by a federal judge in Texas that the Affordable Care Act (ACA), commonly called Obamacare, was unconstitutional.
O'Connor agreed with a coalition of Republican officials from 20 states that Obamacare was unconstitutional based on its mandate requiring that Americans obtain medical insurance. The judge refused the states’ request to issue an injunction immediately blocking 2010 law that was championed by Democratic former President Barack Obama from being enforced.
