Officials from 14 states have gone to court to block the historic overhaul of the U.S. health care system that President Barack Obama signed into law Tuesday, arguing that the legislation's requirement that individuals buy health insurance violates the Constitution.
Thirteen of those officials filed suit in a federal court in Pensacola, Florida, minutes after Obama signed the Patient Protection and Affordable Care Act. The complaint calls the act an "unprecedented encroachment on the sovereignty of the states" and asks a judge to block its enforcement.
"The Constitution nowhere authorizes the United States to mandate, either directly or under threat of penalty, that all citizens and legal residents have qualifying health care coverage," the lawsuit states.
The case was filed by Florida Attorney General Bill McCollum and joined by 11 other Republican attorneys general, along with one Democrat. McCollum said the new law also forces states "to do things that are practically impossible to do as a practical matter, and forcing us to do it without giving any resources or money to do it."
McCollum's lawsuit was joined by his counterparts in South Carolina, Nebraska, Texas, Utah, Louisiana, Alabama, Michigan, Pennsylvania, Colorado, Idaho, South Dakota and Washington. Virginia's attorney general, Ken Cuccinelli, filed a separate case in his state Tuesday afternoon.
All but one of those state officials, Louisiana's Buddy Caldwell, are Republicans. But McCollum said the case is "not a partisan issue," and predicted other Democrats would join the suit.
