No matter how many times legal experts declare the Patient Protection and Affordable Care Act safe, another lawsuit finds its way into the courts.  

A Wednesday ruling from a federal judge gives PPACA opponents hope that there may in fact be a way to undo — or at least inflict serious harm on —  President Obama's signature domestic policy.

U.S. District Judge Rosemary Collyer, an appointee of President George W. Bush, ruled that Republicans in the House of Representatives have legal standing to pursue the suit, which asserts that some of the money the Obama administration is spending on the law is unconstitutional because it was never authorized by Congress.
