A federal judge in Virginia has struck down the Obama administration's requirement that all Americans buy health insurance, a key provision in the landmark health care bill that the president signed in March.
Today's ruling could undercut the entire health care plan, though U.S. District Judge Henry Hudson wrote that his decision will surely be appealed -- probably all the way to the U.S. Supreme Court.
Hudson ruled that the individual mandate "exceeds the constitutional boundaries of congressional power." He added that he won't stop implementation of the law as various challenges wind their way through the courts, noting that many provisions won't take effect until at least 2014.
