US federal judge has ruled the Affordable Care Act (ACA) or Obamacare as unconstitutional due to a recent change in federal tax law. The ruling on Friday night by US District Judge Reed O'Connor of Texas overturns all of the 2010 healthcare law nationwide.

In his opinion, Judge O'Connor said: "(The) individual mandate can no longer be fairly read as an exercise of Congress's Tax Power and is still impermissible under the Interstate Commerce Clause-meaning the Individual Mandate is unconstitutional." He also held that the individual mandate is "essential to and inseverable from the remainder of the ACA".
