A Texas doctor sued the U.S. over President Barack Obama's health-care reforms on claims the U.S. Supreme Court overlooked when it upheld the Affordable Care Act last year. Steven Hotze of Houston claims the law, the Patient Protection and Affordable Care Act, violates the U.S. Constitution's origination and takings clauses, which weren't part of arguments before the Supreme Court. The high court upheld the act by a 5-to-4 vote. Hotze's suit, filed today in federal court in Houston, targets the "shared responsibility payment" business owners will be required to pay the U.S. under the act if they choose not to provide government-approved minimum health coverage for their workers. That penalty kicks in on Jan. 1.
