The high court on Monday refused to block a federal judge's October 2009 ruling that required California lawyer and dentist Orly Taitz to pay the $20,000 fine for filing a "frivolous" litigation. The judge said Taitz attempted to misuse the federal courts to push a political agenda.
Taitz sued in Georgia federal court on behalf of Army Capt. Connie Rhodes. Rhodes sought to avoid deployment to Iraq by claiming Obama wasn't born in the United States.
Justice Samuel Alito on Monday rejected Taitz's second request to block the sanctions. Justice Clarence Thomas had rejected the request earlier.
