A US appeals court has thrown out a lawsuit against Vice President Dick Cheney. The suit sought details about Vice President Dick Cheney’s 2001 energy policy task force that formed policy favorable to the industry. The unanimous ruling ordered a federal judge to dismiss the lawsuit by the Sierra Club environmental group and the watchgroup Judicial Watch. The dismissal of the case had been expected after a U.S. Supreme Court ruling in June last year that refused to require that task force records be disclosed. It sent the case back to the appeals court.
