A US appeals court on Friday ordered the dismissal of a lawsuit challenging President George W. Bush's domestic spying program, saying the plaintiffs had no standing to sue. The 2-1 ruling by the 6th US Circuit Court of Appeals panel was not on the legality of the surveillance program, but it vacated a 2006 order by a lower court in Detroit. That court had found the post-911 warrant less surveillance aimed at uncovering terrorist activity to be unconstitutional, violating rights to privacy and free speech and the separation of powers. The American Civil Liberties Union led the lawsuit on behalf of other groups including lawyers, journalists and scholars it says have been handicapped in doing their jobs by the government monitoring. The case will be sent back to the US District judge in Michigan for dismissal.
