Now this is an interesting story. Remember Michael Newdow of Elk Grove, California, who challenged the Pledge of Allegiance in the Ninth Circuit on behalf of his public school student daughter, and won? His case is now up for review by the Supreme Court. United States v. Newdow, No. 02-1574.
But, complicating an already complicated case, Newdow wants to represent himself both pro se and pro hac vice -- an extremely rare stance before the high Court. Details (once again) are here from Law.com.
