An anonymous reader writes "In February, Judge William Alsup ruled in favor of Rahinah Ibrahim, who sued the U.S. government in 2006 after she was mistakenly added to the no-fly list and subsequently denied entry to the country. Now, the Department of Justice has finally decided it won't appeal the ruling, making Ibrahim the first person to challenge the list at trial and get herself removed. 'But Ibrahim's case, as just one of hundreds of thousands of individuals who have been placed on such lists, shows the system's opacity. First, the only surefire way to even determine if one is on such a list in the U.S. is to attempt to board a flight and be denied. Even after that happens, when a denied person inquires about his or her status, the likely response will be that the government "can neither confirm nor deny" the placement on such lists. The government's surrender in Ibrahim comes on the heels of a new report by the American Civil Liberties Union that shows just how insanely difficult it is to contest one's status on the government blacklists (PDF).'"
