For the past two years, the American Civil Liberties Union (ACLU) has been challenging the US government’s No-Fly List. It has raised objection to the secrecy surrounding the list and the fact that people, who are on the list, are typically not told why their name is on the list. The government also does not give those on the list a fair opportunity to have their name removed.

Now, the ACLU is taking a case against the government before a federal appeals court.
