Habeas Corpus - granted.
Reading the draft Executive Order ordering Guantánamo Bay detention facilities to be closed, one minor paragraph jumped out at me:
(c) The individuals currently detained at Guantánamo have the constitutional privilege of
the writ of habeas corpus. Most of those individuals have filed petitions for a writ of
habeas corpus in Federal court challenging the lawfulness of their detention.
If that was the entirety of the order, it would be a huge step forward for people still imprisoned there - they'll be able to force the government to justify their imprisonment, a right that was consistently denied to David Hicks and the other detainees.
You can read the whole order from a link at the bottom of the ACLU's press release.
