This article at CNN.com provides a summary of the 2nd Circuit's ruling on the indefinite, incommunicado detention of U.S. citizen Jose Padilla, alleged gang member, alleged Al-Qaeda training camp trainee, arrested as he got off the plane in Chicago (I think he was returning from his training).
The Bush administration decided to hold Padilla as an "enemy combatant." Eighteen months later, the Courts have decided what was obvious to me all along, that Bush had no authority to just start declaring people to have the status of "enemy combatant."
That sounds reasonable, of course.
Until you realize that the "enemy combatant" category itself is an arbitrary invention of the Bush administration, and a clear violation of the Geneva Convention, a cornerstone of the International Law that Bush pretends does not fucking exist.
UPDATE: The very next day I found this, by Cato, in pdf and html.
