In a notice dated Wednesday, the Justice Department listed 196 pending habeas cases, some of which cover groups of detainees. The new Military Commissions Act (MCA), it said, provides that "no court, justice, or judge" can consider those petitions or other actions related to treatment or imprisonment filed by anyone designated as an enemy combatant, now or in the future.

The relevant section from Section 9 of Article 1 of the Constitution:

The privilege of the Writ of Habeas Corpus shall not be suspended, unless when in Cases of Rebellion or Invasion the public Safety may require it.

No Bill of Attainder or ex post facto Law shall be passed.

It seems to me that the two positions are in direct opposition, on multiple grounds, and when that is the case, the Constitution wins.

Nice try, but this one don't fly Il Dupe. It's called "Violating the Oath of Office," and it means, "move back to Crawford you piece of crap."
