Yup, there is only ONE PLACE in Section 9 that says Habeus Corpus may be suspended (NOT HAVE TO, but MAY BE) in only TWO Cases: Rebellion or Invasion.
NO OTHER PARTS of the Constitution can be suspended. NOWHERE does it talk about having a SHADOW GOVERNMENT to take over if something happens. NOWHERE does it say that ANYONE has power to suspend the entire Constitution. And it could be argued that what is being talked about in Section 9 are things that have to be done in concert between the President AND the majority of Congress, NOT JUST the President.
Were anyone to attempt it, it brings up an interesting legal point. How could it be done, without de-legitimizing the government. It is the Constitution which gives the Federal Government its authority. Suspending it means nullifying their own legal authority, and in essence, publicly declaring that their sole authority is "might makes right"...
