"What part of the Constitution prevents secession? What federal law made in PURSUANCE of the Constitution prevents secession?"
Yes, there you have it. The suicide pact thesis. It's a silly thesis now, but to try that thesis in the time of the Founding - after a weak Art. of Confederation failed so miserably - is just plain sophmoric.
That argument may be bought to a radical bent on an agenda, but it won't be bought by any serious student of the Constitution or history.

So in others words, you CAN'T cite any section of the Constitution that prevents secession.
