Getting kind of far out on your twig, aren't you? Congress had their say in the 1790 law and didn't make an exception for secession.
As I pointed out, the New Yorkers who ratified the Constitution believed they had an unabridgeable right that could not be violated to re-assume their own government when their happiness required it. I feel their interpretation is more correct than yours. No offense intended.
The Constitution doesn't say anything about Congress only having one shot to cover all scenerios. It says Congress may prescribe laws for states to prove their acts and their effect. Therefore a state has to allow the Congress to do that.

There's nothing in the Constitution that would say otherwise and I've never said a state doesn't have the right to secede. The Constitution is clear though that the Congress has the right to decide the process of an act being proven, and secession is an act.
