It was probably around the time period that the States seceded from the Articles of Confederation and Perpetual Union.
This secession was mentioned later in the first legal treatise written after Constitutional Ratification.
And since the seceding states, by establishing a new constitution and form of federal government among themselves, without the consent of the rest, have shown that they consider the right to do so whenever the occasion may, in their opinion require it, as unquestionable, we may infer that that right has not been diminished by any new compact which they may since have entered into, since none could be more solemn or explicit than the first, nor more binding upon the contracting parties. Their obligation, therefore, to preserve the present constitution, is not greater than their former obligations were, to adhere to the articles of confederation; each state possessing the same right of withdrawing itself from the confederacy without the consent of the rest, as any number of them do, or ever did, possess.
