When was a state obligated to follow the Constitution? after all the states had ratified it after that state had ratified it after a majority of states had ratified it as soon as it was written

After that state had ratified it

Explanation:

Even though the Constitution required only 9 out of the original 13 states to ratify it for it to become law, a state was only obligated to follow the Constitution after they had ratified it.

Ratification by a state means that the state has formally approved the Constitution and so by giving this approval, they agree to follow the Constitution and so will be obligated to do so.
