Both New York and Virginia entered the United States with ratification documents that clearly reserved the right of each state to exit the United States.
Are you claiming the ratification documents are invalid?
Both New York and Virginia entered the United States with ratification documents that clearly reserved the right of each state to exit the United States. Both say "to the people", not to the people of NY or VA.
Any reservation of a right to secede would be under natural law, not U.S. law.
