In Trust Law, ownership or benefits must vest within a certain time period. This is actually called the “Rule Against Perpetuities.”
Also, Florida state law specifically defines “perpetuity” with a maximum number of years for different issues and circumstances.
Bottom Line...
Did the authors and signers of the Constitution actually have the legal authority to perpetually bind each state to the “United States,” and to use force of arms or economic sanctions to force a rebellious state to stay in the Union?
Congress can call out militia to put down insurrections and enforce statutes.
A state convention to leave the Union is not insurrection.
I’m not a lawyer either. Better than that, we are well-informed citizens.
