If I recall correctly, secession within a state requires the approval of the state involved and the U.S. Congress.
So the state of New York and Congress would have to approve of seceding from New York City. That would be tough to do legislatively.
Anyone please correct me if the process is different. As a practical matter, hasn’t happened since West Virginia split from Virginia during the Civil War.
Figgerd that.
In today’s language, tho, it comes to money. Can a municipality, today, tell the State (and by extension the Feds), ^Molon Labe^ when it comes to collecting taxes.
If not, well, the tax-paying citzens gets what they voted for, yes?
