On the first read, that sentence does not even make sense to me. I'm going to have to parse it apart to figure out what you are attempting to say. Perhaps you could simply put your point into a clearer form?
By the way, if it is of any interest to you, the Supreme Court ruled that unilateral secession was unconstitutional their 1869 ruling in Texas v. White.
No, I don't care too much about Supreme Court rulings made by picked judges from one side of an issue. Maybe they have employed good reasoning in their decision, but from observation I can tell that decisions are usually based on the political preferences of the judges involved, and not so much on actual facts.
