Maybe because it’s because the lack of a Constitution makes it easier for these lawyers to rape, loot & pillage when they pass the bar?
A student who graduates from Yale Law School might only be able to apply to the bar in Connecticut, and be limited to practicing in Connecticut unless there is a reciprocal arrangement between Connecticut and another state in a post-Constitutional union.
Furthermore, the laws that the student learned in school might no longer apply, since it would be the Constitution of Connecticut that would govern from now on, making the students' knowledge and training moo (you know, a cow's opinion).
