Someone would have to bring a lawsuit. What would that lawsuit be? That elections are unconstitutional? Please. A court can only rule for this side or the other. A legislature can pass any law they fancy and we have to have a judicial body monitoring them.
That's just to get it in front of the court. Once there all sorts of mischievous can be done.
...and we have to have a judicial body monitoring them.
And, who monitors the judicial body?
What we have now is a system of unaccountable jurists who "interpret" the Constitution as they see fit.
