Trying to ensure proportionality in representation... is that the intended goal? Is this even a meaningful pursuit in a bicameral system? The Supreme Court makes rulings that span time infinitely forward, meaning that all those different parties that have existed since the inception of the Union have dissolved and new ones have been formed since, but the rulings of the Supreme Court have not this luxury of death and recycling. Nay, a ruling by the court is very potent and quite a footprint on the legal plain.
So there is no easy way to ensure that a district is Constitutionally Compliant, but we can definitely point out "unconstitutional districting" -- right? Do you agree?
