Let me see... The Union of Soviet Socialist Republics had a Constitution. A very good one, in fact - quite similar to the United States Constitution (the only _major_ difference was that it allowed the "member states" to secede).
Of course, this Constitution, too, was quite "dysfunctional." It did not allow Josef Stalin to do "what needed to be done" - so he circumvented it. Starving millions of Kulaks in the Ukraine, forced labor on "Hero Projects" by Gulag inmates, splitting Poland with Nazi Germany - all unconstitutional.
But of course, all of this needed to be done for "progress." Coming soon to your own back yard.
