The region map- which doesn't have 10 states each- was approved in the same voting where the Constitution was approved- the Constitution which clearly states that each region has 10 states.
In other words, the voters have approved contradictary proposals. In my opinion, the vote for the Constitution supercedes the vote for which map to use.
If you go ahead with this map for regions, then the clause in the section stating regions have 10 states each needs to be re-written. (I guess the Constitution needs to be re-written, anyway.)
Perhaps the voters did not clearly understand they were voting for a map which would not give an equal number of states to each region (since they also voted for a Constitution that said otherwise). If this applies to you, please speak up.
Have you all noticed I'm a stickler for procedural detail?
