1. There was some very aggressive (illegal in my view) incorporation by Baton Rouge.
2. Then there was the exclusion of areas that did not want to be a party to the new city in the prior vote.
There is the City of Baton Rouge
There is the Parish of Baton Rouge.
The parish has an unusual system where the City and the Parish are run by the same people.
I believe there are currently five incorporated areas in the Parish of Baton Rouge.
Such as the City of Central.
So they are NOT breaking away from the Parish of Baton Rouge. They will still be in the Parish.
They are making their own City within this Parish.
This whole fight was about forming an independent school district. The Parish refused them that right, and told them they had to incorporate to separate the school system.
