Congressional and Legislative
Congressional and legislative maps are enacted by the State Legislature. The Governor can veto the plans.
The Legislature can override a veto with a majority vote of all those elected. Republicans currently have veto-proof majorities in both chambers.
Challenges to the maps are litigated in the Montgomery County Circuit Court.
Only the Alabama legislature may refer amendments to the ballot. There is no initiative or referendum process.
