The U.S. Department of Justice has signed off on maps redrawing Louisiana’s congressional and Public Service Commission election districts.

The state Attorney General’s office received word late Monday via an email notice on the deadline for a decision, spokeswoman Amanda Larkins said.

The congressional plan calls for six districts — one less than exists currently — which caused a lot of political jockeying in the Louisiana Legislature as various factions tried to protect their home bases.

Louisiana lost a congressional district seat because its population did not grow enough to keep it. The state suffered population losses in the wake of Hurricane Katrina in the New Orleans area.

The state must redraw the districts every 10 years based on the population shifts since the last census.

Neither the new congressional nor the PSC election districts will be used in fall elections. Elections with the new lines will not occur until 2012.
