What will the Justice Department say?

What will the Justice Department say about a Dallas City Council Redistricting map they must approve that does not follow the guidelines passed by that same Dallas City Council? What will the Justice Department say when it is obvious there are other maps that provide a more complete minority representation, with more compact, less gerrymandered district lines?

Gerrymandering is mandatory if you want to design districts that will continue to produce an Anglo majority city council in a town with a population that is over 71% minority.

(The above comment was left under the 6th Dallas Morning News editorial urging the Dallas City Council to approve a less gerrymandered map for Dallas.)
