A panel of three federal judges is set to hear closing arguments in a civil suit brought by Republican voters who claim the state's new legislative maps were drawn up to give Democrats a better chance of winning seats in the state Legislature.
The weeklong trial wraps up Friday in U.S. District Court in Phoenix.
Lawyers for the GOP voters are trying to prove the two Democrats and one Independent on the commission froze out the two Republicans.
Lawyers for the Arizona Independent Redistricting Commission deny the majority that drew maps for Arizona's 30 legislative districts did anything wrong.
The judges have been hearing testimony since Monday from commission members, mapping consultants and political operatives who spoke with commissioners while they were drawing the maps they adopted in January 2012.
