Two Texans backed by a conservative legal group have filed a federal lawsuit in Austin challenging how state Senate voting districts were drawn.
The Austin American-Statesman reports the Project on Fair Representation wants a judge to cancel results of the March primaries, which used Senate boundaries drawn by the Legislature in 2013.
The group wants Texas lawmakers to draw new districts. The plaintiffs are voters in two Senate districts -- Tyler and Houston areas.
The case filed Monday argues the way districts were drawn is unconstitutional for being based on total population. The suit says only eligible voters should be considered.
The group's director, Ed Blum, helped lead the Fisher vs. University of Texas affirmative action case challenging using race in university admissions heard by the U.S. Supreme Court.
