AUSTIN, Texas (Legal Newsline) – On Monday, the Project on Fair Representation announced the filing of a federal lawsuit challenging the constitutionality of Texas’ state Senate districts.

The plaintiffs in this case, Sue Evenwel and Edward Pfenninger, are registered voters in Texas Senate Districts 1 and 4. They assert that Plan S172 — the Texas Senate redistricting plan enacted by the legislature and signed into law by Gov. Rick Perry on June 26, 2013 — is unconstitutional under the 14^th Amendment to the U.S. Constitution.
