HARRISBURG — A new legal filing claims redrawn district maps for the state House of Representatives improperly carves up Butler County.

The lawsuit docketed on Tuesday focuses on changes made to Butler County in district lines approved by the Legislative Reapportionment Commission earlier this month.

The plaintiffs are Darlene Covert, her son, Ryan Covert, and a third Butler resident, Erik Hulick. The reapportionment commission is the defendant.

People have about two weeks left to take their objections to the General Assembly maps to the state Supreme Court. Additional challenges are expected, including from state House Majority Leader Kerry Benninghoff, a Centre County Republican.

Benninghoff cast the lone “no” vote when the Legislative Reapportionment Commission approved the revised maps by a 4-1 vote.

The lawsuit notes Butler County was divided into three legislative districts under the preliminary House map advanced in December, but the final map approved Feb. 4 split it into four districts.

The plaintiffs claim the final House map makes Butler County residents “victims of excessive partisan or political classifications and other circumstances orchestrated to protect incumbent state representatives.”

“This redistricting unconstitutionally divided Butler County, its municipal boundaries, school districts and other logical boundaries resulting in political gerrymandering to the detriment of Butler County residents,” a statement from Covert’s Butler attorneys reads.

It calls the House map an unconstitutional political gerrymander.
