HARRISBURG — Pennsylvania’s highest court overstepped its authority in drawing new congressional district lines and did not give state lawmakers enough time to produce a map of their own, eight Republican congressmen said in a lawsuit filed Thursday.

The complaint in Harrisburg federal court argued against the legality of the map put in place Monday by the state Supreme Court, and said a 2011 Republican-crafted map should remain in use this year.

The plaintiffs, which include U.S. Rep. Mike Kelly, R-3rd, are suing the top elections official under Democratic Gov. Tom Wolf, asking for an injunction to prevent the Department of State from implementing the new plan.

“Far from being free of politics, it appears every choice in the court drawn plan was to pack Republicans into as few districts as possible, while advantaging Democrats,” the plaintiffs alleged.

A separate legal challenge to the new map by two senior Republican legislative leaders is currently awaiting action by the U.S. Supreme Court.

A spokesman for Wolf said he and the elections agency “are complying with the court’s order to implement the remedial map and assuring the commonwealth is prepared for the primary election.”

The 2011 map is widely considered among the nation’s most gerrymandered, a mélange of jagged lines and odd shapes that include one likened to the cartoon character Goofy kicking Donald Duck. The 2011 map, in some places, narrows to the width of a single property.

It has proved to be a political winner for the GOP, helping the party maintain a 13-5 edge in the state’s congressional delegation over three straight election cycles.

An analysis conducted through PlanScore.org concluded the state court’s redrawn map would eliminate “much of the partisan skew” favoring Republicans on the old GOP-drawn map, but not all of it. Democrats hope a new map in Pennsylvania will help them retake majority control of the U.S. House this year. Six congressional seats are or will be vacant in Pennsylvania, an unusually large number that has helped draw a slew of would-be candidates.

The plaintiffs include seven Republican members of Congress who are expected to seek re-election: Kelly, along with Reps. Ryan Costello, Tom Marino, Scott Perry, Keith Rothfus, Lloyd Smucker and Glenn Thompson; as well as U.S. Rep. Lou Barletta, running for U.S. Senate; state Senate Majority Leader Jake Corman; and state Sen. Mike Folmer, chair of the State Government Committee.

Not among them is U.S. Rep. Brian Fitzpatrick, a Republican from the Philadelphia suburbs who wants to turn over redistricting to an independent, non-partisan commission.

The federal lawsuit was filed the day after House Speaker Mike Turzai and Senate President Pro Tempore Joe Scarnati, the top Republican leaders, asked the U.S. Supreme Court to stop the court-ordered map from being implemented. Some of the same lawyers worked on both filings, and the approaches are notably similar.

“The Pennsylvania Supreme Court conspicuously seized the redistricting process and prevented any meaningful ability for the Legislature to enact a remedial map to ensure a court drawn map,” lawyers for Scarnati and Turzai wrote.

In throwing out the 2011 map in January, all five Democrats on the state Supreme Court sided with Democratic voters who challenged the map, saying it ran afoul of the state constitution.
