They say they'll petition the U.S. Supreme Court this week to halt the decision.
In a decision that could tilt the congressional balance of power in a key swing state in favor of Democrats, Pennsylvania's highest court decided the state's congressional districts violate its constitution and ordered the lines of all 18 redrawn in the next few weeks.
The court gave the General Assembly - which remains under Republican control - until February 9 to submit redrawn lines to Gov. Tom Wolf - a Democrat - who must approve the plan no later than February 15.
The state Senate president, Joe Scarnati, and majority leader, Jake Corman, both Republicans, called the court's deadline for a new map "impossible" and said they would request a stay from the US Supreme Court.
The court said the boundaries "clearly, plainly and palpably" violate the state's constitution, and blocked them from remaining in effect for the 2018 elections.
As Stephen Wolf of Daily Kos notes, a new nonpartisan congressional map in Pennsylvania could give Democrats anywhere between one and six more House seats, significantly improving the odds of Democrats winning the entire chamber.

It is expected that the new map for the 16th District, now held by Rep. Lloyd Smucker, will likely stay similar or get a few additional Republican voters - likely returning to a more familiar shape seen prior to 2011. "I want to thank and compliment the attorneys and parties who brought this before the Supreme Court and helped right this obvious wrong". District courts typically have been loathe to step into cases and rulings based on state Constitutions unless they are seen to violate the U.S. Constitution.
"It shows there may be a second front in the war against gerrymandering that does not depend on what the U.S. Supreme Court does or does not do in the Wisconsin and Maryland cases", Li said.
The ruling comes the same month a three-judge federal panel ruled that North Carolina's congressional map is unconstitutional because it was drawn primarily with political motives in mind. On a new map, however, it could become much more Democratic-leaning.
The March special election for a vacant U.S. House seat in western Pennsylvania is not affected, the court said. The court said in its order that that race will proceed under the old congressional map.
The League of Women Voters had challenged the district map in court, arguing that the state's congressional lines were "among the most extreme partisan gerrymanders in American history".
