A request by Republican leaders in the Pennsylvania Legislature to stop a new congressional map from being implemented is now in the

hands of the nation's highest court.

The filing made late Wednesday asked Justice Samuel Alito to intervene, saying the state Supreme Court overstepped its authority in

imposing a new map.

More litigation may follow, as Republicans are considering a separate legal challenge in federal court in Harrisburg this week.

The state Supreme Court last month threw out a Republican-crafted map that was considered among the nation's most gerrymandered,

saying the 2011 plan violated the state constitution's guarantee of free and equal elections.

The new map the state justices announced Monday is widely viewed as giving Democrats an edge as they seek to recapture enough U.S.

House seats to reclaim the majority.

House Speaker Mike Turzai and Senate President Pro Tempore Joe Scarnati said the state's highest court made an unprecedented

decision.

"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," they wrote in a filing made electronically after business hours.

The challenge adds uncertainty as candidates are preparing to circulate nominating petitions to get their names on the May primary

ballot.

A spokesman for Democratic Gov. Tom Wolf, responding to the lawmakers' filing, said Wolf was "focused on making sure the Department

of State is fully complying with the court's order by updating their systems and assisting candidates, county election officials and voters

preparing for the primary election."

It is the third time in four months that Turzai and Scarnati have asked the U.S. Supreme Court to put a halt to litigation over the 2011

map they took leading roles in creating.

Alito handles emergency applications from Pennsylvania and the other states covered by the 3rd U.S. Circuit Court of Appeals. Justices

have the authority to deal with these applications on their own, or they can refer the matter to the entire court.

In November, Alito turned down a request for a stay of a federal lawsuit, a case that Turzai and Scarnati won in January.
