The PSC Nonpartisan COURTs Act establishes a process for citizens to challenge state congressional redistricting plans in federal court if they believe the maps violate the Constitution or federal law. Any state resident can file a lawsuit in federal district court within 30 days after a state finalizes its redistricting plan, with cases heard exclusively in the district court where the state capital is located. When a case involves statewide redistricting claims, a three-judge panel made up of district court judges from within the state must hear the case, and the state's governor and attorney general must receive at least five days' notice. If a court finds that a redistricting plan violates constitutional or federal requirements, it must first give the state an opportunity to propose a corrected plan; if the state does not act quickly enough, the court can impose its own redistricting plan. All cases under this law must be expedited through the court system, with appeals allowed to higher courts including potentially the Supreme Court.
