The court-mandated map was set to apply beginning with the primary elections on May 15, 2018.  Republican lawmakers in the state asked for a stay from the United States Supreme Court and brought suit in federal court, seeking an injunction against using the court-drawn map in the upcoming congressional elections. Both attempts failed on March 19, 2018, following rulings by the Supreme Court and a Pennsylvania federal district court.
