Smith v. Aichele (2:12-cv-488), Garcia v. 2011 Legislative Reapportionment Commission (2:12-cv-556), and Pileggi v. Aichele (2:12-cv-588) (R. Barclay Surrick, E.D. Pa.)
From January 30 through February 3, 2012, three federal complaints sought to block April 24 primary legislative elections because the district lines were based on the 2000 census. On February 8, the judge denied all requests to delay the primaries. On March 17, 2014, the court of appeals affirmed a judgment against voters because the voters did not reside in districts with legislative seats up for election in 2012.
