    Arleigh Helfer is an associate in the Litigation Services Department. He is a member of the Appellate Practice Group, the Aviation Group, the Antitrust Group, the Energy and Environmental Group, the Financial Services Practice Group, and the Class Action Group. He concentrates his practice in commercial litigation and has experience in all phases of litigation.

    Mr. Helfer’s litigation practice includes representation of businesses and individuals across a wide range of subject matter. He has a broad range of commercial litigation experience, ranging from antitrust litigation to consumer financial services and products liability class action defense. He has counseled clients concerning effective legal compliance programs and with respect to Hart-Scott-Rodino filings, and assisted in the defense of the Pennsylvania Gaming Control Board’s Philadelphia casino licensing decisions in proceedings before the Supreme Court of Pennsylvania. He has substantial appellate experience and has worked on numerous appellate matters before the U.S. Court of Appeals for the Third Judicial Circuit and Pennsylvania's appellate courts. He has litigated class actions both on the defense and plaintiff side. He has written amicus briefs and assisted with drafting amicus briefs in the Supreme Court of Pennsylvania, the Third Circuit, and the U.S. Supreme Court on civil rights issues of constitutional dimensions and on questions of the preemptive scope of federal law. Mr. Helfer also has represented individuals on a pro bono basis on issues involving civil rights and has assisted civil rights advocacy organizations with such litigation.


    • Mr. Helfer’s pro bono representations focus on civil rights issues. He has represented a young woman whose private school refused to allow her to bring her seizure alert dog to classes and a student who was disciplined by her school for her off-campus speech on social media. He has assisted a prison newspaper with Pennsylvania Right-to-Know Law issues relevant to excessive telecommunications fees assessed to prisoners and their families. He contributed significantly on a pro bono basis to an amicus brief in the Supreme Court of Pennsylvania in the landmark Sixth Amendment case of Kuren v. Luzerne County.
