Supreme Court and Appellate Litigation

Recognized nationally as a rising star in the Supreme Court and appellate bar, Parker Rider-Longmaid has significant argument and briefing experience before federal and state appellate and trial courts across the United States. He has argued before the Supreme Court and the Second, Fourth, Seventh, and Ninth Circuits and led briefing and strategy in the Supreme Court and all of the federal circuit courts of appeals. In Reed v. Goertz, No. 21-442, 143 S. Ct. 955 (2023), Mr. Rider-Longmaid led a team from Skadden, the Innocence Project, and other firms to secure a U.S. Supreme Court victory for longtime pro bono client Rodney Reed, a Texas death-row inmate who has steadfastly maintained his innocence for more than two decades. Mr. Rider-Longmaid argued the case, his first before the Supreme Court, in October 2022, after convincing the Court to grant review in April 2022. In April 2023, the Court sided with Mr. Reed, reversing the Fifth Circuit and holding that his 42 U.S.C. § 1983 suit seeking DNA testing of crime-scene evidence was timely. The decision has significant ramifications for inmates with innocence claims seeking access to DNA testing. Reed was one of four Supreme Court merits cases that Skadden’s Supreme Court and Appellate Practice briefed and argued during the Court’s 2022 Term — more than almost any other law firm. Mr. Rider-Longmaid helped guide strategy and lead drafting in each of those cases. He also helped convince the Court to grant review in two cases for the October 2023 Term and one case for the upcoming October 2024 Term. Beyond the Supreme Court, Mr. Rider-Longmaid also plays leading roles in the Practice’s major matters before the federal courts of appeals. His work ranges from constitutional and administrative law to tax, preemption, arbitration, antitrust, bankruptcy, class-certification, and employment, as well as federal Indian law, criminal defense and habeas corpus, and voting rights. Mr. Rider-Longmaid maintains an active pro bono practice, representing clients in criminal, habeas, immigration, and constitutional cases at all levels of the federal courts. For example, he secured a Fourth Circuit win for a defendant erroneously sentenced as a career offender, United States v. Cannady, 63 F.4th 259 (4th Cir. 2023), and habeas relief for a client whose criminal defense attorney failed to provide him with the effective assistance of counsel guaranteed by the Sixth Amendment, Cook v. Foster, 948 F.3d 896 (7th Cir. 2020), following oral arguments in which judges praised his advocacy.
