Veteran appellate advocate Shay Dvoretzky is leaving Jones Day to join Skadden, Arps, Slate, Meagher & Flom, where he will begin and lead a U.S. Supreme Court and appellate litigation group.

Dvoretzky has argued 12 cases in the Supreme Court and many more in federal and state courts. He will be a partner in Skadden’s Washington office. David Zornow, global head of Skadden’s litigation practice, said Dvoretzky is “recognized as among an elite group of Supreme Court advocates.”
