Morgan Ratner is special counsel in Sullivan & Cromwell’s Litigation Group and is a member of the Firm’s Supreme Court and Appellate Practice.

Prior to joining the Firm, Ms. Ratner served in the Office of the Solicitor General at the U.S. Department of Justice. During her tenure there, she argued eight Supreme Court cases involving areas of federal law such as securities regulation, bankruptcy, employment, intellectual property, criminal law, and elections law. Her recent arguments include Minerva Surgical, Inc. v. Hologic, Inc. (patent validity) and Emulex Corp. v. Varjabedian (private Section 14(e) suits). While at the Solicitor General’s Office, Ms. Ratner also filed over 150 Supreme Court briefs at the merits and certiorari stages.  She received a John Marshall Award, the Department of Justice’s highest award offered to attorneys, for exceptional service to the Office of the Solicitor General and to the Department of Justice.

In private practice, Ms. Ratner regularly briefs and argues appeals and dispositive motions; provides strategic guidance for trial and administrative proceedings; and counsels clients confronting high-stakes legal issues.

After graduating Harvard Law School—where she was awarded the Fay Diploma as the top student in her class—Ms. Ratner clerked for Chief Justice John G. Roberts, Jr. of the U.S. Supreme Court and then-Judge Brett M. Kavanaugh of the U.S. Court of Appeals for the D.C. Circuit. She is a member of the Edward Coke Appellate Inn of Court and is a volunteer with Street Law, Inc.
