CARTER G. PHILLIPS is one of the most experienced Supreme Court and appellate lawyers in the country. Since joining Sidley, Carter has argued 79 cases before the Supreme Court, more than any other lawyer in private practice. Prior to joining Sidley, Carter served as an Assistant to the Solicitor General and in that position he argued nine cases before the Supreme Court on behalf of the United States Government. He thus currently has a total of 88 oral arguments before the Supreme Court and more than 140 arguments before the United States Courts of Appeals. He has argued in every Circuit and has argued more than 35 cases before the United States Court of Appeals for the Federal Circuit. At the outset of his career, Carter clerked for Judge Robert Sprecher on the United States Court of Appeals for the Seventh Circuit and for Chief Justice Warren E. Burger on the United States Supreme Court.
Carter was the managing partner of Sidley’s Washington office and a member of the firm’s Management and Executive Committees from 1994 until 2013. He then became the Chair of the firm’s Executive Committee and served in that role until 2018 when he became the Chair Emeritus. Since then he has returned to the full-time practice of law along with serving as the co-director of Northwestern University School of Law’s Supreme Court Clinic.
Carter’s advocacy on behalf of clients has earned him acknowledgement in numerous publications. An academic study of Supreme Court briefs from 1946 to 2013 found Carter to be one of the most successful lawyers to argue in front of the Supreme Court. The analysis, “Who Wins in the Supreme Court? An Examination of Attorney and Law Firm Influence,” led the author to conclude that “not only is Phillips a seasoned Supreme Court litigator, but he is also one of the most successful Supreme Court brief-writers.”
In recognition of Carter’s litigation success, he has been ranked among the nation’s top lawyers by Chambers USA, The Legal 500 United States, Benchmark Litigation, The Best Lawyers in America, Who’s Who Legal and the National Law Journal. He consistently is recognized by Chambers USA as being in the nation’s top tier of appellate lawyers and regularly receives the directory’s highest level “Star” ranking. That publication said that Carter is “one of the leading lights of the appellate Bar, described as ‘a truly unique talent’ whose incredible expertise sees him appear frequently before the Supreme Court.” Over the years, sources have told Chambers that he is “in a league of his own” with “a CV that stretches from the U.S. to London,” noting especially that he “enjoys a lot of credibility with the Supreme Court and has an amazing track record,” and that “there’s nobody quite like him on an appellate issue.” Benchmark Litigation also names Carter a “Litigation Star,” calling him “a household name” in the appellate world.
