Maureen Mahoney is a partner in the Washington, D.C. office of Latham & Watkins, and leads the firm's appellate and constitutional practice. Ms. Mahoney originally joined the firm in 1980, but left in 1991 to accept an appointment as a United States Deputy Solicitor General. During her tenure in the Solicitor General's Office, President Bush nominated Ms. Mahoney to fill a vacancy on the United States District Court for the Eastern District of Virginia, but the Senate did not act on her nomination prior to the election. Ms. Mahoney returned to the partnership of Latham & Watkins in 1993.

Ms. Mahoney has handled a broad range of constitutional and appellate litigation in the Supreme Court and other courts throughout the country, representing clients as varied as the United States House of Representatives, Union Pacific Railroad Company and the Government of Saudi Arabia. She represented the University of Michigan before the Supreme Court and won the landmark case upholding the constitutionality of admissions programs that consider race as one of many factors in order to attain the educational benefits of a diverse student body. The Legal Times reported that this ruling was a "personal win" for Ms. Mahoney and called her "a skilled appellate advocate, unruffled and poised." The Daily Journal awarded Ms. Mahoney the "Best Oral Argument" in the individual category accolade for that Supreme Court term and went on to say that she "withstood withering questioning from Justice Antonin Scalia while stressing the points relied upon by O'Connor in her opinion for the 5-4 court." In 2005, she successfully argued on behalf of Arthur Andersen in a Supreme Court challenge to the firm's criminal conviction. The Legal Times described the argument in Andersen as "one of the term's best."

Ms. Mahoney argued her first case before the Supreme Court in 1988, when the Court specially selected her to argue a case. She won the case in a 5-4 decision, and the American Lawyer reported that "her presentation was so well-schooled, poised, and disciplined that, according to one justice, the justices passed notes among themselves during the argument praising Mahoney and asking questions about her background." In 1993, Ms. Mahoney successfully defended a highly publicized challenge to U.S. immigration policies. The American Lawyer reported that Ms. Mahoney used "forensic magic" in the argument, and David Broder's Washington Post column called her argument "superb." She also represented the House of Representatives in its successful Supreme Court challenge to the Commerce Department's plans for the use of sampling in the 2000 census.

Ms. Mahoney is a member of the American Academy of Appellate Lawyers and the American College of Trial Lawyers. She has been recognized as one of the leading appellate lawyers by the Legal Times and Chambers USA; the National Law Journal identified her as one of America's top 50 women litigators; and she received the prestigious Rex Lee Advocacy Award from the J. Rueben Clark Law Society. Ms. Mahoney serves as a member of the Advisory Board of The William H. Rehnquist Center on the Constitutional Structures of Government, as a member of the Advisory Committee on Appellate Rules to the United States Judicial Conference, and as a trustee of the Supreme Court Historical Society.

Prior to entering private practice, Ms. Mahoney served as a law clerk to the Honorable William H. Rehnquist (then Associate Justice) and Seventh Circuit Judge Robert Sprecher.
