Ms. Prewitt is a first-chair trial counsel and two-time recipient of the Attorney General’s Distinguished Service Award (the DOJ’s second highest award) and the Assistant Attorney General’s Award.

Ms. Prewitt is known as a preeminent competition lawyer and has been recognized internationally by leading publications, including as a “leading lawyer” by Global Competition Review; Expert Guides: Business Law and Competition; Who’s Who Legal: Competition recognizing her as “one of the leading cartel lawyers in the US” who is praised as a “talented criminal antitrust lawyer with strong presence;” Lawdragon recognizes her as one of 500 Leading Litigators in America; The Legal 500, recognizing her for being “exceptionally knowledgeable, commercial, user-friendly and responsive;” and Chambers USA, with sources describing her as an “expert in antitrust law” and “very smart, very strategic and very user-friendly.” Most recently, Ms. Prewitt was the winner of the US Behavioral Matter of the Year award by GCR for successfully defending a poultry executive facing a criminal price fixing charge by the DOJ, serving as first-chair trial counsel over the course of 13 weeks prior to its dismissal with prejudice.

Ms. Prewitt is Co-Chair of the International Bar Association Antitrust Section’s Cartel Working Group and Vice-Chair of the Programs Committee of the American Bar Association’s Antitrust Section, and was elected as a Fellow of the American Bar Foundation and the David E. Rockefeller Foundation.

Ms. Prewitt’s experience includes representing a:

  • Poultry industry executive facing a criminal cartel conspiracy charge filed by the Antitrust Division of the Department of Justice for fixing prices and rigging bids for broiler-chicken products over an 8-year period. Throughout a seven-week trial in Denver in the fall of 2021, leading to a hung jury with nine votes to acquit, and then a six-week trial during the spring of 2022 resulting in another hung jury, the Latham team put up an aggressive defense to the government’s case and proved that our client had neither motive nor means to fix prices. The Antitrust Division then dropped the case against our client and four others with prejudice, earning our team top honors as AmLaw’s Litigator of the Week.
