Judith A. Zahid

Judith A. Zahid is a commercial litigator focusing on antitrust and complex litigation and a Managing Partner of Zelle Hofmann’s San Francisco office. 

Judith has substantial experience representing clients pursuing high-stakes price-fixing and monopolization claims arising out of global markets. Such representative plaintiff matters include serving on the lead counsel team for In re TFT-LCD (Flat Panel) Antitrust Litigation (MDL No. 1827)—which culminated in a record-breaking $1.082 billion all-cash settlement for the end-user plaintiffs, in one of the nation’s largest antitrust cartel cases.  

On the defense side, Judith has represented companies in the energy and retail markets against price-discrimination claims, leading to favorable and cost-effective resolutions for her clients. 

Judith’s professional experience mirrors what the most cutting-edge antitrust cases look like today:  international in scope, grounded in extensive economic analysis and technology-intensive discovery, and defined by the often-novel application of antitrust to parties and markets in an increasingly interconnected global economy. Her expertise specifically includes analyzing and framing complex legal theories, working closely with testifying economic and industry experts, defeating Daubert attacks, navigating issues involving international parties, and efficiently marshalling terabytes of electronic discovery. With a demonstrated ability to effectively coordinate the prosecution of complex antitrust class actions, the multidistrict litigation court in In re Lithium Ion Batteries Antitrust Litigation (MDL No. 2420) recently appointed Judith as interim liaison counsel for the direct-purchaser plaintiffs.

Recognized by the American Bar Association Antitrust Section, Judith was selected to serve on the International Civil Redress Task Force, and was then appointed Vice Chair of the ABA’s Civil Redress Committee. Judith also serves as Chair of the Antitrust Section of the Bar Association of San Francisco.
