Work Department

Peggy Zwisler is a partner in the Litigation & Trial Department of Latham & Watkins' Washington, D.C. office. She is a past Global Co-chair of Latham's nationally recognized Global Antitrust & Competition Practice.  

Ms. Zwisler is an antitrust trial lawyer with more than 40 years of experience. She has successfully represented antitrust defendants in numerous trials and achieved significant victories for them through both procedural and substantive dispositive motions. Most recently, she won a directed verdict for Cox Communications after trial in a class action alleging that Cox tied the sale of its cable services to the lease of set top boxes. She also recently won a judgment in favor of her client, The London Metal Exchange, on the ground that it is entitled to sovereign immunity because it is an instrumentality of the government of the United Kingdom, for which she was named Litigator of the Year for 2015 by Global Competition Review.

Margaret Zwisler - Latham & Watkins LLP

Within: Civil litigation/class actions: defense

Latham & Watkins LLP delivers excellent results in high-stakes litigation. As an example, Amanda Reeves (who chairs the US antitrust practice alongside Christopher Yates in San Francisco), Lawrence Buterman in New York and Daniel Wall, also in San Francisco, successfully defended Genentech against a lawsuit brought by Russian drug manufacturer Biocad JSC over an alleged scheme to delay Biocad from entering into the US market generic versions of three cancer drugs. In the auto parts space, Marguerite Sullivan and others represented Sumitomo in MDL class action cases related to wire harnesses and heater control panels. Elsewhere, the firm is defending the US Soccer Federation (USSF) against a lawsuit filed by the North American Soccer League (NASL) over the USSF’s allegedly anti-competitive division structure. In recent developments, Alan Devlin re-joined the firm from the FTC, while Joseph Serino and Eric Leon in New York were hired from Kirkland & Ellis LLP. San Francisco-based Kirsten Ferguson made partner. Margaret Zwisler is also noted. Named individuals are based in Washington DC unless otherwise stated.
