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

Washington DC-based Amanda Reeves and San Francisco’s Christopher Yates are global co-chairs of the practice at Latham & Watkins LLP. The team recently increased its headcount in the US through the hires of counsel Peter Todaro and Farrell Malone, who joined in Washington DC from King & Spalding LLP and Arnold & Porter LLP respectively, and Michael Lacovara, who joined in New York from Freshfields Bruckhaus Deringer LLP. In addition to representing clients in cartel-related litigation arising from government investigations, the firm also handles non-cartel business-to-business litigation (which covers a wide range of conduct issues), as well as contentious merger clearances. San Francisco-based Daniel Wall and Sarah Ray and others successfully defended Oracle against a putative class action initiated by plaintiffs alleging a conspiracy between the client and other technology companies not to hire or solicit each other’s employees. Margaret Zwisler, Jennifer Giordano and Allyson Maltas (all based in Washington DC) secured an appellate-level win for Time Warner Cable in the Set-top Cable Television Box Antitrust Litigation. Al Pfeiffer in San Francisco is highly recommended.
