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.

The US Soccer Federation appointed a team including New York's Lawrence Buterman and Washington DC's Gregory Garre to defend it in a claim brought by the NASL alleging that US Soccer and other professional leagues conspired to exclude NASL from the top divisions to monopolize the market. Also notable in Washington DC are Jennifer Giordano and Margaret Zwisler, while Al Pfeiffer sits in the San Francisco office. They recently acted for high-profile clients in the healthcare, telecoms and media sectors, such as Highmark and Cox Communications. Amanda Reeves co-heads the department in Washington, D.C., and was part of the team which defended Genentech in a suit filed by Russian biotechnology company Biocad alleging the client and other drug manufacturers engaged in predatory pricing and unlawful tying arrangements to prevent Biocad from competing in the US market. Named individuals are based in San Francisco unless otherwise stated.
