Prominent attorneys Karen Dunn, Jeannie Rhee and William Savitt are among the legal team representing Amazon.com Inc. in a Federal Trade Commission suit alleging the corporate giant has overcharged advertisers.

Court documents filed in federal court Monday show the trio, along with a string of other attorneys, as representing Amazon. Savitt, who has gained attention for taking on Elon Musk in court, recently left Wachtell Lipton for rival Gibson Dunn, while Dunn and Rhee are prominent ex-Paul Weiss attorneys and among those who last year started the boutique firm Dunn Isaacson Rhee.

Court documents also show Gibson Dunn partners Natalie Hausknecht and Gustav Eyler are representing Amazon, along with John Goldmark, a partner at Davis Wright Tremaine. Gibson Dunn has done both corporate and litigation work for Amazon for years.

The lawsuit, filed Monday in the US District Court for the Western District of Washington, alleges that Amazon has systematically overcharged about 1.2 million advertising customers since 2019 by “manipulating the ‘auctions’ that it uses to set the price of ads on its platform.” It said Amazon’s actions “likely illegally” have taken more than $20 billion from its advertising customers.

More than 20 states including New York and California joined the FTC in bringing the lawsuit against the company.

“Amazon represents, and advertisers believe, that competitive auctions set the prices for advertising on its leading e-commerce website. But, in reality, Amazon overrides and replaces the actual auction results with higher prices set by Amazon to increase its profits,” according to the lawsuit. The suit also said that the e-commerce giant had secretly inflated the auction prices for “Sponsored Products, Sponsored Brands and Sponsored Display,” which are three of the company’s advertising products.

Amazon, in a response posted online, called the FTC action a “misguided lawsuit” and said the agency’s complaint cited no evidence of price increases for consumers.

The case is FTC v. Amazon, W.D. Wash., 2:26-cv-03097, 8/31/26
