Katz Banks Kumin Announces Retirement of Founding Partner David Marshall

With its recent name change, leading national employment, whistleblower, and civil-rights law firm Katz Banks Kumin (formerly Katz, Marshall & Banks) announces the retirement of Founding Partner David J. Marshall.  Although retired as a Partner, Mr. Marshall will continue with the firm in an Of Counsel capacity, working on select whistleblower tips before the Securities and Exchange Commission and the Commodities Futures Trading Commission. 

Mr. Marshall, a 1980 graduate of Harvard Law School, joined predecessor firm Katz, Marshall & Banks as a Founding Partner at the firm’s inception in 2006, and played a leading role at the firm until he began transitioning to retirement in early 2020.  During these years, Mr. Marshall established himself as a top whistleblower lawyer both locally and nationally, consistently winning recognition by Super Lawyers, Washingtonian Magazine and Best Lawyers.  

Mr. Marshall has successfully represented hundreds of whistleblowers in the financial, pharmaceutical, nuclear, aviation, railroad, healthcare, medical-device, retail, and other industries.  When Congress created the SEC and CFTC whistleblower-reward programs in 2010, Mr. Marshall quickly established himself as a preeminent expert nationally in the workings of the programs, and led the firm in its work in this area for nearly a decade. During these years, the SEC Whistleblower Practice Guide that Mr. Marshall authored annually became the most comprehensive and definitive guide to the program for whistleblowers and their lawyers, and he worked with the SEC to strengthen the program in several areas, notably its prohibition of corporate efforts to impede employees from providing information to the SEC. Mr. Marshall has successfully represented numerous whistleblowers in the SEC, CFTC and IRS reward programs, as well as in “qui tam” lawsuits that help the Department of Justice and taxpayers recover the proceeds of fraud against the United States. 

In addition to his representation of whistleblowers in these programs, Mr. Marshall achieved many victories for clients over the course of his career under federal and state laws that protect employees against retaliation for reporting corporate and government wrongdoing.  These cases involved entities such as the Architect of the Capitol (asbestos), Deutsche Bank (financial reporting), the Brown’s Ferry Nuclear Plant (nuclear safety), Lockheed Martin (defense procurement), and the Smithsonian National Air and Space Museum (asbestos).  In 2015-2016, Mr. Marshall represented thirteen flight attendants in a highly publicized whistleblower-retaliation case against United Airlines under federal aviation-safety laws, resulting in a March 2016 resolution that reinstated all of them to their jobs. 

In addition to his legal practice, Mr. Marshall has been very active in professional and social-justice organizations, serving as: whistleblower-side co-chair of the American Bar Association Labor and Employment Section’s Subcommittee on the Sarbanes-Oxley Act; a member of the Board of Directors of the Public Justice Foundation; a member of the steering committee of the Shelley Davis Memorial Fund of Farmworker Justice; and an advisory committee member for the Government Accountability Project.  

The firm will miss Mr. Marshall greatly. He has been a great colleague, a mentor to many, and played an invaluable role in building the firm into the highly successful one that it is today. We look forward to having him continue on in an Of Counsel capacity, where he can continue to share his extensive expertise and knowledge with the firm, as he enjoys a well-deserved retirement.
