David J. Marshall was a founding partner of Katz, Marshall & Banks (now Katz Banks Kumin) in 2006.  He is now retired as an active partner but continues as Partner Emeritus and Of Counsel, working with the firm on certain whistleblower tips before the Securities and Exchange Commission and the Commodities Futures Trading Commission. 

Mr. Marshall has successfully represented hundreds of whistleblowers and other employees in the financial, pharmaceutical, nuclear, aviation, railroad, healthcare, medical-device, retail and other industries.  He represented some clients in winning awards under the whistleblower-reward programs administered by the SEC, CFTC and DOJ, including one who, in April 2021, was awarded $3.2 million by the SEC for supplying critical information that led to a successful enforcement action against a large financial institution. 

Mr. Marshall achieved success for other clients in cases arising under federal and state laws that protect employees against retaliation from their employers for reporting corporate wrongdoing.  His important victories in whistleblower 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 whistleblower-retaliation complaint against United Airlines resulting in a March 2016 settlement that reinstated all of them to their jobs. 

Over the course of his career, Ms. Marshall established himself as a top whistleblower lawyer, consistently won recognition as a top whistleblower lawyer by Super Lawyers, Washingtonian Magazine and Best Lawyers©.  He is rated by Martindale-Hubbell as “AV Preeminent,” its highest possible peer-review rating. In addition to his legal practice, Mr. Marshall has been very active in professional and social-justice organizations, including the American Bar Association, the Public Justice Foundation, Farmworker Justice, and the Government Accountability Project. He has also provided training to government agencies regarding developments in the nation’s whistleblower laws, has appeared in numerous national and local media as an expert in whistleblower law, and has written extensively on whistleblower issues.

Mr. Marshall earned his law degree from Harvard Law School in 1980.  From 1981 to 1984, he was a staff attorney with the Political Rights Defense Fund, where he represented trade unionists and political activists nationwide in civil liberties, free speech, defamation, and political asylum litigation. He then worked for 12 years as a steelworker, garment worker, freight railroad conductor and refinery worker, and was a rank-and-file union activist in some of the nation’s largest industries and unions, before returning to the full-time practice of law in 1997.

Thirteen Flight Attendants v. United Airlines (2016)
United Airlines and 13 flight attendants that the company relieved of their duties in October 2014 announced on March 8, 2016, that they reached a resolution to their disagreement.  The flight attendants filed a complaint with the U.S. Occupational Safety and Health Administration (OSHA) under AIR 21. As part of the settlement, United will reinstate the flight attendants to their duties and the flight attendants will withdraw their OSHA filing. The remaining terms of the resolution reached between the parties are confidential. Mr. Marshall led the Katz Banks Kumin team responsible for representing the flight attendants.

U.S. ex rel Tracy Lovvorn v. Extendicare Health Services, Inc. (E.D. Pa. 2014)  
In October 2014, whistleblower Tracy Lovvorn and the U.S. Department of Justice announced a $10 million settlement of Ms. Lovvorn’s 2010 qui tam lawsuit against a company whose skilled nursing facilities had provided patients with unnecessary therapy for the sole purpose of obtaining higher reimbursements from Medicare.  Mr. Marshall led Katz Banks Kumin’ team in representing Ms. Lovvorn jointly with Vogel, Slade & Goldstein.  Ms. Lovvorn, who was fired as Extendicare’s Area Director of Rehabilitation for opposing the unlawful practices, received $1.8 million as her relator’s share of the Medicare fraud settlement, plus another $990,000 in settlement of her claims against Extendicare for retaliation and attorneys’ fees.

U.S. ex rel Michael Lindley v. Gallup Organization (D.D.C. 2013)
Mr. Marshall represented whistleblower Michael Lindley in U.S. ex rel. Lindley v. Gallup Organization, a qui tam and retaliation lawsuit that resulted in 2013 in the recovery of $10.5 million in taxpayer funds from a market-research company that called itself “the most trusted name in polling.”  Lindley’s lawsuit alleged that, as Gallup’s Director of Client Services, he found that the company was routinely submitting inflated cost projections to U.S. government agencies in connection with market-research contracts, enabling Gallup to reap huge profits for its work. Lindley’s complaint also claimed that Gallup fired him unlawfully after he reported these practices to senior management. Lindley received $1,929,363 as his share of the government’s settlement with Gallup.  He resolved his claims of retaliation with the company on confidential terms.

Speegle v. Stone & Webster (U.S. Dept. of Labor ARB 2009)
In September 2009, Mr. Marshall led the Katz Banks Kumin legal team that secured an important victory for whistleblowers in the nuclear energy industry. After Katz Banks Kumin client James Speegle lost his job in 2004 for blowing the whistle on nuclear safety lapses at TVA’s Browns Ferry nuclear plant in Alabama, Mr. Marshall represented Mr. Speegle at trial and on appeal to the U.S. Department of Labor’s Administrative Review Board. In a September 2009 decision reinforcing the rights of nuclear workers to speak out about safety issues without fear of retaliation, the Board reversed the trial judge and ruled Mr. Speegle entitled to “the relief that the Energy Reorganization Act affords to a successful litigant.”

Richard Pullman v. Nat’l Air and Space Museum (U.S. Dept. of Labor ALJ 2009)
In 2008 and 2009, Mr. Marshall represented a Smithsonian worker in a whistleblower lawsuit alleging that management at the Air and Space Museum had retaliated against him for speaking out about dangerous levels of asbestos in the museum’s walls. After lighting specialist Richard Pullman filed his whistleblower complaint under the Clean Air Act, the Smithsonian admitted it had known about the asbestos since 1993 but had not told the workers about the problem. Mr. Marshall and Katz Banks Kumin associate Alexis Ronickher litigated Pullman’s case before the Department of Labor and negotiated a successful settlement in July 2009.

Joe Walters v. Deutsche Bank (U.S. Dept. of Labor ALJ 2009)
In March 2009, Mr. Marshall and associate attorney Maura Dundon won a groundbreaking decision that greatly expanded the coverage of the Sarbanes-Oxley Act’s whistleblower provisions.

Capitol Tunnel Workers v. Architect of the Capitol (Cong. Office of Compliance 2007)
In 2006 and 2007, Mr. Marshall represented ten U.S. Capitol tunnel workers in a whistleblower retaliation complaint against the Architect of the Capitol, which is an agency of the U.S. Congress. The workers charged the Architect with harassing and threatening them after they alerted Congress in March 2006 to the life-threatening levels of asbestos and other hazards they faced while working in the utility tunnels that run beneath the U.S. Capitol. In June 2007, the workers and the Architect agreed to a substantial out-of-court settlement that was later approved by the Congressional Office of Compliance.

Consumer Class Actions
In addition to representing whistleblowers, Mr. Marshall has served as class counsel in a number of consumer class-action lawsuits. In 1999-2000 he played a leading role in class actions against the magazine sweepstakes industry, resulting in a $42 million-dollar settlement. In 2001, along with Georgetown University Law Professor Gary Peller, Mr. Marshall served as co-lead counsel in a nationwide class-action lawsuit against the largest “payday” lender in the U.S. The 2003 settlement in this case, in which Mr.Marshall and Mr. Peller partnered with the AARP Foundation Litigation and leading consumer advocates, relieved low-income borrowers of over $50 million of dollars in debt, distributed cash payments to borrowers, and paid cy pres awards to the National Consumer Law Center, the Community Reinvestment Association of North Carolina, and Texas Rural Legal Aid, Inc. — three organizations that play leading roles in the fight against predatory lending.

Testimonials

“David Marshall represented me in securing a very good outcome in a high–profile, hard–fought whistleblower case against a powerful government agency…”

Testimonials Listing

“I am very thankful to David Marshall and Dan Edelman for all of their hard work and efforts in successfully resolving my whistleblower claim against my former employer, a federal credit union. Throughout the entire process, it was very obvious to me that the Katz Banks Kumin team worked together very effectively, and they made a very stressful process for me as positive as possible.

During the mediation session with my former employer, I felt that we were as well prepared as possible and I had high hopes of reaching a fair settlement. I was very pleased with the results, particularly knowing that the credit union had engaged a formidable firm to work in their defense which had been a tough negotiator in the past.

The Katz Banks Kumin team was very professional throughout the process.”

— Former Director of Internal Audit at a federally chartered financial institution

“In 2011 through 2012 I found myself to be in situation that read like a case study from graduate school. I had been recruited and hired by an aerospace firm that served an impressive group of federal customers. Unfortunately, it soon became apparent that my boss was engaging in unethical and illegal behaviour which I subsequently reported to the U.S. government as well as through the corporation’s channels and processes. I found myself a whistleblower and facing retaliation from the corporation. At that time I retained Katz Banks Kumin. The entire team at Katz Banks Kumin were impeccably responsive, knowledgeable and thorough. David Marshall, Dan Edelman, and everyone else at the firm provided flawless counsel, kept me in the loop at all times and we achieved a very favorable outcome. Katz Banks Kumin has my highest possible praise and endorsement for your legal needs and unforeseen challenges.”

— Aerospace executive who reported fraud in government contracts

“I approached Katz Banks Kumin legal when I thought nobody cared about me or the drugs that were going out the door. Katz Banks Kumin legal did care about both the patients we serve and me. They educated me on the process and the respective risks. After engaging Katz Banks Kumin legal, it was like a great burden was lifted; the worry and insecurity of it all went away. David Marshall and Daniel Edelman were outstanding in representing me to a successful outcome. Moreover, I felt that we struck a blow for the unsuspecting patient that needed pharmaceuticals for better quality in health. You have choices in who represents you but as for me, Katz Banks Kumin was the best and only choice for strong sound legal representation.”

— Senior compliance officer in the pharmaceutical industry who complained of adulterated drugs

“The fraud in skilled nursing facilities is abhorrent … and I finally got fired for complaining to management about it. Thanks to good luck and the Internet I found David Marshall and Alexis Ronickher at Katz Banks Kumin. They understood the issues and helped me get a settlement. Katz Banks Kumin levels the playing field. I’m very grateful!”

— Occupational Therapist who reported fraudulent billing to Medicare in a skilled nursing facility

“David Marshall and Abigail Cook-Mack are two of the finest professionals I have ever met. They showed compassion, resolve and a tenacity that is simply world class. My case was extremely complicated and spanned many years and involved the most senior management in my institution. Taking on the most powerful people on Wall Street in the name of justice and doing the right thing involved enormous risk, but Katz Banks Kumin put all of their considerable resources behind me, and in the end I was rewarded with a seven figure settlement from my former firm. My family and I are truly grateful to David, Abby and the Katz Banks Kumin team for helping us right a wrong and allowing me and my family to move on with our lives satisfied with an exceptional outcome. Their track record is second to none. A call from Katz Banks Kumin to your former or current employer sends instant chills up their spines.

I was very comfortable making decisions based on the education that David provided. David was informative, understanding and most importantly, supportive of me – I didn’t feel alone. I am so thankful that I had David Marshall and the Katz Banks Kumin team representing me for a fantastic outcome!”

— Chief Compliance Officer in the pharmaceutical industry who blew the whistle on fraudulent practices

If you are looking for a law firm in regard to a whistle blower case action suit I would highly recommend using Katz Banks Kumin. David Marshall, Matt Stiff, and the staff are unsurpassed in the work that they have done for me in regard to my case. To them you are not just a case number; you are individual person with a problem that should be rectified. In my opinion they have went above and beyond to help my family. They are a great law firm that has exceeded all of my expectations and I would highly recommend them to anyone.”

He not only went toe to toe with the agency’s lawyers at every step, but he also had the strategic ability, sense of timing and political know-how that it took to deal with a well-financed opponent that thought it could outsmart us and defeat us. And from our first conversation to the end, I always knew that David was 150% on my side.”

— Richard Pullman, an Exhibit Specialist for 27 years at the Smithsonian Air & Space who suffered retaliation after blowing the whistle on the presence of asbestos at the museum

“For five months, I tried (unsuccessfully) to resolve a whistleblower situation at my Midwest nuclear power plant. Katz Banks Kumin resolved this issue in less than six weeks.

My wife and I will be forever grateful for your professionalism and your execution of this case.”
