David P. Dean has successfully represented labor unions and employees for over twenty years in multiple forums. For example, he is co-lead counsel in antitrust class actions instigated and supported by the Service Employees International Union (“SEIU”) on behalf of Registered Nurses against hospitals in several cities for colluding on wages. These suits have won over $100 million in settlements so far, along with agreed injunctions on exchanges of wage information in Albany and Detroit. Mr. Dean is also now advising and litigating in support of accountability and organizing efforts by fast food workers, both in federal court and before the National Labor Relations Board. In 2014, the Department of Justice entered a $98 million settlement with a large for-profit hospital chain in a Qui Tam suit Mr. Dean worked with the SEIU to develop and litigate as a relator. Among many victories for unions and individual workers, he previously succeeded on behalf of the United Farm Workers and Farm Labor Organizing Committee enjoining the Department of Labor to raise minimum wage rates annually for over 50,000 migrant farm laborers.

Mr. Dean also litigates on behalf of nonprofit organizations. For example, he successfully enjoined the United States Air Force on behalf of the National Security Archive Fund to create a functioning FOIA system, including instituting agency-wide centralized computer tracking of requests; retaining additional and higher level FOIA personnel; instituting regular required trainings; and reforming the Air Force’s electronic reading rooms. As a further result of the suit, the Air Force was forced to produce critical documents on the history of U.S. nuclear policy and the Archive received one of the largest fee awards ever procured in a FOIA suit.

Mr. Dean has been awarded an AV Preeminent rating by Martindale Hubbell, the highest rating achievable by attorneys, and was voted by his peers as one of the Best Lawyers in America, and chosen as a District of Columbia Super Lawyer in 2013 - 2015.
