Dominique L. Casimir



Dominique Casimir concentrates her practice on addressing the many issues confronting government contractors today, including complex disputes, internal and government investigations, enforcement, and strategic counseling. Dominique’s litigation experience includes achieving wins for her clients in bid protests at the U.S. Court of Federal Claims, the Government Accountability Office, and the Federal Aviation Administration Office of Dispute Resolution for Acquisition, as well as in claims litigation before the Boards of Contract Appeal. She has a track record of success in consequential government contracts litigation involving such issues as the statute of limitations, contractor key personnel issues, and the AbilityOne program. Dominique has also achieved wins for her clients in the arbitration of prime-sub disputes, and she has helped contracting parties resolve their disputes without recourse to litigation.

Chambers USA notes that sources say that Dominique “is excellent and a practical business-oriented attorney” and “an experienced litigator and well-rounded attorney.” And Legal 500 United States shares that a source says that Dominique “is a hard nosed litigator, who will not shy away from a battle when one is needed.” Another source comments, “Dominique was very responsive and available, even with the difference in time zones. She pushed back on the government lawyers, in a nice but insistent way, as they were being unreasonable.”

In 2023, Legal 500 United States sources shared additional observations about working with Dominque, noting that Dominique “showed up to fight for me every day, at any time, and made sure I knew that I was not alone. Dominique Casimir made sure that I was well informed, and also helped to provide a voice of reason within my disputes that made all of the noise go away.”

As a former co-chair and current vice-chair of the ABA Public Contract Law Section’s Committee on Debarment and Suspension, Dominique applies her deep experience and skilled judgment to assist contractors facing potential exclusion from government programs, including in complex parallel proceedings involving the Department of Justice. She also advises clients on whether and how to make mandatory or voluntary disclosures to government entities, and on how to maintain good standing with the government. Dominique maintains a robust and active investigations practice in which she is regularly called upon to handle ethics- and hotline-related investigations, investigations of employee misconduct, investigations of alleged procurement fraud, and violations of the False Claims Act, as well as complex and document-intensive internal investigations undertaken in response to Civil Investigative Demands and other investigations arising in crisis contexts. Dominique also maintains an active regulatory counseling practice, in which she ensures that her clients maintain compliance with a broad array of FAR and DFARS requirements, including Department of Defense cybersecurity requirements.

With nearly 20 years of experience, Dominique has represented some of the world’s largest multinational corporations, small businesses, and everything in between. She has appeared before numerous federal agencies, and her primary objective is to help government contractors address legal risk so that they can focus on achieving their business objectives.
