Caleb E. McCallum

McCallum Caleb

Caleb McCallum assists government contractors in all aspects related to procurement and litigation. Caleb has worked on bid protests before the Government Accounting Office (GAO) and U.S. Court of Federal Claims, and on other administrative proceedings before federal agencies. He also guides clients through commercial litigation between private parties involving a wide range of matters before both state and federal courts, with a focus on disputes between government contractors.

Caleb's experience with government contracts covers a broad range of subject areas. Caleb has deep experience assisting clients litigating bid protests at the state and federal levels. This includes sustained decisions before the GAO, successful interventions defending awards at both GAO and the Court of Federal Claims, and a successful outcome using alternative dispute resolution procedures before the Federal Aviation Administration's (FAA) Office of Dispute Resolution for Acquisition (ODRA).

Along with bid protests, Caleb has significant compliance and investigatory experience. He was seconded to a major international nonprofit aid organization in 2021-2022, assisting with internal investigations and compliance matters. He has participated in and drafted reports of internal investigations of nonprofits and local government entities, as has advised clients regarding the use of grant funds pursuant to the Uniform Guidance and related regulations.

Another major area of experience is in the application of the Small Business Administration's (SBA) regulations. In the early days of the coronavirus pandemic, Caleb was a member of Venable's CARES Act task force, advising clients on the Paycheck Protection Program and its complex affiliation rules. Additional government contracts experience includes drafting claims, requests for equitable adjustments, and termination settlement proposals, and researching and advising clients on the application of federal regulations.

Caleb also spends significant time engaged in commercial litigation. While much of his practice focuses on litigation between or related to government contractors—namely prime-sub disputes and employee mobility issues relating to enforcement of restrictive covenants—he has been involved in litigation on a wide variety of topics at both the trial and appellate court levels. This includes arbitration and enforcement of an arbitration award in federal court, zoning appeals, construction disputes, derivative suits, and trust and estate litigation.

During law school, Caleb was a summer associate at two different law firms, where he gained experience in many areas of litigation, including contract claims between sub and prime contractors, land disputes, and civil rights. He also served as a judicial intern for the Honorable Joel C. Hoppe, Magistrate Judge, of the U.S. District Court for the Western District of Virginia.
