Representative Experience

  • Successfully defended a contractor from being debarred for alleged negligent supervision of a subordinate who mischarged hours of personal time to the government. 
  • Successfully negotiated and settled construction claims, including delays, change in concrete inspection procedures, and government breaches of the duties to cooperate and not to hinder and the duty of good faith and fair dealing.
  • Successfully represented a government contractor who the government had unjustifiably terminated for default from a commercial item supply contract for the delivery of fuel to Bagram Air Base in Afghanistan. On appeal, the Armed Services Board of Contract Appeals found the government had not met its burden to demonstrate a prima facie case of the contractor’s default. The termination was converted from a termination for default to a termination for convenience.
  • Successfully represented a government contractor on appeal before the Armed Services Board of Contract Appeals. On appeal, Ms. Brier claimed that the contractor was entitled to compensation for delivery fees and invoices left outstanding on its delivered orders. After a summary proceeding before the Armed Services Board of Contract Appeals, the Administrative Judge issued a binding decision sustaining the contractor’s appeal of all four orders and granting the contractor full payment on its invoices, plus interest.
  • Successfully represented a client in a request for remission or mitigation of funds seized as a result of an asset forfeiture matter from 2010. Ms. Brier was able to demonstrate to the U.S. Postal Inspector Service that the funds seized seven years earlier were, in fact, traceable to a legitimate source and were remitted back to the client.
  • Successfully represented an unsuccessful offeror in a bid protest of a subcontract award before the Government Accountability Office (GAO). Within days of filing the protest, the government issued a notice of corrective action, which inter alia, identified irregularities in the award, acknowledged that errors were made in the assignment, and ultimately resulted in the termination of the subcontract award.
  • Successfully represented a contractor on the appeal of a base debarment from certain Department of Defense installations overseas. After review of the surrounding facts and circumstances examined in Ms. Brier’s written appeal, the Department of the Army approved the appeal and reinstated the contractor’s access to all previously barred installations. The contractor has since returned to working overseas on behalf of the United States military.
