Federal Circuit Clarifies When Affirmative Defenses Must Be Submitted as Claims, and When Interest Runs

Client Alert | 2 min read | 07.17.19

On July 9, 2019, the Federal Circuit issued a decision in Army v. KBR, which although nonprecedential, further clarifies when an affirmative defense constitutes a CDA claim that – for jurisdictional purposes – requires a prior Contracting Officer’s Final Decision.

As background, the Army withheld $44M in allegedly unallowable security costs from KBR’s invoices. KBR submitted consolidated claims arguing that the costs were allowable, and – later – a “protective” claim that the Army had separately breached the contract. In 2015, the Federal Circuit ruled that the costs were “unallowable,” but remanded for a determination of whether KBR’s breach allegation was properly asserted and, if so, could entitle KBR to the unallowable costs. On remand, KBR asserted that the Army’s prior material breach of the contract entitled KBR to the unallowable $44M. KBR prevailed, and the Federal Circuit affirmed. 

The Court agreed that the Army’s withholding of $44M was a Government claim (even though KBR had submitted claims challenging the government’s withholding), and that KBR’s later assertion of prior material breach was an affirmative defense to the Government’s $44M claim for unallowable costs. The Federal Circuit clarified that an affirmative defense of prior material breach, as written, may be asserted without a prior CO’s Final Decision. In contrast, an affirmative defense that asks/requires (expressly or implicitly) the Court to consider an equitable adjustment to the contract terms – no matter how deserving – must first be submitted to the CO for a final decision. The Court explained “we have treated affirmative defenses asserted under the contract[] differently,” and announced as a matter of first impression that “[w]hether prior material breach is asserted to eliminate debt as in Laguna, or to recover withheld payments as here, the effect is the same — the defense is asserted to defeat a wrongful monetary claim.” Lastly, because KBR’s claims were legally recharacterized as Government claims, and KBR merely prevailed on an affirmative defense to avoid recapture of prior payments, the Court considered whether KBR was entitled to interest under the CDA. The Court held that KBR was entitled to interest on the $44M running from the date that it submitted its various claims to the CO because “that is all that is required for the [CDA] interest clock to begin,” and the Court was “aware of no authority instructing that a contractor must state in a claim the legal theory upon which it ultimately recovers to start the running of interest.”

Twin Executive Orders Seek to Spur Quantum Leap in Technology and Cybersecurity

On June 22, 2026, President Trump signed two executive orders, “Securing the Nation Against Advanced Cryptographic Attacks” (Quantum Security EO) and “Ushering in the Next Frontier of Quantum Innovation” (Quantum Innovation EO), marking the most significant federal action on quantum technology since the Quantum Computing Cybersecurity Preparedness Act of 2022, which directed agencies to harden their information systems against quantum-enabled hacking. The orders seek to speed the development of quantum computers, which are advanced processors that can calculate multiple possibilities simultaneously and thus solve problems exponentially faster than traditional computers. At the same time, the orders look to protect against the danger that quantum technology can “break” traditional encryption by easily decoding it. Of particular note for government contractors, the Quantum Security EO directs agencies to update federal acquisition regulations to require contractors by 2031 to adopt information processing standards that resist quantum-enabled codebreaking....
