In a big change for defense contractors, Congress has amended 10 U.S.C. § 3372 to make clear that a Department of Defense (DoD) contracting officer’s unilateral definitization of an undefinitized contract action is directly appealable to the Armed Services Board of Contract Appeals (ASBCA) or the Court of Federal Claims. Congress’s change (made under Section 803 of the Servicemember Quality of Life Improvement and National Defense Authorization Act (NDAA) for Fiscal Year (FY) 2025) (we report on the FY 2025 NDAA here) is contrary to recent ASBCA and Federal Circuit decisions.
