Federal Circuit Affirms Palantir's DCGS-A Win: FASA Commercial-Item Preference Is Judicially Enforceable

The U.S. Court of Appeals for the Federal Circuit affirmed the Court of Federal Claims’ ruling in Palantir USG, Inc. v. United States (No. 17-1465), permanently enjoining the Army from proceeding with its Distributed Common Ground System — Army Increment 2 (DCGS-A2) procurement until it complied with the Federal Acquisition Streamlining Act’s commercial-item preference mandate.

The Army had issued a single-source IDIQ development solicitation in 2015 seeking a system architect, developer, and integrator for DCGS-A2 — the Army’s primary battlefield intelligence system — structured as a custom-development contract that excluded commercial vendors including Palantir. Palantir filed a pre-award bid protest in the Court of Federal Claims (Case No. 1:16-cv-00784) arguing the Army violated FASA 10 U.S.C. § 2377(c) by failing to determine whether commercial items could meet its requirements before issuing the solicitation, despite being explicitly informed of Palantir’s Gotham platform.

COFC Judge Marian Blank Horn ruled for Palantir in October–November 2016, finding the Army had been aware of a potential commercial solution and had issued the non-commercial contract anyway. The Federal Circuit affirmed: the Army acted “arbitrarily and capriciously”; the agency’s rejection of the commercial alternative offered only “conclusory assessment” without documented reasoning; FASA’s commercial-preference mandate is justiciable and judicially enforceable, not a discretionary policy aspiration.

The follow-on outcome established the capture-via-protest playbook’s completion: the Army reopened competition under the FASA-compliant framework. In March 2019, the Army awarded the DCGS-A Capability Drop 1 contract to Palantir and Raytheon at $876 million total value over ten years. Palantir — which had successfully sued the Army — then beat Raytheon in a 12-month pilot program to win the first $20 million task order.

The 2018 Federal Circuit ruling became the legal precedent enabling Palantir’s 2025–2026 DIA MARS protest sequence. The mechanism is identical: agency builds in-house while knowing of commercial alternatives; Palantir invokes FASA § 2377 commercial-item preference; files protest to force competition it is structurally positioned to win. The ruling gave procurement lawyers across the defense contracting bar notice that commercial-item market research documentation is now subject to judicial scrutiny, converting a previously aspirational statutory preference into a litigation tool.
