A transparency advocacy organization has filed a comprehensive legal challenge against multiple federal agencies, alleging they have systematically violated public records laws by refusing to release documents detailing their use of data analysis systems developed by technology contractor Palantir.
The 11-page complaint, filed Tuesday by American Oversight, targets several major government entities including the Department of Homeland Security, Immigration and Customs Enforcement, Centers for Disease Control and Prevention, Internal Revenue Service, and the Social Security Administration. The organization contends these agencies have repeatedly failed to comply with Freedom of Information Act requirements regarding their data-sharing practices and agreements with the technology firm.
The legal action follows what the watchdog group characterizes as an expansion in data-sharing activities across federal agencies, particularly after a March 2025 executive order that directed agency heads to remove barriers preventing information sharing between government departments. According to the lawsuit, this directive has substantially increased government engagement with data analysis contractors.
American Oversight Executive Director Chioma Chukwu emphasized the importance of transparency regarding government data practices. She noted that centralized data systems allowing the compilation and analysis of extensive information without public oversight represents a significant concern for citizen privacy.
The lawsuit details extensive document requests submitted to various agencies throughout the previous summer. These requests sought comprehensive records including email communications between agency officials and company representatives, complete copies of contracts and agreements, documents governing access to personally identifiable information, and formal directives related to data-sharing protocols.
Despite these requests, the plaintiffs report receiving minimal response from the targeted agencies. The IRS provided the most substantial reply, delivering an interim response containing 619 pages of records with indicated redactions. However, the agency has not delivered a final response or completed processing of the full request. Other named agencies have provided only basic acknowledgments of receiving the requests, with no meaningful follow-up or document production.
The lawsuit specifically requests all email communications between designated agency officials and company representatives, complete copies of written agreements between agencies and the contractor, records governing access to sensitive data, and all directives or policies related to data-sharing arrangements. Additionally, the plaintiffs seek any informational materials, summary documents, or notes related to these systems.
The legal challenge presents two primary claims against the agencies. First, the plaintiff alleges the agencies failed to conduct proper searches for responsive records as required under FOIA. Second, they claim the agencies have wrongfully withheld non-exempt documents that should be publicly available.
Through this litigation, American Oversight seeks court orders compelling the agencies to conduct comprehensive searches for all responsive records and to produce these documents within a court-specified timeframe. They also request an injunction preventing the government from continuing to withhold such records and seek reimbursement for legal costs.
The complaint notes that the technology firm in question was co-founded by Peter Thiel and is currently led by Alex Karp, who made a million-dollar contribution to a political action committee. Since early in the current administration, the company has obtained federal contracts worth hundreds of millions of dollars for various services including artificial intelligence capabilities and data analysis across multiple federal departments.
The lawsuit reflects growing concerns among privacy advocates and legislators about the potential development of extensive surveillance capabilities and possible misuse of tools that process Americans’ sensitive personal information. The plaintiffs argue that conducting such operations without transparency prevents the public from understanding how these systems function or against whom they might be deployed.
