Federal Court Blocks ICE's Warrantless Arrests in Oregon Over ELITE Tool Abuse
A federal court in Oregon has ruled against US Immigration and Customs Enforcement (ICE) over its use of warrantless arrests. The decision follows concerns about the agency's reliance on an advanced analytics tool called ELITE, which critics claim unfairly targets vulnerable communities. Judge Karin J. Immergut found that ICE's practices in the state violated constitutional rights.
The case centred on Operation Black Rose, a 2025 enforcement campaign in Portland that led to over 1,200 arrests by mid-December. Evidence revealed that officers were pressured to meet daily arrest quotas, raising questions about the legality of their methods.
Operation Black Rose began in autumn 2025 as part of ICE's broader enforcement efforts. Officers in Portland were instructed to make at least eight arrests per team each day. Internal documents later showed that these targets took precedence over legal justifications for detentions.
To identify locations for arrests, ICE agents used ELITE, a data analytics platform developed by Palantir under a £23.5 million ($29.9 million) contract. The tool compiles dossiers on individuals by pulling data from government and commercial sources, including Medicaid records. Critics, such as the Innovation Law Lab, argue that ELITE disproportionately affects marginalised groups rather than focusing on serious criminal offenders. In her ruling, Judge Immergut sided with plaintiffs who challenged ICE's warrantless arrests in Oregon. She determined that the agency's actions breached the Fourth and Fifth Amendments, which protect against unreasonable searches and ensure due process. As a result, ICE must now obtain supervisory administrative warrants before detaining individuals for civil immigration violations in the state. Oregon remains the only US state with such a court-ordered requirement as of March 2026. The decision highlights ongoing tensions between federal enforcement strategies and constitutional protections, particularly when advanced technology is involved.
The ruling forces ICE to change its procedures in Oregon, requiring warrants for immigration arrests. It also casts a spotlight on the use of tools like ELITE, which rely on vast datasets to guide enforcement. Legal observers note that the case could influence future challenges to ICE's methods in other states.
