An immigrant rights and advocacy group has filed a lawsuit against Immigration and Customs Enforcement (ICE) seeking records related to the agency’s use of Palantir tools. 404 Media first revealed a tool called ELITE and its links to Palantir in January, based in part on a leaked user guide for ELITE. ICE uses ELITE to find which neighborhoods to raid, according to testimony from an ICE official.“The requested records include information of great national significance, and will detail the ways Defendants have made use of Palantir’s technology products to centralize, analyze, and visualize data around individuals residing in the United States and their social relationships to identify target individuals and communities in highly publicized immigration raids,” Just Futures Law wrote in its complaint filed on Thursday. 💡Do you know work at Palantir or ICE? I would love to hear from you. Using a non-work device, you can message me securely on Signal at joseph.404 or send me an email at joseph@404media.co.The lawsuit follows a Just Futures Law Freedom of Information Act (FOIA) request seeking related documents. The lawsuit also targets the Department of Homeland Security (DHS).Just Futures Law is seeking, among other things, unredacted copies of communications between ICE and Palantir discussing various tools and systems, including ImmigrationOS; communications between ICE and members of DOGE discussing the systems (DOGE was working on a “master database” to track immigrants, WIRED reported); memorandums of agreement and similar between ICE, DOGE, and other agencies; copies of the specific Palantir contracts; training material about ImmigrationOS; and presentations created by ICE discussing the systems.As 404 Media reported, ELITE, or Enhanced Leads Identification & Targeting for Enforcement, populates a map with potential deportation targets, and provides ICE users with a dossier on each person. It also provides a “confidence score” on that person’s current address. Other criteria available on the map include “Bios & IDs,” “Location,” “Operations,” and “Criminality.”
