FOIA Document: Review of the Use of Special Management Units for ICE Detainees

New documents obtained by the ACLU reveal critical details about an Immigration and Customs Enforcement (ICE) policy directive issued under the Biden administration regarding the use of special management units, or solitary confinement cells, in immigration detention. The documents were obtained as a result of a FOIA lawsuit filed by the ACLU in January 2025. The new findings are critical to understanding what policies immigrants in ICE detention may be subject to, and in turn, will enable legal counsel to better defend immigrants who are subject to solitary confinement in ICE detention.
