How to Challenge an Unlawful ICE Detainer

An ICE detainer can be challenged as unlawful if it lacks probable cause or violates the Gonzalez v. ICE class action settlement. Class members held on detainers without a judicial warrant or valid immigration basis may seek release or damages. Contact an immigration attorney immediately and request your detainer documents from the facility where you are held.

Quick Answer

Yes, you can challenge an ICE detainer if it was issued without proper legal authority. The Gonzalez v. ICE class action settlement established enforceable rights for certain immigrants held on detainers that lacked probable cause. An immigration court or federal court may order your release if the detainer is found unlawful.

Who Is Covered: Conditions and Eligibility

The Gonzalez v. ICE settlement covers individuals who were — or are — detained based on an ICE detainer (also called a Form I-247) that was issued without a judicial warrant and without sufficient probable cause to believe the person was removable. Key eligibility factors include:

• You were held beyond your criminal sentence solely because of an ICE detainer, not an independent immigration arrest.
• The detainer lacked a judicial warrant — ICE detainers are administrative requests, not court orders, and local jails are not legally required to honor them.
• You did not have a prior order of removal (deportation order) at the time the detainer was lodged, or the detainer was based on mistaken identity or an error in your immigration record.
• You are or were held in a jurisdiction covered by the settlement — check with an attorney to confirm your jurisdiction's status.

Immigration attorney Ilya Fishkin, immigration attorney advises detained immigrants to obtain a copy of their detainer form immediately to verify the legal basis stated by ICE.

Step-by-Step: How to Challenge Your ICE Detainer

1. Request your detainer documents. Ask the jail or detention facility staff for a copy of your ICE detainer (Form I-247A or I-247D). You are entitled to know the stated legal basis for your hold.
2. Determine whether a judicial warrant exists. An ICE detainer is NOT a judicial warrant. If no judge-signed warrant accompanies the detainer, this is a key ground for challenge.
3. Contact an immigration attorney immediately. Time is critical. An attorney can file a habeas corpus petition in federal district court under 28 U.S.C. § 2241 to challenge your unlawful detention.
4. Assess your class membership under Gonzalez v. ICE. Your attorney will evaluate whether you fall within the class definition established by the settlement and what remedies apply to your situation.
5. File a habeas corpus petition or motion for bond. In federal court, a habeas petition challenges the legality of your detention. Separately, in immigration court, your attorney can file a motion for a bond hearing before an immigration judge.
6. Request a bond hearing before an immigration judge. Under INA § 236, you have the right to a bond hearing. The immigration judge must determine whether you are a flight risk or danger to the community before continued detention is justified.

What the Law Says

ICE detainers are governed by 8 C.F.R. § 287.7, which frames them as requests — not mandates — for local law enforcement to hold an individual for up to 48 hours beyond their scheduled release. Courts in multiple federal circuits have ruled that detainers without judicial warrants violate the Fourth Amendment's probable cause requirement.

The Gonzalez v. ICE class action (C.D. Cal.) resulted in a settlement that requires ICE to follow stricter standards when issuing detainers, including documenting the basis for probable cause. Violations of the settlement can be enforced through the federal court that approved it.

Under INA § 236(a), ICE must establish legal authority for detention. An order of removal (deportation order) against you does not automatically justify a new detainer if that order is being challenged or has been stayed. If ICE issues a detainer based on mistaken identity, you may also have claims under the Privacy Act (5 U.S.C. § 552a).

Key Rights to Assert

• Right to a bond hearing under INA § 236 — do not waive this right without legal counsel.
• Right to counsel — you may hire a private immigration attorney; free legal help is available through nonprofit organizations.
• Right to contest deportation proceedings — a detainer does not mean deportation is inevitable; you may have defenses including asylum, cancellation of removal, or adjustment of status.
• Right to appeal — if an immigration judge issues an order of removal (deportation order), you have 30 days to appeal to the Board of Immigration Appeals (BIA). A motion to reopen must generally be filed within 90 days.
