Decision: Zadvydas v. Davis, 533 U.S. 678 (2001).

Zadvydas supplies the framework for habeas challenges when a final removal order exists but no country is likely to accept the detainee.

Removal could not be carried out

Two resident aliens remained detained after final removal orders. Germany and Lithuania declined to accept Zadvydas, and Cambodia had no repatriation agreement covering Ma. The Court examined both the actual removal prospects and the standards the lower courts had applied. Zadvydas, 533 U.S. at 684–686, 702.

The Court avoided a serious constitutional problem

Indefinite civil detention would raise grave due-process concerns. The Court therefore read the statute to contain an implicit temporal limit tied to its removal purpose.

Six months creates a burden-shifting framework

After six months, a detainee who provides good reason to believe removal is not significantly likely in the reasonably foreseeable future is entitled to a government response with evidence rebutting that showing.

Disposition

The Court vacated and remanded both cases for application of the reasonable-foreseeability standard. Release may include supervision and detention may resume if circumstances materially change.

Key takeaways

• Calculate the statutory removal period from the complete order, court-review and custody history; do not assume every ICE arrest starts the six-month inquiry.
• Document travel-document requests and country responses.
• Develop evidence of future removability, not only elapsed time.
• Address supervision and changed circumstances.
