Summary
The Supreme Court held that the statute authorizing post-removal detention must be read to contain a ‘‘reasonable time’’ limitation (presumptively six months) and does not permit indefinite detention of removable aliens when removal is not reasonably foreseeable.
Background & Context
Kestutis Zadvydas was born in a German displaced persons camp in 1948 to Lithuanian parents. He was never a German citizen. He immigrated to the United States as a child and became a lawful permanent resident, but he never became a U.S. citizen. After multiple criminal convictions as an adult, immigration authorities ordered him deported. The problem: neither Lithuania nor Germany would accept him. Lithuania didn't recognize him as a citizen; Germany had no claim on him either. Zadvydas was trapped — ordered out of the country he'd lived in for decades, with nowhere to go. Immigration law gives the government 90 days after a final deportation order to actually remove someone. After that period, the law allows continued detention. The INS kept Zadvydas in detention indefinitely, arguing it had no choice as long as removal remained the legal obligation. Zadvydas filed a habeas corpus petition — the ancient legal tool for challenging unlawful imprisonment — arguing that holding him forever without any realistic prospect of deportation was unconstitutional. Kim Ho Ma faced a similar situation from a different direction. A Cambodian refugee who'd come to the United States legally, Ma was ordered deported after a criminal conviction. But the United States and Cambodia had no deportation agreement at the time, so Cambodia wouldn't take him back. The two cases were argued together. The Supreme Court decided 5-4 that the government couldn't detain people indefinitely simply because it couldn't find anywhere to send them. Writing for the majority, Justice Breyer read a time limit into the deportation statute to avoid what he called a "serious constitutional problem" — indefinite civil detention of someone who has lived in the country legally, without any criminal trial or dangerousness hearing.
The Question Before the Court
Can the federal government detain a legal immigrant indefinitely after a deportation order when no country will accept the person — or does the Constitution's protection of liberty require eventual release?
Petitioner
Zadvydas
Party asking the Court to review or reverse
Argued
- The statute plainly authorizes detention and sets no time limit
- Releasing dangerous criminals serves no constitutional purpose
- Deportation proceedings are civil, not criminal — different rules apply
- Courts shouldn't second-guess executive branch immigration decisions
Respondent
Davis
Party defending the judgment below
Argued
- Indefinite detention without any prospect of removal is punishment without trial
- The statute must be read to avoid a serious constitutional problem
- Even non-citizens who have entered legally have liberty interests the Constitution protects
- Habeas corpus must be available to challenge indefinite executive detention
The Holding
The Supreme Court ruled 5-4 that the immigration statute does not permit indefinite detention of people under final deportation orders when actual removal is not reasonably foreseeable. Justice Breyer wrote for the majority that the Fifth Amendment's protection of liberty applies to lawful permanent residents and that reading the statute to allow truly indefinite detention would raise a serious constitutional problem the Court preferred to avoid. The majority established a practical rule: six months of post-removal-order detention is presumptively reasonable. After that, if a detained person can show there is no realistic prospect of removal, the government must either produce evidence that removal will actually happen in the foreseeable future or release the person under supervision. The four dissenters—led by Kennedy and Scalia—argued that the statute clearly permitted indefinite detention and that courts had no business imposing judicially invented time limits on an immigration program Congress had authorized.

What this means for you
Limits the government's ability to hold removable noncitizens indefinitely when removal is not reasonably foreseeable: after roughly six months, detainees can seek release via habeas corpus unless the government can demonstrate a realistic prospect of removal; this protects individual liberty, shapes immigration-detention practice, and increases judicial review of long-term immigration detention.
Key Takeaways
- The government can't hold immigrants indefinitely just because it can't find a country to deport them to — after about six months with no realistic prospect of removal, courts can order release
- The Fifth Amendment's due process protection applies to people who entered the country legally, even after they've been ordered deported — constitutional rights don't simply switch off when immigration status changes
- The ruling created a practical tool: after six months of post-order detention, detained immigrants can go to court and challenge continued detention by showing removal isn't foreseeable
- This decision matters most for stateless people, refugees whose home countries won't take them back, and those whose countries lack deportation agreements with the United States
- The Court used a "constitutional avoidance" approach — reading a time limit into an ambiguous law rather than directly deciding whether indefinite detention violates the Constitution
