By mid-January 2026, ICE held a record 73,000 people in immigration detention—a number that had grown dramatically over the previous year.
On February 6, 2026, the Fifth Circuit Court of Appeals became the first appellate court to uphold the Trump administration’s practice of detaining noncitizens without bond hearings. The decision permits indefinite detention during removal proceedings for people who entered without inspection—no hearing, no individualized assessment, no opportunity to show they’re not a flight risk.
The constitutional rule of due process applies regardless of how Congress writes detention laws. It protects “persons,” and noncitizens physically present in the United States are entitled to constitutional protection.
Even if the court’s reading of the law holds up, constitutional guarantees remain—guarantees that federal courts across the country are already enforcing, despite what one appellate panel said.
The Constitutional Baseline
Physical presence in U.S. territory triggers legal rights that protect you, regardless of what the government says.
The administration argues that “mandatory detention” means exactly what it says—detention is mandatory, period, until removal proceedings conclude. No bond hearings. No periodic review.
That interpretation violates constitutional limits the Supreme Court has established repeatedly. You can’t detain people indefinitely without some procedural check, some opportunity to contest whether detention remains necessary. The government’s efficiency interests don’t override the fundamental liberty interest in freedom from confinement.
What Due Process Requires
Imprisonment—or indefinite detention without possibility of release—affects what the Supreme Court calls the most fundamental freedom protected by the Due Process Clause. Someone facing six months, a year, or longer in immigration detention loses freedom of movement, separation from family, ability to work, connection to community.
The government argues that immigration detention is “civil” (not criminal punishment), so fewer protections apply. Calling it ‘civil’ instead of ‘criminal’ doesn’t change the fact that you lose your freedom.
For nearly three decades—from 1997 until 2025—both Republican and Democratic administrations allowed detained noncitizens to request bond hearings before immigration judges. Judges evaluated whether the individual posed a flight risk or danger to the community.
The new mandatory detention policy eliminates this individualized assessment entirely for people classified as “applicants for admission.” No immigration judge will ever conduct a hearing to determine whether that particular person needs to be detained. For immigrants who’ve lived here for years with family and jobs, locking them up without a hearing risks wrongly taking away someone’s freedom.
Immigration judges have been conducting bond hearings since 1997 without the system collapsing.
Even if Congress explicitly allowed mandatory detention, courts must read the law in a way that avoids serious constitutional problems.
The Entry Fiction Extended Inland
Courts have long used a legal concept called the “entry fiction”—the idea that someone arriving at a port of entry occupies a different constitutional position than someone who has already entered U.S. territory, even though the port of entry is physically located within the United States.
This concept made sense at the border, where officials need to act quickly. A person stopped at an airport faces basic initial questions: Can you enter? Do you have valid documents? Do you pose a security risk?
The Fifth Circuit extended this concept to people arrested inland, years after they arrived. The court ruled that someone detained in Houston or Chicago can be reclassified as an “applicant for admission” simply because they weren’t formally admitted when they crossed the border—even if they entered years earlier, even if they’ve built lives here with U.S. citizen children.
Someone arrested in the interior after living in the United States for years faces an entirely different situation than someone stopped at customs. That inland detainee is already under full U.S. court authority, has community and family ties, and faces removal hearings more like a lawsuit than a quick border check.
The Supreme Court recognized this in Plyler v. Doe: once someone is physically in the United States, they get substantial constitutional protections.
The constitutional question is whether the government can lock up someone who’s been living here for years, based only on how they entered, without a hearing about their specific situation. Based on Supreme Court precedent, the answer should be no.
Constitutional Protections That Remain
When an immigration judge can’t hold a bond hearing—as the Fifth Circuit now allows—several constitutional protections still exist.
The most powerful protection is federal habeas corpus—a constitutional right to challenge unlawful detention in federal court. This right applies to noncitizens, including undocumented immigrants. When an immigration judge won’t hold a bond hearing, federal courts can still review whether the detention violates the Constitution.
Courts across the country have consistently ordered release or bond hearings, even though the Fifth Circuit ruled the opposite. According to a news review, at least 360 federal judges have rejected the mandatory detention policy in over 3,000 cases, while only 27 judges supported it in about 130 cases.
Federal judges outside the Fifth Circuit see this detention policy as raising serious constitutional problems that can’t be fixed by what the law says.
Detained immigrants can hire a lawyer—though the government doesn’t have to pay for one in immigration cases like it does in criminal cases. Research shows detained immigrants with lawyers are four times more likely to be released and ten times more likely to avoid deportation.
The right to present evidence, question government witnesses, and testify remains protected. An immigration judge must still decide if the government has proven the person should be deported, and the government must prove it with strong evidence.
Noncitizens can also go to court to demand better detention conditions. While detention itself may continue without a bond hearing, the conditions can’t be punitive or inhumane. The government must provide adequate food, medical care, sanitary facilities, and access to lawyers and legal documents. Deaths in immigration detention have risen sharply in recent years, prompting investigations and lawsuits over poor conditions and medical neglect.
ICE can release people early if it decides to, for humanitarian or family reasons. While not required to, ICE can release people on parole for humanitarian reasons, family unity, or public benefit.
Constitutional Limits on Detention Duration
Even if the government can temporarily detain immigrants while deciding whether to deport them, there are constitutional limits on how long this can last.
The Supreme Court has ruled that indefinite detention violated the Constitution because freedom from imprisonment is a fundamental right. The traditional reasons for detention—preventing someone from fleeing and protecting the community—don’t apply when deportation seems unlikely or impossible.
Many people detained without bond hearings haven’t been ordered deported yet. They’re detained while their deportation cases are still ongoing, which can take months or years. Federal courts have extended similar protections to detention before a deportation order, recognizing that the same constitutional concerns apply.
As of June 2024, ICE held more than 59,000 people in detention—42 percent more than the 41,500 beds the federal government funds. By mid-January 2026, that number had jumped to a record 73,000—approximately 24 percent more than the June 2024 figure. The Trump administration has secured funding to expand detention capacity to 116,000 beds—more than two and a half times the original capacity.
When detention capacity expands without legal protections, people spend longer in detention. Detainees report waiting months for their deportation cases to start, then months more for hearings, resulting in a year or more in detention with no chance to challenge it.
How Other Democracies Handle Immigration Detention
The European Convention on Human Rights requires all EU member states to give due process protections to everyone in their territory. The European Court of Human Rights requires that detention be based on clear law and that it be necessary for a legitimate purpose.
Europe requires a case-by-case decision about whether each person needs to be detained, not automatic detention based on immigration status. While European states can detain immigrants awaiting deportation, they must regularly review the detention and let people challenge it.
Canada’s Immigration and Refugee Protection Act requires detention decisions to be based on necessity, with hearings within 48 hours, then every seven days, then at least monthly. Canadian officials must consider other options and whether the person might flee or pose a danger.
Canadian law assumes detention needs a reason and checks that reason regularly. The Fifth Circuit decision permits categorical mandatory detention with no regular review.
Australia similarly requires case-by-case decisions and release if detention is no longer needed, despite being known for strict immigration rules.
What the Supreme Court Might Do
The Fifth Circuit’s decision is expected to reach the Supreme Court, as similar cases are being challenged in courts across the country. The huge disagreement—360 judges rejecting the policy versus 27 supporting it—is exactly the kind of conflict that typically prompts the Supreme Court to take a case.
When the Court addresses this question, it will face several distinct constitutional issues. The most fundamental issue is what due process requires before the government can detain someone waiting for a deportation hearing.
The Fifth Circuit based its decision mainly on how it interpreted the immigration law as clearly requiring detention. The Supreme Court has made clear that reading a law can’t override constitutional limits.
If the Court addresses the constitutional question directly, it will probably ask whether detention without a hearing violates the Constitution. The government’s interest in deporting people quickly, while legitimate, doesn’t outweigh the fundamental right to freedom, especially since bond hearings were shown to work before.
A third question concerns the difference between detention at the border and detention inland. If the Supreme Court agrees that the Fifth Circuit wrongly treated inland residents the same as border arrivals, it could rule that people detained inland after years of living here must get different protections than those briefly detained at the border.
Lawyers will ask the Supreme Court to take the case, likely within 90 days. The Court typically takes several months to decide whether to hear the case, possibly by June 2026 or later. If the Court takes the case, it would likely be argued in fall 2026 or early 2027. The Court would rule by June 2027.
Meanwhile, thousands more immigrants will be detained, and many will win legal challenges in federal courts outside the Fifth Circuit, creating uneven protection depending on location.
Constitutional Protections Under Pressure
The Fifth Circuit’s February 2026 decision significantly changes how one court reads immigration detention laws. It’s not the final answer on what the Constitution requires.
Throughout American history, when courts have tried to let the government control immigration without legal limits, the Supreme Court has ultimately required constitutional protections. The Court has consistently ruled that being physically in the U.S. triggers constitutional protections that laws can’t take away.
For the thousands of immigrants currently detained without bond hearings, federal courts can still review detention through legal challenges. The difference between border and inland detention still matters.
The detention policy raises a deeper constitutional question: can the government lock up people inland, away from families, without letting them show they’re not a danger and won’t flee?
The Fifth Circuit answered yes, reading the law strictly. The Supreme Court’s past rulings suggest the answer should be no—or at least that some legal protection, some chance to be heard, and some time limit must apply to any detention.
Federal courts continue to approve legal challenges. Immigration judges in other parts of the country continue to hold bond hearings. Detained people continue to fight in court. The Supreme Court’s decision, likely in the coming months, will ultimately determine whether the constitutional protections that have protected immigrants for over a century still apply.
