The Trump administration’s mass detention policy — enacted last summer and now used to jail thousands of people for months without bond hearings — has produced a federal court map in which most appeals courts have either ruled or are on the verge of deciding whether the policy is lawful, and lawyers and officials alike say the fight will likely end at the Supreme Court.
Michael Tan, quoted Wednesday, put the moment plainly: "I think it’s likely this issue will be resolved by the [Supreme] Court," as judges across the country approach competing decisions over the policy’s reach.
The policy orders some people accused of crossing the border without authorization into mandatory detention — a reading of a 30-year-old law known as the Illegal Immigration Reform and Immigration Responsibility Act, or IIRAIRA, that the administration describes as strict and sweeping. The policy has applied even to some people who have lived in the United States for years without incident, including some with work permits and no criminal histories.
By next week, judges in 11 of the 12 federal appeals circuits will either have ruled on the question or be considering arguments about it, a cadence that exposes a deep disconnect in the courts. Two appeals courts have so far ruled with the Trump administration; one appeals court sided with immigration detainees just last week; and a three-judge appeals court panel in the Seventh Circuit was divided three ways on the question on Tuesday as part of a larger case. The result is a clear circuit split.
The weight of the litigation also rests below the appeals courts. Several hundred district courts have considered habeas corpus petitions challenging the detentions — and the majority of those district courts have ruled against the administration. Those petitions, filed in large numbers across the country, argue that the detentions are unlawful and seek immediate release or bond hearings for people held without such hearings.
Federal officials have defended the program publicly. A DHS spokesperson said: "We are confident in our position, which a majority of courts of appeals have endorsed." Separately, the department said, "ICE has the law and the facts on its side and will be vindicated by higher courts." Those assertions sit uneasily beside the growing list of courts that have pushed back, and the fact that the D.C. Circuit is not on the active map — there is no immigration detention center in Washington, D.C., and so that circuit is not considering the mass detention policy.
The disagreement is grounded in legal interpretation. The administration relies on an extreme reading of IIRAIRA, a 30-year-old statute, arguing it requires mandatory detention for some people who have lived in the country for decades without incident by treating them as if they have just crossed the border. Opponents say that interpretation breaks with precedent and with the statute’s text, and they have pressed those arguments through habeas petitions at the trial level and on appeal.
The tension is stark: the majority of district courts have rejected the administration’s position, but at the appeals level the rulings are split, and several influential panels have sided with the government. That friction — a mix of conflicting circuit rulings and a torrent of lower-court losses for the administration — is the classic trigger for Supreme Court review.
Michael Tan, again speaking this week, framed the next steps plainly: "We’re very much still considering our options [to petition the Supreme Court], especially now that we have a circuit split." If challengers or the government files a petition, the Supreme Court would have the authority to resolve whether the administration’s mandatory detention interpretation of IIRAIRA stands.
The most consequential next move is procedural: which side files first, and whether the justices take the case quickly. Given the number of appeals circuits that will have issued decisions or heard arguments by next week, the legal path to the high court is clearer than it was months ago. The practical consequence — whether thousands of people now held without bond hearings will get review of their detentions — depends on that next procedural step and how the Supreme Court chooses to use its docket.
