In its upcoming term, the Supreme Court will decide whether ICE has the authority to detain without bond all noncitizens who have entered the country without legal admission even if they have lived in the United States for decades. Sections 1225 and 1226 of U.S. Code Title 8 outline the detention procedures for noncitizens. Historically, § 1225 has been interpreted to apply to noncitizens who are apprehended when they are just entering the country, while § 1226 has been interpreted to apply to noncitizens who are apprehended within the country. In 2025, ICE announced a new interpretation of § 1225, asserting that it mandates the detention of all noncitizens in the country who were not officially admitted, regardless of how long they have been in the United States. This is a radical change from long-standing practice and a mischaracterization of the statute. Subjecting all noncitizens who have not undergone immigration inspection to mandatory detention is not authorized by the statute’s text or legislative history, and such an interpretation poses significant constitutional concerns. Courts across the country have heard challenges to this new interpretation of § 1225 and have split over the issue, leading the Supreme Court to grant certiorari earlier this month. The majority of district and circuit courts have reached the correct conclusion: Section 1225, with its mandatory detention provision, should only apply to noncitizens who have not yet entered the country, and Section 1226, which permits bond hearings, should apply to noncitizens living in the country.
