About this publication
Writ of Habeas Corpus is an editorial chronicle of how the oldest civil-liberties remedy in Anglo-American law—the writ codified at 28 U.S.C. § 2241—is being deployed in the contemporary U.S. immigration system.
For most of the twentieth century, immigration habeas was a sleepy corner of the federal docket. After the 1996 IIRIRA reforms, the 2001 decision in Zadvydas v. Davis, and the post-2018 wave of Jennings follow-ons, that quiet corner became one of the most contested precincts in federal court. By 2025, with the second Trump administration's reinvocation of the Alien Enemies Act and the Bureau of Immigration Appeals's reclassification of millions of long-resident noncitizens as "applicants for admission" ineligible for bond, immigration habeas had become the principal mechanism by which federal courts review the legality of executive detention.
What we cover
This site publishes a separate piece of commentary on every consequential federal habeas ruling in the immigration context, organized into the doctrinal categories that practitioners actually use: pre-removal mandatory detention under § 1226(c) and § 1225(b); post-removal detention under § 1231(a)(6) and the Zadvydas framework; the Alien Enemies Act docket of 2025; the third-country removal litigation; the First Amendment student-detention cases; and the procedural and doctrinal pivots—jurisdictional zipper-clause questions, EAJA fee availability, BIA precedent shifts—that shape every petition.
Editorial approach
Each article opens with a black-letter case panel: citation, court, judge, statute, holding. The body then explains the facts, situates the ruling within the existing doctrinal landscape, and assesses the practical significance for habeas practice. We aim to be useful to lawyers, law students, judges, and serious lay readers—and to be honest about disagreement among the circuits where it exists.
We do not endorse outcomes or causes. We try to describe what courts actually held and why it matters.
About the editorial team
Articles are published under a collective Editorial Team byline. We draw on primary opinions, official court PDFs, the Civil Rights Litigation Clearinghouse, the National Immigration Litigation Alliance practice advisories, the American Immigration Council, the National Immigration Project, and other reputable secondary sources. Where we cite a court's words directly, we identify the court and the page. Where there is genuine doctrinal uncertainty, we say so.
