Rasul v. Bush
The Court ruled that foreign nationals held at the Guantanamo Bay Naval Base could file habeas corpus petitions in U.S. federal courts, rejecting the government's argument that federal courts had no jurisdiction over noncitizens detained outside the United States.
The decision opened federal courthouse doors to hundreds of foreign detainees captured in the war on terror, marking an early and significant check on executive power to hold people indefinitely without any judicial review.
“We therefore hold that § 2241 confers on the District Court jurisdiction to hear petitioners' habeas corpus challenges to the legality of their detention at the Guantanamo Bay Naval Base.”
The majority's core holding that federal courts have habeas jurisdiction over the Guantanamo detainees' claims.
How it got here: A federal trial court dismissed the detainees' habeas claims for lack of jurisdiction; the D.C. Circuit affirmed; the detainees asked the Supreme Court to review.
The Case in Depth
What happened
After the September 11 attacks, the U.S. military captured foreign nationals abroad during the war in Afghanistan and detained many at the U.S. naval base in Guantanamo Bay, Cuba. Fourteen detainees — two Australians and twelve Kuwaitis — said they had never fought against the United States and had never been charged with wrongdoing or given access to lawyers or courts. They sued for release and other relief.
The question before the Court
Could foreign nationals captured abroad and held at the Guantanamo Bay Naval Base use U.S. habeas corpus law to challenge their detention in American courts?
The Court's answer
Yes — the Court ruled that federal courts do have jurisdiction to hear habeas corpus petitions from foreign nationals held at Guantanamo Bay, even though they are not U.S. citizens and are held outside the sovereign territory of the United States. The Court found that the earlier case the government relied on, Johnson v. Eisentrager, did not control here, because that case involved enemy nationals already convicted by a military tribunal, and because a later decision, Braden v. 30th Judicial Circuit Court, had already undercut the statutory reasoning underlying Eisentrager's result.
Because the United States exercises complete practical control over Guantanamo Bay and the habeas statute does not distinguish between citizens and noncitizens, the Court held that the detainees' custodians could be reached by legal process, giving federal courts jurisdiction. The case was sent back to the lower court to decide the actual merits of the detainees' claims.

Why it matters
Guantanamo detainees and their lawyers could now bring habeas challenges in federal court rather than being left entirely to military and executive discretion. The ruling set the stage for years of follow-on litigation over what rights terrorism suspects held at Guantanamo actually have, with lasting consequences for how the U.S. detains people during wartime.
What changes now
The case was sent back to the district court to consider the merits of the detainees' claims for the first time, since the Supreme Court decided only the jurisdictional question. Guantanamo detainees could now file habeas petitions challenging their detention, and this decision opened the door to years of further litigation over detainee rights, procedures, and the scope of executive detention authority in later cases.
What this does not decide
The Court decided only that federal courts have jurisdiction to hear the detainees' habeas claims — it did not decide whether their detention is actually lawful, what legal process they are entitled to, or the merits of any individual detainee's case, leaving those questions for the district court on remand.
Concurrences and dissents
Concurrence — Justice Kennedy
Justice Kennedy agreed that federal courts have jurisdiction but would have reached that result by applying the Eisentrager framework itself rather than relying on Braden. He argued Guantanamo is practically a U.S. territory far from any battlefield, and that indefinite detention without any legal proceeding to determine status is far weaker grounds for excluding judicial review than the situation in Eisentrager, where prisoners had already been tried and convicted.
Dissent — Justice Scalia
“This is not only a novel holding; it contradicts a half-century-old precedent on which the military undoubtedly relied, Johnson v. Eisentrager, 339 U. S. 763 (1950).”Scalia's central objection that the majority is overturning settled precedent the military relied on.
Justice Scalia argued the habeas statute plainly requires that a detainee be held within some federal district court's territorial jurisdiction, which Guantanamo is not. He contended the majority's claim that Braden overruled Eisentrager's statutory holding is implausible, since Braden never even mentioned Eisentrager and dealt with a different situation entirely. He would have left any expansion of habeas rights to Congress and warned the ruling would flood courts with claims from detainees worldwide.
How the Court got there
The legal reasoning, step by step
- The Court examined its 1950 decision in Johnson v. Eisentrager, which had found no habeas jurisdiction over German war criminals held abroad, and identified key facts that made that case different — including that the Eisentrager prisoners were enemy nationals who had already been convicted by a military tribunal.
- The Court explained that jurisdiction turns on the wording of the habeas statute, which lets district courts hear cases from anyone in custody 'within their respective jurisdictions,' and that a later decision, Braden v. 30th Judicial Circuit Court, had already held that a court has jurisdiction over a habeas petition as long as the jailer can be reached by legal process, regardless of where the prisoner is physically held.
- Because Braden undercut the earlier rule in Ahrens v. Clark that required the prisoner's own physical presence within a court's territory, the Court concluded that the statutory basis underlying Eisentrager's outcome no longer held, so Eisentrager did not control this case.
- The Court rejected the government's argument that the presumption against extending federal statutes overseas should bar the detainees' claims, noting that the United States exercises 'complete jurisdiction and control' over Guantanamo Bay under its lease agreements with Cuba, distinguishing the base from ordinary foreign soil.
- Concluding that the habeas statute draws no distinction between citizens and noncitizens held in U.S. custody, and that the detainees' custodians were within reach of U.S. courts, the Court held that federal habeas jurisdiction extended to the Guantanamo detainees' claims.
Doctrinal impact
Cases affected by this decision
Limits Johnson v. Eisentrager (339 U.S. 763)
The Court held Eisentrager's facts and reasoning don't bar habeas jurisdiction over the Guantanamo detainees.
Abrogates Ahrens v. Clark (335 U.S. 188)
The Court treated Ahrens' rule requiring a detainee's physical presence in a court's territory as no longer good law after Braden.
Reaffirms Braden v. 30th Judicial Circuit Court of Ky. (410 U.S. 484)
The Court relied on Braden's rule that jurisdiction exists wherever the custodian can be served with process.
