A ProPublica analysis of more than 70,000 habeas corpus petitions filed since January 2025 found that federal courts vary dramatically in how quickly they rule on whether immigration detainees are being unlawfully held. Courts in Mississippi and Louisiana, where some of the country's largest ICE detention facilities are located, have typically taken three months or more to decide cases, while courts in California, Texas, Florida, and Minnesota have resolved cases within weeks. Attorneys and advocates say the delays leave detainees waiting in prisonlike conditions, with some accepting deportation or voluntary departure rather than continue waiting for a ruling. Judges have used varying approaches, including standing orders, borrowed judges, and streamlined bond hearing procedures, to manage the surge in filings, while some courts, such as Mississippi's Southern District, have left the bulk of cases with a single judge amid mounting backlogs.
