Habeas Corpus Petitions Surge in Arizona Amidst Detention Policy Changes

Arizona courts are experiencing an unprecedented increase in habeas corpus petitions due to new policies that expand mandatory detention for immigrants and restrict traditional bond hearings. This shift has moved a significant number of detention challenges into federal court, creating a substantial caseload for the District of Arizona. The situation highlights a broader change in how immigration detention cases are being handled nationwide.

The Rise of Habeas Corpus Petitions

Following a policy change in July 2025, which reclassified immigrants entering without inspection as applicants for admission, many noncitizens became subject to mandatory detention. This reclassification meant they could be detained regardless of how long they had been in the United States. A subsequent ruling in September 2025 by the Board of Immigration Appeals, Matter of Yajure Hurtado, further complicated matters by stating that immigration judges do not have the authority to grant bond to this reclassified group.

This effectively closed off the usual path for detainees seeking release through bond hearings. As a result, individual habeas corpus petitions filed under 28 U.S.C. § 2241 became the primary legal recourse for challenging detention. Data from October 2025 through March 2026 shows that the District of Arizona alone received 1,104 such petitions. Nationwide, immigration-related habeas lawsuits saw an increase of over 85 times compared to 2025 levels.

Government Response and Justification

Officials from the Department of Homeland Security (DHS) have characterized the new approach as a return to a stricter interpretation of immigration law. Secretary of Homeland Security Kristi Noem stated on May 20, 2026, that habeas corpus is a constitutional right that supports the president’s authority to remove individuals from the country. She also acknowledged the president’s power to decide if this right should be suspended.

Alejandro Almeida, Deputy Field Office Director for ICE-ERO Phoenix, defended enforcement actions in Arizona, directing detainees to available review processes. He emphasized the importance of programs like the Criminal Alien Program in identifying and arresting individuals. Zach Kahler, a USCIS spokesman, explained on May 22, 2026, that the policy aims to make the immigration system function as the law was originally intended, rather than encouraging loopholes.

Impact on the Court System

The overwhelming volume of habeas corpus filings has placed a significant strain on the U.S. District Court for the District of Arizona. On February 19, 2026, the court took the unusual step of provisionally appointing the Federal Public Defender to represent indigent detainees in these habeas cases. This measure was intended to help manage what the court described as a deluge of legal challenges.

Arizona judges have also expressed frustration with the burden of handling individual cases that once would have been resolved through bond calendars. The current system requires each petition to be filed, reviewed, and adjudicated separately, adding to the workload. This situation reflects a structural change where custody disputes are now processed through federal habeas review, with each detainee filing their own case.

Detention Conditions and Oversight

Concerns about conditions within detention centers have added urgency to these legal battles. Senators Mark Kelly and Ruben Gallego have called for a halt to detention expansions, citing overcrowding and “inhumane and deeply troubling” conditions at facilities in Surprise and Marana, including the Mesa ICE facility. The number of deaths in custody has also become a factor in the court cases. ICE reported 16 deaths in the first few months of 2026, following a record 50 deaths in 2025. These statistics underscore the human impact behind many of the habeas corpus filings, where detainees argue that prolonged detention without a bond hearing violates fundamental protections.
