Until last year, most would have fought deportation on bond after a brief hearing with an immigration judge. Now, their only hope of release is to file a petition for writ of habeas corpus — a legal maneuver once typically reserved for death row inmates and suspected terrorists — inundating the country's busiest federal courts with thousands of emergency suits.

The sanction came days after Nunley took the unusual step of announcing a "judicial emergency" in the district, which covers nearly half of California, stretching from the Oregon border to the Mojave Desert in the inland part of the state, including Fresno, Bakersfield and Sacramento.

In the last year, the Eastern District has received more petitions from immigration detainees than almost any other jurisdiction in the United States: more than 2,700 since January, compared to fewer than 500 last year and just 18 in 2024.
