The New York Times reports that Adham Amin Hassoun has filed a petition for a writ of habeas corpus challenging his current detention in an immigration facility in Buffalo, New York. Hassoun, a Palestinian who later moved to Florida, was detained in 2002 for overstaying his visa and convicted on material support charges in 2007. After serving his criminal sentence, he was then held in immigration detention. A previous habeas petition led to a judge ordering his release in 2018 while the Trump administration sought to identify a country to which to deport him, but the administration then invoked a regulation to detain Hassoun indefinitely pending his final removal. The habeas petition, the first such challenge of that authority, is available in full here and below.
