Mohsen Mahdawi speaks to a Globe reporter in Fairlee, Vermont, May 7, 2025. The detention in March of Tufts doctoral candidate Rumeysa Ozturk was captured on a video that depicted a man in a hoodie stopping her on a street in Somerville, Massachusetts. They called it “a shocking violation of the First Amendment.”The federal government is appealing a lower court decision granting Ozturk release on bail while her immigration case is pending. In both cases, the government argued that no federal court can hear a habeas challenge until the administrative immigration review process runs its course. Mahdawi’s attorneys, and Ozturk’s attorneys, argued nothing in federal law allows for indefinitely detaining noncitizens before they can appeal the constitutionality of their detention.
