A US immigration judge has rejected efforts by President Donald Trump’s administration to deport Columbia University student Mohsen Mahdawi, who was arrested ​last year following his participation in pro-Palestinian protests. Lawyers for Mahdawi detailed the immigration judge’s decision in a court filing on Tuesday with a federal appeals court in New York, which had been reviewing a ruling that led to his release from immigration custody in April.

It was the latest case in which an immigration judge rejected a case brought as part of the broader ‌effort by Trump’s administration ‌to detain and deport non-citizen students ​with pro-Palestinian ‌or ⁠anti-Israel ​views who ⁠engaged in campus activism.

Chelmsford, Massachusetts-based Immigration Judge Nina Froes wrote in a February 13 decision that the US Department of Homeland Security failed to meet its burden of proving he was removable, which it sought to do using an unauthenticated document signed by Secretary of State Marco Rubio. “This decision is an important step toward upholding what ⁠fear tried to destroy: the right to speak ‌for peace and justice,” Mahdawi said ‌in a statement.

The department did not immediately ​respond to a request for comment. ‌The administration has the option of challenging the judge’s decision ‌before the Board of Immigration Appeals, part of the US Department of Justice.
