Mahmoud Khalil petitions US Supreme Court to hear his free speech case

Mahmoud Khalil has filed a petition to the US Supreme Court to hear his case regarding free speech rights. The legal issue centers around the government's attempt to prevent a federal judge from intervening when free speech rights are curtailed. Should the Supreme Court decide to take up the case, it could have significant implications for noncitizen US residents caught up in the Trump administration's pro-Palestine speech-related immigration crackdown.

Khalil's petition argues that the US Immigration and Nationality Act does not prohibit federal courts from reviewing habeas claims challenging punitive or retaliatory detention. A federal judge released Khalil from immigration detention in June 2025 after more than three months in custody, ruling that the Trump administration's use of a foreign policy threat provision to arrest him was vague.

The case has already gained attention due to Khalil's immigration case being handled by Department of Justice officials, while immigration cases are typically handled by immigration judges who work independently. Khalil's attorneys argue that the federal courts can address this unconstitutional executive action through the writ of habeas corpus.
