Pro-Palestinian activist Mahmoud Khalil will appeal his case to the U.S. Supreme Court following a federal appeals court decision on Friday that rejected his request for a rehearing in his detention case.

The appeals court ruling means Khalil must now pursue his constitutional claims through the immigration appeals process after receiving a final removal order. The decision represents the latest development in Khalil's ongoing legal battle against deportation proceedings.

Khalil became a prominent figure during what sources describe as increased enforcement actions against pro-Palestinian protesters. His case has drawn attention as part of broader immigration enforcement policies affecting activists.

The Supreme Court appeal represents Khalil's next legal avenue to challenge his detention and potential deportation. The case involves constitutional claims that Khalil's legal team argues should be heard in federal court rather than through immigration proceedings.

The timeline for the Supreme Court appeal process remains unclear, as the high court receives thousands of petitions annually and accepts only a small percentage for full review. Khalil's legal team will need to file a petition for writ of certiorari to request Supreme Court consideration of the case.
