Hamdan v. Rumsfeld (2006), brought by Neal Katyal, produced one of the Supreme Court’s most consequential wartime rulings, striking down the military commission system at Guantanamo Bay and reaffirming constitutional limits on executive power. Katyal went on to serve as Acting Solicitor General and by 2017 had argued before the Supreme Court more times than any other minority attorney in American history. In 2025, he argued before the Supreme Court against a sitting president’s executive order on birthright citizenship, cementing his place among the nation’s foremost Supreme Court advocates.
