In one of the most important recent constitutional law cases, the United States Supreme Court handed down judgement in Boumediene v Bush, finding that the denial of habeas corpus to Guantanamo Bay detainees was unconstitutional. Adam Zellick was junior counsel on the amicus brief on behalf of petitioners explaining that the petitioners would have the right to habeas corpus under English law (and under common law at the time of the framing of the Constitution). This was Adam’s third brief before the US Supreme Court having previously acted in Rasul v Bush and Hamdan v Rumsfled.
