As Alex Aleinikoff stated in this forum recently, there will be much to report about Donald Trump’s Executive Orders relating to immigration enforcement and refugees in coming months. Given that the President recently issued an amended immigration order on 6 March, it is timely to reflect not only upon the legality of the order itself, but also upon the broader question of the role of the bureaucracy in carrying out any new order. As readers will know, President Trump’s executive immigration order issued in January attracted protest and litigation. In States of Washington and Minnesota v. Trump the U.S. District Court for the Western District of Washington granted a temporary injunction against the operation of the order, and the 9th Circuit refused to stay that injunction. Although the President has now rescinded that order, litigation on this matter looks set to continue with the Legal Director of the American Civil Liberties Union (ACLU) indicating that it will challenge the revised order in the courts.
