But there’s another path to holding ICE and CBP accountable for abuses. As a federal agency, the Department of Homeland Security is subject to the dictates of federal administrative law, much of which is set forward in a powerful 1946 statute known as the Administrative Procedure Act. The APA is largely concerned with how agencies go about their business—setting forward, for instance, how they should issue regulations and resolve administrative disputes. The statute also allows courts to review potentially unlawful action, thereby ensuring agencies follow the Constitution, other federal laws, and their own rules and procedures.
