The act of state doctrine is a court-made (common law) doctrine that prohibits U.S. courts from judging the validity of the official acts of a foreign country that take place within that foreign country's borders.
In Alabama, as in other U.S. states, the act of state doctrine is recognized as a principle of law that originates from federal common law rather than state statute. This doctrine holds that U.S. courts will generally refrain from evaluating the legality of governmental actions taken by a foreign sovereign within its own territory. The rationale behind this doctrine is to respect the sovereignty of foreign nations and to avoid conflicts in foreign relations that could arise from the judicial assessment of such actions. While the act of state doctrine is not codified in Alabama state statutes, it is applied by federal and state courts in Alabama in accordance with U.S. Supreme Court precedents and federal common law. It is important to note that there are exceptions to the doctrine, such as when a U.S. statute or treaty explicitly indicates that certain foreign acts may be subject to judicial scrutiny.
