Due process
The term "due process" is unique to common law legal systems, and is not generally found in the text of international human rights and humanitarian law treaties. Due process is a powerful concept at common law, so it was important for the Lexington Principles to be phrased in those terms. All of the transnational norms discovered during the lengthy research phase of the Lexington Principles Project needed to be translated into aspects of due process. This was accomplished by distilling all points of mutuality in the law governing detainee treatment under both international law and domestic U.S. law down to one central right: the right to physical liberty. Principle 1 of the Lexington Principles on the Rights of Detainees codified this right, and all other rights were drafted as essentially derivative of this central guarantee.
