The concept of due process was formally put forward in the form of theoretical system in the modern West, but there must be a consideration of whether the procedure itself is reasonable and just since the establishment of the dispute settlement procedure in human society. Although this consideration may be primitive and non-systematic, it still has room for reference and thinking for us to explore the theory of due process. This paper analyzes the concept and practice of due process in dispute resolution in primitive society and Greek society in order to have a more intuitive and systematic understanding of the judicial situation at that time.
