Abstract: The Power of Administrative Adjudication played an important part in settling civil disputes which is gradually replaced by the Power of Civil Adjudication. Because the number of civil cases increases sharply and the contents of civil cases are becoming more complicated, academic and judicial circles increasingly recongnize the limitation of the Power of Civil Adjudication and the importance of the Power of Administrative Adjudication. The supreme People's Court's judicial interpretations of the ADRs which is very important will enlarge the scope of the Power of Administrative Adjudication and narrow the scope of the Power of Civil Adjudication. Research on relation between the Power of Administrative Adjudication and the Power of Civil Adjudication may play a fundamental role in constructing a system of ADR.
