According to the Constitution of the Republic of China, its Additional Articles, the Control Act and other related statutes, the Control Yuan is empowered to exercise the powers of impeachment, censure and corrective measures. In order to make these powers effective, the Control Yuan is given the power to conduct investigations.
The Control Yuan’s investigations can be divided into three categories: commissioned investigations, assigned investigations and self-initiated investigations. Commissioned investigations are those which entrust related organizations to investigate public complaints. Assigned investigations are those in which members, in rotation, are assigned by either the Control Yuan or by committee resolution to carry out an investigation. Self-initiated investigations are those in which members, acting on the basis of public complaints or other information, initiate investigations of their own accord.
