國會調查權之目的就在於蒐集相關議案的資料及口頭或書面意見，除了釐清議案或人事案件外，更為了達到瞭解影響社會公益事件真相之目的，應將調查程序合理化，真正讓行政機關受到監督。國會調查權係民主國家立法機關不可或缺的輔助性權力，以確保其在立法時能夠獲得周延的資訊。而我國國會的調查權強制力相當有限，實在難以說服民眾相信或期待調查的結果可以完全發揮監督效用。其實我國國會的監督權限相關廣泛，但不夠細膩，例如立委有質詢權、調閱權、舉行公聽會的權利、倒閣權、彈劾罷免權及司法、考試、監察等三院的重要人事的任命同意權，但卻因為沒有針對程序、範圍及效果等正當立法。鑒於目前我國立法院的國會調查權遲未發揮如西方國家國會捍衛人民知的權利，以及目前立法院職權行使法修正草案規劃不全的情況下，希望能夠藉由立法院調查權法制化之探討，分別就「立法院職權行使法修正草案」與「立法院調查法草案」擬具修法意見，並分析二項法案在立法上的優缺點，提出我國國會調查權在法制上的立法建議，以符合大法官釋憲主旨。

In fact, the legislative Yuan has extensive supervisory authority, but not exquisite enough. For example, the legislators have the power of
