大法官釋字第 585 號解釋已確認立法院具有調查權，然因尚未法制化，所以在立法實務上，立法院目前仍是依立法院職權行使法第四十五條規定成立調閱委員會或調閱專案小組，並未真正落實國會調查權之行使。主要原因與我國之憲政體制不無關連，而在調查權法制化之過程中仍有相當困境須逐一面對，也有一些瓶頸須逐步克服，才能突破相關立法障礙以完成法制化。 本文先談我國憲政體制之發展，並就調查權與法制化之完成、政黨輪替與調查權法制化之關聯及立法院「決議」與「法律保留」等三個面向論述調查權法制化所面臨之困境。再分別就充分利用協商制度、少數黨調查提案權的保障及與監察院的權責分屬關係等三個問題點，說明法制化過程所需突破之瓶頸，最後並就在野黨癱瘓議事，不利於法制化之原因加以分析。
