本文就國際公約、大法官解釋、法律以及最高法院判決四個層面，對98年度國內刑事程序法制度產生重要影響之處為介紹、評論。國際公約方面莫過於《公民與政治權利國際公約》之簽署，以及其人權相關規定在我國生國內法律之效力，最直接之衝擊，為司法院急於速速通過「妥速審判法」以符合該公約之明文。在大法官釋字方面，共做成第654、665、664號與刑事訴訟制度相關之解釋，其中第654號解釋，將准許監聽羈押被告與律師的羈押法規定宣告違憲，確立刑事被告享有與其辯護人自由溝通的實質、有效權利，為刑事訴訟法非常重要的里程碑。判決方面，本文舉出最高法院二則與自白有關之判決，突顯其雖就自白之取捨無法形成理論圓融一致的理論思想。又舉出其上訴二審具體理由之判決，肯定最高法院針對往昔之非，能勇於面對積極改正。

The paper reviews and examines the important developments in Taiwan’s criminal procedural laws, especially focusing on the impacts of international conventions, Constitutional Court's decisions, newly amendments to statutes, and Supreme Court's decisions. Taiwan's legislature passed the International Covenant on Civil and Political Rights and International Covenant on Economic, Social and Cultural Rights on March 31, 2009. On December 10, the provisions in the two Covenants have the same effect as domestic laws. For this reason, Taiwan has drafted and passed the Speedy Trial Act in order to fulfill the requirements of the Covenants. For constitutional issues, the Constitutional Court held unconstitutional a long-term practice authorized by the law to videotape the conversations between the detainees and their defense lawyers. The taped conversation could even be used against the defendant at trial. The Court indicated that a defendant's constitutional right to lawyer allows him to enjoy the complete and free communication with his defense lawyer without fear of their communication might be admissible against him. As to the Supreme Court's decisions, this paper criticizes the Court's inconsistent theories toward laws on confessions. On the other hand, the justices have made significant progress to correct their previous wrong theories of blocking the channels for defendants to make a successful appeal.
