本文探討我國重罪羈押及司法院釋字第665號解釋於刑事訴訟學理上之相關問題。司法院釋字第665號解釋提出重罪羈押「相當理由」此一概念限縮重罪羈押制度之適用及判準,然而,我國於刑事訴訟學理上就此為文予以討論者確屬較為少數,而近年來司法實務如何就重罪羈押「相當理由」此一由司法院釋字第665號解釋提出的新概念予以操作於具體個案中,當屬重要議題,亦值得進一步研究、討論。因此,本文以臺灣臺北地方法院102年度聲字第2870號刑事裁定為評析對象,並以司法院釋字第665號及重罪羈押制度為核心,就重罪羈押「相當理由」要件、重罪羈押法律適用關係,以及我國實務就重罪羈押「相當理由」概念之描繪等概念,作更進一步的說明及重新檢視,並藉此評析本案將羈押學理依據錯置之相關問題。
This article tries to explain and review the legal issue of criminal felony detention, especially the concept of "probable cause" from J.Y. Interpretation No. 665. In fact, after the constitutional interpretation made by J.Y. Interpretation No. 665, the judicial practice of the criminal felony detention still needs further study.Therefore, this paper will explain the concept "probable cause" of the criminal felony detention in judgments made after J.Y. Interpretation No. 665 and tries to analyze and clarify the standard, change, and development of judicial practice. Then, we examine the Taiwan Taipei District Court Decision Sheng-Zi No.2870 (2013) by these standards. And we can find that the aforementioned decision has totally misplaced the detention theory in its decision. Lastly, this paper will make some criticisms and suggestions.
