摘要

本文探討我國刑法通姦罪構成要件行為－通（相）姦行為－之內涵，其中，特別就「口交是否成立通姦」此一命題提出學說及實務上之相關討論。雖然通姦除罪之聲浪於我國一直以來從未間斷，但在尚未除罪化之前提下，通姦罪於裁判實務上如何地被解釋，誠值討論。本文以近年裁判實務中一則認定「口交成立通姦」之刑事判決即臺灣高等法院高雄分院103年度上易字第107號刑事判決作為觀察對象，發現該則判決以司法院釋字第554號解釋為基礎，就通姦罪之處罰，作了有別於傳統實務認定通姦行為乃「男女性器接合」此一見解的兩個擴張：第一個擴張是，該判決對通姦行為之定義提出新的解釋即「足以侵害婚姻、家庭制度及社會生活秩序，而合於現行法律及一般社會共同生活規範所認知內涵之性行為者」；第二個擴張則是，其認為通姦罪之處罰對象亦擴及「同性」間之性行為。是本文即從司法院釋字第554號解釋、罪刑法定原則、構成要件明確性、保護法益等角度切入討論該判決可能的問題點並提出相關建議。

This article tries to explain and review the legal issue of the interpretation and application of Criminal Code of the Republic of China (Taiwan) Article 239 (hereinafter referred to as ＂Article 239＂), especially in the concept ＂adultery＂ from Article 239, and clarify a specific problem: ＂Is it adultery for a married male to receive oral sex from a non-married female?＂ One opinion that people may hold is that if there is no direct sexual intercourse, then it's not adultery. However, the criminalization or decriminalization of adultery has always been an important legal issue in Taiwan. Besides the constitutional interpretation made by J.Y. Interpretation No. 554, the judicial practice of decriminalization of adultery still needs further study. Therefore, this paper will explain the concept ＂adultery＂ of Article 239 and tries to analyze and clarify the standard and development of criminal judicial practice. Then, we examine the Taiwan High Court Kaohsiung Branch Court Judgment Shan-Yi-Zi No. 107 (2014) by these standards. And we can find that the aforementioned judgment has totally misunderstood the interpretation and application of the concept ＂adultery＂ from Article 239 and J.Y. Interpretation No. 554 in its judgment. In the last part, this paper will make some criticisms and suggestions.
