2009年12月10日「公民與政治權利國際公約」與「經濟社會文化權利國際公約」透過「兩公約施行法」方式,在我國生效實施以來,對現行刑事實務產生相當影響,其中尤以死刑的裁量最為顯著。除了最高法院開啟死刑言詞辯論程序外,也在歷次判決下,逐漸建立起死刑裁量的初步基準。就其內容,除公政公約第6條的「最嚴重犯罪」概念與正當程序保證要求外,作為未來事實審裁量死刑時,應如何考量的諸般因素,融合到既有量刑理論與基準,也成為一個待檢討問題。本文嘗試觀察現有最高法院判決,並從檢討兩公約與日本實務量刑基準作為出發,就我國死刑仍存續的情況下,結合量刑理論上對各個量刑因子的解釋,在符合兩公約與量刑理論應然要求下,提出可供實務參考與操作的死刑裁量的方法,並探究其界限。
