This paper focuses on a trial (an appeal hearing) for the Dotonbori murder case which took place in Osaka, Japan in 1995. The point at issues of the trial was whether the victim was thrown into a river by defendant or he accidentally fell.
Finally, the court considered the defendant's testimony telling his unhappy life so far as worthy of mitigating circumstances. The court commuted his six years imprisonment penalty to four years.
This paper aims to clarify some process of this commutation. The author explain how a fact that the victim by accident fell recognized as a "truth", instead of a fact that defendant threw him into a river.
