Whether the crime was consummated or merely attempted greatly changes the severity of the sentence.
裁判所(さいばんしょ)は被告(ひこく)の行為(こうい)を強盗(ごうとう)既遂(きすい)と認定(にんてい)し、懲役(ちょうえき)十年(じゅうねん)を言(い)い渡(わた)した。
The court found the defendant's act to be consummated robbery and sentenced him to ten years in prison.

Composed of 既(き) (already) and 遂(すい) (to accomplish; to carry through). Literally "already accomplished," contrasted with 未遂(みすい) "not yet accomplished."

Usage

A specialized legal term. Most commonly appears attached to the name of a specific crime: 殺人(さつじん)既遂(きすい) (consummated murder), 強盗(ごうとう)既遂(きすい) (consummated robbery), 詐欺(さぎ)既遂(きすい) (consummated fraud). Virtually never used outside legal and crime-reporting contexts. The distinction 既遂(きすい) vs. 未遂(みすい) is important because Japanese criminal law allows lighter sentences for attempted crimes.
