Supreme Court held that stabbing with a sharp object causing a 9cm wound constitutes a serious assault.

The Supreme Court determined that the defendant's act of stabbing victim B with a sharp object, resulting in a 9cm cross wound on the ceiling, constituted a serious assault. The prosecution argued the injury severity met the threshold for serious harm, while the defense contested the classification based on the location and nature of the wound. The court ruled that the depth and length of the laceration objectively satisfied the legal requirements for a serious assault under Finnish law.
