Supreme Court held that a defendant's lack of understanding during the crime negates criminal liability under Finnish law.

The Supreme Court of Finland dismissed the prosecution's appeal, ruling that the defendant was not criminally liable due to a lack of understanding at the time of the offense. The defense argued the defendant lacked the necessary mental capacity to comprehend their actions, while the prosecution contended the evidence did not prove this absence of understanding. The court found the evidence sufficient to establish that the defendant did not understand the nature of their acts, thereby exempting them from punishment.
