This treatise is a comment on judgments or precedents decided by highest co urt in view of the theory of crime concurrence. Therefore those sentences of co urt are divided into several categories and reviewed and criticized thoroughly in the ways of group or case by case. Among them we differentiate the concurrence in crimes and concurrence in laws from the pseudo-concurrence of crime. The concept of crime concurrence are often misunderstood and misused in judgment by district court, high court or even highest Court. The aims of this treatise are purposely to remind judges to pay more attention on it.
