This report analyzes the court cases from an intertemporal perspective. I have classified the court cases were into three categories according to the mode of distribution of information. The first; cases in which the distribution of information continued. Second; cases in which the distribution of information had ended. Third; cases in which the continuation of the distribution of information is unknown and the court did not consider it. I concluded that the Order of the Ministry of Internal Affairs and Communications, as amended in 2020, applies to earlier distributions of information. And such application should not be considered retroactive.
