Regarding the relationship between the Act on the Protection of Personal Information and privacy, (1) the Act on the Protection of Personal Information includes the protection of privacy as its purpose, but it is not the only one, and (2) in the question of whether the substance of the invasion of privacy is questioned in a violation of the Act on the Protection of Personal Information, if there is a substantial invasion of privacy, it may be considered as a violation of the Act on the Protection of Personal Information (2-1), which is derived from the interpretation of the purpose provision and the prohibition of inappropriate use provision. As controversial points, there are the issues of whether a violation of the Act on the Protection of Personal Information is not a violation of the Act when there is no substantial invasion of privacy (2-2), whether a violation of the Act constitutes an invasion of privacy (3), and (3) can be further broken down into the question of whether a violation of the Act on the Protection of Personal Information constitutes an invasion of privacy (3-1) and whether a lawful act under the Act on the Protection of Personal Information can also prevent the violation of privacy (3-2). In a series of cases involving the submission of evidence of a list of discipline requesting parties, there have been judgments that a violation of the Act on the Protection of Personal Information is not a violation if there is no substantial invasion of privacy (2-2), and there have been a number of cases concerning 3-1 and 3-2.
