The second category has been further specified in Article 5 of the Cabinet Order. Read in conjunction with Article 2(7) of the APPI, it exempts from the scope of the notion of retained personal data, and thus from the individual rights under the APPI, those personal data that are "set to be deleted" within a period of six months. The PPC has explained that this exemption aims at incentivising business operators to retain and process data for the shortest period possible. However, this would mean that EU data subjects would not be able to benefit from important rights for no other reason than the duration of the retention of their data by the concerned business operator.

In order to address this situation, Supplementary Rule (2) requires that personal data transferred from the European Union "be handled as retained personal data within the meaning of Article 2, paragraph 7 of the Act, irrespective of the period within which it is set to be deleted". Hence, the retention period will have no bearing on the rights afforded to EU data subjects.

As under the Supplementary Rules personal data transferred from the European Union will be considered "retained personal data" irrespective of their retention period (unless covered by exemptions), they will always be subject to the transparency requirements under both of the aforementioned provisions.

Although not all provisions of Chapter IV, Section 1 of the APPI are listed in Article 42(1) – which also determines the scope of application of Article 42(2) – this can be explained by the fact that certain of those provisions do not concern obligations of the PIHBO (59) and that all essential protections are already afforded by other provisions that are included in that list. For instance, although Article 15 (requiring the PIHBO to set the utilisation purpose and process the relevant personal information exclusively within its scope) is not mentioned, failure to observe this requirement can give ground to a recommendation based on a violation of Article 16(1) (prohibiting the PIHBO to process personal information beyond what is necessary to achieve the utilisation purpose, unless it obtains the data subject's consent) (60). Another provision not listed in Article 42(1) is Article 19 of the APPI on data accuracy and retention. Non-compliance with that provision can be enforced either as a violation of Article 16(1) or based on a violation of Article 29(2), if the individual concerned asks for the correction or deletion of erroneous or excessive data and the PIHBO refuses to satisfy the request. As regards the rights of the data subject according to Articles 28(1), 29(1) and 30(1), oversight by the PPC is ensured by granting it enforcement powers with respect to the corresponding obligations of the PIHBO laid down in those Articles.

First, with respect to personal information collected by Administrative Organs, the latter are under an obligation to "endeavour to properly and expeditiously process any complaints" regarding its subsequent processing (Article 48 of the APPIHAO). While Chapter IV of the APPIHAO on individual rights is not applicable with respect to personal information recorded in "documents relating to trials and seized articles" (Article 53-2(2) of the CCP) – which covers personal information collected as part of criminal investigations – individuals may bring a complaint to invoke the general data protection principles such as for instance the obligation to only retain personal information "when the retention is necessary for performing [law enforcement functions]" (Article 3(1) of the APPIHAO).
