A decision set forth in the paragraphs of the preceding Article (hereinafter referred to as a "decision on ceasing to use personal information" in this Section) must be made within thirty days from the date of a request for ceasing to use personal information; provided, however, that in cases in which an amendment is requested pursuant to the provisions of Article 99, paragraph (3), the number of days required for the amendment is not included within that period of time.
Notwithstanding the provisions of the preceding paragraph, if there are justifiable grounds such as difficulties arising from conducting processes, an administrative organ's head or administrative entity may extend the period of time prescribed in that paragraph for up to thirty days. In this case, the administrative organ's head or administrative entity must notify the person making a request for ceasing to use personal information in writing of the extended period and the grounds for the extension, without delay.
