Article 100Obligation for Ceasing to Use Personal Information an Administrative Entity Holds

第百条（保有個人情報の利用停止義務）

When a request for ceasing to use personal information is filed, and an administrative organ 's head or administrative entity finds that there are grounds for the request, the head or entity must cease to use the personal information the administrative entity holds that is subject to the request within the scope necessary for ensuring the proper handling of personal information in the administrative entity to which the administrative organ's head or administrative entity belongs; provided, however, that this does not apply if it is found that ceasing to use the personal information the administrative entity holds is likely to hinder the proper execution of the process or service relating to the purpose of use of that personal information due to their nature.

行政機関の長等は、利用停止請求があった場合において、当該利用停止請求に理由があると認めるときは、当該行政機関の長等の属する行政機関等における個人情報の適正な取扱いを確保するために必要な限度で、当該利用停止請求に係る保有個人情報の利用停止をしなければならない。ただし、当該保有個人情報の利用停止をすることにより、当該保有個人情報の利用目的に係る事務又は事業の性質上、当該事務又は事業の適正な遂行に著しい支障を及ぼすおそれがあると認められるときは、この限りでない。
