According to Article 17 of the GDPR, the data subject has the right to obtain from the controller the erasure of personal data concerning him or her without undue delay and the controller has the obligation to erase personal data without undue delay where one of the following grounds applies: (a) the personal data are no longer necessary in relation to the purposes for which they were collected or otherwise processed; (b) the data subject withdraws consent on which the processing is based and where there is no other legal ground for the processing; the data subject objects to the processing pursuant to Article 21(1) and there are no overriding legitimate grounds for the processing, or the data subject objects to the processing pursuant to Article 21(2); (d) the personal data have been unlawfully processed; (e) the personal data have to be erased for compliance with a legal obligation in Union or Member State law to which the controller is subject; (f) the personal data have been collected in relation to the offer of information society services referred to in Article 8(1). However, Article 17(3) provides that the right to erasure does not apply to the extent that processing is necessary for exercising the right of freedom of expression and information. Therefore, this would not be a valid ground for data subject delisting requests. Reference:
