(1) If in the case of non-automated data processing erasure would be impossible or would involve a disproportionate effort due to the specific mode of storage and if the data subject’s interest in erasure can be regarded as minimal, the data subject shall not have the right to erasure and the controller shall not be obligated to erase personal data in accordance with Article 17 (1) of Regulation (EU) 2016/679 in addition to the exceptions given in Article 17 (3) of Regulation (EU) 2016/679. In this case, restriction of processing in accordance with Article 18 of Regulation (EU) 2016/679 shall apply in place of erasure. The first and second sentences shall not apply if the personal data were processed unlawfully.
(2) In addition to Article 18 (1) (b) and (c) of Regulation (EU) 2016/679, subsection 1, first and second sentences shall apply accordingly in the case of Article 17 (1) (a) and (d) of Regulation (EU) 2016/679 as long and as far as the controller has reason to believe that erasure would adversely affect legitimate interests of the data subject. The controller shall inform the data subject of the restriction of processing if doing so is not impossible or would not involve a disproportionate effort.
(3) In addition to Article 17 (3) (b) of Regulation (EU) 2016/679, subsection 1 shall apply accordingly in the case of Article 17 (1) (a) of Regulation (EU) 2016/679 if erasure would conflict with retention periods set by statute or contract.
