No effect shall be given to a request referred to in § 1 and § 2 but after expiration of a reasonable period of time, counting from the date of a prior request of the same person that has been answered or from the date on which the data have been disclosed to him on own initiative. Article 11 [cancelled] Article 12 Any person shall have the right to obtain free of charge rectification of inaccurate personal data relating to him. In addition any person shall have the right to object against the processing of data relating to him for serious and legitimate reasons that have regard to his particular situation, unless the lawfulness of the processing is based on grounds referred to in Article 5 b) and c). If personal data are obtained for purposes of direct marketing the data subject may object free of charge and without any grounds against the intended processing of personal data relating to him. In case of legitimate objection the processing carried out by the controller may no longer relate to these personal data. Any person shall also have the right to obtain free of charge the erasure of all personal data relating to him or the prohibition of using such data that are incomplete or irrelevant in view of the purpose of the processing, or of which the recording, communication or storage are prohibited, or that have been stored longer than the authorised period of time. § 2.

If the data subject objects against the processing or the intended processing of personal data relating to him in application of § 1, first and second section, the controller shall communicate within the same period of time to the data subject which effect he has given to the request. § 4.
