As regards those rights of the data subject, referred to in Directive 95/46, it must be noted that the protection of the fundamental right to respect for private life means, inter alia, that that person may be certain that the personal data concerning him are correct and that they are processed in a lawful manner. As is apparent from recital 41 in the preamble to that directive, it is in order to carry out the necessary checks that the data subject has, under Article 12(a) of the directive, a right of access to the data relating to him which are being processed. That right of access is necessary, inter alia, to enable the data subject to obtain, depending on the circumstances, the rectification, erasure or blocking of his data by the controller and consequently to exercise the right set out in Article 12(b) of that directive (see, to that effect, the judgment in Rijkeboer, C‑553/07, EU:C:2009:293, paragraphs 49 and 51).
