(1) If the population register is inaccurate or incomplete, the registration authority is required to rectify or complete (update) it as required by Article 5 (1) (d) of Regulation (EU) 2016/679. Those public bodies to which the inaccurate or incomplete data have been transferred in the context of regularly occurring data transfers are to be informed without delay of such rectifications and updates.
(2) If the public bodies referred to in subsection (1) sentence 2 do not carry out tasks of official statistics or are not religious communities under public law, they are to inform the registration authorities without delay if they have specific reasons to believe that the transferred data are inaccurate or incomplete. Public bodies to which registration data have been transferred at their request are to inform the registration authorities if they have such specific reasons. Legal obligations of secrecy, especially tax secrecy pursuant to section 30 of the Fiscal Code of Germany, as well as professional or special official secrecy do not prevent them from doing so as long as the information provided is limited to the fact that there are specific reasons to believe that the transferred data are inaccurate or incomplete.
(3) If the registration authority has specific reasons to believe that the population register contains inaccurate or incomplete information, it is to investigate the matter ex officio.
(4) When forwarding data and remarks in accordance with section 37, subsection (1) sentence 2 and subsection (2) apply accordingly.
