(1) Where there are facts which justify the assumption that providing information from the population register may result in a threat to the life, health, personal freedom or similar legitimate interests of the data subject or another person, then the registration authority is, on request or ex officio, to enter in the population register, free of charge, a block on releasing information. A similar legitimate interest is, in particular, the protection of the data subject or another person against threats, insults and stalking. When establishing whether facts within the meaning of sentence 1 exist, account is also to be taken of whether the data subject or another person belongs to a group of persons who are generally exposed to an increased level of hostility or other forms of aggression on account of their professional or voluntary activities.
(2) If, after hearing the data subject, a threat as referred to in subsection (1) cannot be ruled out, it is not permissible to provide information from the population register. If the data subject cannot be reached, then in the cases in which a block on releasing information was entered at the instance of one of the authorities referred to in section 34 (4) sentence 1 nos. 1 to 4, 6 to 9 and 11, the body at whose instance the block on releasing information was entered is to be heard. If no information is provided, the person or body requesting information receives notification which may not permit any conclusions to be drawn as to whether no information on the data subject is available or whether a block on releasing information exists.
(3) If a block on releasing information has been entered, the data subject and, if the entry was made ex officio at the instance of an authority referred to in section 34 (4) sentence 1 nos. 1 to 4, 6 to 9 and 11, the body at whose instance the block was entered is also to be informed without delay of any request for information from the population register.
(4) The block on releasing information is limited to two years. It may be extended on request or ex officio. The data subject is to be notified before the block is lifted if he or she can be reached. If the block was entered at the instance of one of the authorities referred to in section 34 (4) sentence 1 nos. 1 to 4, 6 to 9 and 11, then this authority is to be notified if the data subject cannot be reached.
(5) The provision of information from the population register is also not permissible
1. if inspection of a civil status register in accordance with section 63 (1) of the Civil Status Act may not be permitted and
2. in the cases referred to in section 1758 of the Civil Code.
