unless such further information is not necessary to guarantee fair processing towards the data subject, taking into account the specific circumstances in which the data are collected,. a. further information, dependent on the specific nature of the processing, that will be specified by the King after advice of the Commission for the protection of privacy. The controller shall be exempt from the obligation to inform referred to in this paragraph: a. if, in particular for statistical purposes or for the purposes of historical or scientific research or for the purpose of public health screening with the intention of public health protection and promotion, the provision of such notification appears to be impossible or involves a disproportionate effort; b. if the recording or communication of personal data is carried out in view of the application of a provision laid down by or by virtue of a law, decree or ordinance. The King shall lay down in a decree agreed upon in the Council of Ministers after advice of the Commission for the protection of privacy, the conditions for the application of the previous section. [transitory provision] Article 10 § 1. The data subject proving his identity, has the right to obtain from the controller: a. confirmation as to whether or not data relating to him are being processed and information at least as to the purposes of the processing, the categories of data concerned, and the categories of recipients to whom the data are disclosed; b. communication in an intelligible form of the data undergoing processing and of any available information as to their source; c. knowledge of the logic involved in any automatic processing of data concerning him in the case of automated decisions referred to in Article 12bis; d. knowledge of the possibility to lodge an appeal referred to in the Articles 12 and 14 and, possibly, to consult the public register referred to in Article 18. For that purpose the data subject shall submit a signed and dated request to the controller or to any other person indicated by the King. The information shall be communicated immediately and no later than forty-five days after receipt of the request. The King may specify the modalities relating to the exercise of the right referred to in the first section. § 2. Any person shall have the right to get knowledge of the personal data that are processed relating to his health, either directly or with the assistance of a health professional. Upon request of the controller or of the data subject, communication may be done through mediation of a health professional who has been chosen by the data subject. If there is apparently no risk of offending against the privacy of the data subject and if the data are not used for taking measures and decisions with regard to an individual data subject, communication may be postponed if the health-related data are processed for purposes of medical scientific research, yet only to the extent that communication would interfere seriously with the research and no later than the moment on which the research is terminated. 9
