In accordance with Act LXIII of 1992 on the protection of personal data and the publication of public data, data concerning sexual habits constitute sensitive data. This means that the purposes of the processing of that data must be clearly outlined and defined, and the processing of such of data must be unavoidably necessary.
The second sentence of Article 3.a of the Act XLVII of 1997 on the processing and protection of medical data (the Act) classifies in certain cases data concerning sexual habits as medical data. Article 4.1 of the Act enables medical staff to use this data for the sake of:
a. the preservation of health,
b. effective medical treatment,
c. keeping track of medical conditions, and
d. in the interest of public health and the country's epidemiological situation.
The processing of such data is not compulsory according to Article 12.1 of the Act; however, Article 13 makes it compulsory in certain cases.
The petitioner argued that the basic right to privacy and the protection of personal data set out in Article 59.1 of the Constitution were violated by the second sentence of Article 3.a of the Act.
The Constitutional Court found - after briefly reiterating its leading decisions in the field of data protection - that data concerning sexual habits constituted sensitive data, according to Act LXIII of 1992 on the protection of personal data and the publication of public data. That, in the opinion of the Constitutional Court, meant that the purposes of the processing of that data had to be clearly outlined and defined, and the processing of such data had to be unavoidably necessary.
Noting the purposes stated above of Article 4.1 of the Act, the Constitutional Court stated that the processing of data to serve the purposes (the medical treatment of the person in question) stated in a. to c. was not appropriate, as the effectiveness of medical treatment could be better served by the knowledge of data concerning the medical condition of the person in question than by the knowledge of data concerning his or her sexual habits. The public health and epidemiological interest stated in point d. of Article 4.1 may in theory justify the processing of sensitive data concerning sexual habits; however, the purpose of the processing of data has to be unambiguously and clearly outlined. The Constitutional Court stated that, in its opinion, not even those public interests met the requirements. Furthermore, under the Act, the processing of data concerning sexual habits for the purposes stated above is not only possible in relation to patients with sexual illnesses, but also in general.
According to the majority opinion of the Constitutional Court, the second sentence of the impugned Article 3.a of the Act provided for a definition that was broader than necessary for the processing of data concerning sexual habits. The processing of such data without a clearly defined purpose constitutes an unnecessary limitation of the basic right to the protection of personal data, and it is, therefore, unconstitutional. For this reason, the Constitutional Court struck down the sentence in question.
