Decision 15/1991 on the use of personal data and the personal identification number
13 April 1991
Decision number: Decision 15/1991. (IV. 13.)
Subject of the case:
The use of personal data and the personal identification number
In the absence of a definite purpose and for arbitrary future use, the collection and processing of personal data is unconstitutional. The right to the protection of personal data, known as the right to informational self-determination, as guaranteed under Article 59 of the Constitution, permits everyone the freedom to decide about the disclosure and use of their personal data to the extent that the approval of the person concerned is generally required to register and use it. In addition Article 59 of the Constitution ensures that such person can monitor the entire route of data processing thereby guaranteeing the right to know who used the data and when, where and for what purpose it was used. A statute could exceptionally require the compulsory supply of personal data and prescribe the manner of its use provided it complied with Article 8 of the Constitution.
