Personal identification number.
The decision followed up a 1991 decision of the Constitutional Court that declared unconstitutional the unlimited, general and uniform use of personal identification number (PIN). The Court also ruled that the collection and processing of personal data in the absence of a definite purpose and for arbitrary future use are unconstitutional. In the present ruling the Court delivered its opinion with reference to the use of the PIN in specific cases. It declared that a decision in a minor offence cannot contain the PIN of the delinquent. It declared also unconstitutional the obligatory use of two different systems of personal identification for the same purpose. This part of the decision concerned the use of two different PINs in a special identity card entitling to the use of social security services.
