Land register number allows access to personal data, Polish authorities confirm
In a legal dispute that has been ongoing since 2020, the Polish Commissioner for Human Rights recently stated that the disclosure of land register numbers can lead to obtaining a large amount of personal data contained in the registers. In his opinion, general access to such detailed data harms and significantly restricts the informational autonomy of individuals.
The Commissioner’s view confirms the position of the Polish Data Protection Authority, which, in an administrative decision dated August 24th, 2020, ordered the Polish General Surveyor to cease making land register numbers available on the website “GEOPORTAL2”. He also imposed a fine of PLN 100,000 for violating the principle of lawfulness under Articles 5 para. 1 lit. a, 6 para. 1 GDPR, as there was no legal basis for the processing.
The decision was justified by the fact that land register numbers allow indirect identification of property owners and are therefore considered personal data. Moreover, the publication of these enables access to further data such as national ID number or property address. This may lead to a variety of dangers associated with the use of such data, in particular identity theft or impersonation for criminal purposes.
This opinion was also held by the Polish Voivodeship Administrative Court in Warsaw, which on May 5th, 2021, dismissed the Surveyor’s complaint against the decision of the Polish Data Protection Authority.
