The right of access is an important guarantee in the GDPR to ensure the transparency of data processing for data subjects. However, it is an open question to what extent this right can be exercised. In the past months, several interpretations became available, mostly from German data protection authorities and courts (see for example the decision of Cologne Regional Court summarised by Dr. Carlo Piltz, the judgment of the Higher Labour Court of Baden-Württemberg, the annual report of the Data Protection Authority of Hessen).
The Hungarian Data Protection Authority (in Hungarian: Nemzeti Adatvédelmi és Információszabadság Hatóság, the "Hungarian DPA") also issued several decisions that interpreted the rules of GDPR regarding the application of the right of access.
