Welcome to the section “Key Issues”. Under the various keywords you can find a brief introduction and the Articles of the GDPR as well as the recitals that are relevant to the topic. For more detailed information we compiled a list of links with expert contributions and opinions of the data protection authorities. The latter are also only a possible interpretation of the law which is not legally binding. The final interpretation of the GDPR is exclusively within the jurisdiction of the European Court of Justice. However, the opinions of the supervisory authorities are of considerable practical relevance due to their supervision through their investigative and corrective powers.
