The right to data protection gained autonomous fundamental rights status in the European legal space through Article 8 of the Charter of Fundamental Rights of the European Union. With the approval and enforcement of the General Data Protection Regulation (GDPR), this fundamental right obtained a framework of normative concretization that not only holds significant practical importance but also poses numerous implementation challenges for all interpreters dealing with the GDPR, especially within the framework of the Charter of Fundamental Rights. This work addresses the challenges posed by data protection law through a series of studies focused on the application of the GDPR in both public and private contexts. Although the predominant focus is on the GDPR in the Public Administration, there are also articles dedicated to topics that are either cross-cutting or have a greater impact on the private sector.
