The SC requires compliance with the GDPR from the moment data is collected
In this ruling, the Supreme Court has established that the mere request for personal data constitutes in itself a processing of data subject to the GDPR, regardless of whether or not the data subject provides them. In the case analysed, a penitentiary centre required a prison officer to provide his medical diagnosis and treatment to justify a three-day absence from work, despite the fact that he had already submitted the corresponding medical certificate. The High Court upheld the warning sanction imposed by the AEPD, considering that such a request was excessive and unnecessary for the control of absenteeism, thus violating the principle of data minimisation set out in Article 5.1.c) of the GDPR.
The practical implication of this ruling is relevant for any organisation, public or private: before requesting personal data, the controller must assess whether the request is adequate, relevant and proportionate to the purpose pursued, given that the mere fact of making the request triggers the set of obligations imposed by European data protection law.
