In the case analysed, the City Council would be obliged to communicate any information relevant to the purposes provided for in Article 22.2 LPD when there is a real danger to public safety or the investigation and prosecution of crimes by police forces. Although there is no explicit provision in the legislation studied on the obligation to formalise the request for information necessarily in writing, it is justified that the request for information from the police force be specified in writing, given the obligation incumbent on the City Council to comply with the principle of proactive responsibility. The communication of personal data without compliance with the principles of data protection may constitute an infringement of the aforementioned principles (Article 83.5 GDPR).
