Both the requirements of Article 18 and the obligation to inform about the utilisation purpose under Article 27 of the APPI are subject to the same set of exceptions, mostly based on public interest considerations and the protection of rights and interests of the data subject, third parties and the controller (37). According to the interpretation developed in the PPC Guidelines, those exceptions apply in very specific situations, such as where information on the utilisation purpose would risk undermining legitimate measures taken by the business operator to protect certain interests (e.g. fight against fraud, industrial espionage, sabotage).
