In the case of Personal Data Recipients, in addition to the persons listed above, data can be made accessible to other persons, but only in the case that there will be legal grounds for access to that personal data (e.g. for law enforcement agencies, other monitoring bodies with legal basis for access to information), or should it be essential to protect the Administrator’s rights (e.g. in courts).
