The Anti-Fraud Office Law establishes that if the possibility of involvement in the facts of a person who holds a high position or is an official, manager, member or employee of an institution, body or an entity included in the scope of action of the Office, this person will be informed of the investigation. The Office cannot formulate or issue personalized conclusions or make nominal references in its reports and reasoned expositions if the person concerned has not previously had the real possibility of knowing the facts, so that he can at the same time record his opinion on the facts that directly or indirectly affect him/her. On the other hand, if the Office's investigations affect people who hold high positions, officials, managers or employees, then the person responsible for the institution, body or entity who they depend on or what services they provide must also be informed.
