20. Despite sections 17 and 18, a person concerned by information held by a body that has been provided by a third person does not have the right to be informed of the existence of or to have access to that information where disclosure of its existence or access to it would allow the third person to be identified, unless the third person has agreed in writing to the disclosure of the information and of its source to the person concerned.
The first paragraph does not apply where the information was provided by a service provider in the exercise of his or her functions.
