Yes. In fact, we ask every member of the National Assembly or member of Parliament who receives the list to sign an undertaking that the confidentiality of that list will be maintained and that they will ensure it is used only for the purposes for which it was designed.
People have complained in the past about the fact that their elective representative called them to wish them a happy birthday or had sent them a birthday card after obtaining their personal information through the electoral list. That has happened only a couple of times. When it did, I called the member myself and let him know he could not use the list for that purpose.
