We don’t have a list of things you can say about a person without intruding on their privacy.There is no check list of what is acceptable and what is not.
Courts judge what is said, and why, on an individual basis, taking account of the character and behaviour of the complainant.
The courts' view of what is and is not acceptable has changed over recent years.
