Thank you.
Of course, the government can change the security classification of names. There's a difference between changing classification and revealing classified information. However, I take your point that it would be an offence for a person who had access to classified information to reveal that information.
What about a case where a person might imply a name? Perhaps a person says, after reading the report, that they think a certain named person should not be allowed to join or remain in a particular caucus. Would that implied reference to a name be a criminal offence?
