The state must have a compelling interest, like public safety, to violate her privacy rights. All citizens have the right for their personal information to not be publicly scrutinized without a very good reason.
What do you mean violate HER rights, she CHOOSE to put them on her government server which by law is under the control of the government and anything on it is government property. Yes there is good reason, so the person cannot destroy any government property and any classified emails are properly clear off it. That is why there are procedures to separate any private from official and it is done by a third party official NOT THE PERSON THEMSELVES.
Please don't tell me you are falling for her story.
