Ben, as usual, you are guessing.On its face, this refers to threats of force or other unlawful acts, not threat of proper legal action.
Are you saying you cannot legally threaten sanctions and/or prosecution against a public employee who refuses to do their job?
I had 17 criminal prosecutions against me, and I m a lawyer, for using a legal institute called pronto despacho that is an ultimatum to the judge before starting legal actions.
I was found non guilty in 5 seconds but, however, the Prosecutor accused me of aggravated coercion that has automatic preventive prison. So, I faced the risk of jail for doing what you happily advice in your ignorance.
However, my lawyers were two heavy weights of the Federal Courts. One of them is the lawyer of the Presidents, the other is who prosecutes Federal Judges.
So, in my esperience, you cannot do that. You have to make the criminal complaint and the dismissal case first and later just to notify them in a very polite way.
