"but the Party convicted shall nevertheless be liable and subject to Indictment, Trial, Judgment and Punishment, according to Law."
I don't think this ruling is, on the surface, exactly what people are making it out to be. It certainly maintains a high bar for criminally prosecuting the president for something they do in office, but it is not allowing them to commit crimes with impunity.

Well it kind of does, because the president has the power to stop impeachment from ever happening in the first place, if they're willing to command the military to.
If we refuse to recognize that harm under the current Rule of Law, then who is going to identify and prosecute "harm" besides politically motivated ideologues? It sounds like a surefire way to cement the separation of the Executive office from it's respective checks and balances.
