Answering a Legal Question about Summary Proceedings

Questioner

If a judge in summary proceedings has ruled on a certain point in my favor. (I was summoned to court.) And the plaintiff/opposing party who lost the summary proceedings has not appealed afterwards. And 3 months later the opposing party decides that they have found a vague rule in the law somewhere (which makes no sense, but that is not so important for this question). Can they then go to court again for this point? The other party is threatening to do so now. But I don't think that's possible at all, right? Or is that a difficult question?

Lawyer

If the appeal period has expired, an appeal against the summary judgment is not possible. At the same time, however, summary proceedings are a provisional disciplinary measure that must yield to a ruling in substantive proceedings. This means that if the other party starts substantive proceedings and you lose them, the summary judgment loses its effect, even if no appeal was lodged against it.
