Kernrechtsfrage
Whether a later request to modify maintenance must be assessed against the last final decision rather than the original interim order.
Extrahierter Entscheid
On a repeated modification request, the court must generally compare the situation with the last final decision, not with the original interim order, especially when the same grounds were already examined and rejected.
Extrahierte Begründung
A modification request cannot serve as a substitute for an omitted appeal. If the same reasons were already addressed in a final decision, repeating them is merely criticism of that judgment and does not establish a new modification ground.
