Kernrechtsfrage
Whether the pre-2010 version of the Dumont practice still applied to the claimed maintenance costs
Extrahierter Entscheid
Yes. Because all claimed costs were incurred before 1 January 2010, the former modified Dumont practice remained applicable.
Extrahierte Begründung
The legislative changes abolishing the practice entered into force only on 1 January 2010 and did not apply retroactively.
