Kernrechtsfrage
Whether the appeal could challenge the lower court's timing of the retroactive modification of spousal maintenance
Extrahierter Entscheid
The court found no constitutional violation in setting the retroactive effect from 1 October 2005 rather than 1 September 2005.
Extrahierte Begründung
Retroactivity in maintenance modifications generally starts no earlier than the date of the new request; further retroactivity requires special reasons, which were not sufficiently weighty here.
