Kernrechtsfrage
Whether a valid definitive enforcement title existed for the 2015 municipal tax debt.
Extrahierter Entscheid
A valid title existed only for the amount of CHF 51.75 contained in the debtor’s own tax assessment; no valid title existed for CHF 52.15 or additional interest.
Extrahierte Begründung
The assessment reprinted for the legal-opening file with a higher automatically added interest amount had not been shown to have been served and did not qualify as an enforcement title. The debtor’s own copy, expressly marked as a final assessment and not challenged, did.
