Kernrechtsfrage
Whether the subsidary constitutional complaint was admissible and could be converted into a civil appeal
Extrahierter Entscheid
The constitutional complaint was inadmissible, but the filing could be treated as a civil appeal insofar as the statutory conditions were met.
Extrahierte Begründung
An opposition decision on seizure is a final cantonal decision subject to civil appeal when the amount in dispute exceeds the statutory threshold; it is also a provisional measure, so only constitutional rights may be invoked under the proper remedy.
