Kernrechtsfrage
Whether the cantonal court correctly refused to hear the appeal as late-filed and whether reliance protection could excuse the missed deadline.
Extrahierter Entscheid
The appeal was filed one day after the statutory deadline, so the cantonal court rightly declined to enter into the merits; no protected reliance existed because no detrimental disposition was possible after expiry of the appeal period.
Extrahierte Begründung
The expected trust protection requires a prior detrimental disposition. Here, any confidence created by the court's later procedural conduct arose only after the appeal period had already expired and therefore could not affect timely filing.
