Kernrechtsfrage
Whether the municipality's challenge was time-barred despite the lack of remedies notice in the postal letters.
Extrahierter Entscheid
Even assuming the closure notice was an appealable decision, the municipality had to act within the usual 30-day period; waiting until 22 January 2002 was untimely.
Extrahierte Begründung
A recipient who receives a decision without remedies notice must inquire promptly. Good faith does not protect a party that remains passive. Here, the letters of 7 November 2001 clearly conveyed the decision and its effects, so the municipality should have acted within 30 days.
