Kernrechtsfrage
Whether the public-law appeal was filed within the statutory time limit.
Extrahierter Entscheid
The appeal period runs from notification of the challenged decision, not from later communication of remedies; the appeal was therefore late.
Extrahierte Begründung
No legal duty to indicate remedies existed for this extraordinary remedy, and the later letter did not amount to a new decision, correction, or supplementation that would restart the deadline.
