Kernrechtsfrage
Whether the new federal appeal against the cantonal costs ruling was filed within the statutory time limit.
Extrahierter Entscheid
The appeal was filed too late, because the appellant had to act within 30 days of the new municipal decision or, at the latest, within 30 days after the prior Federal Supreme Court judgment.
Extrahierte Begründung
A favorable new municipal decision reopened the possibility to challenge the cantonal costs ruling, but not indefinitely. Under Art. 100(1) LTF, the time limit had expired before the December filing. The alternative view as a request for revision also failed because the 90-day revision period under Art. 124(1)(d) LTF had lapsed.
