Kernrechtsfrage
Whether the request for revision of the Federal Tribunal judgment was admissible before the Federal Tribunal under Art. 121 lit. d LTF.
Extrahierter Entscheid
No. The alleged ground concerned an issue that had not been part of the dispute before the Federal Tribunal; the request therefore had to be filed before the cantonal instance.
Extrahierte Begründung
Once the Federal Tribunal decides a public-law appeal on the merits, its judgment replaces the challenged decision and is the only enforceable decision susceptible to revision on the listed grounds. Revision before the Federal Tribunal is unavailable for matters outside the subject of the federal dispute.
