Kernrechtsfrage
Whether the revision request was admissible under Arts. 121-123 BGG.
Extrahierter Entscheid
The request was inadmissible because it alleged only criticism of the costs fixed in the earlier judgment, not a statutory ground for revision.
Extrahierte Begründung
Revision grounds are exhaustively listed in Arts. 121, 122 and 123 BGG. A mere challenge to the amount of court costs is not a permissible revision ground.
