Kernrechtsfrage
Whether the appeal could reopen the merits of the final 2005 tax judgment in revision proceedings
Extrahierter Entscheid
No. Revision cannot be used to challenge the merits of a final judgment on grounds that could have been raised in an ordinary appeal.
Extrahierte Begründung
Revision targets only a final decision and is limited to legally defined revision grounds; post hoc attacks on the merits are inadmissible.
