Question juridique clé
Whether revision of a federal direct federal tax judgment is governed by the DBG revision rules or by the OG revision rules.
Solution extraite
Revision of federal judgments in direct federal tax matters is governed exclusively by the OG revision provisions; invocation of DBG revision grounds is inadmissible.
Motifs extraits
Art. 147(3) DBG refers revision of federal judgments to the OG, so only Arts. 136 ff. OG are relevant.
