Questione giuridica chiave
Whether the Federal Supreme Court could review the substantive income assessment of 2004.
Decisione estratta
No; the case before the lower courts concerned only the refusal to enter into the objection, so only that procedural issue could be reviewed.
Motivazione estratta
The subject matter of the appeal is limited by the scope of the challenged decision. Since the cantonal judgment dealt only with the admissibility of the objection, the merits of the assessment were outside the proceedings.
