Questione giuridica chiave
Whether the Federal Supreme Court could review the challenge only as to direct federal tax and not the cantonal tax part
Decisione estratta
The complaint was admissible only for the direct federal tax; the part concerning cantonal tax was inadmissible for lack of final cantonal instance.
Motivazione estratta
The cantonal tax portion was not subject to a final cantonal decision, so the Court could not enter on that part.
