Questão jurídica principal
Whether the Federal Supreme Court could review the challenge only as to direct federal tax and not the cantonal tax part
Decisão extraída
The complaint was admissible only for the direct federal tax; the part concerning cantonal tax was inadmissible for lack of final cantonal instance.
Fundamentação extraída
The cantonal tax portion was not subject to a final cantonal decision, so the Court could not enter on that part.
