Questione giuridica chiave
Whether the Federal Supreme Court could hear the case by administrative judicial review rather than constitutional complaint.
Decisione estratta
The challenged cantonal levy decision was based solely on cantonal law, so administrative judicial review was unavailable.
Motivazione estratta
A decision is reviewable by administrative judicial review only if federal public law forms the basis of the decision. A complaint that a cantonal tax levy conflicts with federal law must be raised, if at all, by constitutional complaint for violation of federal supremacy.
