Questão jurídica principal
Whether the taxpayer's complaint was admissible insofar as she sought review of the cantonal tariff itself and invoked unsubstantiated constitutional violations.
Decisão extraída
The complaint was admissible only for review of the concrete assessment; the direct challenge to the tariff as such was inadmissible, and the unsupported proportionality and federal-preemption claims were not examined.
Fundamentação extraída
A tariff can be reviewed only incidentally within the concrete case and only as far as the applicable norm is relevant. Broader abstract review of the cantonal tariff was time-barred. Unsubstantiated constitutional claims fail the pleading requirements.
