Questão jurídica principal
Whether the complaint against the cantonal tax court decision was admissible, including insofar as it sought annulment of the underlying assessments.
Decisão extraída
The complaint was admissible against the last cantonal-instance judgment, but inadmissible to the extent it directly challenged the assessment decisions.
Fundamentação extraída
Federal public-law appeal lies against final cantonal decisions; the underlying assessment rulings are not themselves the proper object of appeal here.
