Questione giuridica chiave
Whether the appeal was sufficiently reasoned under Art. 42 and Art. 106 BGG
Decisione estratta
The appeal did not engage with the decisive reasoning of the cantonal court and therefore failed the federal reasoning requirements.
Motivazione estratta
The appellants attacked the tax merits and alleged arbitrariness, but the dispute before the Federal Court concerned only whether the authorities had to revisit a final estimated assessment; their submissions did not address the cantonal court's procedural reasoning.
