Questione giuridica chiave
Whether the taxpayers were denied the right to be heard by refusal of an oral hearing and appointment of a bookkeeping expert
Decisione estratta
No violation of the right to be heard was found; neither a general right to an oral hearing nor a right to an external bookkeeping expert existed on these facts.
Motivazione estratta
The taxpayers had multiple opportunities to submit written and oral comments during the tax and objection stages, and the authorities could, in anticipatory assessment, conclude that further evidence would not change their view. The cantonal provisions did not extend the federal minimum guarantee.
