Questão jurídica principal
Whether the constitutional complaint met the reasoning requirements for an arbitrariness challenge.
Decisão extraída
No. The complaint did not adequately explain why the cantonal judgment was arbitrary and did not engage with key reasons on goodwill and proof.
Fundamentação extraída
Under Art. 90(1)(b) OG, only expressly raised and sufficiently reasoned complaints are examined. The taxpayers' only arbitrariness argument was factually misplaced, and they ignored other decisive grounds of the cantonal decision.
