Questão jurídica principal
Whether the federal complaint met the reasoning requirements under Art. 42 BGG.
Decisão extraída
The complaint did not explain in a legally sufficient way why the cantonal judgment violated federal law.
Fundamentação extraída
A mere request for a different tax assessment and a global reference to prior pleadings do not satisfy the duty to state reasons in the complaint itself; new evidence could not cure this defect after the appeal deadline.
