Questão jurídica principal
Whether the federal appeal complied with the reasoning requirements of Art. 42 and Art. 106 LTF
Decisão extraída
Neither the original nor the supplemented appeal adequately engaged with the cantonal court's reasoning, so the appeal could not be examined on the merits.
Fundamentação extraída
The appellant merely restated his view on taxation of retroactively received AVS pensions and alleged arbitrariness, without showing why the challenged reasoning on taxation upon payment and on the inapplicability of the preferential rate was unlawful.
