Question juridique clé
Whether the cantonal commission rightly refused to examine the merits of the tax appeal for lack of proper conclusions and reasoning.
Solution extraite
Yes. The appeal filed at cantonal level did not cure the formal defects within the deadline, and the later reply could not substitute for timely conclusions.
Motifs extraits
The tax statutes require an appeal to contain conclusions. The commission warned the appellant and set a deadline to remedy the deficiencies. Since the supplemental filing did not contain relevant conclusions on the merits, refusal to enter into the merits was permissible and not excessive formalism.
