Question juridique clé
Whether the complaint was admissible and could be examined under the Federal Supreme Court Act.
Solution extraite
The appeal was in principle admissible, but the challenged non-harmonized cantonal tax assessment could only be reviewed for arbitrariness; the appellants' reasoning was largely insufficient.
Motifs extraits
The decision of the last cantonal instance fell under Art. 82 lit. a and Art. 86 Abs. 1 lit. d BGG. Because the tax years were still within the transitional period of the StHG, federal intervention was excluded under Art. 72 Abs. 1 StHG and review was limited to qualified arbitrariness allegations under Art. 106 Abs. 2 BGG.
