Question juridique clé
Whether the federal appeal was admissible despite no appeal to the competent cantonal higher court.
Solution extraite
The appeal was inadmissible because the cantonal instance path had not been exhausted; the tax court was not a higher cantonal court within Art. 86 BGG.
Motifs extraits
After the transitional period, Art. 86(2) BGG requires access to an upper cantonal court. Under Basel-Landschaft tax law, the proper cantonal remedy lay to the Cantonal Court, not directly to the Federal Supreme Court.
