Question juridique clé
Whether the federal civil appeal met the value-of-dispute or principle-question requirements.
Solution extraite
The civil appeal was inadmissible because the aggregated tax claims did not reach CHF 30,000 and no question of principle was properly shown.
Motifs extraits
Interest claimed only as accessory did not count toward value; the complaint did not satisfy the strict requirements for a question of principle or the motivation duty.
