Question juridique clé
Whether the Federal Court could review the cantonal remand decision and the challenged findings of fact.
Solution extraite
The appeal was admissible because the remand order forced the tax authority to issue new decisions it could not later challenge; one factual omission had to be corrected.
Motifs extraits
A remand that binds the authority to a legally contested outcome creates irreparable prejudice under Art. 93 LTF. The cantonal court had arbitrarily omitted the founder's role as president and sole board member with individual signature, which was relevant to the civil-law assessment.
