Question juridique clé
Whether the Federal Tax Administration could appeal the cantonal remand judgment immediately to the Federal Supreme Court.
Solution extraite
No. The remand decision was interlocutory and did not cause irreparable harm; the administration could challenge the new cantonal decision later through the available cantonal remedies.
Motifs extraits
The remand required further fact-finding on whether the expenses were actually incurred and in what amount, leaving discretion to the lower authority. Under Art. 93 LTF, no irreparable prejudice was shown, and the conditions for avoiding an onerous evidentiary procedure were neither alleged nor met.
