Question juridique clé
Whether the appeal against the cantonal remand decision was admissible as an appeal against a final or partial decision.
Solution extraite
The challenged judgment was an interlocutory remand decision, not a final or partial decision, and the conditions for immediate appeal were not met.
Motifs extraits
The cantonal court did not finally decide the tax assessment but sent the case back for further fact-finding. No irreparable harm or efficiency ground under Art. 93 BGG was shown; the appellants sought a different outcome on the merits, not merely review of the remand.
