Key legal question
Whether the Federal Supreme Court could hear the appeal against the cantonal remand decisions.
Extracted holding
The challenged remand decisions were interlocutory; the appellant failed to show irreparable harm or immediate finality under Art. 93 BGG.
Extracted reasoning
The remand required the tax commission to determine the imputed rental value and was not a mere arithmetic implementation. The appeal did not address the admissibility requirements of Art. 93 BGG.
