Kernrechtsfrage
Whether the appeal against the 2005 contribution recalculation was admissible despite the cantonal decision being interlocutory
Extrahierter Entscheid
The request concerning 2005 was inadmissible because the cantonal ruling was a non-appealable interim decision on remittal and the administration did not appeal.
Extrahierte Begründung
A remittal decision is an interlocutory decision under Art. 93 BGG; without a challenge by the administration, the Federal Court could not review the 2005 point.
