Questão jurídica principal
Whether the appeal against the 2005 contribution recalculation was admissible despite the cantonal decision being interlocutory
Decisão extraída
The request concerning 2005 was inadmissible because the cantonal ruling was a non-appealable interim decision on remittal and the administration did not appeal.
Fundamentação extraída
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.
