Questione giuridica chiave
Whether the appeal against the 2005 contribution recalculation was admissible despite the cantonal decision being interlocutory
Decisione estratta
The request concerning 2005 was inadmissible because the cantonal ruling was a non-appealable interim decision on remittal and the administration did not appeal.
Motivazione estratta
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.
