Questão jurídica principal
Whether the federal appeal was admissible despite the appellant only seeking annulment and remand without quantifying the relief.
Decisão extraída
The filing satisfied the formal requirements because, if granted, the matter would have to be remitted to the cantonal authorities for recalculation of the contribution.
Fundamentação extraída
A concrete amount was unnecessary given the missing factual basis for precise quantification; a remand request was sufficient in this situation.
