Questione giuridica chiave
Whether the cantonal court could rule on the waiver of restitution before a valid opposition decision on the restitution orders existed.
Decisione estratta
No. The waiver request could not be decided as if the restitution orders were already final; a proper opposition decision on restitution was missing.
Motivazione estratta
Under the LPGA, opposition is a mandatory prerequisite for administrative appeal. Because the appellant had challenged the repayment orders themselves, the office had to decide that opposition first. Without an appealable opposition decision on restitution, the cantonal court could not address the merits of restitution or waiver.
