Whether D.________ was entitled to canton-level party costs after the Federal Court remand.
Yes. Having obtained partial success on the appeal, D.________ was entitled to party costs for the cantonal proceedings.
Under Art. 61 let. g LPGA and the cantonal tariff rules, a party with partial success may recover costs. The Federal Court's decision meant the appellant achieved at least partial success, even though the substantive status issue was not decided in his favor.
