Questione giuridica chiave
Whether the Federal Supreme Court could enter into the IV office's appeal despite the cantonal court's warning under Art. 61 lit. d ATSG.
Decisione estratta
Yes. Admissibility before the Federal Supreme Court is governed by Art. 89 BGG; the cantonal withdrawal warning requirement does not control federal appeal standing.
Motivazione estratta
The procedural safeguards of Art. 61 lit. d ATSG apply to the cantonal phase only. Because the insured appealed first, the administration could request less than it had granted and, being unsuccessful below, was sufficiently aggrieved to appeal.
