Questione giuridica chiave
Whether the appeal against the remand order was admissible despite being a preliminary decision.
Decisione estratta
The remand order could cause an irreparable legal disadvantage because it bound the IV office to a disputed finding on work capacity and required a new decision on that basis.
Motivazione estratta
A remand decision normally only prolongs proceedings, but it becomes appealable when it materially restricts the lower authority's discretion and forces a legally contested new decision.
