Key legal question
Whether the cantonal remand judgment was appealable before the Federal Supreme Court
Extracted holding
The challenged cantonal decision was, as a whole, a non-appealable interlocutory decision; the appeal could not be heard.
Extracted reasoning
For the earlier period the case was remitted for further medical inquiries. For the later period, the court's merits ruling could not be separated from the unresolved earlier period because the pension claim is a single continuing legal relationship and a later phase cannot be definitively assessed before the earlier one is finally decided.
