Key legal question
Whether the cantonal remand judgment was appealable before the Federal Supreme Court despite being interlocutory.
Extracted holding
The remand judgment was an interlocutory decision and the appeal was inadmissible because the Office showed no irreparable harm.
Extracted reasoning
A remand for further investigation and a new decision leaves the administration full freedom in the later merits decision. The need to obtain additional expert evidence, even outside the regional medical service, does not by itself create irreparable prejudice.
