Questão jurídica principal
Whether the appeal against the remand judgment was admissible under Art. 93 BGG
Decisão extraída
The appeal was admissible only insofar as it challenged the binding instruction to assess invalidity by the income-comparison method; it was inadmissible against the mere remittal for further medical investigations.
Fundamentação extraída
A remand order is an independently appealable interim decision only if it may cause irreparable legal harm or if immediate allowance would end the case and avoid extensive evidence. The challenge to further medical inquiries did not meet these requirements, but the binding methodological instruction did, because it constrained the administration's discretion.
