Questão jurídica principal
Whether the cantonal remand judgment was an appealable decision under Art. 93 LTF.
Decisão extraída
The remand judgment was an incidental decision, and the appellant failed to show either irreparable legal harm or that immediate admission would avoid a long and costly evidentiary procedure.
Fundamentação extraída
The remand did not bind the office on the substantive assessment of the alleged aggravation or its effect on work capacity; a mere prolongation of proceedings is not irreparable harm, and the evidentiary steps required were not unusually long or costly.
