Key legal question
Whether the cantonal remand decision was independently appealable under Art. 93 BGG
Extracted holding
No. The remand order did not cause irreparable legal harm and did not justify immediate review as an exception for avoiding extensive evidentiary proceedings.
Extracted reasoning
The order only required supplementary medical evidence and a new decision. Such a remand usually can be challenged later with the final decision, and the required exception under Art. 93 Abs. 1 lit. a or b BGG was not met.
