Question juridique clé
Whether the complaint was admissible against the cantonal remand decision and the later IV decision
Solution extraite
The complaint was inadmissible because no final decision existed yet and the cantonal remedies stage was not exhausted, especially for the IV decision.
Motifs extraits
Art. 93 para. 3 BGG did not help, since that provision presupposes a subsequent final decision; the case was again pending before the cantonal court. In addition, the requirement of a cantonal final instance under Art. 86 para. 1 lit. d BGG was missing.
