Questione giuridica chiave
Whether the Federal Supreme Court could hear the appeal against the cantonal remand order under Art. 93 BGG
Decisione estratta
The appeal was admissible only to the extent that the remand order restricted the IV office's assessment margin and thus caused irreparable harm.
Motivazione estratta
A mere remand normally causes no irreparable harm, but it becomes appealable when the lower court binds the administration on a material issue in a way that forces a potentially unlawful decision.
