Key legal question
Whether the federal appeal against the cantonal remand decision was admissible under Art. 93 BGG.
Extracted holding
The remand decision caused an irreparable legal disadvantage for the administration because it bound the IV office to grant a pension it considered unlawful.
Extracted reasoning
The cantonal judgment contained materially binding findings on the quarter pension; after the later determination of start date and amount, the pension entitlement itself could hardly be challenged anymore.
