Key legal question
Whether the appellant had standing to appeal the cantonal remand judgment concerning federal supplementary benefits.
Extracted holding
The appellant failed to show a legally protected economic interest affected by the remand judgment.
Extracted reasoning
The court held that the appellant did not establish concrete prejudice from the cantonal judgment. Since standing must be demonstrated by the appellant under Art. 89(1) and Art. 42 LTF, and no economic detriment was shown, the appeal was inadmissible.
