Key legal question
Whether the cantonal AHV/IV office had standing to appeal the alimony modification judgment
Extracted holding
The office lacked a legally protected interest and was not entitled to appeal in its own name.
Extracted reasoning
It pursued only its own financial interest in preventing higher future supplementary benefits, but this is not a legally protected interest under Art. 76 BGG; it was also not a federal authority under Art. 76(2) BGG and could not assert private-law interests of the debtor.
